Feature
The working range for small diameters covers 4" to 24".
Capable of meeting the requirements for a 6D turning radius.
Features inflatable ring-type backing gas protection to ensure the back of the weld is free from oxidation.
Independent air intake channels and a sealed shielding gas chamber system effectively prevent internal and external air flow, ensuring low oxygen content within the sealed space and improving welding quality.
Powerful tension provides up to 70 times the pipe reshaping capability compared to pneumatic systems.
Widely used in petroleum, chemical, natural gas, boiler, nuclear power, plant line construction, and pipeline engineering, etc.
The products have been successfully applied in composite pipe projects constructed by Sichuan Oil Construction, China Petroleum First Construction, Daqing Oil Construction, and Dagang Oil Construction, etc. They feature good joint alignment, high construction efficiency, and have been highly recognized by the project units.
