Non-API seamless OCTG HS150 high strength high ductility deep well casing tubing

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 Deep Well Series shows high strength with good ductility and fracture toughness.

Proprietary steel grades for the deepest wells

Vanforge offers its Deep Well (DW) proprietary steel grades for oil and gas operations demanding very high strength materials with good ductility and fracture toughness. As depth increases a combination of higher pressures and temperatures defines the use of high strength materials.

As yield strength increases, the general trend of carbon steel is to become more brittle. Brittle materials may fail under loads, even those below actual yield strength. We have developed DW grades that achieve this trade-off in addition to high yield strength, good ductility and fracture toughness.

Our DW proprietary steel grades are designed and heat-treated to maximize the combination

of material toughness and high strength.

Our DW Series are available in minimum yield strengths ranging from 135 ksi to 150 ksi. To

determine their material toughness, DW products are subjected to Charpy testing at specific temperatures.
