API standard 650 stainless and carbon steel tank heat-affected zone
Allowable Design StressesThe 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.
Selection of nominal diameter D of API 650 storage tank. In the design calculation of API 650 storage tank, the bottom plate thickness is the net plate thickness, that is, the actual thickness minus the corrosion allowance. In the design and calculation of API standard 650 stainless and carbon steel tank wall thickness in hydrostatic test, the thickness of bottom plate is the total thickness of steel plate.
our company offered 2950 ton A36 steel API standard 650 stainless and carbon steel tank plate to Philippines customer, which was used to build water supply project. It is the government project. The procurement with their project engineer come to China to discuss this project in middle of 2016. After checking the mill, they signed the contract with us. we supply the ASTM A36 Original Mill Test Certificate Stamped.
}Generally, the snow load in the API standard 650 stainless and carbon steel tank construction area should be considered before the design and construction of the tank. The snow load in the API standard 650 stainless and carbon steel tank construction area has an impact on the tank roof design and operation, especially in the area with large snow load, the roof load of large storage tank with large diameter increases. Anti freezing, heat preservation and waterproof measures shall be taken for the additional facilities of storage tanks, such as pumps, breathing valves, flame arresters, detection instruments and thermal insulation layers.
Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our API standard 650 stainless and carbon steel tank service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's API standard 650 stainless and carbon steel tank customer service to establish a good, comprehensive, full service system.
