Overview
The main applications of vacuum hoses are: tank truck flushing and discharging liquids; Hard connection conversion between storage tanks and low-temperature liquid equipment; The conversion between vacuum hard tubes and low-temperature liquid equipment is used for conveying pipes on and off LNG terminals and LNG unloading, as well as for low-temperature environments of superconducting cables. Zhuoda Yuntong Liquid Oxygen Pipeline/Low Temperature Liquid Pipeline
Product Details
（1） Characteristics of vacuum hose:
Design of Vacuum Hose Technology
1.The vacuum hose can adjust the position of the liquid supply system according to the on-site situation, and the bending radius of the vacuum hose is small
2.Good cold insulation effect, the surface of the hose does not freeze or frost during use.
3.Quick couplings for storage tanks and tank trucks at both ends of the vacuum hose
4.Customized vacuum insulated hoses with special structural forms for customers with special needs
Vacuum hose material selection
1.Both the inner and outer layers are made of stainless steel metal hoses（304Stainless steel)
2.The interlayer adopts the current specialized multi-layer insulation material
3.Support with low thermal conductivity
（2） Application of vacuum hose
The main applications of vacuum hoses are: tank truck flushing and discharging liquids; Hard connection conversion between storage tanks and low-temperature liquid equipment; Conversion between vacuum hard tubes and low-temperature liquid equipment, used forLNGOn the dock, disembarking, andLNGThe unloading conveyor pipe is used for low-temperature environments such as superconducting cables.
