Manufacturing process of large diameter seamless elbow

The company mainly according to customer requirements to produce a variety of different models and angles of large diameter seamless elbow pipe products, there are 45 degrees of large diameter seamless elbow, 90 degrees of large diameter seamless elbow and various angles of elbow. According to the material, it can be divided into carbon steel large-caliber elbow, stainless steel large-caliber elbow, alloy steel large-caliber elbow. According to the curvature radius of large diameter elbow, it can be divided into long radius large diameter elbow and short radius large diameter elbow.

The production process of large diameter seamless elbow manufacturers mainly adopts: pushing blank material, wall thickness and outer diameter, mandrel head material and shape, heating temperature and part of the speed of propulsion production forming.

At present our company can according to customer requirements and production process production: mainly divided into hot push, stamping, extrusion and so on.

All orders of large diameter seamless elbow pipe fittings in our company customers in our company adopts thermal pushed the process of forming process, the hot pushing elbow forming process mainly USES the common bend machine and mold and heating equipment, is set in the mold of billet in pushing forward movement, under the impetus of the machine in motion is heated, hole diameter and forming. Hot push bend deformation characteristics is according to the metal materials of the specifications of the plastic volume before and after determine the pipe diameter, the tube billet diameter used is less than the diameter of the seamless elbow pipe fittings, through core module and control the deformation of the process, is the internal arc compressed metal flow, the compensation to the other parts of the thinned by expanding, to get a uniform wall thickness seamless elbow pipe fittings products.

Hot push seamless elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous production, appetite mass production, so called, carbon steel, alloy steel, seamless elbow main forming process, can be used in some specifications of stainless steel elbow forming.

The heating method in the forming process has medium frequency or high frequency induction heating ring can be multi-ring or single ring, heating and reflector heating, which heating method depends on the forming product requirements and various specifications. Customer word our company large diameter seamless elbow pipe fittings, our company sincerely for each customer service.
