■ Overview
Seamless (SMLS) steel pipe is formed by drawing a solid billet over a piercing rod and round bars to create the hollow shell. As the manufacturing process does not include any welding, seamless steel pipes are perceived to be stronger and more reliable.Historically seamless pipe was regarded as withstanding pressure better than any other types of weld pipes.Seamless steel pipes are mainly applied to the heat exchangers, condensers and heat transfer equipments and oil&gas transport projects.
