PPDW Pipeline Welding

Model specification:

For the pipe diameter of 40-426/ 60-630mm diameter, vessel diameter of 168-830mm or 219-1219mm; Other specifications can be customized. Equipment: the main pressure type pipeline automatic welding machine + pipe - tube welding center + welding power + matching bracket, etc. The Longmen type welding machine + chuck type positioner + drive roller group + welding power + supporting bracket

Equipment use:

This type of automatic welding machine is mainly used in the automatic welding of pipeline, tank vessel, etc.. The combination of the main machine + pipe - tube welding center + welding power + supporting bracket can be realized by using the press type pipeline automatic welding machine.: Using pipe - pipe welding center chuck clamping can be realized, the tube - tube and tube - flange, pipe elbow, pipe three-way, short - head, pipe fittings, pipe tapered pipe workpiece automatic welding; (2) using compression type pipeline automatic welding machine used to host pressing the workpiece and with the supporting bracket support can be realized, the long tube - tube, long tube - conical pipe, a long pipe flange, long pipe elbow, a long pipe - three pass, long - the size of the first workpiece automatic welding. The Longmen type welding machine + chuck type positioner + drive roller group + welding power + supporting bracket: Using gantry welding machine and chuck type variable bit machine chuck clamping can be realized, the tube - tube and tube - flange, pipe elbow, pipe three-way, short - head, pipe fittings, pipe tapered pipe workpiece automatic welding The Longmen type welding machine + drive roller group can realize vessel longitudinal and girth welding

 

 

Welding technology:

Argon arc (TIG/ TIG) Gas protection (GMAW) Argon arc + gas (TIG/ wire TIG+GMAW) Argon arc submerged arc (TIG/ + TIG+SAW wire) Gas shielded + submerged arc (GMAW+SAW) Argon arc gas shielded arc + + (TIG/ TIG+GMAW+SAW) Miscellaneous

Welding quality:

Butt weld backing welding can achieve melt-through bead and bead height control; Butt weld meets the radiographic examination or ultrasonic detection, and the qualified rate of grade I or second grade weld is above 98%.; Meet the requirements of mechanical properties such as impact, tension, bending, etc. Corner welding to meet the angle height and pressure testing requirements.
