Butt welding machine SWT-V160/63SHP

manualfor pipesfor thermoplastics

High-pressure butt fusion welding machines for PN25 HDPE water pipes, covering pipe sizes from 63 mm to 355 mm. Built on a precision-machined aluminum chassis with cartridge hydraulic valves and a Makita-driven worm trimmer to deliver consistent thermofusion welding for water, gas, industrial and mining pipelines.

Key features

• Hydraulic cartridge valves for simplified maintenance and fast repair.
• Trimmer driven by a Makita electric drill with worm/turbine power system for stable beveling and end-prep.
• Outer and inner clamps machined from engraved aluminum to prevent pipe slippage and ensure concentric clamping.
• Hydraulic hoses on the frame made of stainless steel to resist corrosion and cracking.
• Heating plate with Dupont PTFE (Teflon) coating and stainless-steel junction box for durability and easy cleaning.
• Cylinder and tie rod in stainless steel; sealing rings from internationally recognized brands for reliable pressure retention.
