The machine is used to jointly weld flange plate and its branch pipe and flange on its two sides of steel pipe. Its has three specification: GZH-1012, GZH-1212, GZH-1512. And we can manufacture other specification according to customer’s requirement. The two sides of main worktable is equipped with two suits of self-center with T grooves, three-paw plate. (one suit can move freely within 12m drived by a motor). Thus it ensures the flange is vertical with pipe, and accurant location with flange connecting screw hole.
