Seamless steel pipes are represented by outer diameter and wall thickness. Thick-walled seamless steel pipes are mainly used for mechanical processing, coal mines, hydraulic steel and other purposes. Thick-walled seamless pipe production is divided into cold-drawn and hot-rolled, and the material is divided into ordinary pipe and alloy pipe. What is a hot rolled seamless steel pipe? - www Jul 10, 2018 · Hot-rolled seamless steel pipe is manufactured by hot rolling technology, as the name suggests, the temperature of rolled piece is high, so the deformation resistance is small to achieve large deformation. Take rolling of steel plate for example, the general thickness of continuous casting slab is about 230mm, and after roughing mill and china galvanized seamless welded steel pipe suppliers-GKSeamless steel pipe is perforated with round steel, the surface of the steel pipe without weld is called seamless steel pipe. According to the production method, seamless steel pipe can be divided into hot rolled seamless steel pipe, cold rolled seamless steel pipe, cold drawn seamless steel pipe, Welding flange of the detailed introduction 07-07
