Seamless elbow manufacturer

Description :

　　The seamless carbon steel elbow forming process is suitable for manufacturing any elbow with a working pressure of less than 10MPa, an inner diameter of d125mm, and a ratio of D/d1.5 between the elbow diameter D and the inner diameter d, and the size of the elbow diameter is not limited. For example, large elbows with an inner diameter of 12m and a center diameter of over 60m can be processed. The basic process of forming carbon steel elbows is as follows: first, weld a polygonal multi sided ring shell or a multi sided fan-shaped shell with closed ends. After filling the interior with pressure medium, apply internal pressure. Under the action of internal pressure, the cross-section gradually changes from polygonal to circular, and finally becomes a circular ring shell. According to the needs, a circular ring shell can be cut into 4 90 elbows or 6 60 elbows or other specifications of elbows. This process is suitable for manufacturing large elbows of any size with a ratio of elbow diameter to elbow inner diameter greater than 1.5, and is currently the ideal method for manufacturing large pressure elbows.

　　The carbon steel seamless elbow forming process of 90 degree seamless elbow manufacturer is suitable for manufacturing any elbow with a working pressure less than 10MPa, an inner diameter of d125mm, and a ratio of D/d1.5 between the elbow diameter D and the inner diameter d, and the size of the elbow diameter is not limited. For example, large elbows with an inner diameter of 12m and a center diameter of over 60m can be processed.

　　According to the angle of the bend, there are 45 bends, 90 bends, and 180 bends. Taituo Company uses specialized elbow pushing machines, core molds, and heating equipment to produce hot pressed elbows. The billet placed on the mold moves forward under the pushing of the pushing machine, and is heated, expanded, and twisted into shape during the movement. The deformation characteristics of hot push elbows are determined based on the rule that the volume of the metal material remains unchanged before and after plastic deformation. The selected billet diameter is smaller than the elbow diameter, and the deformation process of the billet is controlled by the core mold, causing the metal at the inner arc to be compressed and compensated for by the thinning of other parts due to diameter expansion, and then obtaining a hot press elbow with uniform wall thickness. Due to its strong impact resistance, long service life, high production efficiency, and reliable quality, hot press elbows are easy to automate, with sturdy and reliable connections, simple operation, and easy use; So the products produced by our Hebei Hot Pressing Bend Factory have been widely used in occupational construction and maintenance sites such as petroleum, chemical, power, metallurgy, shipbuilding, gas, urban construction, and environmental protection.
