Vacuum Insulted Tubing (VIT)

Made to exacting standards in both China and Canada, our line of Vacuum Insulated Tubes provide the heavy oil sector a cost effective assist to steam injection enhanced production activities. Available in multiple size and grade combinations, VIT tubes provide an alternative to other more expensive tertiary recovery methods.

  • VIT dramatically reduces heat flow from the inner surface of the inner tube to the outer surface of the outer tube.
  • VIT is designed to address all three methods of heat transfer: radiation,conduction and convection.
  • VIT is composed of outer pipe, inner pipe, insulation, coupling, seal ring and insulated liner. The insulation applies multilayer aluminum foil and glass fiber.
  • VIT Getter: Long-life vacuum integrity ensured through the use of getters inside the vacuum. It is a metal alloy, which absorbs molecular gases, primarily hydrogen.
  • VIT is composed of an outer threaded tube, with an inner tube welded inside.
  • VIT annulus space vacuum in known as “super insulated technology” by many countries all over the world.

The VIT Advantage

Reduces:

  • SOR – Steam to Oil ratio
  • Steam rate, energy costs, and operating temperature
  • Heat stress on casing and deformation
  • Circulation period for production
  • Greenhouse emissions
  • Casing diameter and need for premium connections in certain applications
  • Workouts to remove blockage wax (paraffin)

Improves:

  • Steam control at the toe of well and heat loss to surroundings
  • Protection for cementing

ROI and ROE is tangible and positive
