355mm Hydraulic Semi Automatic PE Pipe Butt Fusion Welding Machine
This 355mm hot melt welding machine is heavy‑load hydraulic semi‑automatic butt fusion equipment for medium‑large‑diameter PE, HDPE and PVDF pipes. The machine frame is built with thickened welded steel to bear the load of heavy‑wall pipes and absorb vibration from rough field working conditions. The reinforced clamping blocks increase contact area to lock pipes tightly, preventing slippage under high pressing pressure. The anti‑corrosion surface finish provides long‑lasting protection against rain, dust and frequent temperature changes on construction sites.
It adopts high‑stability digital constant‑temperature control system. The temperature error is within plus or minus 5 centigrade and the maximum heating temperature is 270 centigrade. The large‑size heating plate ensures thorough heat penetration for thick pipe end faces, effectively lowering the risk of partial under‑melting and internal hidden welding defects. The optimized hydraulic system supplies balanced thrust to keep pipe ends concentric during heating and pressure‑holding phases.
This equipment is widely used for urban secondary water supply networks, municipal sewage branch pipelines and large‑area farmland irrigation projects. It can complete multiple continuous welding cycles and creates high‑strength joints that meet routine engineering inspection requirements.
