Suntechmach Hydraulic Butt Fusion Welding Machine, 250-400mm | 7.4kW - SHT400SHY

PPRC & HDPE Butt Fusion Welder (16 Inch)

Constructing major municipal water mains, gas distribution pipelines, and high-voltage underground power grids requires fusing massive 16-inch thermoplastic conduits. This level of utility engineering demands a heavy-duty system capable of delivering immense, uninterrupted thermal and mechanical force. The SuntechMach SHT400-SHY is a specialized, 3-Phase Plastic pipe welding machine engineered precisely for these extreme-duty applications. Accommodating a demanding working range from 250mm to 400mm (16 Inch), this machine harnesses a powerful 7.4kW (7400W) electrical core operating on 380V. It provides civil contractors with the raw thermal capacity needed to securely join specialized high-density industrial plastics, including standard water-grade HDPE, highly chemical-resistant PVDF, and high-voltage MPP cable protection pipes.

Handling large-diameter, thick-walled piping requires much more than just heat; it necessitates flawless, sustained pressure management to prevent joint failure. Utilizing an advanced heavy-duty hydraulic station, this machine generates a commanding, adjustable pressure range from 0 to 16 MPa. Relying on this robust hydraulic thrust ensures that heavy pipe segments are pressed together with absolute concentricity across the rigid, cast aluminum 4-Clamp Jaws framework. To guarantee structural integrity during the fusion cycle, the system is equipped with an independent two-channel timer that strictly tracks both the heating and cooling phases, alongside a shock-proof pressure dial that provides crisp, vibration-free readings even in active field trenches.

Designed specifically for unpredictable outdoor worksites, the SHT400-SHY operates seamlessly in ambient temperatures ranging from -5°C up to 40°C. Preparation is highly automated and safe; the motorized electric planer features reversible, double cutting-edge blades for a perfectly flat facing finish, protected by a safety limit switch that strictly prevents motor activation unless locked in the working position. By combining overwhelming hydraulic force with intelligent safety mechanisms, this 383 kg industrial welder guarantees perfectly sealed, leak-proof joints that can endure decades of intense subterranean pressure.
