API 5CT T95 Pipes

API 5CT T95 casing and tubing is intended for deep sour wells where the material must handle high mechanical loads while resisting sulphide stress cracking. Amardeep Steel supplies T95 in the sizes and specifications required for demanding oilfield applications. Among the Group 2 sour-service grades, T95 provides a higher strength level than API 5CT C90 pipes and API 5CT L80 pipes. For other oilfield and process requirements, our range of seamless pipes and tubes covers multiple grades and specifications.

Each order can be supplied with mill test certificates, hardness survey records, and sulphide stress cracking test reports for the relevant heat, supporting material traceability and sour-service verification.

What Are API 5CT T95 Pipes?

API 5CT T95 is a restricted yield grade in Group 2. Its yield strength must sit between 655 and 758 MPa and its hardness may not exceed 25.4 HRC. Like C90, it has to pass a mandatory sulphide stress cracking test before it can be supplied.

Drilling engineers pick T95 for deep, high pressure sour wells where the casing or tubing has to carry a heavy load and still resist hydrogen sulphide.

Why T95 Combines Strength With Sour Resistance

T95 uses a chromium molybdenum chemistry with a minimum chromium content, tight sulphur and phosphorus limits and the highest minimum tempering temperature of any API 5CT grade. This heavy tempering gives a fine, even structure that holds a higher strength without becoming brittle in sour conditions.

API 5CT T95 Colour Code

T95 pipe carries one silver band, and every length is stencilled with the grade, size, weight and heat number.

SSC Testing of API 5CT T95 Pipes

Each heat of T95 is tested for sulphide stress cracking to NACE TM0177 Method A, with specimens loaded to at least 80 percent of the specified minimum yield strength in an H2S saturated solution. Passing this test is a condition of supply.

Applications of API 5CT T95 Casing and Tubing

• Production casing in deep, high pressure sour wells
• Production tubing in sour gas condensate fields
• Intermediate casing through sour zones
• Offshore sour gas developments

Testing and Documentation

Every order of API 5CT T95 pipe goes through the checks below at our testing facility or approved third party labs.

• Heat and product chemical analysis
• Tensile test for yield, tensile strength and elongation
• Hardness survey across the wall section
• Charpy V-notch impact test
• Sulphide stress cracking test to NACE TM0177 Method A
• Hydrostatic test on every length
• Full length drift test
• Ultrasonic or electromagnetic inspection of the pipe body
• Thread gauging, visual and dimensional inspection
• Third party inspection on request

Mill test certificates are issued to EN 10204 3.1, with 3.2 available on request. You can view our approvals on the certificates page.

Packing and Marking

Each length is stencilled with the manufacturer name, API 5CT, size, weight, grade, connection and heat number, and carries the API colour band for its grade. Threads are protected with steel or plastic thread protectors, and pipes are bundled or loaded loose with spacers depending on size. Read more about our packing and despatch process.
