LCO₂ Vacuum Insulated Pipeline

Keywords：LCO₂ vacuum insulated pipeline, cryogenic CO₂ pipeline, vacuum insulated CO₂ pipe, liquid CO₂ transfer
Category：CO2 Storage and Transportation

The LCO₂ Vacuum Insulated Pipeline is designed for the efficient transfer of liquefied carbon dioxide (LCO₂) at cryogenic temperatures. These pipelines feature a double-wall construction with a vacuum space between the inner and outer pipes, which is filled with multi-layer insulation to minimize heat transfer and maintain the low temperature of the LCO₂. The vacuum insulation significantly reduces evaporation losses and ensures the purity and integrity of the transported gas. These pipelines are widely used in industries such as food and beverage, medical, and chemical processing, where maintaining low temperatures and preventing contamination are crucial.

Product Specifications

Product Overview
The LCO₂ vacuum insulated pipeline (high vacuum multi-layer insulated cryogenic pipeline) is an advanced pipeline system specifically designed for transporting low-temperature liquids, such as liquid oxygen, liquid nitrogen, and liquid argon. It features a dual-pipe structure with high vacuum insulation and multi-layer insulation materials inside, effectively reducing cold loss and serving as an excellent alternative to traditional insulated pipelines, especially suitable for long-distance transportation of cryogenic media.

Product Features

Extremely Low Heat Loss: Compared to traditional insulated pipelines, the heat leakage value of vacuum insulated pipelines is only 0.05 to 0.035 times that of conventional systems, significantly enhancing insulation performance.
Long Service Life: The mechanical service life of vacuum pipelines can reach 10 to 15 years, while the vacuum lifespan can be sustained for 5 to 10 years, reducing maintenance costs.
Multiple Connection Methods: Options include vacuum slip-joint connections, vacuum flange connections, or welded connections for easy installation.
Simple Maintenance: The optimized design allows for straightforward maintenance operations, ensuring stable system performance.

Applications

Industrial Gas Transport: Safely transporting low-temperature liquids such as liquid oxygen, liquid nitrogen, and liquid argon.
Chemical Industry: Providing stable supplies of cryogenic liquids in chemical production processes.
Medical Industry: Used for the transport and storage of medical gases.
Cold Chain Logistics: Ensuring the safe delivery of low-temperature products during cold chain transportation.
Research Institutions: Supplying low-temperature gases for scientific experiments to support various research projects.
