The vacuum hose
Vacuum hose technical design
● vacuum hose can be adjusted according to the situation of the liquid supply system, the bending radius of the vacuum hose is small
● good holding time, when the use of the hose surface without water and frost
● both ends of the vacuum hose are equipped with storage tank and tank car special quick joint
● customers with special needs to customize the special structure of the vacuum adiabatic hose vacuum hose application
● Main application of vacuum hose: tank filling and draining liquid;Conversion of hard connection between tank and low temperature liquid equipment;Conversion between hard vacuum tube and low temperature liquid equipment.
● vacuum hose application industry: industrial gas, medicine, biology, electronics, aviation, automobile, restaurant, beverage industry, transport liquid nitrogen (LN), liquid argon (LAr), liquid oxygen (LOX), liquefied natural gas (LNG).
Vacuum hose material selection
● The inner and outer layers are special quality stainless steel metal hose (SUS304)
● the current advanced special layer insulation material is used in the interlayer
● low thermal conductivity
