Vacuum metal hose

Vacuum insulation pipe：

1. The double-layer stainless steel metal hose is used, and *multi-layer insulating composite materials are added in the interlayer to maintain a high vacuum state, so the cold insulation effect is good, and the hose surface is free of water and frost during use.

2. The bending radius is small, convenient to use, and the length can be determined according to user requirements.

3. It can be connected with vacuum pipe.

4. Both ends of the vacuum hose are equipped with storage tank and tank car  quick connector, which can greatly reduce the liquid vaporization loss in the liquid filled and discharged by the tank car.
