St. Louis Pipe and Supply is a leading supplier of any and all types of pipes, no matter the application, including Oil Country Tubular Goods (OCTG). As a leading OCTG tube distributor and OCTG pipe sales company, we supply seamless casing, tubing and drill pipes used for on-shore and off-shore oil and gas exploration, drilling and extraction, and other pipes and connectors.
If you are looking for an OCTG tube distributor, here are some of the casings and tubes we regularly supply:
- API C90 – an API controlled yield strength grade (25.4 HRC maximum) typically 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 C955 – same strength range as T95 and U. S. Steel C95, but without a hardness requirement; generally not used in sour wells
- API H40 tubing/pipe – general purpose pipes conforming to API specification 5CT
- API J55 general purpose pipes for 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 tubing/pipes 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 P110 – typically 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
- 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
