On June 19, 2020, the 2850-3000mm high-pressure hot-melt butt welding machine test was completed. This is the largest welded pipe welding machine produced so far in China. It officially sailed on July 1, 2020 and was sent to Saudi Arabia for Used by local desalination projects.

This equipment can operate the opening and closing of pipe clamps through a tablet PC operation, and it is a high-pressure technology that can reduce the welding and cooling time during the welding process. The data can be printed in time when each section of pipeline is welded.
