Superior Performance for Downhole Applications

Cladtek’s Mechanically Lined Tubulars (MLT) combine the strength of a carbon steel outer layer with the corrosion resistance of a CRA lining, offering a cost-effective, durable, and high-performance alternative to solid CRA tubulars. Designed with premium connections featuring metal-to-metal gas-tight sealing, CRA-MLT provides enhanced corrosion protection while maintaining ease of handling and installation.

Applications of CRA Mechanically Lined Tubulars

Mechanically Lined Tubulars are widely used in downhole applications across multiple industries, providing superior corrosion resistance, high-temperature tolerance, and long-term reliability.

Geothermal & Water Injection Wells

  • The CRA liner protects against corrosive fluids while withstanding extreme temperatures beyond the range of non-metallic liners such as GRE.
  • Ideal for large-bore gas wells and water injection applications, ensuring durability in high-pressure environments.

Carbon Capture, Utilisation & Storage (CCUS) and Carbon Capture & Storage (CCS)

  • Traditional CO₂ capture relies on 25Cr solid CRA tubulars—Cladtek’s MLT offers comparable performance at a lower cost.
  • MLT technology is scalable, with increasing cost benefits as diameter size increases.
  • Unlike GRE alternatives, MLT allows for cleaning and inspection interventions with minimal risk of damage.
