Overview

The DN40 liquid nitrogen pipeline adopts a high vacuum multi-layer insulation form, which has the characteristics of good insulation performance, small cooling loss, energy saving and environmental protection. The position of the liquid supply system can be adjusted according to the on-site situation, and the bending radius of the vacuum hose is small.

Product Details

A vacuum tube is composed of an inner tube, an outer tube, and multiple layers of insulation material, with multiple layers of insulation material composite in the interlayer to reduce radiative heat transfer; And evacuate the interlayer to a high vacuum state to reduce convective heat transfer; The low thermal conductivity material is used to isolate the inner and outer pipes to reduce solid heat transfer, thereby controlling the cooling loss of the inner pipe to a lower limit and fully meeting the long-distance transportation of low-temperature liquids (LOX, LIN, LAr, LH2, LHe, LNG). This is called a high vacuum multi-layer insulated low-temperature liquid transportation pipeline (referred to as a vacuum pipe).

1、 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. Both ends of the vacuum hose are equipped with quick couplings for storage tanks and tank trucks.

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

2、 Vacuum hose material selection

1. Both the inner and outer layers are made of stainless steel metal hoses (304 stainless steel);

2. The interlayer adopts the current specialized multi-layer insulation material;

3. Support with low thermal conductivity;

3、 Application of vacuum hose

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.

4、 Main features

This product adopts a high vacuum multi-layer insulation form, which has the characteristics of good insulation performance, low cooling loss, energy saving and environmental protection.

5、 Technical parameters

6、 What are the advantages of low-temperature vacuum pipelines?

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 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, 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.
