API 5L Carbon Steel Pipe
Product Description

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.

Product Features
Compared with other metal pipes, carbon steel pipes have the following characteristics:
1. Good mechanical properties: Carbon steel pipes have high strength, good rigidity and excellent seismic resistance.
2. Light weight: Compared with other metal pipes such as cast iron pipes and alloy steel pipes, carbon steel pipes are lighter and easier to transport and install.
3. Corrosion resistance: The surface of the carbon steel pipe is sprayed with anti-rust and anti-corrosion treatment to extend its service life.
4. Low cost: The production cost of carbon steel pipes is relatively low, and the cost advantage is obvious.
