1. Characteristics of vacuum insulation hose:
(1) The double-layer stainless steel metal hose is used, and the special multi-
layer insulation composite material is added in the interlayer to keep the high
vacuum state, so the cold insulation effffect is good, and the appearance of
the hose is free of water and frost when in use.
(2) The bending radius is small, easy to use, and the length can be
determined according to the user's requirements.
(3) It can be connected with vacuum pipe.
(4) Both ends of the vacuum hose are equipped with special quick
connectors for storage tank and tank car, which can greatly reduce the
vaporization loss of liquid in the tank car.
