API 650 insulated tanks welding requirements
This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API 650 insulated tanks storage of petroleum, petroleum products. and other liquid products.
Welding inspection of bottom plate of API 650 insulated tanks, vertical oil tank: During the fabrication and installation of API 650 insulated tanks, the bottom edge plate is welded first. According to the requirements of the technical standard, penetrant inspection is required for the weld of edge plate at the bottom of API 650 insulated tanks, that is, penetrant testing is required for each weld bead priming, filling and capping. In the process of testing, if any defect is found, it shall be repaired immediately. After the repair, the surface coloring penetrant test shall be conducted again until the test result is qualified.
When as-rolled plate material complies with impact test requirements as specified here, the material need not be normalized. If, as with ASTM A516, the specification prohibits impact test without normalizing but otherwise permits as-rolled plates, the API 620 welded storage tanks material may be ordered in accordance with the above provision and identified as “MOD” for this API modification.
