Shop assembly of API standard 650 low-alloy steel tanks

After the API standard 650 low-alloy steel tanks is manufactured, air tightness test and water filling test are carried out according to the design requirements, and the pipeline must be subjected to pressure test to fully meet the acceptance technical specifications. Improve the quality assurance system, adhere to the principle of who constructed is responsible for the quality of the project, conduct regular quality inspections, and immediately rectify any problems. Fill in the API standard 650 low-alloy steel tanks installation technical records in time to ensure the synchronization, integrity and reliability of the technical data.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 low-alloy steel 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 the start of erection, inspect each API 650 tank foundation to ensure that it is level and acceptable to receive Work. Remove temporary erection attachments welded to the interior or exterior of the API standard 650 low-alloy steel tanks shell or to the bottom by arc gouging, and grind weld area smooth.Advanced typical figures and typical deeds are the embodiment and symbol of API standard 650 low-alloy steel tanks enterprise spirit, outstanding ideas and vivid images, with strong demonstration, radiation and transmission effect. Without distinctive typical characters, there is no unique enterprise culture. In carrying out the construction of enterprise culture, the advanced enterprise culture should be typified. Vigorously excavate, discover, cultivate and summarize the company's API standard 650 low-alloy steel tanks advanced models.The company has accumulated rich experience in long-term cooperation with new and old customers, which makes our products API standard 650 low-alloy steel tanks more unique in the same industry, and is favored and praised by users. We always adhere to the enterprise spirit of "integrity, dedication, and people-oriented" and the business philosophy of "creating benefits for users".
