Description

Vacuum Insulated Tubing is used for injecting high-temperature and high-pressure vapor to oil producing formation. It combined by main pipe string, heat insulation layer, coupling, sealing ring and lining pipe. It made prestress treatment to internal pipe during welding, interlayer of internal and external pipe filled multi-layer heat insulating material, which can prevent heat loss produced by conducting, convention and radiation effectively. It can used for injection of 350℃ high-temperature vapor. Connection thread adopts API buttress thread.
