TMK-Kaztrubprom specializes in the production of high-tight threaded premium connections of Casing and Tubing for the oil and gas industry.

TMK-Kaztrubprom is a part of "TMK", one of the largest holdings of the metallurgical industry in Russia.

Receiving advanced developments from scientific and technical centers around the world, and being a plant with a high-technology cycle, TMK-Kaztrubprom produces pipes in the territory of the Republic of Kazakhstan.

The production is carried out using modern German equipment, the line is fully automated, it includes a full production cycle: from the stage of preparation of pipes to weighing processes, marking and packaging of finished products. The enterprise's capacities allow producing more than 40 thousand tons of finished pipes per year.

The main assortment of "TMK-Kaztrubprom" - tubing and casing for the oil and gas industry, including ones with premium threaded connections. These pipes are used for all technological operations associated with the construction of oil and gas wells.

Premium connection for Casing
TMK UP CENTUM

Third generation premium threaded and coupled connection. Unique design for quick assembly and sealability under the most severe well conditions. Tested and validated per API 5C5 CAL IV under 100% tension and 100% compression. Available globally with dope free GreenWell technology.

Range: 4-1/2 – 13-5/8’’ / 114,3 – 346,08 mm

Unique Feature
• Sealability envelope equal to 100% of pipe body strength
• Fastest assembling premium connection

Thread Profile
• Hooked thread profile with negative load flank eliminates thread jump-out
• Close fitting thread minimizes movement within the connection and transfer of load onto the seal and shoulder under compression
• Thread root and crest are parallel to the pipe axis which results in deep and easy stabbing
• Optimized thread profile offers robust galling resistance
• Reduced cross threading
• Increased bending capacity

Metal-to-Metal Seal
• Sphere and sphere gas-tight seal
• Tested and validated under API 5C5 CAL IV at 100% of pipe body strength

Shoulder
• Unique shoulder design resists compressive loads through controlled elastic deformation due to its length
• Large contact area at the pin nose and shoulder interface provide the connection with extreme torque and compression capacity
Additional sealing barrier
