Product Description

Non-API seamless OCTG HS95TT high collapse resistant deep oil 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 High Collapse Series (HC) exhibit higher collapse resistance than that determined for API 5CT/ISO 11960 products.

 

Proprietary steel Grade for high-pressure service

Vanforge provides the High Collapse Series of proprietary steel grades for oil and gas wells where high external pressures are anticipated and collapse resistances higher than API are needed.

 

In addition to uniform external pressures, the reservoir can exert high pressures due to ground

movements or saline strata, subjecting pipes to extreme localized external pressure.

 

Our HC Series is available in minimum yield strengths ranging from 80 ksi to 140 ksi. These products have higher collapse resistance than that determined for API 5CT/ISO 11960 products.

 

As an additional requirement they can be manufactured with controlled Yield Strength in order to enhance the Internal Yield Pressure.

 

As an alternative to the HC series, we also manufacture the Improved Collapse grades. They are an excellent cost-benefit solution for less severe applications.

 

IC grades are API steel grades with improved performance. They are available in minimum

yield strength of 80 ksi, 110 ksi and 125 ksi. As an additional requirement they can be manufactured with controlled Yield Strength in order to enhance the Internal Yield Pressure.

 

The collapse pressure of a pipe is related to the stiffness or rigidity of the cross section area along the pipe length. Dimensional and mechanical properties determine a true high collapse proprietary product. We pay strict attention to these variables when manufacturing our High Collapse Series.

 

Dimensional properties

The dimensional properties of a high collapse pipe depend on three factors: external diameter to wall thickness ratio, ovality and eccentricity. Low ovality, low eccentricity and the maximum wall thickness for the maximum allowed pipe weight will give the best dimensional conditions for collapse resistance.

 

Mechanical properties

The mechanical properties that determine high collapse are yield strength and residual stresses. Strict control of the heat treatment process to ensure optimum yield strength distribution and minimal compressive residual stresses will lead to the maximum collapse properties of the pipe.

 

Our High Collapse Series consistently outperforms API TR 5C3 & ISO/TR 10400 collapse resistance for API steel grades.

 

 

High collapse and sour service

The design of our High Collapse & Sour Service grades is based on the development of carbon low alloy steels. The manufacturing process is strictly controlled from steelmaking through rolling and heat treatment.

 

Grades to withstand high pressures in corrosive environments

Vanforge has developed the High Collapse & Sour Service steel grades to meet the needs of oil and gas operations in environments characterized by a combination of high external pressure and the probability of Sulfide Stress Cracking due to the presence of H2S

.

We offer our High Collapse & Sour Service grades in a range of yield strengths from 80 ksi to 125 ksi.

 

In addition to uniform external pressures, high pressures can be exerted by reservoir, ground movements or saline strata, subjecting pipes to extreme localized external pressure.

 

Hydrogen sulfide dissolved in water may lead to Sulfide Stress Cracking. The factors that activate the cracking phenomena include: high stress state, high acidity levels, H2S partial pressure and a susceptible microstructure.

 

The design of the High Collapse & Sour Service grades is based on the development of carbon low alloy steels. The manufacturing process is strictly controlled from steelmaking through rolling and heat treatment.

 

Our state-of-the-art manufacturing facilities provide strict cleanliness, physical and metallurgical controls as well as tight dimensional controls to ensure outstanding resistance to hydrogen Sulfide Stress Cracking under high external pressures.
