ERW straight seam welded pipe, also known as "resistance welded straight seam welded pipe", ERW straight seam welded pipe is mainly divided into ERW alternating current welded pipe and ERW direct current welded pipe. According to different frequencies, ERW straight welded pipe can be divided into low frequency welding, medium frequency welding, ultra-medium frequency welding and high frequency welding. High frequency welding is mainly used in the production of thin-walled steel pipe or common thick-walled steel pipe. High frequency welding is divided into contact welding and induction welding.

ERW straight seam welded pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction in China. For liquid transportation: water supply and drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as piling pipes, bridges, wharfs, roads, construction pipes, etc.
