1. Characteristics of vacuum insulation hose:
(1) The double-layer stainless steel metal hose is adopted, and the special multilayer insulation composite material is added in the interlayer to maintain the high vacuum state, so the cold insulation effect is good, and the surface of the hose is free of water and frost when it is used.
(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 a special quick connector for storage tank and tank car, which can greatly reduce the liquid vaporization loss in the tank car filling and discharging liquid.
