Product Overview
Hydraulic butt fusion welder designed for installation and repair of HDPE, PP and PVDF pipelines in water, gas, mining and industrial fluid systems. Compliant with DVS 2207, ISO 21307 and ASTM F2620 welding standards for butt fusion processes.

Key Features

• Circuit breaker with earth-leakage protection for operator and site safety.
• High-capacity solid relays to support heavier loads and extended service life.
• Advanced temperature-controlled switch for consistent heating plate performance.
• Integrated accumulator to stabilize hydraulic pressure during welding cycles.
• Safety relief valve mounted on the hydraulic block to prevent overpressure.

Description
The SWT-V315/90H is a hydraulic butt fusion machine engineered for reliable, repeatable fusion joints on pipes from 90 to 315 mm O.D. Its hydraulic drive and pressure accumulator ensure uniform heating and controlled cooling, delivering strong, long-lasting welds suitable for potable water, gas distribution and industrial pipelines.
