API 650 cylindrical tanks weld size

According to the standard of head of API 650 cylindrical tanks, there should be no crack, delamination, inclusion and other defects on the groove surface, which is consistent with the steel plate standard. The API 650 cylindrical tanks head polishing can adopt different technology according to different requirements, including rough polishing, medium polishing and fine polishing. Only the materials used for the third type of pressure vessels must be retested, and the materials used for the first and second class pressure vessels are not generally re inspected.

API 650 petroleum storage tanks are used for API 650 cylindrical tanks storage. API 650 petroleum storage tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature). Welding API 650 cylindrical tanks certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For API 650 petroleum storage tanks, non-destructive inspections are required, but third-party inspections are not required.
