Vacuum hose’s features

1. Adopts double layers stainless metal hose. The interlayer uses multi-layer insulation composite materials and keeps the high vacuum station which is helpful to keep cool. The appearance of hose is non-water and non-frost when the hose is used.
2. Small bending radius; convenient to use; the length can be changed according to your demand.
3. Can be connected with vacuum pipeline.
4. The both ends of vacuum hose is matched with quick coupling special for tank and tanker, which can reduce the liquefied lost of tanker’s filling liquid drainage.

Vacuum pipeline’s features According to the pipeline map to make in segment. Each segment adopts vacuum multi-layer winding insulation with good efficiency of cool preservation. Between the segments, we adopts wielding link on-site or flange link. Install and maintain conveniently. Save large amount of installation workload and installation fees. Adopts the logical compensation structure with advanced technical index, steady performance. It is save and reliable. Aesthetic appearance and long use life. Pipeline is processed scientifically. The surface is smooth, beautiful and anti-eroded with the skillful link; prolong the pipeline’s use life.
