Processing method of large diameter large-caliber pipe fitting tee

　　Large-caliber pipe fitting tee is also a kind of common pipe fittings. A section of main pipe plus a small branch pipe is named because the tee is pressed after heating, and the tonnage of equipment required for material forming is reduced. A234 Wpb Seamless Carbon Steel Large-Caliber Pipe Fitting Tee is used for precision seamless pipe with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment. In the pure oxygen pipeline, there is pressure generally, so the activity of oxygen is stronger; large-caliber pipe fitting tee can be used to avoid, because the sundries in the pipe move with the oxygen flow, and when the flow speed changes, the sundries collide with the pipe to produce a fire source or electrostatic discharge due to the change of flow speed, which may cause the fire of the pure oxygen pipe.

　　Mark the large-caliber pipe fitting tee where the pipe is to be processed, and punch through the mark. The outlet device is arranged on the pipeline, which includes metal, jacking device, commutator, bracket, etc.; the metal bar is heated, and when the jack and metal bar are used to push out, the pipe wall material naturally turns out to form the large-caliber pipe fitting tee blank; then the pipe section with a certain length and corresponding specification is welded on the large-caliber pipe fitting tee blank formed by pushing out.
