SeamlessSteel Pipe
Seamlesssteel pipe is manufactured through hot rolling, cold rolling or cold drawingthe hollow billet which is made with steel ingot or solid bar. It can beclassified as hot rolled seamless steel pipe and cold rolled seamless steel pipe.Low-carbon steel madeseamless steel pipe is mainly used for pipelines, however, medium carbon steelmade seamless steel pipe is used for mechanical parts manufacturing. Comparedwith solid steels of the same bend strength, our product is not only lighterand cost efficient, but multifunctional.
With a complete set of advanced production equipments and quality managementsystem, we are confident to quick accommodate our overseas customers withqualified seamless steel pipe.
