Usage:

Steel pipe are ubiquitous and can be found underground and within residential walls, laboratories, and commercial and industrial structures. Seamless steel pipe transport fluids including water, natural gas, waste and air. Three manufacturing methods exist to produce steel pipes.

Seamless steel pipes are produced using an extrusion mold. Welded steel pipes are produced by rolling a sheet of steel into a tube and welding the seam. Seamless steel pipes are less expensive. The third method is casting. Molten steel is poured into a casting mold.

Our steel pipes and tubes are the preferred choice for processes under the following conditions:

We have a team of experienced professionals with years of experience in manufacturing.
