ASTM A27 grade 60-30 floating roofs API Std 650 welded steel storage tanks

API 650 petroleum storage tanks are used for API Std 650 welded steel storage 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 Std 650 welded steel storage 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.

The specifications used in the design of large oil tanks, API Std 650 welded steel storage tanks mainly include American Petroleum Institute Standard API 650, Japanese Industrial Standard JIS B8501, British Industrial Standard BS2654 and Chinese National Standard GB50341 from a global perspective. The formulas used in each specification are based on the hoop stress in the membrane theory. Each specification is based on the performance characteristics of materials and the construction technology level of their respective countries to determine the allowable stresses and weld coefficients. Therefore, the calculation results of tank wall thickness of API Std 650 welded steel storage tanks with the same volume are sometimes quite different according to different specifications.

Suggested Practice Regarding Installation of Low-pressure Storage Tanks
Access: All openings and accessories for tanks API Std 650 welded steel storage tanks constructed according to this standard shall be installed so that any periodic inspections required can be readily made.
Corrosion: When a tank bottom rests directly on the ground, a survey shall be made to establish the need for cathodic protection.
Drainage: All tanks in which water might accumulate under the hydrocarbon contents shall be provided with adequate drains that are suitably protected from freezing.
