Steel Pipe

Steel Pipe

Steel pipe is used totransport fluid, powdered solid and transfer thermal energy. Steel pipe arecategorized as seamless steel pipe and welded steel pipe according to differentproduction technologies. Seamless steel pipe hashot rolled seamless pipe, cold drawn pipe, precision steel pipe, thermalexpansion pipe, spinning pipe and extruded pipe types. The welded steel pipe iscategorized as furnace pipe, electric resistance welding pipe and automatic arcwelding pipe according to different welding technologies.

In addition,welded pipe has butt welding pipe and spiral welded pipe types, round weldingpipe and non-round pipe according to different transverse plates. The weldingsteel pipe is produced by coiling and connecting steel plate by means ofwelding and also can be categorized as low pressure fluid transporting weldingpipe, spiral welding pipe and ERW pipe. Usually the seamless steel pipe is usedto transport liquid and gas, while welding steel pipe is used to transportwater, coal gas and heat.
