The stamping elbow
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.
Seamless elbow pipe fitting
The raw material of the seamless elbow is the round tube billet, which is cut and processed by a cutting machine with a length of about one meter billet, and sent to the furnace for heating by conveyer belt.After perforating, the round tube billet is rolled, rolled or squeezed by three rods.After extrusion the pipe should be removed to size.The sizing machine rotates at high speed into the steel blank for drilling and forming pipe fitting.
Because of the different manufacturing process, seamless elbow can be divided into hot rolled seamless elbow and cold drawn seamless elbow pipe fittings.
Seamless elbow specification :DN10-DN2000
Seamless elbow material: through, cast steel, alloy steel, stainless steel, etc.
Seamless elbow production technology: push, press, forging, casting, etc.
Seamless elbow production standards: GB, electric standard, water standard, American standard, German standard, Japanese standard, British standard, etc.
Seamless elbow has good wear resistance, strong pressure resistance, corrosion resistance, used in high temperature pressure pipeline and mechanical equipment.
