Seamless steel pipes / tubes

Seamless steel pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless steel pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids.

It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members. Seamless pipe is thought to be able to withstand higher pressure, higher temperatures, higher mechanical stress and a corrosive atmosphere. It can be found in a wide range of applications such as in oil and gas, refinery, petrochemical, chemical, fertilizer, power, automotive, bearing, mechanical and structural.

The production of our seamless pipes is tightly regulated and all of the pipes we stock have been fully tested to international standards to ensure we only supply the highest quality products.

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.
