stress corrosion cracks
The difference between LPG storage tanks and general storage tanks is that the medium, due to the presence of wet hydrogen sulphide.
The difference between LPG storage tanks and general storage tanks is that the medium, due to the presence of wet hydrogen sulphide, will produce stress corrosion tendency and may lead to cracking, in addition, it may also produce oxygen bulging package, hydrogen bulging bubbles and other defects caused by hydrogen damage.
For stress corrosion cracks, as this is the result of tensile stress conditions of materials and media matching, is a dangerous form of damage, the final form of destruction for brittle fracture, is a dangerous failure factor of the liquefied petroleum gas storage tanks, can be judged from three aspects of the existence of stress corrosion tendency.
