SS400 Steel ERW Steel Pipe Astm A53 Grade B Water Engineer

SS400 Steel Grade As Astm Standard Water Engineering ERW Steel Pipe

High-frequency straight seam welded steel tube process: longitudinal shear -- uncoiling -- strip flattening -- head and tail shear -- strip butt welding -- sleeve storage -- forming -- welding -- removing burrs -- sizing -- flaw detection -- flying cut -- initial inspection -- straightening of steel tubes -- pipe section processing -- hydrostatic test -- flaw detection -- printing and coating -- finished products.High frequency straight seam welded steel pipe is mainly used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction.For liquid transport: water supply, drainage.For gas transmission: gas, steam, liquefied petroleum gas.

The welding is pressure bonding rather than molten welding. Compared with molten welding, the welding heat affected area is relatively small and has little influence on the microstructure of the base material.After welding, the strength and toughness of the weld are different from that of the parent.According to the use of the material, the internal and external welding burrs can be cleaned or not.Welding to the work piece can not be cleaned, can be welded thin wall pipe, welding metal pipe.

ERW steel pipe is straight seam Resistance Welding pipe, English Electric Resistance Welding, abbreviated as ERW, used for transporting oil, natural gas and other vapor liquid objects, can meet the high and low pressure requirements, currently in the world's transportation pipe field occupies a pivotal position.
