Stamping elbow is divided into: carbon steel stamping elbow, stainless steel stamping elbow, alloy stamping elbow, according to the standard is divided into: GB stamping elbow, non-standard, standard, : German standard, Japanese standard, American standard, British standard stamping elbow.
Stamping elbow forming process is complicated, need according to the use of the different material and welding, forming gradually, under the pressure of certain stamping elbow forming shall be carried out according to certain procedure, strictly abide by the corresponding process flow, or produce the stamping elbow can produce quality problem, the large stamping elbow molding technology of the basic process is: welding a cross section of a polygon or both ends closed multi multi ring shell fan shell, when the internal pressure medium, full with inner pressure and internal pressure under the action of cross section has a polygon gradually became round, and eventually become a circular ring shell.
The raw material of the seamless elbow is round tube billet, which is cut by the cutting machine and processed into billet with a growth degree of about one meter, and sent to the furnace by the conveyor belt for heating.After the perforation, the billet is cross-rolled, continuously rolled or extruded by three rods.Remove the tube and size after extrusion.The sizing machine penetrates the steel blanks through a tapered drill with high speed rotation to form pipe fittings.
Seamless elbow because of its different manufacturing process, and divided into hot rolled seamless elbow pipe fittings and cold drawn seamless elbow pipe fittings two.
Seamless elbow specification :DN10-DN2000
