1060 aluminum shapes API Std 650 self-anchored tank

API 650 petroleum storage tanks are used for API Std 650 self-anchored tank storage. API 650 petroleum storage tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature). Welding API Std 650 self-anchored tank 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.

API Std 650 self-anchored tank weld tightness test: remove dirt from the API Std 650 self-anchored tank weld, apply white powder emulsion, spray kerosene on the other side of the weld after drying. Because of the strong penetration of kerosene, if kerosene is sprayed after 12 hours (under low temperature conditions, the time can be extended), if the surface of the welded seam coated with white emulsion has no spots, the welded seam meets the requirements.

In addition to the requirements of API Standard 620 tank Appendix Q.8.1, the nameplate shall be attached to the tank at an accessible location if it is outside of any insulation or protective covering of the tank. The nameplate for the inner tank shall be located on the outer tank wall but shall refer to the inner tank. The nameplate, if any, for the outer tank of a double-wall tank shall be located adjacent to the nameplate or the inner tank and shall refer to the outer tank.
