· Pressure vessels are leak-proof containers that store liquid or gas. Pressure vessels of various sizes and shapes have been produced for different purposes. Generally, preferred geometries are spherical, conical, and cylindrical. A typical model is the combination of a long cylinder with two heads. Pressure vessels work at internal pressures higher or lower than air pressure. Besides, the operating temperatures of these systems differentiate
· Pressure vessels are designed to work by reaching the level of pressure required to make an application function, like holding air in a scuba tank. They can deliver pressure either directly through valves and release gauges, or indirectly via heat transfer. Potential pressure levels range from 15 psi up to around 150,000 psi, while temperatures are often above 400°C (750°F). A pressure tank can hold anywhere from 75 liters (20 gallons) to several thousand liters
· In the Oil and Gas industry, a pressure vessel is often used as a receiver where physical and chemical processes take place at high temperatures and pressures. Although the columns are used for different purposes, they are similar in construction. Distillation columns are used to divide feed streams or streams into multiple sources, based on feed part boiling points. In general, pressure vessels and columns are purchased from the same manufacturers because of their similar construction process.
· Carbon steel and stainless steel are the two most commonly used materials for construction in the oil & gas industry. A pressure vessel also requires other components in addition to the external body to become usable, such as vessel internals, distillation trays. Such components are highly complex and they require specifications that are very different from those necessary for the manufacture of pressure vessels that are supplied by specialist suppliersAmbit Automation – Kerala’s No.1 Short Term, Job Oriented Training InstituteAmbit Automation – Kerala’s No.1 Short Term, Job Oriented Training Institute
