Product Description

Product Description

SEAMLESS STEEL PIPE

Seamless carbon steel pipes are made of steel ingots or solid tube blanks perforated into capillary tubes and then made by hot rolling, cold rolling, or cold drawing, which have excellent durability and corrosion resistance characteristics. 

Carbon Steel Seamless Pipe Uses
- Carbon Steel Seamless Pipes used in Textile machinery.
- Carbon Steel Seamless Pipes used in the Oil and gas industry
- Carbon Steel Seamless Pipes Uses in Medical Gas Pipeline Systems
- Carbon Steel Seamless Pipes used in the Pharmaceutical processing industry
- Carbon Steel Seamless Pipes Used in Fluid piping.
- Carbon Steel Seamless Pipes Used in Modern architecture.
- Carbon Steel Seamless Pipes Used in Water waste projects.

Application
Carbon steel seamless pipes are extensively applied in the nuclear device, gas conveyance, petrochemical, shipbuilding, and boiler industries, with characteristics of high corrosion resistance combined with suitable mechanical properties.
