Product Introduction

Fabrication method of elbow

1. Stamping

According to different materials, cold pressing or hot pressing can be selected to put the tube blank into the outer mold. After the upper and lower molds are combined, the tube blank moves along the gap reserved between the inner mold and the outer mold under the push of the press to complete the forming process.

2. Medium plate welding

The medium plate welding is aimed at the production of large elbows. First cut two medium plates, and then press them into half of the elbow profile with a press, and then weld the two profiles together. In this way, the elbow will have two welds. Therefore, after the fabrication, the welds must be tested to meet the standard.
