Seamless steel pipes, as the name suggests, have no seams and are produced by hot rolling and cold rolling. Welded pipe, on the other hand, is made by rolling coils of steel to the required gauge thickness, a manufacturing process that leaves seams in the pipe body. The next stage is to cut the joints to a width that corresponds to the size of the pipe to be constructed.

Stainless steel tubing features seamless and welded tubing, cold worked, annealed and pickled in a range of diameters and stock lengths.Offering 304/304L and 316/316L alloys, our stainless steel tubing mixes corrosion resistance and strength and is ideal for use in harsh conditions such as brine, ch

3LPE coated seamless steel pipes are high-quality pipes that are coated with a three-layer polyethylene coating. The three-layer coating consists of a fusion-bonded epoxy layer, an adhesive layer, and a polyethylene layer. This coating provides excellent protection against corrosion, making it ideal for use in harsh and corrosive environments.
