The Energy Saving HDPE Pipe Extrusion Machine is a high-precision, fully automatic HDPE jacket pipe extrusion line purpose-built to manufacture protective casing pipe for PU foam pre-insulated pipeline systems. At its core is a precision vacuum calibration table that sizes every pipe while the HDPE is still molten. This is the key technology that separates this pipe extrusion production line from standard extrusion equipment, and it ensures a tight, reliable bond with the polyurethane foam insulation layer.

This HDPE plastic pipe extrusion line is widely applied in district heating networks, chilled water distribution systems, and buried thermal insulation pipeline projects across Russia, Central Asia, the Middle East, and Africa. It offers 7 standard models. One flexible platform serves both high-temperature heating pipelines (up to 120°C) and low-temperature chilled water pipelines.

Paired with dust-free planetary cutting, the line removes plastic dust and cutting debris at the source and keeps the workshop clean from extrusion to final cutting. All finished HDPE jacket pipe complies with international standards EN253, EN14241, and GB/T29047. It delivers accurate dimensional control, a smooth inner and outer surface, and long-term mechanical protection for buried pre-insulated pipe.

Matched seamlessly with the HDPE casing + PU foam pre-insulated pipe production line, this PE pipe extruder machine sustains a stable output of 250-1350 kg/h. PLC computerized control keeps extrusion parameters stable, lowers energy consumption, and reduces scrap, which gives manufacturers a competitive plastic pipe extrusion line price per meter of jacket pipe. With more than 20 years of R&D and manufacturing experience, we have installed 389+ sets of HDPE jacket pipe extrusion lines in more than 60 countries, earning the trust of pre-insulated pipe manufacturers and EPC contractors worldwide.
