PE Heat Insulation Pipe Extrusion Line
Product Overview
The PE Heat Insulation Pipe Extrusion Line, offered by OmegaPack, manufactures large-diameter PE jacket pipes used in directly buried polyurethane-insulated steel pipelines. The production line creates a three-layer structure: an outer PE pipe, a rigid polyurethane foam insulation layer (density 60–80 kg/m³), and an inner carrier pipe (steel). Pipes can withstand temperatures ranging from 120 °C up to 180 °C, making them ideal for central heating, hot/cold water, air conditioning, and industrial insulation applications.
Large diameters up to Ø2,000 mm are supported, with vacuum calibration ensuring smooth surface finish, stable foam insulation, and consistent wall thickness. High-efficiency single-screw extruders and Siemens PLC automation provide continuous, reliable operation with bright surface quality and minimal labor.
Applications
Used as insulated outer jackets in:
District heating and cooling (PU-insulated piping)
Hot/cold water supply systems and industrial pipelines
Indoor/outdoor heating, air conditioning, chemical, and pharmaceutical applications
Performance Benefits
Produces uniform insulated jacket pipes with excellent thermal and mechanical properties
Ensures stable continuous production with stainless steel molds and precise calibration
Reduces labor and waste with automated haul-off and chipless planetary cutting systems
Enhances durability and quality through vacuum calibration versus inflation-based methods
Supports downstream PU-injection and pipeline assembly for pre-insulated systems
