Carbon Steel Pipe 12 Inch Urban Construction Pile Driving Pipe ERW Steel Pipe

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.

The welding is pressure bonding rather than molten welding. According to the use of the material, the internal and external welding burrs can be clean. According to the different welding technology of high frequency straight seam welded steel pipe can be divided into straight seam high frequency resistance welded steel pipe and straight seam high frequency induction welded steel pipe.The forming process generally adopts the rolling cold forming method.

Welding to the work piece can not be cleaned,can be welded thin wall pipe, welding metal pipe.

Due to the use of hot rolled coil as raw material, the wall thickness of ERW steel pipe can be controlled within ±0.2mm or so, the two ends of the steel pipe are in accordance with the American APL standard or GB/T9711.1 standard, the end is repaired and beveled, and the delivery length is fixed.In recent years, various natural gas pipeline engineering and gas companies have widely adopted ERW steel pipe as the main pipe of urban pipeline network.
