Overview

The main applications of vacuum hoses are: tank truck flushing and discharging liquids; Hard connection conversion between storage tanks and low-temperature liquid equipment; The conversion between vacuum hard tubes and low-temperature liquid equipment is used for conveying pipes on and off LNG terminals and LNG unloading, as well as for low-temperature environments of superconducting cables.

Product Details

In recent years, with the widespread application of low-temperature cryogenic liquids (LOX, LIN, LAr, LH2, LHe, LNG) in various production fields of society, traditional pipeline equipment stacking insulation methods (such as perlite insulation, rock wool insulation, polyurethane insulation, etc.) have suffered significant economic losses due to high cold loss and gasification rate of low-temperature liquids.

1. We divide the pipeline into sections according to the pipeline diagram, and use high vacuum multi-layer winding insulation for each section of the pipeline, which has good cold insulation effect. The pipelines are connected by on-site butt welding or flange connection, which is easy to install and maintain, and can save a lot of on-site installation workload and installation costs.

2. Adopting a reasonable compensation structure, advanced technical indicators, stable performance, safety and reliability, beautiful appearance, long service life. The pipeline has been scientifically treated, with a smooth and beautiful surface, corrosion resistance, and clever connections, which can greatly extend the service life of the pipeline.

　　
Our company's high vacuum insulated low-temperature liquid transportation pipelines are carefully designed, strictly manufactured, and reasonably connected to achieve lower cold loss. The low-temperature liquid passes through the pipeline for 24 hours without frosting or sweating. The products are suitable for transporting LNG, LO2, LN2, LAr, etc. They are widely used in LNG vehicle refueling stations, steel mills, metallurgy, chemical industry, food, large-scale air separation liquid transportation, and natural gas engineering.

The characteristics of the high vacuum multi-layer insulated pipeline produced by our company are:

1. The pipeline interlayer adopts a high vacuum multi-layer insulation structure, which makes the convective heat transfer of gas very small and negligible;

2. The effective thermal conductivity of high vacuum insulation materials is small (more than 100 times smaller than that of foamed polyurethane)

3. Segmented production of low-temperature insulation pipes for easy installation and maintenance;

4. The overall pipeline structure design is reasonable, the material control is strict, the component processing technology is efficient, and the pipeline has a long service life;

5. According to user needs, high vacuum multi-layer insulated low-temperature shut-off valves, check valves, emergency shut-off valves, filters, safety venting systems, and other components can be added to low-temperature insulated pipelines.

6. The pipeline is equipped with a process compensator, ensuring structural safety and stability.

7. The heat leakage of high vacuum low-temperature insulated pipelines is more than 10 times smaller than that of stacked insulated pipelines with the same nominal diameter;

8. The appearance design is beautiful.

Design of Vacuum Hose Technology

1. The vacuum hose can adjust the position of the liquid supply system according to the on-site situation, and the bending radius of the vacuum hose is small;

2. Good cold insulation effect, the surface of the hose does not freeze or frost during use;

3. Quick couplings for storage tanks and tank trucks at both ends of the vacuum hose;

4. Customers with special needs can customize vacuum insulated hoses with special structural forms;
