Cracking of the weld seams on the outer wall of the acidic water tank in acid gas treatment units for petrochemical environmental protection
Thread Content
The image below shows cracks in the weld seams on the outer wall of the acidic water tank, which is part of the acidic water gas treatment equipment used in the petrochemical industry. The acidic water contained in this tank can cause stress corrosion cracking in the weld seams as well as in the heat-affected zones of the tank’s inner wall metal, making it quite difficult to resolve this issue.
The cracking of the weld seams on the outer wall of the acidic water tank is likely caused by stress corrosion. This phenomenon is quite common in the petrochemical industry; to address it, effective anti-corrosion measures must be taken, along with regular inspections and maintenance. .
