Product Description
Product Description

The one-step polyurethane insulation pipe production line is a highly efficient and automated manufacturing system that integrates multiple processes-such as extruding the outer protective pipe and injecting insulation material-into a single continuous production line. This equipment is widely used in engineering projects requiring thermal insulation, such as district heating pipelines and oil transportation pipelines.
Key advantages include:
Integrated bonding of inner pipe, insulation layer, and outer sheath
Reduced manual operation with improved product quality consistency
Energy-efficient and suitable for large-scale industrial production.
