Non-API seamless OCTG HS80H heavy oil well casing tubing for thermal service
Vanforge provides a complete range of steel grades for all kinds of oil and gas operations.
API steel Grades
Vanforge supply all API steel grades including all the additional Supplementary Requirements (SR) and/or Product Specification Levels (PSLs).
Proprietary steel Grades
We supply steel grades with performance properties that surpass those indicated by the API.
Grades with enhanced performance properties
Vanforge provides the following proprietary steel grades for superior mechanical properties:
High collapse
Deep well
Low temperature
High ductility
Thermal service
Grades for corrosive environments
To improve the corrosion resistance for the demanding conditions of particular oil and gas wells, Vanforge has developed a variety of proprietary steel grades that extend the life span of pipe products reducing corrosion rates:
Sour service
High collapse & Sour service
Critical service
Corrosion Resistant Alloys
Our Thermal Service pipes are the perfect choice for heavy oil applications.
Grades for Thermal applications
Vanforge has created Thermal Service 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.
These grades are able to evenly accommodate the strains produced by thermal loads in the string and function in high temperature conditions.
Our TN 55TH and TN 80TH will additionally comply with improved toughness requirements.
