Butt welding machine SWT-V160/63H

manualfor pipesfor plastics

Hydraulic butt fusion welding machines engineered for reliable, on-site fusion of thermoplastic pipes (HDPE, PE, PP, PVDF) used in potable water, wastewater, mining, geothermal and industrial piping projects. Available in two models to cover OD 63–160 mm and 63–200 mm with a compact, service-friendly design for field use.

Main features

• Hydraulic power station with sufficiently rated motor to ensure stable performance under continuous operation.
• Integrated accumulator to maintain and replenish hydraulic pressure during the welding cycle.
• Heating plate coated with DuPont Teflon for long life and reduced molten material adhesion.
• Quick couplers and pressure valves from Stucchi for secure, low-leakage hydraulic connections.
• Integral chassis frame with quick-disconnect design for fast maintenance; robust construction to resist deformation and oil leakage.
• High-quality hydraulic components sourced from leading suppliers (Germany, Italy, Japan) for long-term reliability.
• Trimmer and heating plate use premium Teflon; stainless-steel junction box and drill-driven trimming tool with ergonomic handle for precise pipe preparation.
• Power station rated for hydraulic pressures up to 80 bar; cartridge valves for simplified maintenance and precise temperature control (typical stability ±3 °C).
