Hydraulic butt welding machines for PE, PP and PVDF plastic pipes Hydraulic butt welding machines for polyethylene pipes The machine combines high quality, ergonomics, professional and precise assembly. The bed is made of very robust , while not heavy metal, reinforced with stiffening ribs. This protects it from deformation, kinking during vibrations arising from constant pipe facing. The station is equipped with large diameter hydraulic cylinders, which provides a smooth controlled movement of the clamps along the rod, without surges, and better retention of the compression pressure at the right moment.
