Product Description
A PE Vacuum Calibration Insulation Pipeline Making Machine is a full production line for making pre-insulated PE jacket pipes with precise dimensions and high quality. It's widely used in modern pipeline production - especially where energy efficiency and long service life are required.
These machines produce HDPE outer jacket pipes for pre-insulated pipelines. The typical three-layer structure of pre-insulated pipe is: Qingdao Huashida Machinery Co., Ltd.
Inner Carrier Pipe: Steel or other metal that carries 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 high durability, excellent insulation, corrosion resistance, and reliable performance in trenchless and direct burial applications.
