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.

The characteristics of galvanized steel pipe:Both black and galvanized steel tubes are made of steel, but galvanized steel tubes have zinc coating, while black steel tubes do not.So it's a good distinction.How does galvanizing protect steel pipe?Galvanized steel pipe is a layer of galvanized protect

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.
