Shengji vacuum insulated tubing & casing steam injection provides a perfect solution for oilfield heavy oil recovery process. More heat can enter oil layer via the insulated tubing & casing steam injection. The steam at the bottom of the well can be dry, increasing heavy oil output. This also prevents any damage on casing mantle caused by the high temperature deformation, and at the same time increase the casing service lifespan.

Shengji vacuum insulated tubing & casing uses water-based fiber cloth material with a three grade vacuum pump equipment, automatic welding machine and MT. These guarantees a high degree of vacuum level that meets the insulation grades D and E.

These vacuum insulated tubing & casing use an effective getter to ensure the tubing insulation grade do not decrease after a long time of outdoor storage. Shengji vacuum insulated tubing & casing are reusable. They retain desired insulation properties after being used several times. Shengji people are dedicated to the development of new products. Our products constitute almost 80% market share in Shengli Oilfield VIT market at the moment.
