LCO2 Cryogenic Hose

Product Overview

The LCO₂ cryogenic vacuum insulated flexible hose is a high-performance flexible pipeline designed for the transfer of cryogenic liquids. It is suitable for ultra-low temperature media such as liquid nitrogen, liquid oxygen, liquid argon, and liquid carbon dioxide.

The hose adopts a double-layer stainless steel structure, with multiple layers of high-efficiency insulation composite materials filled between the inner and outer pipes and maintained under a high-vacuum condition. This design significantly reduces heat transfer.

Combining excellent thermal insulation performance with flexibility, the hose is ideal for connections and transfer applications under complex operating conditions. It is widely used in cryogenic storage, transportation, and industrial transfer systems.

Working Principle

The hose is based on high-vacuum multi-layer insulation technology. A stable vacuum layer is formed between the double-layer stainless steel pipes, combined with multiple layers of insulation materials to effectively suppress heat transfer caused by conduction, convection, and radiation.

This significantly reduces cold loss and ensures that the cryogenic liquid maintains a stable low temperature during transfer, minimizing vaporization.

The system features a reliable sealing structure and dedicated vacuum maintenance technology to ensure long-term stable operation. At the same time, the flexible structural design allows the hose to maintain excellent insulation performance even during bending and installation.
