API Std 650 horizontal tank drain pipe

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, API Std 650 horizontal tank and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

The foundation design of the API Std 650 horizontal tank should meet the requirements of foundation stability and deformation, that is, the API Std 650 horizontal tank foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the API Std 650 horizontal tank and cause distortion and deformation of the tank wall and bottom plate.

Allowable Design Stresses
The maximum allowable design stresses for the API Std 650 horizontal 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.
