45Deg seamless bend butt welded bevel pipe fittings seamless steel pipe
Seamless elbow pipe fittings for its manufacturing process is different, is divided into hot rolling (extrusion) seamless elbow pipe fittings and cold drawing (rolling) seamless elbow pipe fittings. Cold drawing (rolling) pipe is divided into circular tube and special-shaped tube two kinds.Now its technological process simple introduction is as follows:A cold drawing (rolling) seamless elbow pipe fittings, pipe billet and heating to punch to heading, annealing, pickling and oil (copper) and multichannel time cold drawing (cold rolled) to the tube billet – heat treatment – straightening, hydrostatic test (NDT) – > tag to put in storage.2. Hot rolled seamless elbow pipe fittings (extrusion) : the circular tube billet – heat – punch – three-roll skew rolling, rolling, or pressing – to take off the tube and sizing (or reducing) – cooling – straightening to hydrostatic test or inspection – > tag, put in storage
Carbon steel seamless elbow after sizing, into the cooling tower, by water spray cooling, pipe after cooling, will be straightening. Pipe by the conveyor belt to the metal detection after straightening machine (or water pressure experiment) for internal inspection. If the steel pipe internal crack, air bubble, will be detected. Seamless elbow pipe fittings quality through rigorous after manual pick. Seamless elbow after quality inspection, spray paint on the serial number, specification, batch number, etc. Seamless elbow and by crane into the warehouse.
