What is a

Pressure Vessel Welding

Pressure vessels are designed to store its contents under a specific amount of pressure, usually much higher than the atmospheric pressure outside. Because petrochemicals and other types of combustible – and potentially explosive – materials are usually kept inside them, pressure vessel welding has to abide by strict guidelines and regulations to ensure the safety of the people working on and around them. As such, it is not recommended to hire just any welding company to build them. They must be qualified for the high level of detail that pressure vessels must be built with.

Used of Pressure Vessel

Pressure vessels are found in many different industries, usually those involved with processing and manufacturing chemicals, food products, oil and gas. They can also be found outside of factories and processing plants albeit in a much smaller and portable form – propane tanks make for a good example. The following are the common uses of pressure vessels:

Processing Vessel

The word processing vessel is an umbrella term that refers to pressure vessels that facilitate various procedures such as mixing, distilling, chemical reactions, and general material processing. In order to perform these procedures, the pressure vessel must also be fitted with additional components.

Heat Exchange

Many pressure vessels can regulate their internal temperature, allowing heat to transfer over from one process to another. These vessels are sometimes referred to as heat exchangers, and are often found in food processing and pharmaceutical plants.

Storage

Certain types of petrochemicals that are used for various industrial purposes need to be stored in enclosed pressurized tanks because they may react violently when exposed to the pressure and elements found in the surface atmosphere. They are also used to control the water pressure in residential buildings so as to prevent the force of water from damaging faucets and shower heads.

Boilers

This type of pressure vessel is used primarily to bring liquids like water to boil so the steam can be used for processes like energy generation. Boilers have to be designed to withstand extreme temperatures and force produced by these processes. Because changes in pressure affects the boiling point of liquids, boilers can also be used to vaporize liquids much faster than heat alone.

Chemical Reactors

Chemical reactions can be violent and usually release large amounts of heat into their surroundings. For this reason, they are usually enclosed within pressure vessels designed to withstand high amounts of force and temperature that these processes produce. On the other end of the spectrum, pressure vessels can also introduce heat into a chemical reaction and create an environment that is most suitable for the chemical reaction to occur.

Shape

Pressure vessels come in two main shapes: spherical and cylindrical. Spherical pressure vessels can withstand incredible amounts of pressure due to their shape, which allows force to be evenly distributed across the entire vessel. Cylindrical pressure vessels are weaker in comparison because they have corners where stress can be concentrated on. Still, they are more than sufficient for the common purposes of a pressure vessel. They can also be made with three different types of “heads” that can improve the resistance of the vessel.

Material

Stainless steel, carbon steel, and aluminum are all common metals used in building pressure vessels. They have three things in common that are important for pressure vessels: strength, corrosion-resistance, and heat resistance. Both stainless steel and aluminum are easy to bend and weld whereas carbon steel is an exceptionally strong alloy. Titanium is also used in some instances for extreme conditions.

Questions And Answers

TIG welding and plasma welding are great welding techniques for pressure vessel welding, the former especially because it gives the welder better control of their work. Precision is key in pressure vessel welding.

A vessel welder is a metal fabricator that specializes in building pressure vessels. They must be very precise with their work to ensure that the vessel meets safety standards while also following specific requests by their clients.

Pressure vessel fabrication is the careful process of building pressure vessels to be used for industrial purposes. It involves cutting, bending, shaping, and welding metals like stainless steel and carbon steel into a finished vessel ready to be used.

The common applications of pressure vessels include boilers, pressurized storage tanks, heat exchangers, processing vessels, and chemical reactors.
