Elbow manufacturer Describes how to make elbow in detail  

Elbow manufacturer mainly used in the production process is to push the materials for thermal system first, push the machine head or is a horn core mandrel, mandrel from fine to coarse, elbow push system is an expanding in the process of bending process, back support, under the section material through the mandrel behind the door a memorial arch frame will be fixed mandrel, there is a car, car through hydraulic transmission,  Some through mechanical transmission that is screw drive, and then to push the car, the car pushes the tube along the mandrel go forward, the mandrel has an induction ring, the tube heating, heating, let after the car to push the tube, processing a good.  Next, the correction process is carried out. After shot peening, the iron oxide on the inner and outer surface of the elbow is removed, and the two ends are beveled to facilitate welding.  To select the specification, put forward the pipe material, such as 90 degree elbow, through its curvature can calculate how long the cutting material can be processed into 90 degree elbow and then the length can be fixed length for cutting.  After pushing the elbow, it will be corrected in the hot state, because some elbows will be distorted after improper handling, which is not allowed. In addition, after pushing the head, the front outer diameter is generally large, which should be corrected by correcting touch.  The straightening touch is actually a press, with a set of molds, two semi-arcs, one upper and one lower, and the straightened outer diameter reaches the size of the finished product.  After testing, typing, painting, packaging and other processes through various departments using advanced instruments, it can be transported to the company or construction site specified by the customer.
