Pressure Vessels & Tank
Pressure vessels & tanks are designed to hold liquids, vapors, or gases at high pressures, usually above 15 PSIG. Examples of common Pressure vessels & tanks used in the petroleum refining and chemical processing industries include, but are not limited to, storage tanks, boilers, and heat exchangers. Each vessel has its operating limits built-in by design that it must work under, referred to as its design pressure and design temperature. Operating outside of these limits could damage the equipment and potentially lead to loss of containment or catastrophic failure.
Because they work under immense pressure, a ruptured pressure vessel can be incredibly dangerous, leading to poison gas leaks, fires, and even explosions. For this reason, pressure vessel safety is imperative. Some several standards and practices cover the construction, maintenance, and inspection of pressure vessels—chief among these standards. Generally, a pressure vessel is a storage tank or vessel that has been designed to operate. Recent examinations of Pressure vessels & tanks have shown that there are many cracked and damaged vessels in workplaces. Cracked and damaged vessels can result in leakage or rupture failures. Potential health and safety hazards of leaking vessels include poisonings, suffocations, fires, and explosion hazards. Rupture failures can be much more catastrophic and can cause considerable damage to life and property. Therefore, the safe design, installation, operation, and maintenance of pressure vessels following the appropriate codes and standards are essential to worker safety and health.

A pressure vessel is a closed container designed to hold gases or liquids at a substantially higher or lower pressure than the ambient pressure that can be hazardous. A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially higher or lower than the ambient pressure. Examples include glassware, autoclaves, compressed gas cylinders, compressors (including refrigeration), vacuum chambers, and custom-designed laboratory vessels.
The majority of Pressure vessels & tanks are for industrial use. Some private-sector uses include hot water storage tanks and diving cylinders. Industrial uses for pressure vessels include distillation towers, hydraulic reservoirs, and containment of liquefied gases. Industrially, pressure vessels can be used for high-pressure or low-pressure containment, depending on the need of the client and the materials used. They can also be used for both cooling and process heating. As well as a means of achieving secondary containment in processing materials. For use with either gases or liquids, pressure vessels can be used in tandem with electric immersion heaters. Industrial versions of these heaters achieve the heating of various substances (water, oils, gases, and solvents) through direct contact. Immersion heaters can be mounted on a pressure vessel through flanged, welded, or threaded connections. The combination of electric immersion heaters and pressure vessels is ideal for heating gases and liquids and generating steam.
Most Pressure vessels & tanks, both for private and industrial uses, use various types of steel – particularly carbon steel and stainless steel. Individual steel parts are welded together to make pressure vessel cylinders or spheres. To avoid mechanical compromise through the welding process, particular precautions are taken to determine the properties of the steel used in the forged parts. These precautions ensure the mechanical strength of the materials and the soundness of the finished pressure vessel. For example, engineering standards currently require only steel with high impact resistance for use in fabricating pressure vessels. For some applications of pressure vessels made from steel, engineering standards also dictate unique corrosion-resistant material.
Pressure vessels & tanks are also fabricated using a partially load-bearing liner made from metal, ceramic, or a polymer. This liner helps to bear the internal pressure load, protects the vessel from the contained substance, and protects against leaking. Pressure vessels must follow strict manufacturing standards for fabrication.
