315 Butt Welding Machine – Central Body & Clamping System

The 315 Butt Welding Machine features a durable design with 4 main pulleys and induction-hardened chrome shafts. Its specially designed piston heads allow smooth operation even at low pressures (3–5 bar), ensuring uniform pulley movement. The machine’s pipe clamping plates, intermediate clamps, and injection-molded plates up to 560 mm in diameter make it significantly more robust and reliable than other models on the market.

Heater Features

The butt fusion machine heater is coated with special Teflon resistant up to 450°C. It includes a replaceable resistance element and consists of two parts, providing safe and efficient heating for plastic pipes.

 

 

Trimmer Features

Equipped with injection-molded bodies and disks, the machine’s trimmer ensures smooth and precise pipe surfaces with a blade height of 0.25 mm. The chain tensioning mechanism allows easy adjustment during summer and winter, preventing potential chain breakage.

 

 

Hydraulic Unit & Control System

The 315 Butt Fusion Welding Machine is powered by an advanced hydraulic unit that manages all operations: heater electrical connection (via digital screen), trimmer control, on/off lever, pressure monitoring via manometer, and forward/backward cylinder movement. Hydraulic valves allow continuous adjustment of welding pressure, maintaining a consistent welding process. The unit is protected against dirt, easy to transport, and designed to accommodate additional fittings and components.

Applications

This machine is ideal for construction sites, workshops, and engineering systems such as water supply and gas pipeline installations. Compatible materials include PE, PP, and PVDF pipes and fittings.

Butt fusion welding of polyethylene pipes requires specialized welding machines. Detailed guidance is available on Heat fusion – Wikipedia.
