5652 aluminum tube API standard 650 mechanically-anchored flat-bottom tanks

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 standard 650 mechanically-anchored flat-bottom tanks and steel structures. At the same time, it also adheres to international standards and adheres to the international line.The API 620 large storage tank nozzle neck is fabricated by welding from 1/2-in. plate. The materials in the tank wall, the nozzle neck, and the reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank wall are fully radiographed, double-welded butt joints. The longitudinal joint in the nozzle neck is of the same type API standard 650 mechanically-anchored flat-bottom tanks but is not radiographed; however, the longitudinal joint and all other parts of the nozzle-and-wall-plate assembly have been shop stress relieved after fabrication, as required by 5.25. The adequacy of the reinforcement and attachment welds shown in Figure F-6 shall be determined.Before pressure testing, thoroughly flush the API 650 tank floating roof primary drain hose system. Supply API standard 650 mechanically-anchored flat-bottom tanks blind flanges, gaskets, and bolting (for other types of blanking covers as may be required) necessary for testing.Management concept: abide by laws, regulations and social norms. To improve the system of management, to carry out activities with high corporate ethics. Mutual respect, unity and harmony, create a "fair, just and open" good working environment for employees. Forge ahead, constantly pursue new technology innovation, create social value, and become a sustainable growth enterprise.Strictly control the welding groove forming of API standard 650 mechanically-anchored flat-bottom tanks: in order to ensure the geometric dimension of assembly and good welding of welding seam, before hoisting and laying, the edge of all metal vertical storage tank plate shall be polished by grinder, and the flatness of plate shall be ensured according to the design requirements. Strictly control the size of API standard 650 mechanically-anchored flat-bottom tanks weld assembly: measures must be taken to strictly control the assembly size of metal vertical tank bottom plate during assembly.
