Description

High-pressure thermofusion (butt fusion) welding machines for large-diameter thermoplastic pipes — models SWT-V1000/630SHP and SWT-V1200/630SHP.

Overview
  • MM-Tech machines designed for butt fusion welding of HDPE, PE, PP and PVDF pipes in demanding environments such as mining, water infrastructure and gas distribution.
  • Suitable for large diameters with model options covering 630–1200 mm.


Key features
  • Innovative "3+1" frame design to improve stability when welding short spigot fittings.
  • High-precision hydraulic control using oil seals, quick couplings and pressure valves from reputable suppliers (Japan, USA, Italy).
  • Thick Teflon-coated heating plate to reduce temperature differentials and minimize adhesion.
  • Powerful single-sided double-blade milling cutter for efficient and accurate pipe end preparation.
  • Human-centered interface and intuitive controls for straightforward operation and improved productivity.
  • Multiple integrated safety protection mechanisms to reduce operator risk.
  • Applications: water infrastructure, gas distribution systems, industrial pipelines and mining pipelines.
  • CE certification; 2-year warranty and professional technical support available.
