This Continuous PU Foaming Insulation Pipe Jacket Extruder is a fully automated production line designed for manufacturing polyurethane (PU) insulated plastic pipes. It is suitable for producing insulation pipes with diameters ranging from 48mm to 630mm, commonly used in heating systems, oil pipelines, and other thermal insulation applications.

The machine integrates multiple processes into one continuous production line, including outer protective pipe extrusion, epoxy coating, adhesive application, PE jacketing, and PU foaming, ensuring high efficiency and consistent product quality. The inner pipe, insulation layer, and outer protective layer are tightly bonded together, providing excellent thermal insulation and durability.

With a high level of automation, this equipment significantly reduces manual labor and improves production stability and safety. It is ideal for modern pipeline insulation projects that require efficient and reliable manufacturing solutions.

• Suitable for pipe diameter range: 48-630mm
• Fully automatic production line for high efficiency and stable output
• Integrated process: coating, bonding, extruding, and foaming in one line
• High-quality polyurethane (PU) foam insulation
• Ensures tight bonding between inner pipe, insulation layer, and outer PE jacket
• Energy-saving and environmentally friendly design
• Widely used in district heating, oil transportation, chemical, and industrial piping systems
