Tubing, Casing & Drill Pipes Supply

We provide a variety seamless and welded petroleum industry casing, tubing, sucker rods and drill pipes with various end connections. All of our OCTG (Oil Country Tubular Goods) products are manufactured to the API specifications.

Some of the OCTG tubing and casing available for your company’s requirements include:

• General drill pipes, casing pipes and tubing conforming to API standards for oil field and deep well drilling
• 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 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 C955 – 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

13Cr Steel Casing and Tubing-Corrosion Resistant Alloy (CRA) OCTG Pipe

We provide 13% Chromium grades and Corrosion Resistant Alloys (CRA) for oil and gas operations in highly corrosive environments where carbon pipe cannot be used.

APPLICATION:  Deep well environment containing CO2.

INTRODUCTION:  In most conditions when the partial pressure of CO2 is above 30psi, carbon steels present high corrosion rates. Steel grades alloyed with high contents of Chromium (Cr), Molybdenum (Mo) and Nickel (Ni) are able to effectively resist corrosion. 13Cr Steel OCTG Pipe  made with 13% Chromium (13Cr) are the least expensive corrosion-resistant alloy (CRA) tubulars that can be used to combat C0₂ corrision and H₂S environmental cracking without inhibitor treatment. These stainless steel tubulars cost only half as much as duplex stainless steel and one-fourth to one-tenth as much as high-nickel CRA materials. Using 13Cr Steel OCTG Pipe might also be less expensive and more cost-effective than using carbon/low-alloy steel with inhibition. The 13Cr Steel OCTG Pipes are especially attractive for tubing applications in offshore production operations where working space is limited and workover costs are high. Tubulars made with 13% Cr have been widely used in North America, the North Sea, Gulf of Mexico and North Slope of Alaska.
13Cr steel is susceptible to corrosion at high temperature, to sulfidestress cracking (SSC) in moderate to high H₂S environments and to crevice corrosion. Therefore, application of 13Cr Steel OCTG Pipe does require precautions in tubular design, procurement, handling, storage, and field operations.

METALLURGY:  The 13Cr steel and its equivalents are martensitic stainless steels that contain 11.5-14.0 percent chromium.
