Vacuum Insulated Piping

Product Overview

The Vacuum Insulated Piping is a high-performance pipeline system designed for the transfer of cryogenic liquids, including liquid oxygen, liquid nitrogen, liquid hydrogen, liquid helium, LEG, and LNG. It is widely used in air separation, gas processing, aerospace, electronics, superconductors, chip manufacturing, automation, food & beverage, pharmaceuticals, hospitals, biobanks, rubber, new materials, chemical, and steel industries, as well as in scientific research applications. The system provides efficient thermal insulation, reducing liquid evaporation and ensuring safe and stable cryogenic liquid transfer.

Working Principle

The piping features a high-vacuum, multi-layer, multi-shield insulation design (VI/VJ Piping). It consists of a double-layer stainless steel jacket filled with special multi-layer insulation materials maintained under high vacuum. This design reduces heat leakage to only 0.035–0.05 times that of conventional insulated pipelines, significantly lowering liquid evaporation and improving energy efficiency. The vacuum-insulated structure ensures long-term reliability under extreme low-temperature and high-pressure conditions.

Key Features

• Minimal Heat Loss:Heat leakage is only 3.5–5% of traditional insulation pipelines, effectively reducing cryogenic liquid evaporation.
• Energy and Cost Savings:High-efficiency insulation reduces energy consumption and operating costs.
• Durable Construction:Made from high-quality stainless steel (SUS304), suitable for extreme low temperatures and high-pressure environments.
• High Reliability:Multi-layer shield insulation and high vacuum maintain long-term stable performance.
• Easy Installation:structure ensures safe and secure connection to cryogenic equipment and piping systems.

Applications

• Cryogenic Liquid Transfer:Efficient transfer of liquid oxygen, nitrogen, hydrogen, helium, LEG, LNG, and other low-temperature media.
• Industrial Applications:Air separation, gas processing, chemical, steel, rubber, new materials, and food & beverage industries.
• Research & Laboratory Use:Superconducting systems, chip manufacturing, and low-temperature experimental or research applications.
• Storage & Pipeline Systems:Transfer and distribution of cryogenic liquids in storage tanks, Dewars, cold boxes, and factory pipeline networks.
