Vacume Insulated Tubing

Vacuum Insulated Tubing (VIT) Are Tubing With High Heat Insulation Performance. With 20 Years Of Production   Experience, Freet Is One Of The Leading Companies In  Producing VIT.

VIT Is Composed Of Host String, Thermo Case, Coupling, Sealing Ring And Liner Pipe. The Insulated Tubing Adopts  Double-Walled Enclosed Welded Structure. The Inner Tube Is Treated With Pre-Stressing Process During Welding. There Are Multilayer Insulation Structures In The Annulus Space As Well As Getter In The Thermo Case That Can Reduce Heat Transfer, Energy Loss By Convection And Radiation, And Avert Hydrogen Explosion And Prolong The Service Life.

The Vacuum Insulated Tubing Operates Under The Condition That The Temperature Of Heat Carrier Is Less Than 350℃ The Insulated Tubing Mainly Applies To Steam Thermal Recovery Well With "Huff And Puff" And "Steam Drive" As Well As Heavy Oil Well With "Integration Of  Production And Injection".
