floating roof tank insert style shell openings
API 650 petroleum storage tanks are used for floating roof tank storage. API 650 petroleum storage tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature). Welding floating roof 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.
The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, floating roof tank and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.
The cone slope of the completed floating roof tank foundation is 15/1000 for the general foundation and less than 35/1000 for the soft foundation. After the foundation settlement of the storage tank is basically stable, the surface slope must be greater than eight thousandths. The edge of the tank bottom should be more than 0.3 meters higher than the surrounding ground. Above the ground, the tank bottom leakage detection tube should be drawn from the foundation sand cushion and cross the foundation ring wall or the slope protection surface. The circumferential distance should be less than 20 meters, and each floating roof tank should have at least 4 detection tubes.
