Large Diameter Seals

Large diameter seals for extreme service conditions

In addition to our extensive offering of spring-energized seals, bonded seals, and composite seals, CDI is a manufacturer of high-performance, large diameter, polymeric sealing solutions. The materials used in our large diameter seals are selected for extreme service conditions.

Our material scientists create solutions using in-house proprietary compounds and develop specialized customer blends to achieve performance objectives, that are:

  • NORSOK M-710 approved
  • API 6A- Appendix F Tested
  • Designed for HPHT environments
  • Fit for high differential pressures
  • Sour service (H2S) tolerant
  • Resistant to chemically aggressive environments
  • RGD and ED resistant
  • Lubricated and dry wear resistant (dynamic seals)

BY LAND AND BY SEA

Suited for subsea systems as well as land-based drilling and production operations, we leverage one of the industry’s broadest material portfolios. It boasts a wide range of elastomers, thermoplastics, and high-performance proprietary compounds.

We develop an array of large diameter sealing components and geometries, such as:

  • OptiSeal® Components
  • V-Rings
  • U-Type Seals
  • Valve Seats
  • Excluders
  • Piston Rings
  • Custom Components
