Vaccum insluation tubing & casing

Sanjack Group has 23-year’s experience in manufacturing tubing and casing. Sanjack Group set up thread upsetting production line  in 1999 and designed Sanjack Group premium thread in 2011. The product quality is stable and reliable. The annual production reaches 100,000 tons. The products has been provided in the U.S.A, Canada, Venezuela, India Kazakhstan and etc.

Vacuum Insulated Tubular is one of the essential equipment for the steam injection thick oil recovery. More heat can enter the oil layer by the insulated tubing steam injection.  Therefore the steam at the bottom of the well can be drier, so that the increased production of the thick oil can be realized.

Prevent the damage of casing and cement sheath caused by the high temperature deformation, and increase the casing lifetime at the same time.

Sanjack has 10-years’ experience in manufacturing vacuum tubing and casing. The product quality is stable and reliable.

Sanjack owned 2 seamless steel pipe production lines, 3 VIT tubing production lines, 7 tubing & casing processing lines and 2 steel pipe upsetting lines. The annual production reaches 1 million meters.

The products have been provided in many oilfields of China and exported to Canada, Oman, Kazakhstan and etc. In shengli Oilfield, market share of SJ Vacuum Insulated Tubular exceed 80% in 3 years.
