Downhole Applications
Mechanically Lined Tubulars
Our Mechanically Lined Tubulars (OCTG) combine the strength of a carbon steel outer layer with a Corrosion Resistant Alloy (CRA) lining and premium connections featuring metal-to-metal gas-tight sealing.
Specifications
Diameter
4″ – 20″
Grade Selection
K55, L80, T95 and P110 *13Cr/22Cr Hybrids
Host Tubular
API 5CT
CRA Selection

Our Solution Offers:
Mechanically Lined Tubulars (MLT) are used in downhole applications across geothermal, CCUS, and water injection wells. With a CRA liner, MLTs offer corrosion protection at higher temperatures than non-metallic options like GRE.
In CCUS, where 25Cr solid CRA is common, Cladtek’s MLT matches or exceeds corrosion performance while offering easier handling, higher toughness, and strength from the carbon steel backing. MLT is also more cost-efficient—especially at larger diameters—and allows safer cleaning and inspection. It can be combined with solid CRA in critical zones like perforations.
Our Solution Offers:
Mechanically Lined Tubulars (MLT) provide durable corrosion protection for downhole applications in sectors like geothermal, CCUS, and water injection, with CRA liners that withstand high temperatures beyond non-metallic alternatives like GRE. Cladtek’s MLT offers similar performance to 25Cr solid CRA tubulars commonly used in CO₂ capture, but at a more competitive price. Cost efficiency scales with diameter, making MLT more economical as pipe size increases. Additionally, MLT’s resilience allows for cleaning and inspection with minimal risk of damage, ensuring reliable, low-maintenance performance.
