The HDPE pre-insulated pipe casing extrusion line is a highly efficient, energy-saving core component of the HDPE casing + PU foam pre-insulated pipe production system. Designed in strict accordance with international standards, it is specifically engineered to manufacture high-quality HDPE casing pipes that serve as the protective outer layer for polyurethane (PU) foam insulated pipes.
Using the vacuum calibration method, the line produces HDPE casing pipes with smooth internal and external surfaces, ensuring long service life, excellent anti-corrosion performance, and strong mechanical properties — all of which contribute to the superior quality of the final pre-insulated pipe.
This fully automatic extrusion line supports high-speed, stable operation, seamlessly integrating into the complete pre-insulated pipe production system. It delivers consistent diameter accuracy, high pressure resistance, and long-term durability, perfectly complementing the PU foam insulation layer to form reliable, high-performance pre-insulated pipes.
Widely applied in district heating, urban pipeline networks, and industrial thermal transmission projects, this line meets global market demands for high-quality casing pipes and overall pre-insulated pipe system performance.
