manualfor plastic pipefor thermoplastics

Overview
Hydraulic hot-melt butt fusion welding machine designed for welding HDPE, PE, PP and PVDF pipes. Built to meet infrastructure requirements for water, gas, mining and industrial fluid systems. Complies with DVS 2207, ISO 21307 and ASTM F2620 standards.

Key Features

• Hydraulic drive ensures stable pressure during the welding cycle.
• Accumulator for maintaining consistent pressure throughout fusion.
• Circuit breaker with leakage protection for electrical safety.
• Durable solid relays for higher load capacity and longer service life.
• Advanced temperature-controlled switch for accurate heating.
• Safety valve mounted on the hydraulic block.

Applications
Suitable for municipal water supply and drainage, potable water systems, wastewater treatment, gas distribution pipelines, industrial fluid transfer, mining pipelines, geothermal heating/cooling, aquaculture, agricultural irrigation and HDPE boat construction. Delivers consistent, long-lasting fusion joints for thermoplastic piping systems.
