welded steel pipe


Welded steel pipe refers to the steel pipes made by curved steel band or steel plates in round, square and etc shape, and then be welded with weld joints on the surface. The raw materials are steel plate or steel band. Separated with different types of welding technique, welded steel pipes can be divided into arc-welded steel pipes, high frequency or low frequency resistance weld pipes, gas-welded steel pipes, bundy pipes and etc. Arc-welded steel pipes are mainly used for oil drilling and machine manufacturing.  There are helical weld pipes and longitudinal welded pipes, two pipes.As for longitudinal welded pipes, the manufacturer technique is kind of simple with low costs and high production efficiency.  The best advantage of pipes is that they can suit for almost all width of steel bands.So the future of welded steel pipes is very bright.
