Seamless elbow
Seamless elbow is a kind of pipe fitting used in pipe turning. It accounts for a large proportion of all pipe fittings used in pipe system. Usually different forming processes are selected for elbows with different material wall thickness. Manufacturers commonly used seamless elbow forming processes are hot push, stamping, extrusion and so on.
Seamless elbow is made of seamless steel pipe, seamless elbow pipe fittings in the manufacturing process is different, there are two kinds of hot rolled extrusion seamless elbow pipe fittings and cold drawn seamless elbow pipe fittings. Cold drawn pipe is divided into circular guanhe shaped pipe two.
The raw material for seamless elbow fittings is round tube billet, which is cut by a cutter and processed into billet of about one meter in length, and then sent to the furnace for heating. The billet is sent to the furnace for heating at a temperature of about 1200 degrees Celsius. The fuel is hydrogen. The temperature control in the furnace is the key problem. After the round tube billet is out of the oven, it is perforated by the pressure puncher. Generally, the common puncher is the conical roller puncher. After perforation, the billet is cross-rolled, rolled or extruded by three rolls successively. After extrusion, the pipe should be removed and sized. The sizing machine is used to drill holes into billets by rotating a conical bit at high speed to form pipe fittings.
