LCO2 Vacuum Insulated Pipeline

Product Overview

The LCO₂ vacuum insulated pipeline is a cryogenic transfer system designed using high-vacuum multi-layer insulation technology. It is specifically used for the efficient transportation of cryogenic liquids such as liquid oxygen, liquid nitrogen, liquid argon, and liquid carbon dioxide.

The pipeline adopts a double-layer structure, forming a high-vacuum environment in the interlayer and incorporating multi-layer insulation materials, which significantly reduces cold loss. It serves as a highly efficient alternative to conventional insulated pipelines under cryogenic conditions.

This system is particularly suitable for medium- to long-distance cryogenic liquid transfer, offering both energy efficiency and reliable operation.

Working Principle

The pipeline is based on high-vacuum multi-layer insulation principles. A stable high-vacuum environment is established between the inner and outer pipes, combined with multiple layers of reflective insulation materials.

This design effectively suppresses heat transfer through conduction, convection, and radiation, thereby significantly reducing heat leakage.

During operation, cryogenic liquids maintain a stable low-temperature state while flowing through the pipeline, minimizing vaporization loss. A reliable sealing structure ensures long-term vacuum stability, while optimized structural design guarantees continuous and stable performance under complex working conditions.
