Scope

Scope: This standard specifies the classification and designations, order content, dimensions, appearance, weight and allowable deviations, technical requirements, test methods, inspection rules, marking, packaging, and quality certificates for double-sided composite stainless steel pipes with seam welding. This standard applies to a wide range of industries, including machinery, construction, municipal engineering, shipbuilding, bridges, metallurgy, vehicles, railways, highways, aviation, containers, furniture, decoration, etc. This standard is suitable for structural applications of stainless steel double-sided composite pipes, and can also be used for general fluid transportation applications of stainless steel double-sided composite pipes. Main technical content: Stainless steel double-sided composite refers to a composite method in which the inner and outer layers of metal are stainless steel, and the middle layer is carbon steel or alloy steel. Through metallurgical rolling, the inner and outer layers of metal are fused at the bonding site. Stainless steel metallurgical composite plates not only have the corrosion resistance, heat resistance, and wear resistance of the cladding stainless steel material, but also have the strength and stiffness of the base material of carbon steel or alloy steel. Moreover, there is good shear strength at the junction of different metal layers. Therefore, stainless steel double-sided composite steel pipes, as a type of composite pipes, can fully utilize the mechanical properties of carbon steel and alloy steel base materials and the anti-corrosion (rust) performance of stainless steel cladding. Whether replacing stainless steel pipes or carbon steel pipes, they can reduce costs throughout their entire life cycle. Seam welding refers to the use of stainless steel double-sided composite coils as raw materials and the production of composite pipes by roll bending continuous forming and high-frequency welding. There are round pipes
