HDPE Jacket Pipe Casing Extrusion Line with Dust-Free Cutting for Pre-Insulated Pipe
This HDPE Jacket Pipe Casing Extrusion Line is a high-performance system engineered to produce durable protective casings for PUR (Polyurethane) foam pre-insulated pipe systems. Featuring dust-free planetary cutting technology alongside state-of-the-art vacuum calibration, this production line eliminates plastic dust and debris during the cutting stage - keeping the production environment clean while ensuring casing pipes meet rigorous international standards for thermal insulation and mechanical protection.
By integrating seamlessly into the (HDPE casing + PU foam) manufacturing workflow, our HDPE casing extrusion line delivers high-speed output while maintaining energy efficiency. The resulting pre-insulated pipe casing features superior anti-corrosion properties and high-precision diameter accuracy across a 110-2200mm pipe diameter range, essential for long-term underground and industrial service.
