Seamless pipe Welded steel pipes

1)The main products are round pipes (seamless pipes, galvanized pipes,welded pipes), square pipes, rectangular pipes, etc. Seamless pipe is a longsteel with a hollow section and no joints on the periphery. A large number ofpipelines are used to transport fluids, such as pipelines for transporting oil,natural gas, gas water and certain solid materials. Compared with solid steelsuch as round steel, steel pipe has the same bending and torsion strengthand lighter weight. lt is a kind ofeconomical cross-section steel, which iswidely used in the manufacture of structural parts and mechanical parts,such as oil drill pipes, automobile transmission shafts, Bicycle racks and steelscaffolding used in building construction, etc.

2)Welded steel pipes, are steel pipes made by welding steel or strip steelafter crimping. Welded steel pipes are divided into straight seam weldedpipes and spiral welded pipes according to the form of welds. According todifferent welding methods, it is divided into arc welded pipe, (high frequency,low frequency) resistance welded pipe, gas welded pipe, furnace weldedpipe, Bondi pipe, etc.

3)Most of the square and rectangular pipes are weldedpipes, which are widely used in machinery manufacturing.construction, metallurgical industry, agricultural vehicles,agricultural greenhouses, automobile industry, railways,highway guardrails, container frameworks, furniture, deco.ration, and steel structure fields.
