Preparations before storage tank inspection

Higher safety due to lower storage pressure.The technology is maturing and the storage tank equipment is shifting towards large-scale.

Underground storage tanks are usually designed in a cylindrical or oval shape

Purpose of risk assessment: Liquefied petroleum gas is a combustible, gasifying, thermal expansion, trapping, electrifying, corrosive, asphyxiant and toxic medium liquid petroleum mixed with air.

The hemispherical ends of the tanks are first formed by molding steel disks into shape in a 500-ton special press. A competent worker does this by handling the sheets, running the press, and verifying that each piece has been pressed accurately.

The tank area is poorly protected against flammable gases and cannot be detected in time. If an ignition source is found, it may cause fire or explosion.Container explosion Ambient temperature rises in summer.

LPG storage tanks are special containers for storing liquefied petroleum gas (LPG).

The LPG storage tank inspection schedule is as follows. When to inspect LPG storage tanks: at least once a year. The internal and external audit periods are divided as follows: At least every 6 years for security levels 1-3. At least every three years for Security Status Levels 3-
