Description

Product Overview
High-pressure butt fusion machine manufactured in steel and aluminum, designed for welding HDPE, PP and PVDF pipes used in water, gas and infrastructure projects. Compliant with ISO 21307 and ASTM F2620 to deliver precise and reliable butt fusion joints suitable for site and factory conditions.

Key Features
  • Wide welding range: 315–630 mm (12″–24″ IPS) to cover multiple project requirements.
  • Robust hydraulic system: precise pressure control for consistent joint integrity (0–180 BAR).
  • Teflon-coated heating plate: uniform heating and extended plate service life.
  • User-friendly control panel: adjustable welding parameters and simple operation for field teams.
  • Safety systems: integrated temperature sensors and emergency stop for operator protection.


Additional Description
This high-performance butt fusion machine includes trimming and pump units for end preparation and hydraulic operation. Modular reducer inserts (315, 355, 400, 450, 500, 560) and multi/ISO/single insert compatibility allow fast configuration for different pipe diameters and standards.
