Product Description Vacuum Insulated TubingVacuum Insulated Tubing (VIT) is designed to develop oil and gas fields located in the most challenging oil and gas production conditions.For example, Pre-stressed Vacuum Insulated Tubing (VIT) replaces oil tubing for heavy oil recovery by steam injection to improve project economics.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. 1.Vacuum insulated tubing & casing are reusable;2.Reduces heat loss ensuring optimal steam quality being injected into the oil formation;3.Minimizes heat stress on well casing and cement mantle, decreases unwanted annulus pressure;4.Improves well life cycle cost and avoids failure due to well integrity issues;5.Optimized cyclic steam stimulation cycles for better overall project economics;6.Important technology for the economic production of deeper heavy oil formations.
