Zhuoda Yuntong Low Temperature Liquid Vacuum Pipe/Vacuum Hard Pipe

In recent years, with the development of low-temperature cryogenic liquids（LOXTheLINTheLArTheLH2TheLHeTheLNG）Widely used in various production fields of society, traditional pipeline equipment stacking insulation methods (such as perlite insulation, rock wool insulation, polyurethane insulation, etc.) suffer significant economic losses due to high cold loss and high gasification rate of low-temperature liquids.

1. We divide the pipeline into sections according to the pipeline diagram, and each section of the pipeline adopts high vacuum multi-layer winding insulation, 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 and technical indicatorsadvancedStable performance, safe and reliable, 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 pipeline is carefully designed, strictly manufactured, and connected reasonably to reduce cold loss to a lower level. The low-temperature liquid passes through the pipeline24No frosting or sweating in hours, the product is suitable for transportationLNGTheLO2TheLN2TheLArEtc., widely used andLNGAutomobile refueling stations, steel mills, metallurgy, chemical industry, food, large-scale air separation liquid transportation, natural gas engineering.

（5） 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 smaller than that of foamed polyurethane100More than twice)

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 smaller than that of stacked insulated pipelines with the same nominal diameter10More than twice;

8. Beautiful appearance design

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.Customized vacuum insulated hoses with special structural forms for customers with special needs
