API standard 650 stainless and carbon steel tank recommendation

Our company is a specialized technical support and after-sales service organization - customer service center. At the same time, we have provided excellent technical API standard 650 stainless and carbon steel tank personnel and strong technical support for our company, and cultivated an excellent after-sales team for our company. Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and API standard 650 stainless and carbon steel tank after-sales service of the project.

The cone slope of the completed API standard 650 stainless and carbon steel 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 API standard 650 stainless and carbon steel tank should have at least 4 detection tubes.

Allowable Design Stresses
The maximum allowable design stresses for the API standard 650 stainless and carbon steel tank materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.
