Product Description

HDPE pipes have been used extensively around the world. It is a cost effective solution for a broad range of piping applications in the municipal, industrial, marine, mining, landfill, duct and agricultural industries.

The Hydraulic butt fusion welding machine, mainly consists of 3 major parts: Carriage (also called frame or base), planing tool (also called trimmer or facer) and heater, hydraulic station with control device. Carriage for precise face joint and steady pipe clamping, planing tool and heater responsible for accurate trimming and heating, hydraulic station provides actuation and control.

To achieve a good jointing, a steady, precise, robust butt welding machine is critical. WELPING had been developing, manufacturing and distributing HDPE welding equipment since 2005. It’s our pleasure to help you build reputation in the piping project.
