How to Use Oxy Fuel - Oxygen Acetylene - Cutting Torch Equipment Safely

An oxygen acetylene torch flame is around 6000 degrees F. Considering Steel melts at around 2800F that is pretty freakin hot!

You can make a lot of things happen with an oxygen acetylene torch kit. You can braze air conditioning line sets, solder copper water pipe, silver braze stainless steel, weld 4130 chromoly tubing, and even heat and bend metal thicker than 1 inch. But oxy-fuel torches can be extremely dangerous if not used properly. OSHA even requires employers to ensure workers that use oxyfuel equipment to be properly trained and qualified for oxy-fuel welding, cutting, heating, and brazing. (see 29 CFR 1910.252)

From my 30 plus years in the welding field, I am constantly surprised by the lack of training in the safe operation of oxyfuel equipment.. Even seasoned welders are often deficient in use of here acetylene torches unless they have received hands-on training where demonstration of proficiency was required

Safe operation of oxygen acetylene equipment requires training, willingness to follow basic safety guidelines, and understanding some basic safety principles:

o Oxygen cylinders are pressurized to over 2500 psi and can become a projectile if knocked over. Always , always, always keep the cap screwed on when the cylinder is not secured.

o Acetylene cylinders are filled with acetylene gas compressed into a porous substance saturated with liquid acetone. They should remain upright to prevent liquid acetone from damaging the regulators and restricting gas flow. If you have to lay them down to haul them, let them stand upright for a while before using.

o Never transport or store cylinders in an enclosed space (i,e, trunk of car, or truck tool box) Welding supply stores often display pictures of cars demolished by the explosion of oxygen and acetylene cylinders hauled in the trunk of a car. They even make you sign a waiver if you want to haul cylinders yourself.

o Never use damaged equipment.

o Always open oxygen cylinders very slowly. Opening them quickly is very dangerous and can cause the regulator to explode. Yes I said explode. (if you don't believe me, just Google "regulator burnout")

o Use check valves or combination check valve/flashback arrestors to prevent reverse flow of gases and to prevent mixing of gases.

o Never use oil on any part of the equipment. Oil in the presence of pure oxygen can ignite easily

o Always bleed down the gases and back out the regulator screws when finished using the torch

There are several different manufacturers of oxyfuel equipment: Victor, Smith, and Harris are 3 of the main brands and each designs their equipment differently with certain features in mind. So the operation of each manufacturer's torches is different. Always follow the manufacturer's instructions.

The first thing to do when preparing to operate a oxyfuel torch is to inspect the equipment. Make sure the cylinders are fastened securely to prevent them from falling over.. Next, inspect the hoses to make sure they are not cracked or dry rotted. Feel the brass connectors to make sure they are all tight and ensure the cylinders valves are closed with the regulators reading zero.

If the regulators are not reading zero, one of two things is wrong: The gauge or gauges have been damaged or the previous user failed to bleed the pressure from the line. To release the pressure , open the appropriate valve on the torch and turn the regulator screw clockwise until the needle moves to zero. If the needle does not go to zero, the gauge is damaged and must not be used.

If the gauges are determined to be operating properly the next thing to do is make sure the regulator screws are backed out where you cannot feel spring pressure on them.

Here is a simple ABC, 123 checklist to use for setup and shutdown of oxy-fuel equipment.

o Wear proper Personal protective equipment i.e. shade 3 to 5 ANSI eyewear, gloves etc.

o Inspect the equipment for : Overall condition of hoses, zeroed gauges, check valves, torch, chains on bottles

o If gauges are not reading zero, purge lines to let gauges zero out

o If gauges are damaged replace them

o Open oxygen cylinder valves very slowly. (This is the most important step on this page)

o Select proper tip according to manufacturers guidelines

o Use manufacturers tip chart to determine pressure settings

o Set gauges

o Purge lines individually

o open acetylene torch valve to ¼ turn and Light torch

o Increase acetylene flame high enough to where soot disappears.

o Add oxygen to flame until blue cones define creating a neutral flame.

o Perform work

o Extinguish flame by turning off gas valves on torch (manufacturers differ on whether to turn off acetylene or oxygen first.)

o Turn off cylinders

o Purge lines

o Once gauges are zeroed, back out regulator screws

o Return torch to storage place

o Secure oxy-fuel equipment for next user

How Oxygen and Nitrogen generators are used in manufacturing companies

The air we breathe contains two gases that are extremely useful in industry: oxygen (about 21%) and nitrogen (about 78%). Adding oxygen to a process enables better control of heating patterns, higher furnace efficiencies (for lower fuel consumption) and reduction in particulate and NOx emissions. It’s used with fuel gases to enhance processes including gas welding, gas cutting, oxygen scarfing, flame cleaning, flame hardening and flame straightening. Oxygen is a raw material in many oxidation processes and to regenerates catalysts. Nitrogen gas is used for purposes ranging from inerting and purging to flushing and sterilizing to product transfer and packaging. Many such processes remove undesirable oxygen from a manufacturing process or environment, preventing oxidation that can damage metal parts and sensitive electronics. Nitrogen is also used in refining and gas separation processes. Since oxygen and nitrogen occur together in the air, they must be separated before they can be used. The right tool for the job is an oxygen generator or a nitrogen generator.

How an Oxygen plant works

Oxygen molecules are separated from the other molecules within a clean, dry compressed air stream. Pressure Swing Adsorption (PSA) is a simple, reliable and cost-effective technology that enables continuous, high-capacity oxygen flow at the desired level of purity (90% to 95%). Adsorption happens when atoms, ions or molecules from a substance (compressed air in this case) adhere to a surface of an adsorbent. PSA technology isolates oxygen molecules from other molecules (nitrogen, CO2, water vapor and trace gases) to leave high purity oxygen at the outlet of the generator. The process takes place in two separate pressure vessels (tower A and tower B), each filled with a carbon molecular sieve, that switch between a separation process and a regeneration process.

How a Nitrogen generator works

Nitrogen molecules are separated from other molecules within a clean, dry compressed air stream. Pressure Swing Adsorption technology is used here as well, to isolate nitrogen molecules from other molecules in compressed air to leave nitrogen at the desired purity at the outlet of the Nitrogen plant. For some applications, such as tire inflation and fire prevention, relatively low purity levels (between 90% and 97%) are required. Other applications, such as food/beverage processing and plastic molding, require higher levels of purity (from 97% to 99.999%).

RO and DI filters use different physical reactions to clean water. Reverse Osmosis (RO) is used to partially clean-up tap water to make it roughly 90% to 99% pure. Deionization (DI) filters exchange positive hydrogen and negative hydroxyl molecules for positive and negative contaminant molecules in water. DI filtering and other processes are sometimes referred to as "water polishing."

Understanding the difference between reverse osmosis (RO) and deionized (DI) is important when identifying the right water purification unit for your lab. Having access to high quality water is essential for laboratories to carry out their daily processes and workflows. By taking a closer look at different methods of producing both types of water, RO and DI, you can feel confident in your decision regarding water purification systems.

This deep cold air separation adopts molecular sieve purification and supercharged turbo expander to supplement the cooling capacity of the device, and at the same time adopts the process of producing argon without hydrogen through full distillation. This process is safe, reliable, and economical. The main reasons are:

1. Good safety The whole set of equipment has low operating pressure, simple process, high equipment safety, long switching cycle of molecular sieve system, long service life of switching valve, and reduced safety hazards. The main cooling (K1) adopts 1% liquid oxygen emission to ensure that the accumulation of hydrocarbons is minimized.

2. High reliability A large amount of surplus nitrogen can be sent to the water cooling tower, reducing the load of the chiller, reducing the energy consumption of the air separation unit, reducing the use cost, and further improving the reliability of the device.

3. Convenient operation and maintenance, simple process

Regenerative desiccant dryers are used in compressed air systems that require dew points to be below the minimum that refrigerated dryers can produce (generally 40 degrees Fahrenheit). Three types of regenerative desiccant dryers are widely used throughout industry: heatless, heated and blower purge.

The following discussion doesn’t address heat-of-compression (HOC) desiccant dryers, even though they require the least amount of energy to operate. The use of HOC dryers is limited to lubricant-free compressors.

Many plants require air quality that only regenerative desiccant dryers can produce. Unfortunately, in too many cases, the decision about which type of regenerative dryer to purchase is based on initial capital cost alone. This decision basis ignores the cost of energy that will be required to operate the dryer. Including energy cost can alter the economics of a purchase decision dramatically.

Some of the first known filters were created to remove unwanted contaminants from water. This process was pioneered by the Romans, but it has also been cited as having other origins. The word "filter" actually comes from the Latin word "filtrum" or "feltrum," which is related to felt or compressed wool, providing a means to filter contaminants when water passes through it. The development of filters for oil cleanliness did not occur until the early 1900s through the progression of crude oil refining and the automobile industry.

Manufacturing and development of a bolted GFRP flange joint for oil and gas applications

The manufacturing industry saw a significant rebound, and oil prices started to recover as well. Both of these trends are expected to continue in 2017.

At Allied Valve, we also saw some big changes this year. We expanded our product line to include Masoneilan control valves, CDC rupture discs, and Groth relief valves and flame arresters. We also beefed up our service capabilities with a new Mobile Lab trailer and new control valve testing systems.

Finally, we continued our initiative to bring you valuable content related to valves, actuators, and the many industries we serve. Here are our top 5 industrial valve articles of 2016.

Maximizing Your Control Valve Performance: A Guide to Control Valve Selection, Maintenance, and Repair

Process plants can contain thousands of control valves, responsible for keeping process variables like flow, level, pressure, and temperature within the desired operating range. Despite their importance to product quality, efficiency, and a company’s bottom line, control valves are often neglected. This article provides an in-depth look at the factors that affect control valve performance and how to keep your valves always working their best.

It came to our attention earlier this year that some safety valves containing Thermodiscs (e.g., Consolidated 1811 and Consolidated 1711 series) were being put through hydrostatic testing. These valve parts are designed for steam service only and water can cause damage, potentially beyond repair. This article describes the problems that hydrostatic testing can cause and what you can do to mitigate these problems.

The American National Standards Institute (ANSI) and the International Society of Automation (ISA) provide standards for the hydrostatic testing of control valves. The goal of the test is to verify the valves’ structural integrity and leak tightness. This article summarizes the fluid, pressure, and time requirements of hydrostatic testing as well as the standards for acceptable performance.

To work properly when they’re needed, all valves must be maintained. It used to be that preventative maintenance was the only option. But with the diagnostic tools available today, it’s possible in some cases to use a data-based predictive approach instead. Both of these approaches are part of an effective valve disc maintenance program. This article helps you understand when each of them is most appropriate.

Sand casting can be used for the majority of metals. Even highly reactive magnesium is sand cast provided care is taken and the correct materials used by adding what are called inhibitors into the sand.

Sand castings inevitably have a slow cooling rate because of the large insulating mass of sand surrounding the liquid metal as it cools. Grain sizes and dendrite arm spacings tend to be larger than in equivalent section sizes in die-castings.

Sand casting involves the pouring of molten metal into a cavity-shaped sand mould where it solidifies (Fig. 6.8). The mould is made of sand particles held together with an inorganic binding agent. After the metal has cooled to room temperature, the sand mould is broken open to remove the casting. The main advantage of sand casting is the low cost of the mould, which is a large expense with permanent mould casting methods. The process is suitable for low-volume production of castings with intricate shapes, although it does not permit close tolerances and the mechanical properties of the casting are relatively low owing to the coarse grain structure as a result of slow cooling rate.

The goal of this experimental study is to manufacture a bolted GFRP forged flange connection for composite pipes with high strength and performance. A mould was designed and manufactured, which ensures the quality of the composite materials and controls its surface grade. Based on the ASME Boiler and Pressure Vessel Code, Section X, this GFRP flange was fabricated using biaxial glass fibre braid and polyester resin in a vacuum infusion process. In addition, many experiments were carried out using another mould made of glass to solve process-related issues. Moreover, an investigation was conducted to compare the drilling of the GFRP flange using two types of tools; an Erbauer diamond tile drill bit and a Brad & Spur K10 drill. Six GFRP flanges were manufactured to reach the final product with acceptable quality and performance. The flange was adhesively bonded to a composite pipe after chamfering the end of the pipe. Another type of commercially-available composite flange was used to close the other end of the pipe. Finally, blind flanges were used to close both ends, making the pressure vessel that will be tested under the range of the bolt load and internal pressure.

In manufacturing of the steel bridge, fillet welded T-joint is widely used and angular distortion is often generated. So, reduction or control of angular distortion without additional processes to welding is strongly demanded because it takes great time and effort to correct the angular distortion. In this study, the effectiveness of welding with trailing reverse-side flame line heating for preventing angular distortion was investigated through the welding experiment and numerical simulation in submerged arc welding of fillet T-joint with three different thick flange plate. First, the heat source models for numerical analysis of both submerged arc welding and flame line heating were constructed based on the comparison with the measured temperature histories and angular distortion. And then, these heat source models were used in combination with various kinds of distance between two heat sources to make clear the appropriate distance condition for smallest angular distortion was 150 mm, and it does not depend on thickness of flange plate. It was also confirmed that the experimental angular distortions were in good agreement with those calculated. With a focus on the influence of thickness of flange plate, the reduction of angular distortion by welding with trailing reverse-side flame line heating becomes smaller with increasing thickness of flange plate. However, angular distortion could be adequately prevented under the appropriate flame line heating condition in either thickness of flange plate because the welding-induced angular distortion also becomes smaller with increasing thickness of flange plate. Thus, it was concluded that welding with trailing reverse-side flame line heating could be useful for preventing angular distortion of fillet T-joint, which is a component of steel bridge, enough not to correct it after welding.

Garlock offers a range of Butterfly Valves for different applications. Ranging from GAR-SEAL Butterfly Valves are used extensively where corrosive, abrasive and toxic media, to STERILE-SEAL valves are used in applications where sterile processes need to be maintained in the pharmaceutical and food industries.

Depending on your application, different air valve material and design type should be used. For a better understanding on which type of Garlock Butterfly Valve will best fit the application, you can refer to our Chart

The mechanism of opening of the aortic valve was investigated in dogs by attaching radiopaque markers to the commissures and the leaflets. Analysis of abnormal cardiac cycles demonstrated that, when the ventricular pressure first equalled the aortic pressure, the intercommissural distances increased 9 percent, and the valve opened with a stellate orifice without forward flow and without a rise in aortic pressure. Further opening of the aortic valve was dependent on forward flow over a narrow range. A new mechanism of aortic valve opening is proposed. This mechanism results in minimal flexion stresses on the leaflets and is important for the longevity of the normal aortic valve. It can occur only if the leaflets arise from an expansile aortic root.

Features of titanium rod filters and regenerative applications

Titanium is considered to be a rare metal because it is dispersed and difficult to extract in nature. But it is relatively rich, ranking tenth among all elements. Titanium ore mainly consists of ilmenite and rutile, which are widely distributed in the earth's crust and lithosphere. Titanium also exists in almost all living things, rocks, water bodies and soils. The extraction of titanium from the main ore requires the use of the Kroll method or the Hunter method. The porous titanium rod filter element is the core component of the filter. The rod-shaped filter element is made of pure titanium metal powder after special molding process and sintered at a high temperature, and has a large number of fine pores with a controlled pore diameter penetrating inside. Titanium filter element filtration is a combination of surface filtration and depth filtration. When the solvent flows through the porous titanium rod filter element, the oxidized Fe ̈ and the solid suspended matter impurities in the solvent gradually form a filter cake layer on the surface of the filter element under the action of inertial collision and microporous retention of the titanium metal filter element, as the filtration proceeds. The filter cake layer gradually thickens and the filtration resistance also increases. When the maximum pressure of the pump is reached, the flow rate is stopped and the operation is stopped. Slowly backflush the residual liquid to the solvent tank with compressed air, then increase the pressure backflushing filter element, then pressurize the water with a pump and backwash it, discharge the impurities through the drain port, and complete the filter regeneration, that is, complete a filtration cycle. When running for a long time, the backflushing and backwashing effects are reduced, and when the filtration flow rate is small, the machine needs to be shut down, the flower basket combined filter cartridge group is taken out, and it is completely regenerated by chemical cleaning. The titanium rod filter has: (1) High filtration accuracy. The light red-yellow solvent (concentration of Fe is about l0~l5 g/L) can be filtered into a colorless and transparent liquid (the solid suspension and Fe ̈ are all filtered out, and the Fe concentration in the solvent is reduced to below 5 g/L). ). (2) Good acid and alkali resistance. It can be used for filtration of strong acids and bases and various organic solvents. (3) High mechanical strength. The micropores are used and cleaned without deformation, and the working pressure can reach 1.0 MPa. (4) Long service life. In general, it is used to filter out iron ions in the solvent. The titanium rod filter can be used for 3 to 5 years. (5) Convenient operation and sustainable operation. The complete regeneration of the filter element does not require the preparation of a special chemical cleaning solution, which can be solved by hot galvanizing on site. The hot-dip galvanizing solvent filters out iron ions for continuous filtration on-line or gap filtration. Before using the titanium rod filter, air tightness inspection should be carried out, pay attention to the sealing of the flower disc and the built-in liquid discharge pipeline in the contaminated area and the clean area; when backflushing and backwashing, the feed valve should be closed, and the filter material should be closed. After the liquid is emptied (can be assisted by backflushing air), then open the blowdown valve to increase the backflushing air pressure (backflushing pressure 0.4~0.6 MPa, time l0~20s), repeat several times, press the water with the pump, and reverse wash. The porous titanium rod filter is oxidized to Fe by oxidizing (potassium permanganate, potassium chlorate, hydrogen peroxide, etc.) to form a precipitate, and the content of Fe in the solvent can be reduced to 5 L or less by filtration through porous titanium metal. The suspended solids greatly reduce the amount of zinc slag and the rate of re-plating, and improve the quality and work efficiency of hot-dip galvanizing products.

Pointers to the Make Best Choice of Carbon Steel Fittings

If you are in the design phase of a new industrial project which includes pipe installation, you would want to make a decision on what kind of material should be used for laying down the pipes, elbows, flanges etc. In this context it would be useful to keep in mind a few of the following pointers:

• Evaluate the magnitude of the project • Understand the scale of the implementation • Enumerate the liquids or gases the pipes are going to carry • The desired age or longevity of the structure

These pointers help decide which metal to choose to lay down the pipes. Usually, steel is a popular choice, considering its characteristics. Additionally, in order to enhance the characteristics of steel, carbon or chrome too is used along with it. Thus, the carbon steel fittings become the perfect choice for industrial projects. The major benefits of using these carbon steel pipe fittings are:

1. Strength: Addition of carbon to steel in order to make carbon steel pipes lends more robustness to the product. More the carbon, more the durability. The carbon steel pipes when heated help improve the strength without losing the shape.

2. Adjusting Power: As you would know, the durability and strength of these pipes can be adjusted based on the amount of heat and carbon that is being used. This helps to achieve a perfect match for the required specifications. Hence, based on what the project is, the proportion of carbon to steel can be morphed.

3. Durability: These pipes which are carbon steel, survive environmental changes. They have a peculiarity of being rust resistant which in turn increases their longevity.

Keeping in mind these factors, whether these pipes are the stainless steel welded pipes or the carbon steel seamless pipes; no project is complete without them. In addition to these pipes,an important role is also played by the flanges.

There is a wide variety of flanges available in the market today. However, making the right choice of flange to the right project becomes critical. Understanding the project requirements, makes this choice simple. If the project demands high temperatures or sub zero temperatures or high pressure of gas or fluids, then the weld neck flanges are good choices. This flange with its tapered hub provides extra reinforcement, required in several applications. The flange fits perfectly into the internal diameter of the pipe and this helps to avoid all hitches in the flow of desired substances through the pipes. Erosion as well as any kind of turbulence at the joints is reduced.

Thus, having a good knowledge of both the kinds of pipes as well as flanges that suit the requirements of a particular project, help the person in charge to make a good choice. This choice is critical not just for the perfect implementation of the project but also for the durability, effectiveness and longevity of the implementation.

Additionally, using the right kind of pipes and flanges during project implementation helps the project to pass the quality, efficiency as well as safety parameters.
