PLC Controlled Pre-Insulated Pipe Production Line with Vacuum Calibration and Planetary Cutting HDPE Jacket Pipe Extrusion Line

The HDPE Jacket Pipe Extrusion Line is specially designed to manufacture high-quality polyethylene outer jackets for polyurethane (PU) pre-insulated pipes used in underground heating and thermal insulation systems.

The HDPE outer jacket provides excellent waterproofing, impact resistance, and mechanical protection, helping maintain the integrity and service life of the insulation layer.

Huashida offers advanced extrusion technology with a vacuum calibration system to ensure accurate dimensions, uniform wall thickness, and stable production. The line features an intelligent PLC control system, reliable operation, high production efficiency, and energy-saving performance, helping manufacturers improve productivity and reduce operating costs.

• Adopts next-generation solid-liquid separation screw technology (industry-leading in China).
