Information
(1) Seamless steel pipe. Seamless steel pipe is made of a whole piece of metal with no seams on its surface. According to different production methods, seamless steel pipe can be divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking and so on. Seamless steel pipes are mainly used for oil drilling pipes, cracking pipes for petrochemical industry, self-drilling hollow bolts, bearing pipes, etc.
(2) Welded steel pipe. Welded steel pipes are steel pipes with welded seams on the surface. According to different welding methods, welded steel pipe is divided into arc welded pipe, resistance welded pipe (high frequency, low frequency), gas welded pipe, furnace welded pipe and so on. From the weld seam, the welded pipe has straight seam welded pipe and spiral seam welded pipe. Welded steel pipe has higher productivity, lower cost and wider application than seamless steel pipe.
