Suntechmach Hydraulic Butt Fusion Welding Machine, 315-500mm | 9.10kW - SHT500-SHY

Hydraulic 20" HDPE Pipe Butt Fusion Welder

The SuntechMach SHT500-SHY hydraulic butt fusion welding machine is developed for precision welding of large-diameter thermoplastic pipelines used in infrastructure, water transmission, industrial utilities, gas distribution, and power protection projects. Supporting pipe sizes from 315mm up to 500mm (20 Inch), the machine combines a high-capacity hydraulic system with accurate thermal regulation to produce stable, leak-proof joints under demanding site conditions. Its 9.10kW total power output, heavy-duty 4-clamp structure, and industrial-grade hydraulic components make it suitable for continuous operation in field installations and fabrication workshops handling HDPE, PVDF, and MPP piping systems.

The machine operates on a 380V three-phase electrical system and utilizes a precision-controlled PTFE-coated heating plate capable of reaching 270°C for consistent heat distribution across pipe surfaces. The hydraulic unit delivers adjustable pressure up to 16 MPa, allowing operators to maintain proper fusion pressure for thick-wall pipes and high-pressure applications. An integrated dual-channel timer independently records soaking and cooling stages to improve workflow accuracy, while the aluminum machine frame reduces overall weight without sacrificing structural stability during large-pipe alignment and welding operations.

Designed for practical industrial use, the SHT500-SHY includes an electric planing tool equipped with reversible double-edge blades to ensure smooth and perfectly prepared pipe ends before fusion. The machine also features a shock-resistant pressure gauge, low-pressure starting design, isolated heating temperature control, and a multi-position welding structure that simplifies handling of various fittings and pipe configurations in complex working environments.
