API standard 650 welded aluminum storage tanks butt-welded bottom joints

Allowable Design Stresses
The maximum allowable design stresses for the API standard 650 welded aluminum storage tanks 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.This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API standard 650 welded aluminum storage tanks design, supply, fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached Datasheets and/or Drawings.our company offered 2950 ton A36 steel API standard 650 welded aluminum storage tanks 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.The finned tube heating device for high temperature heat transfer oil for large API standard 650 welded aluminum storage tanks has the advantages of convenient inspection and maintenance. The high-efficiency fin heating coil assembly is composed of spirally arranged finned coils. The fins are mainly arranged in the straight pipe section, and the whole assembly is supported by several angle steel supports. The high-efficiency fin heating coil component can enter and exit from the manhole of the API standard 650 welded aluminum storage tanks, which is convenient for maintenance and repair.The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
