The polyurethane (PUR) spraying polyethylene (PE) wrapping pre-insulated pipe production line is designed for manufacturing high-performance prefabricated direct-buried thermal insulation pipes, widely used in district heating, cooling systems, and crude oil transportation. This automated line ensures superior insulation, durability, and cost-efficiency for underground pipeline networks.
The pre-insulated pipe consists of three layers:
High Automation: Streamlined production with minimal manual intervention.
Customizable Thickness: Adjustable PUR foam (30-100mm) and PE casing (4.5-10mm).
Superior Insulation: Uniform foam density eliminates air gaps.
Cost-Effective: Reduced material waste and energy consumption.
