API standard 650 mechanically-anchored steel tanks metal-seated ball valve

Before welding the API standard 650 mechanically-anchored steel tanks, the professional skills of the welding personnel shall be fully assessed to ensure that the operators meet the corresponding welding qualifications. According to the technical standards, scientific and feasible process requirements are actually formulated. In the process of welding the edge plate of API standard 650 mechanically-anchored steel tanks, electric welding is required on one side of the edge plate, so that the edge plate has a free shrinkage effect and greatly reduces the residual stress of the welding seam.All API standard 650 mechanically-anchored steel tanks fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole, and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.Structural features of API 650 double-layer oil tank: steel glass fiber reinforced plastic double-layer structure, special processing method is adopted between the API standard 650 mechanically-anchored steel tanks internal steel shell and glass fiber reinforced plastic layer, so that a gap of 0.1 mm is created between the internal and external layers. Even if the API 650 oil storage tank leaks, it can ensure that the contained dangerous substances only flow in the gap, and will not immediately overflow the external environment.To the society: With the development of the company, BEBON has always adhered to the development mission of "developing heavy industry for the benefit of all mankind; improving the environment and achieving sustainable development”, operating with integrity and paying taxes in accordance with law.For our employees, the company fully respect employee value, pursuing mutual development of enterprise and employees.As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another API standard 650 mechanically-anchored steel tanks magnificent projects.
