Selecting the right variable spring hanger for a piping system is a critical task that ensures the system's integrity, safety, and efficiency. The method involves several steps, from understanding the system's requirements to selecting and validating the appropriate hanger. Here's a detailed approach to selecting a variable spring hanger:

Step 1: Gather System Requirements

Understand the Piping System: Analyze the layout, including size, weight, and the type of fluid it carries.

Identify Load Conditions: Determine the maximum and minimum loads that the hanger must support, including the weight of the pipe, insulation, contents, and any attached equipment.

Determine Movement Requirements: Calculate the expected thermal expansion and contraction, as well as any other movements (e.g., due to seismic activity or operational dynamics).

Step 2: Analyze Thermal Expansion and Load calculation

Calculate Thermal Movement: Use the coefficient of thermal expansion for the pipe material, along with the temperature range, to calculate the total expected movement.

Consider System Flexibility: Assess the system's flexibility to ensure it can accommodate the thermal movements without undue stress.

Step 3: Select Hanger Type

Choose Between Variable and Constant Support: Based on the system's movement and flexibility, decide whether a variable spring hanger (which provides a variable force as the pipe moves) or a constant support hanger (which provides a constant force) is more suitable.

Step 4: Determine Spring Characteristics

Select Spring Rate: Choose a spring with a rate (force per unit movement) that can support the load within the expected movement range without exceeding the allowable stress limits of the pipe.

Calculate Allowable Variation: Ensure the selected spring's load variation is within acceptable limits throughout its range of movement to avoid excessive stress on the piping.

Step 5: Evaluate Installation Conditions

Assess Space and Access: Ensure there is enough space for the hanger and that it can be easily accessed for maintenance and adjustment.

Environmental Considerations: Select materials and coatings for the hanger that are suitable for the operating environment to prevent corrosion and degradation.

Step 6: Finalize Selection

Vendor Specifications: Review and compare specifications from various manufacturers to find the hanger that meets the system's requirements.

Compliance with Standards: Ensure the selected hanger complies with relevant standards and regulations.

Step 7: Installation and Testing

once when i was just barely a teenager i was putting my grandfathers very expensive acoustic back on its wall hanger

his studio room was pretty small and had very low ceilings with a fan, and i was so so focused on not bumping the guitar on furniture so i lifted the guitar up to clear a table and heard a massive bang from above and instinctively yanked it back down to assess the damage while trying to come up with ways to explain to my grandpa that i broke his $2000+ guitar.

fortunately, there was a spring capo on the headstock, which is what hit the fan, with no damage to the headstock; regardless, i have never felt more fear while handling an instrument, and since then i have been extremely conscious of paying attention to all variables while moving guitars.

#i still toss my guitars around like theyre sandbags though idgaf

6 Easy Steps to Find The Best Spring Hangers For Your Plumbing Project

Spring hangers do an excellent job holding up pipe systems and eliminating their noise in hospitals, hotels, and more. You need professional acoustics and dampening engineers to find the perfect pipeline isolation design.

Here are six aspects that these highly dependable manufacturers do to provide exceptional vibration reduction.

Heat Load and Pipe Movement

Pipe movement is minimal but significant in residential and commercial properties. Hot water passes through the pipes creates much more noise because of its intense pressure. Therefore, hot water load influences pipe movement.

Travel Range

Hot water can completely navigate through a pipe system and cause massive vibrations because of its massive density. Therefore, your spring hangers must have enough travel range to reduce vibration sufficiently.

The Right Midrange Spring Use

Midrange springs are perfect for hot load pipe travel paths because they can endure the heat and introduce enough vibration isolation. In doing so, it achieves exceptional noise and vibration reduction and ensures a steady liquid flow the entire time.

Spring Hanger Variability

Non-crucial applications and systems can have 25% variability between their spring hangers for optimal vibration reduction. On the other hand, steam pipes, turbines, and other critical components must only have 10% variability to ensure their long-term performance and dependability.

Spring Type According to Space

Limited space will render your perfect spring hanger choice problematic and transmit vibration and noise by colluding with walls consistently. Therefore, have ideal options but measure the pipe pathways before finalizing your choice of spring hangers.

Hanger Material Resistances and Resilience

Pipes have corrosive chemicals and substances that can cause advanced corrosion and other issues. Therefore, consider the material's resistance, resilience, and price before finalizing your spring hanger options.

Photoshoot of the Week: February 17th-23rd 2020 - Ducati Monster 821 & Stefania

These days, the best urban motorcycles are those that can navigate, cut through traffic, and place you at the head of the mid-morning rush with ease. Acceleration and speed are nice qualities to have, but they take a back seat to mobility, compactness, and fuel economy. When looking for the perfect inner-city cycle, you’ll need something that can fulfill all these elements with ease, while also offering you a bit more in terms of safety and manageable speed. Without any doubts cool Italian bikergirl and impressive socialite Stefania made the right choice: Ducati Moster 821. The smoothness and precision of this bike make it feel as though you are always in control. In the city, this bike is able to handle everything an urban rider can through at it. It is very balanced at slow speed and does not give you the feeling that it will topple. It steers with minimal effort and is able to avoid hazards and obstacles with very little effort. The Monster runs perfectly in the city, despite all of the “stop and go traffic” and endless idling. Besides, if you leave the city to head out of town, you'll be not disappointed, again. Just try out the touring setting: once set, it reminds you to let off on the throttle to engage the mode. It's like switching to a different motorcycle: the motorcycle immediately feels more responsive and the acceleration become more immediate. Everyone who tryed the Monster can tell you how agile this bike is in the twisties and how responsive it was on the straights: the touring setting highlighted the torque of the bike. Riding a Ducati Monster 821 definitely puts a smile on your face, as you can see from fascinating Stefania's posts on Instagram. I think that legendary actress Mariyn Monroe once said that "a smile is the best makeup any girl can wear". Well, I think that's so true, but such an amazing bike can also play its part! Am I right people? *** *** *** The Monster 821 pays homage to the legacy of the Monster 900, which over 25 years ago revolutionised the motorcycle world. Agile and featuring sporty performance, it was designed for maximum riding enjoyment, at all times and in all conditions. The Monster 821 range has been rejuvenated with a new stealth version: matte black livery, updated graphics and front fairing give a unique character to the naked Ducati par excellence. The standard equipment, which includes adjustable fork and Ducati Quick Shift up/down, makes it even more effective on the road. Now, the Monster 821 has been upgraded to include aesthetic and functional features first introduced on the Monster 1200: a more streamlined, agile look with fully redesigned tank and tail, an all-new silencer and a headlight that is both classic and contemporary. Also making its debut on the mid-size Monster is the colour TFT display with selected gear and fuel indicators, while available accessories include the Ducati Quick Shift up/down system. The Euro 4 compliant liquid-cooled Testastretta 11° engine delivers a maximum power of 109 hp (80 kW) at 9250 rpm. Thanks to its 8.8 kgm (86 Nm) of torque at 7750 rpm, the 821 offers exciting performance, easy riding and unmatched fun. A beefy front end, exposed Trellis frame, and tiny tail give the Monster 821 an all-up-front look that just accentuates its aggressive nature and makes it look kinda like a big cat about to pounce. Fans of the family will likely recognize the round headlight and fuel tank as the same used by the Monster 1200 with a very special detail in the tank clip that hails back to the family’s origins in 1992. A short-rise handlebar lets you push off for a near-vertical posture in a relaxed attitude with plenty of room to tuck in over the curve of the fuel tank for those times when you’re feeling a little more aggressive. The rear of the tank tapers to a narrow waist ahead of the deep-scoop saddle to form a knee pocket that pulls the leg in out of the slipstream and gives you a knee-hanger if you’re inclined to do a little pegdragging. An adjustable saddle gives you a choice in seat height with a 30.9-inch setting and a 31.8-inch one without having to change the seat or suspension components. Behind the pilot, a monochrome cover disguises the two-up nature of the seat with subframe-mount, flip-up footpegs to complete the pillion gear. Tubular-steel members make up the Trellis frame on the Monster 821 Stealth, and as you’d expect, the engine is a stressed unit that completes the assembly and replaces a significant chunk of frame in the downtube/cradle area to reduce weight. Aluminum is the material of choice for the yoke-style swingarm to minimize unsprung weight at the rear axle. Toward that end, a set of 17-inch, cast-alloy wheels round out the rolling chassis with a 10-spoke design and Pirelli’s Diablo Rosso III hoops to make the connection to the pavement. The hoops are typical of the genre at 120/70 up front and 180/55 out back, and they get all kinds of help from the electronics to make this a relatively safe ride. The Monster 821 Stealth comes with the Ducati Safety Pack that includes delightfulness such as the aforementioned ABS and Traction Control alongside variable power-delivery Power Modes and a Quick Shift feature that let’s you bang out clutchless shifts both up and down the range. An anti-hop slipper clutch couples engine power to the six-speed transmission, and it provides one final layer of protection for the rear contact patch. Said power measures in with some fairly impressive numbers. Ducati’s Testastretta pumps out 109 horsepower at 9,250 rpm with 63 pounds of torque that top out at 7,750 rpm. Twin, 88 mm bores run with a 67.5 mm stroke for a total of 821 cc and a sizzlin’ 12.8-to-1 compression ratio, and as usual, Duc’s Desmodromic valvetrain times the four-valve heads with a pull-closed cam rather than coil springs to seal the combustion chamber. The bike maintained it’s smooth acceleration, but it was undeniable that this machine has the heart of a racer. This is where the steel trellis frame highlighted the precision that is undeniably Ducati. With very little effort, I was able to pass slower traffic. At no time did I find that I was not in control of the bike. The Monster 821 played its role very well in allowing me to experience the road in a very exhilarating and fun way. It is a powerful motorcycle; however, it is very smooth and predictable as one would expect from a twin cylinder engine. The relatively flat torque curve and the 109 horsepower combined with the weight of this motorcycle gives it a finely tuned feeling that Ducati is known for. I would recommend the Monster 821 to everyone. It is an awesome machine that I hope to have a chance to ride again soon ... maybe with Stefania? #bikergirl #Monster821 #ducatiobsession #ducatilife #motorcycle #ducatista #ducatinsta #superbikes #ducativ4 #ducatimonster821 #ducatiSuperSport #ridefast #bikeracing #motosports #motolife #fastbikes #RidinGirlsBlog #racing #motorbike #bikersofinstagram #bikerfamily #biketouring #riderich #girlsonbikes #hjc #sportbike #sexybiker #bikerchick #bikerlady #desmo #speed #roadracing #ridingsexy #superbike #motard #ducaticorse #motorrad #ducati #motogp #moto #helmetporn #ducatimonster #ducatiracing #turin #monster600 #monster797 #v4

Next Generation

In a video presentation offering insight to the technology on show at ITMA Asia, Shima Seiki outlined how it has been presenting its WHOLEGARMENT technology under the MACH2 name for the last 14 years https://sites.google.com/view/theywayofknitting.

"Now we have decided to go back to the origin of WHOLEGARMENT and use the SWG X name used on the very first machine," the company said.

"X stands for four needle beds arranged in an X-shaped formation as per the original SWG-X machine, while the R stand for 'Reborn and Revolution', referring a renewal of WHOLEGARMENT technology that raises it to unprecedented levels."

At the show, Shima Seiki is demonstrating just how much the technology has evolved and improved.

By renewing various functions of the machine SWG-XR boasts significant increases in productivity. At the same time, Shima Seiki has added various new functions that allow the production of designs that could not be knitted previously.

Samples demonstrating this have been shown live but also virtually and include one piece dresses in both long sleeve and short sleeve can be knit in significantly less time - up to 25 per cent for the long sleeve and 32 per cent for the short sleeve.

This is performed with double knitting, which is made possible through the use of four systems on the new SWG XR machine.

Intarsia knitting, which had been considered unsuitable for WHOLEGARMENT due to long knitting times is also now made practical with this machine with the use of auto yarn carriers leading to a knitting time reduction of 65 per cent.

"We will continue to research possibilities for using even more colours in the future," Shima Seiki said.

The advancements in the technology are also illustrated by three further samples, which, says the company, were impossible to produce using available WHOLEGARMENT technology.

The one-piece dress below can be knit with an asymmetrical silhouette without any loss of productivity through the use of variable stitch density.

This next pullover features unique dimensional stitches made possible with Shima Seiki's new movable sinker system

Thirdly, this punch lace garment is made possible through the use of a specialised cam system. The delicate design is suitable for proposals for the spring summer season

"As you can see, SWG-XR allows efficient production, brand new designs that promise to lead the way for knit fashion," Shima Seiki says adding that the company has backed up the investments in WHOLEGARMENT technology with more than 2,700 WHOLEGARMENT registered patents that incudes stitch structures and knit techniques.

Automation

At the show Shima Seiki is also focusing on its latest developments aimed at improving knitting mill automation through Industry 4.0 and Digital Transformation (DX).

Mills can begin by creating a production plan using Shima Seiki's knit production management system with which you can visually confirm job information and production plans for each machine.

Next, knitting data is sent automatically to the knitting machine according to the production plan. This saves time on operators otherwise programming each machine.

During production, yarn cone holders that feature censors for remaining yarn allow smooth replenishment of yarn whilst reducing down time.

Shima Seiki also proposes various solution in factory automation in cooperation with partner companies. The hanger system, for example, allows efficient factory management by using it for mobilizing yarn as well as for complete garments. "We also support factory automation with semi automatic steam setting and folding, bagging and sealing. All of these production processes can be monitored in real time from your PC or smart device.

"By making factory operations visually transparent, smooth communication can be realized for increased productivity."

On the large video screen at the booth, Shima Seiki is also introducing two prototype machines including a shaping machine and a new intarsia model. More information to follow on these new developments.

Here’s Everything About a Pipe Support and Their Functioning

Pipe support is used to assist a pipe for it to carry loads without any hassle. Such a support not only carries the load of the pipe but also the load transferred within it along with the weight of the pipe fittings. Many a time insulated supports also used can resist high or low temperatures. They are also made using corrosion and rust resistant standard.

Presently, there are 3 types of pipe supports:

Spring Support

Spring support is not only used with pipes but also assists columns, reservoirs, and vessels that can move caused by thermal expansion. They usually contain a coiled spring that takes the load of the expanded object caused due to enlargement.

Spring supports are further classified into 2 types: Constant Spring Hanger and Variable Spring Hanger. While in constant spring hangers, the load remains consistent; with variable soring hanger, the load is variable and only caters to vertical movements.

Rigid Support

Rigid supports restricts the movement of pipes in at least one direction. These supports are further classified into the following types:

Shoe Type -

A shoe type rigid support, fixed on the ground just makes the pipe rest on it.

Rigid Struts -

Rigid Struts used for its tension and compression abilities usually connect between a pipe and a supporting structure.

Rod Hangers -

A rod hanger only provides sport from the above only.

Shock Absorber

A shock absorber or a mechanical snubber provides applications to protect pipes from excess shock or tremors caused by earthquakes or any other force.

These are a few types of support for pipes that calmly provide their services without coming into anybody’s notice.

Functions and Applications of Spring Hanger

In order to satisfy the design criteria of power and process piping in industrial plants, spring hangers and supports are used. They are actually simple assemblies but engineers still have to understand why they are required in piping. Hence, we are going to discuss the functions and applications of a spring hanger to help you better understand its purpose.

Functions of a spring hanger

Spring hangers are most often considered as a special type of pipe support with spring in its assembly. What makes it different from other types of support is its spring rate or its lower stiffness. With this property, the spring hanger is capable of accommodating the displacement of the pipes while still providing the needed reaction force to support the piping. To achieve the right design of a spring hanger, especially its load and travel capacity, computational piping stress analysis is necessary. According to the pipe displacement principle, a spring hanger is capable of providing more stable and flexible support forces to piping when the springs are extended or compressed.

In terms of types, spring hangers are categorized based on load types - constant and variable. Constant spring hangers are designed with lever assembly which reduces the load variation of up to 6% maximum. Conversely, variable hangers are smaller and are more economical than constant spring hangers with the same capacity. With their flexibility, a spring hanger is used in many applications. These include the following:

In-line shell and tube heat exchangers or re-boilers

Lines that are connected to fired heaters and other high temperature air-cooled heat exchangers

Lines that are connected to storage tanks often under high differential settlement

Lines in power expanders and gas compressors

Lines in coke drums, reactors, and LNG separators

Ultimately, whenever the design that requires high support from spring hangers is ignored, it can lead to serious problems such as piping failure because of inappropriate load distribution. Other issues like leakage, pipe stress, and excessive vibration are also evident. This is why spring hangers play a vital role as piping support.

Basic Pipe Stress Concepts and Piping Loading Categories;

Piping systems experience different loadings, categorized into three basic loading types, namely Sustained, Thermal and Occasional loads. Sustained Load: It mainly consists of internal pressure and dead-weight. Dead-weight is from weight of pipes, fittings, components such as valves, operating fluid, test fluid, insulation, cladding, lining etc. Internal design/operating pressure develops uniform circumferential stresses in the pipe wall, based on which pipe wall thickness is determined during the process/P&ID stage of plant design such that "failure by rupture" is avoided. In addition, internal pressure develops axial stresses in the pipe wall. These axial pressure stresses vary only with pressure, pipe diameter and wall thickness, all three of which are pre-set at the P&ID stage and hence these axial pressure stresses cannot be reduced by changing the piping layout or the support scheme. On the other hand, dead-weight causes the pipe to bend (generally downward) between supports and nozzles, producing axial stresses in the pipe wall (also called "bending stresses"); these bending stresses linearly vary across the pipe cross-section, being tensile at either the top or bottom surface and compressive at the other surface. If the piping system is not supported in the vertical direction (i.e., in the gravity direction) excepting at equipment nozzles, bending of the pipe due to dead-weight may develop excessive stresses in the pipe and impose large loads on equipment nozzles, thereby increasing the susceptibility to "failure by collapse". Various international piping codes impose limits, also called "allowable stresses for sustained loads", on these axial stresses generated by dead-weight and pressure in order to avoid "failure by collapse". For the calculated axial stresses to be below such allowable stresses for sustained loads, it may be necessary to support the piping system vertically. Typical vertical supports to carry dead-weight are:

Resting steel supports,

Rod hangers,

Variable spring hangers, and

Constant support hangers.

Both rod hangers and resting steel supports fully restrain downward pipe movement but permit pipe to lift up at such supports. If pipe lifts up at any of the rod hangers / resting supports during operating condition, then that support does not carry any pipe weight and hence will not serve its purpose. Two examples are presented to illustrate how piping can be supported by spring hangers and resting steel supports to comply with the code requirements for sustained loads. Thermal Load (also referred as Expansion Load): It refers to the "cyclic" thermal expansion/contraction of piping as the system goes from one thermal state to another thermal state (for example, from "shut-down" to "normal operations" and then back to "shut-down"). If the piping system is not restrained in the thermal growth/contraction directions (for example, in the axial direction of a straight pipe), then for such cyclic thermal load, the pipe expands/contracts freely; in this case, no internal forces, moments and resulting stresses and strains are generated in the piping. On the other hand, if the pipe is "restrained" in the directions it wants to thermally deform (such as at equipment nozzles and pipe supports), such constraint on free thermal deformation generates cyclic thermal stresses and strains throughout the system as the system goes from one thermal state to another. When such calculated thermal stress ranges exceed the "allowable thermal stress range" specified by various international piping codes, then the system is susceptible to "failure by fatigue". So, in order to avoid "fatigue failure" due to cyclic thermal loads, the piping system should be made flexible (and not stiff). This is normally accomplished as follows:

Introduce bends/elbows in the layout, as bends/ elbows "ovalize" when bent by end-moments, which increases piping flexibility.

Introduce as much "offsets" as possible between equipment nozzles (which are normally modeled as anchors in pipe stress analysis). For example, if two equipment nozzles (which are to be connected by a pipeline) are in line, then the straight pipe connecting these nozzles is "very stiff". On the other hand, if the two equipment are located with an "offset", then their nozzles will have to be connected by an "L-shaped" pipeline which includes a bend/elbow; such "L-shaped" pipeline is much more flexible than the straight pipeline mentioned above.

Introduce expansion loops (with each loop consisting of four bends/elbows) to absorb thermal growth/contraction.

Lastly, introduce expansion joints such as bellows, slip joints etc., if warranted. In addition to generating thermal stress ranges in the piping system, cyclic thermal loads impose loads on static and rotating equipment nozzles. By following one or more of the steps from (a) to (d) above and steps (e) and (f) listed below, such nozzle loads can be reduced.

Introduce "axial restraints" (which restrain pipe in its axial direction) at appropriate locations such that thermal growth/contraction is directed away from equipment nozzles, especially critical ones.

Introduce "intermediate anchors" (which restrain pipe movement in the three translational and three rotational directions) at appropriate locations such that thermal deformation is absorbed by regions (such as expansion loops) away from equipment nozzles.

A few example layouts are presented to illustrate how loops/offsets, axial restraints and intermediate anchors are used to reduce thermal stresses in piping (and resulting nozzle loads). Occasional Load: This type of load is imposed on piping by occasional events such as earthquake, wind etc. To protect piping from wind (which normally blows in horizontal plane), it is normal practice to attach "lateral supports" to piping systems. During an earthquake, the earth may also move vertically. To protect piping against both horizontal and vertical movement during earthquake, some of the resting supports may be made as "integral 2-way vertical and lateral restraints". Fortunately, to carry sustained loads, normally vertical supports (as those listed under the Section titled "Sustained Load" above) are required. To withstand static seismic 'g' loads, "integral 2-way vertical and lateral restraints" are required. Generally, some of the vertical weight supports can be modified as "integral 2-way vertical and lateral restraints". On the other hand, for thermal loads, zero supports give zero stresses. So, thermal stresses and equipment nozzle loads will normally decrease as the number of supports goes down. Axial restraints and intermediate anchors are recommended only to direct thermal growth away from equipment nozzles.
