Butt welding machine SWT-V1000/630H

automaticlarge-diameterfor pipes

Heavy-duty hydraulic butt fusion welding machine designed for large-diameter thermoplastic pipe joining in water distribution, gas, mining and industrial systems. Built for continuous field and plant use, it supports welding of HDPE, PE, PP and PVDF pipes with stable temperature and pressure control.

Key features

• Circuit breaker with electrical leakage protection for operator safety.
• STUCCHI quick couplings for secure, low-leak hydraulic connections.
• DuPont Teflon-coated heating plate to reduce adhesion and extend plate life.
• Hydraulic accumulator to stabilise welding pressure during the cycle.
• High-power, fanless motor design to deliver required torque for large-diameter pipes.
• Compact, robust chassis resistant to deformation and oil leakage; hydraulic components sourced from leading suppliers (Germany, Italy, Japan) for reliability.
• Heating plate and facing tool with precise temperature control (typical stability ±7°C per side) and stainless-steel junction box for corrosion resistance.
• Integrated powerful electric drill for efficient, accurate pipe facing; ergonomic handle for operator comfort.

Applications

• Potable water distribution and municipal waterworks.
• Wastewater and sewer pipelines.
• Natural gas distribution networks.
• Mining pipelines and industrial fluid transfer systems.
• Geothermal heating/cooling circuits and large-diameter infrastructure.
• Aquaculture cages, HDPE boat construction and agricultural irrigation works.
