Carbon steel pipe is a spiral seam steel pipe with a steel coiled plate as a raw material, which is often extruded and formed by welding with an automatic double-wire submerged arc welding process. The spiral steel pipe feeds the strip steel into the welded pipe unit, and after being rolled by multiple rollers, the strip steel is gradually rolled up to form a round tube blank with an open gap. 3mm, and make the two ends of the welding port flush.

Product Display

The production of our carbon steel pipes is tightly regulated and all of the pipes we produced have been fully tested to international standards to ensure we only supply the hightest products.

Carbon Steel Pipe

We have a series of production processes, and the stock is abundant, and the seamless carbon steel pipe is widely used.
The steel pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipe has the same bending and torsional strength, and is lighter in weight. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, Bicycle racks and steel scaffolding used in building construction, etc.
