Alloy steel pipes are ubiquitous and can be found underground and within residential walls, laboratories, and commercial and industrial structures. Alloy steel pipe transport fluids including water, natural gas, waste and air. Three manufacturing methods exist to produce steel pipes.
Alloy 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:
– high temperatures
– aggressive media (e.g. acid and lye)
– and/or high pressure
which call for the use of high-quality materials.
Stainless steel tube for Heat exchanger A heat exchanger is a piece of equipment built for efficient heat transfer from one medium to another. The media may be separated by a solid wall to prevent mixing or they may be in direct contact.
