Product Description

Vacuum Insulated Tubing

 

 

 

Structure Characteristics
It is a double - concentric - tube string structure. The annular space between the two tubes is filled with

insulating materials, inert gases, or evacuated to a vacuum state. When steam injection is used to extract

heavy oil, the use of insulated tubing can reduce heat loss and increase the steam dryness. Prestressed

insulated tubing can overcome the expansion and contraction deformation caused by temperature changes.

Generally, its insulation life can reach 30 huff - and - puff cycles.
The Performance of Product

1.Vacuum prestressed insulated tubing uses prestressing compensation technology to ensure its reliable

mechanical properties at high temperature.

2.In order to save cost, the grade of steel can be used in L80,P110,N80,J55 etc.

3.The seal ring is filled with getter / aerogels etc, the product has good thermal insulation performance, it

plays an important role in preventing heat loss in insulated tubing.

4.Reduces the heat loss, certainly the steam quality and the depth of steam injection can be increased.

5.The use of geothermal resources, reducing the cost of electricity.

6.Widely used in the field of high temperature steam injection in heavy oil, Low temperature cold recovery

of high pour point oil, Insulation of oil pipeline, Geothermal well etc.
