Stainless steel seamless elbow manufacturer

In the piping system, the elbow is to change the direction of the pipe fittings. Angularly points, 45 ° and 90 ° 180 ° three most commonly used, according to project needs in addition also includes other non-normal 60 ° angle bend. Stainless steel elbow elbow distinguished mainly of different materials, the chemical composition of its surface contains the elbow will remain for a long time will not rust and will not corrode. Seamless pipe elbow is a pipe for a corner. All fittings in piping systems to use more, the largest proportion, about 80%. Generally, the material goods of different thickness elbow choose different forming processes. Currently. Factory usual seamless elbow hot push forming process, stamping, extrusion and other seamless elbow, also known as the English name of seamless elbow seamless steel elbow or seamless pipe elbow, seamless elbow pipe because of different manufacturing processes, It is divided into hot-rolled (extrusion) seamless elbow pipe and cold drawn (rolled) seamless pipe elbow two kinds. Cold drawn (rolled) pipe is divided into two kinds of circular pipe and shaped pipe. Rolled seamless elbow pipe materials is round tube, tube embryos to go after cutting a length of about one meter cutter blank, and by conveyor belt to the furnace heating. The billet is fed into the furnace is heated to a temperature of about 1200 degrees Celsius. Furnace temperature control is the key issue. After the round tube came to pass through air pressure punching machine. Generally more common punch is tapered roller puncher, punch this high production efficiency, product quality, perforated expanding capacity, can wear a variety of pipe fittings. Perforation, round tube has been three-roll rolling, rolling or extrusion. After pressing to take off pipe sizing. Sizing machine rotating at high speed through the cone drill steel embryo into perforated to form the tube.
