Definition - What does Pressure Vessel mean?
A pressure vessel is any structure such as pipes, barrels, bottles or any walled container that is capable of holding pressure.
Examples of pressure vessels include pipes that contain pressure in an aqueduct system. Airplane cabins are also common examples of structures that contain pressure. In industry, proper design of pressure vessels is important to prevent crack growth brought about by improper design and pressurization.
Corrosionpedia explains Pressure Vessel
Pressure vessels are containers or walled structures that can hold a certain amount of pressure according to the system it is used for. However, pressure is among the factors that should be monitored for corrosion prevention or control.
Stress corrosion cracking is a problem that design engineers must take into account when choosing materials, especially in the case of pressure vessels. The existence of internal stress must always be taken into consideration when implementing the degree of external applied stress where a certain equipment or vessel can be subjected in a safe manner.
Stress corrosion cracking in the case of pressure vessels can be particular to both the environment and the metal or material used in the pressure vessels. In specific environments, the existence of tensile stress may result in metal cracking.
Therefore, industries that make use of pressure vessels for their operations should be able to identify the means of deformation and stresses in pressure vessels in order to achieve a design that can prevent corrosion and failure.
