Continuous Polyurethane (PU) Foam Insulation Plastic Pipe Extruder
This equipment is specifically designed for producing small-diameter polyurethane (PU) insulation pipes, with a common pipe diameter range of 48-630mm.
This equipment can continuously complete multiple key processes of insulation pipe production on the same production line, including extruding outer protective pipes and injecting insulation materials, ensuring high production efficiency. It is primarily used for manufacturing polyurethane insulation pipes, capable of closely bonding the inner pipe, insulation layer, and outer protective layer of the insulation pipe. Its high degree of automation effectively reduces manual operation steps, thereby enhancing the stability of product quality. This equipment is widely applied in pipeline construction projects requiring insulation, such as heating pipelines and oil pipelines.
