Stainless steel LNG vacuum pipeline

1、 Stainless steel LNG vacuum pipelineMain features:

Stainless steel vacuum pipelines adopt a high vacuum multi-layer insulation form, which has the characteristics of good insulation performance, small cooling loss, energy conservation and environmental protection.

2、 Briefly describe

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)

3、 What are the advantages of stainless steel LNG 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.
