Some of the OCTG casing tubing available for your requirements include:
General casing tubing conforming to API standards for oil field and deep well drilling

• API H40 casing tubing – general purpose pipes conforming to API specification 5CT
• API J55 general purpose pipes for casing tubing applications, similar to specification K55 with lower minimum tensile strength conforming to API specification 5CT
• API K55 general purpose pipes used primarily in casings conforming to API specification 5CT
• API L80 casing tubing conforming to API specification 5CT with a controlled yield strength with hardness test requirement of 23 HRC maximum; usually used in wells with sour (H2S) environments or deep sour wells
• API N80 or N80 Q&T (Quench and Tempered) – general purpose pipe manufactured to API specification 5CT
• API Normalized N80 – lower-cost alternative to standard Q&T N80; pipe walls less than 0.500 inch; inspections, testing and dimensions are in accordance with API 5CT for grade N80. Charpy v-notch impact test absorbed energy results conform to API SR16 and are lower Q&T N80
• API C90 – an API controlled yield strength grade (25.4 HRC maximum) generally used in sour condensate wells; with required extensive hardness testing, SSCC testing per NACE Standard TM-0177-Method A; minimum threshold stress required is 80% of specified minimum yield strength
• API C95 – same strength range as T95 and U. S. Steel C95, but without a hardness requirement; generally not used in sour wells
• API T95 – API controlled yield strength grade (25.4 HRC maximum), the same as API C95 and U. S. Steel C95; generally for use in sour condensate wells; extensive hardness testing is required including SSCC testing per NACE Standard TM-0177-Method A; minimum threshold stress required is 80% of specified minimum yield strength
• API P110 – generally used in deep wells; this grade is not suitable for most sour condensate wells
• API Q125 – API grade for deep well service, generally not for use in sour condensate wells; quadrant hardness testing is required (no specified hardness limits other than the variation between readings); impact testing required for each heat and/or lot; typically EMI and UT NDT inspections are required
