Suitable procedures must be established and maintained for identifying the material making up the components of the equipment which contribute to pressure resistance by suitable means from receipt, through production, up to the final test of the manufactured pressure equipment.

In order to enable the equipment to carry out normal operation, testing, and maintenance, the shell and head of the pressure vessel must generally have holes. Such as material import and export; connection holes for measuring pressure, temperature and installation of safety devices; liquid level gauge holes, manholes and hand holes, etc.

Pressure vessel design is based on given working conditions and process dimensions, considering the requirements of manufacturing, installation and maintenance, and load analysis and stress analysis on the correct selection of materials for each component of the pressure vessel.

Any equipment has a designed service life, and pressure vessels are no exception, but how many years is this service life? 8 years, 10 years, 15 years, or even longer? Today we will talk about this issue in detail.

Gas storage tanks can be divided into many types according to different pressures, including low pressure, medium pressure, high pressure, negative pressure and so on. There is no direct connection between the gas volume and air pressure of the gas storage tank, but the two complement each other.
