OCTG PRODUCTS

FEATURES

As a contributing member of the American Petroleum Institute (API) since 1925, U. S. Steel Tubular Products manufactures a comprehensive range of monogrammed API 5CT OCTG grades.

API H40 is a general purpose pipe manufactured to API specification 5CT.

API J55 is a general purpose pipe manufactured to API specification 5CT. Similar to K55 except the minimum tensile strength is lower.

API K55 is a general purpose pipe manufactured to API specification 5CT. Usually, this grade is most often used in casing applications.

API N80 Type 1 is a lower cost alternative to standard Quench and Tempered API N80 (walls less than 0.500 inch). Charpy V-notch impact test absorbed energy results meet API SR16 and are lower than quenched-and-tempered N80.

API N80Q is a general purpose pipe manufactured to API specification 5CT using a quench and temper process.

API L80 is manufactured to API specification 5CT. This is a controlled yield strength material with a hardness testing requirement. L80 is often used in wells with sour (H2S) environments.

API C90 is an API controlled yield strength grade generally for use in sour condensate wells. Extensive hardness testing is required along with Sulfide Stress Corrosion Cracking (SSCC) testing per NACE Standard TM-0177, Method A. The minimum threshold stress required is 80% of specified minimum yield strength.

API R95 is an API grade with the same strength range as T95 and USS C95, but without a hardness requirement. This grade is not generally considered for use in sour condensate wells since no hardness restrictions or testing are required and no Sulfide Stress Corrosion Cracking (SSCC) testing is required.

PI T95 is an API controlled yield strength grade, the same as API C95 and USS C95. Generally for use in sour condensate wells. Extensive hardness testing is required along with SSCC testing per NACE Standard TM-0177, Method A. The minimum threshold stress required is 80% of specified minimum yield strength.

API P110 is an API grade for general use in deep wells. This grade is not generally considered suitable for sour condensate wells.

API C110 is a controlled yield strength grade generally used in deeper sour condensate wells. SSCC testing is required for each heat to meet a threshold stress of 85% of specified minimum yield strength.

API Q125 is an API grade for deep well service, not generally for use in sour condensate wells. Quadrant hardness testing is required without any specified limits other than the variation between readings. Impact testing is required for each heat and/or lot. NDT inspection is required with two methods of inspection; typically EMI and UT are performed on this product.

FEATURES

U. S. Steel Tubular Products offers enhanced versions of standard API 5CT grades for use in applications where improvements to performance properties such as Burst, Collapse and Tension Capacity can help optimize casing designs.

P110 RY P110 RY is a controlled yield strength product that meets all inspection, testing and dimensional requirements of API P110.
Yield strength is restricted to the bottom half of the acceptable range for API P110 (i.e. – 110,000 to 125,000 psi).

P110 HC is a product with a demonstrated collapse resistance exceeding the minimum values for standard API P110.

P110 HP is a product with the highest demonstrated collapse resistance exceeding the minimum internal yield pressure for standard API P110.

Q125 HC is manufactured to API specification 5CT. This is a product with a demonstrated collapse resistance exceeding the minimum values for standard API Q125.

Q125 HP is a product with a higher demonstrated collapse resistance, exceeding the minimum internal yield pressure for standard API Q125.

Q125 XHP is a product with the highest demonstrated collapse resistance, exceeding the minimum internal yield pressure for standard API Q125.

FEATURES

In addition to the existing family of API 5CT grades, U. S. Steel Tubular Products manufactures proprietary OCTG grades. These grades come with tailored specifications aimed at minimizing costs, reducing lead times, and meeting distinct performance criteria for sour service applications.

USS N80N is a lower cost, non-heat treated alternative to standard Quench and Tempered API N80 (for walls less than 0.500 inch). USS N80N meets all the requirements of API N80 with the exception of Charpy V-notch impact toughness.

USS C90 is a proprietary, restricted yield strength U. S. Steel grade for use in sour condensate wells. Resistance to sulfide stress cracking is achieved by precise controls of chemical composition, heat treatment, and hardness levels.Inspection requirements and dimensional tolerances are in accordance with API 5CT for grade C90. Performance properties are the same as for API grade C90. Hardness testing is conducted as required for API C90, except for frequency (casing and non-upset tubing – first and last and every tenth joint in between; upset tubing – first and last and every 25th joint in between). To reduce order lead time, sulfide stress corrosion cracking (SSCC) testing is not required for every order. If required by the customer, SSCC testing can be performed to U. S. Steel Standard Mill Practice P-1004 (NACE Standard TM-0177, Method A) with a guaranteed minimum threshold stress of 85% of specified minimum yield strength.

USS C95 is a proprietary restricted yield strength U. S. Steel grade for use in sour condensate wells. Resistance to sulfide stress cracking is achieved by precise controls of chemical composition, heat treatment and hardness levels.Inspection requirements and dimensional tolerances are in accordance with API 5CT for grade T95. Performance properties are the same as for API grade T95. Hardness testing is conducted as required for API T95, except for frequency (casing and non-upset tubing first and last and every tenth joint in between) upset tubing (first and last and every 25th joint between). To reduce order lead-time, sulfide stress corrosion cracking (SSCC) testing is not required for every order. If required by the customer, SSCC testing can be performed to U. S. Steel Standard Mill Practice P-1004 (NACE Standard TM-0177, Method A) with a guaranteed minimum threshold stress of 85% of specified minimum yield strength.

NACE (SSC), Method A testing is specified at a threshold stress of 85% of specified minimum yield strength.

USS RYS110 is a proprietary restricted yield strength U. S. Steel grade for use in sour condensate wells. Resistance to sulfide stress cracking is achieved by precise controls of chemical composition, heat treatment, and hardness levels. Inspection requirements and dimensional tolerances are in accordance with API 5CT for grade P110 PSL 1. Performance properties are the same as for API grade C110. One quadrant through-wall hardness testing is performed at a frequency of two per 100 pieces per heat lot.
