Socket Welded Line Pipe :
Carbon Steel Socket Welded Line Pipe :
Pipeline steel is used for transporting oil,gas and other large diameter welded steel pipe with hot rolled coil plate or lenient plate.Pipeline steel in use process,in addition to the requirement has high compression strength,also requires a high low temperature toughness and excellent welding performance.
