LNG tank manufacturer

Liquefied natural gas (LNG) storage tanks are specialized products for storing LNG. They are special equipment, Class III pressure vessels, and undergo rigorous manufacturing processes including flaw detection, hydrostatic and pneumatic pressure testing, on-site inspection by the technical supervision bureau, and issuance of a pressure vessel inspection certificate. External rust removal and painting are also part of the manufacturing process. LNG storage tanks undergo strict quality assessments regarding the materials, dimensions, weld quality, operational quality, installation quality, internal devices, and safety accessories of pressure-bearing components. Routine physical and chemical tests are conducted on the tank materials, such as mechanical properties and chemical composition. Welded joints, welds, tank heads, and the geometric positions of various pressure-bearing components are rigorously inspected using X-ray non-destructive testing and magnetic particle testing. The product's sealing performance, pressure resistance, and all technical indicators that could affect its safe operation are also tested.
