Insulated Tubing for Steam Injection

We manufacture insulated tubing with high thermal efficiency to conduct fluids with or without couplings in many diameters.

Our High thermal efficiency insulated tubing for steam injection are designed and manufactured to ensure that the thermal energy of the steam is maintained along the entire length of the column until it reaches the head of the oil reservoir, thereby reducing its viscosity.

  • High thermal efficiency nanoporous insulation.
  • Automated circumferential welds.
  • Heat treatment for stress relief.
  • USS Buttress and USS Buttress Modified threads.

Etinov’s insulated steam injection tubing can be supplied with USS Buttress or Buttress Modified threads, with or without insulated insert. The insulated insert is a metal ring filled with an insulating composite material of high thermal efficiency on its surroundings. The inner diameter of the insulated insert has the same diameter as the inner pipe. The length is designed to provide minimal clearance when both tubes and couplings are coupled at maximum torque. The insulated insert is supplied in one piece and installed with the coupling during the assembly of the column in the well.
