Our Thermal Service pipes are the perfect choice for heavy oil applications.
Grades for Thermal applications
Tenaris has created Thermal Service (TH) grades for applications where thermal loads are expected to develop due to working conditions, such as the ones found in Steam Assisted Gravity Drainage (SAGD) or Cyclic Steam Stimulation applications.
This grade is able to evenly accommodate the strains produced by thermal loads in the string and function in high temperature conditions.
