HDPE Vacuum Calibration Insulation Pipe Making Machine is a complete production line designed for manufacturing pre-insulated PE jacket pipes with precise dimensions and high quality. It is widely used in modern pipeline production, particularly where energy efficiency and long service life are required.
These machines produce HDPE jacket pipes for pre insulated pipeline systems. The typical three-layer structure of a pre-insulated pipe consists of:
Inner carrier pipe: Steel or other metal that carries the fluid (hot water, steam, oil, etc.)
Middle insulation layer: Rigid polyurethane foam (PUF) for thermal insulation
Outer PE jacket pipe: High-density polyethylene protective shell
The result is a pipe with high durability, excellent thermal insulation, corrosion resistance, and reliable performance - suitable for both trenchless and direct burial applications.
