The One-Step pre-insulated Pipe Production Line is an advanced, fully integrated manufacturing system designed for the continuous production of high-performance insulated pipelines used in district heating, oil & gas transportation, and underground thermal networks. This system adopts one-step continuous forming technology, where the carrier pipe, polyurethane foam insulation, and outer HDPE jacket are combined in a single synchronized process. Compared to traditional multi-step production, this technology significantly improves efficiency, reduces labor, and ensures superior bonding quality between layers. The production line is suitable for manufacturing pre-insulated pipes with diameters ranging from 30mm to 500mm (or customized), meeting international standards for thermal insulation and pipeline protection.
This production line is engineered to produce three-layer insulated pipe structures, consisting of:
1- Inner Pipe (Steel or Plastic Carrier Pipe)
Responsible for fluid transportation (hot water, oil, gas, etc.)
2- Middle Layer (Rigid Polyurethane Foam)
Provides excellent thermal insulation with low thermal conductivity and high compressive strength.
3- Outer Layer (HDPE Jacket Pipe)
Protects the pipeline from moisture, corrosion, and mechanical damage, especially in underground environments.
