Longitudinal welded pipes, steel pipes made of hot-rolled or cold-rolled steel plates or steel strip coils welded on welding equipment are called straight seam welded pipes. (It gets its name because the welding of the steel pipe is in a straight line). It is made of steel plate or steel strip after bending and then welding. According to the weld form, it is divided into straight seam welded pipe and spiral welded pipe. According to the purpose, it is divided into general welded pipe, galvanized welded pipe, oxygen blown welded pipe, wire casing, metric welded pipe, idler pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welded thin-walled pipe, electric welded special-shaped pipe and spiral welded pipe.
