GB/T5312-1999 (ships are made by seamless steel tube of carbon steel and carbon manganese steel). It is mainly used for Marine boiler and overheating is used the class I and class II pressure tubes, etc. Standard materials are steel grade 360, 410, 460, etc. 6. How is seamless tubing made?How is seamless tubing made?The seamless tube is manufactured using a process called extrusion. During this process a solid steel bar is pierced though the centre using a die, turning the solid round into a round tube.Difference between ERW, DOM and Seamless Tube Metal gb standard steel seamless round tube

NomenclatureConstructionAdvantagesOperationsProductsThe nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip is unwound from coils and side-trimmed to control width and condition the edges for welding. The strip then passes through a series of contoured rollers which cold-form the material into a circular (squarSee more on metalsupermarketsStainless Steel Specification - China Guanyu Stainless gb standard steel seamless round tubeDIN 2391.
