OverviewHigh-precision automatic butt fusion welding machines for joining PE, PP, PPR and PVDF pipelines (90–355 mm) used in oil & gas gathering, water supply, wastewater, mining and other industrial applications. These units combine CNC hydraulic control, PLC touch-screen interface, DuPont Teflon-coated heating plate and RFID/advanced data logging to ensure reliable, reproducible and durable welds.
Key built-in functions and features- Print-capable welding report storage (up to 2000 records) with USB export for traceability.
- DuPont Teflon-coated heating plate (anti-stick) to reduce adhesion and improve temperature stability.
- Narrow single reducer inserts and optional ISO single inserts for flexible pipe-sizing.
- Fully integrated CNC hydraulic controller with robust PLC touch-screen for automated, repeatable welding cycles.
- RFID technology and advanced data logging for user/parameter traceability.
- Lightweight aluminum clamps and compact, space-saving design for on-site transport and operation.
- Premium oil-seal kit from Germany and four STUCCHI quick couplings (Italy) to reduce hydraulic leaks and simplify setup.
- Integral chromate-treated shaft to improve chassis rigidity and resist frame twisting under load.
- Heating plate uniformity approx. 2–3°C for smaller units and 5–6°C for larger units; safety trimmer switch and ergonomic support system for operator comfort.
Applications- HDPE, PE, PP and PVDF pipeline welding for potable water distribution and supply networks.
- Wastewater collection systems and water treatment plants.
- Mining and industrial fluid transfer pipelines.
- Gas pipeline construction and oil & gas gathering systems.
- Geothermal heating/cooling, municipal infrastructure, agricultural irrigation and HDPE boat constructions.
Included / notable accessories and options- DuPont Teflon-coated heating plate; optional reducer inserts covering multiple diameters.
- STUCCHI quick couplings for hydraulic connections; premium oil seals; RFID/data logging and USB report export.
