This high-pressure automatic butt fusion machine (nuclear-grade butt welding machine) is engineered for high-pressure PE, PP, PVDF thermoplastic pipeline welding, widely adopted for nuclear power projects, gas and chemical high-pressure piping systems. It meets ASTM, ISO, DVS & Chinese welding standards, featured with international patented clamps, heater drop-off alarm function, ambient temperature compensation, data logging & built-in printer, delivering traceable, high-precision welding quality for critical high-pressure pipeline jobs, suitable for both on-site construction and workshop pre-fabrication.
Body/Heater/Trimmer:
Firm and compact frame is convenient and suitable for usage at construction site.
Fasten pipe conveniently and accurately thanks to clamps with international patent.
Heater and pipe can be separated automatically and easily thanks to the new type of heater drop alert.
Clamps meet ASTM standards, ensuring accuracy when connecting pipes.
Automatic controller:
User friendly operation interface, allowing operators to carry out fusion welding work conveniently with ease.
Features environment temperature compensation, automatically controlling heating temperature and cooling time , guarantee fusion quality.
Automatic construction site information classification. Welding data at the same site will be stored automatically for convenient construction management.
The display is equipped with back-lighting. This will enable operator to work in poor lighting and at night.
You can check and review fusion process data on the display before printing.
The built-in printer can print and check fusion data.
Printer output data including dates, external temperature, heating temperature, the site data, tensile pressure, fusion pressure, pipe material specification, fusion results, cooling time etc. Those parameters that can be used to confirm the fusion process.
This machine has been certified by South Korea Gas Safety Association.
Optional Accessories
Special clamps for welding short flange
Flange Stub
Single clamps
