Hydraulic Butt Fusion Welding Machine 63-1200mm

Overview

Why Butt Fusion Is the Gold Standard for Plastic Pipe Jointing

Butt fusion is the only pipeline jointing method that creates a weld as strong as the pipe itself. Unlike mechanical couplings that loosen, rubber rings that degrade, or solvent welds that weaken over time, a properly butt-fused joint is a homogeneous molecular bond between two pipe ends. Our hydraulic butt fusion welding machine delivers this reliable joint through three precision-controlled phases: planing (mirror-smooth pipe facing), heating (PTFE non-stick plate at an adjustable 270°C maximum), and fusion (hydraulic pressure maintained throughout the critical cooling cycle). For contractors installing HDPE pipe for water, gas, mining slurry, and industrial chemicals, this butt fusion machine is the single most important piece of equipment on site.

◆ Hydraulic Power Pack — Stable Pressure, No Pressure Drop. Machines above DN110 require consistent fusion pressure that manual levers cannot maintain. Our hydraulic butt fusion machine uses an independent power pack with high-quality valves and seals to maintain precise pressure from the heating phase through the full cooling cycle. Pressure range 0–6.3 MPa, adjustable to match pipe SDR and material requirements. Zero pressure drift means the joint sets correctly every time.

◆ One Machine, 11 Pipe Sizes. Each butt fusion welding machine covers a specific diameter range with reducing inserts. A single DN63–315mm machine handles 63/75/90/110/125/140/160/180/200/225/250/280/315mm pipes by swapping the aluminum clamps. Rugged steel frame with four-point clamping ensures perfect pipe alignment regardless of diameter within the machine's rated range.

◆ PTFE-Coated Heating Plate — No Sticking, Long Life. The heating plate features high-quality non-stick PTFE coating that prevents molten PE from adhering during the heat-soak phase. Intelligent temperature controller maintains accuracy within ±3°C. Clean the plate with a soft cotton cloth while warm after each use — never use metal scrapers, as they will damage the PTFE and cause pipe sticking.

◆ Safety-First Planing Tool — Perfect Face Every Time. The independent electric milling cutter features a safety limit switch to prevent accidental startup. High-quality bi-metallic blades face both pipe ends simultaneously, ensuring perfectly parallel surfaces for the fusion bond. Durable design handles thousands of facing operations in field conditions without losing accuracy.
