Pekotek VCSThe Pikotek VCS gasket is a high reliability gasket used for both insulating and general sealing purposes in Very Critical Services. The gasket has a proven track record of integrity in aggressive sealing situations. The VCS is suitable in all services up to and including ANSI 2500# and API 10,000# classes. The VCS is designed for service where the cost of gasket failure cannot be tolerated. The VCS gasket consists of a PTFE (Teflon) spring-energized face seal, or an elastomeric o-ring, seated in an insulating laminate, which is permanently bonded to a high-strength metal gasket core. Due to its unique pressure activated sealing mechanism, the gasket requires far less bolt stress to seal than any other gasket. The VCS gasket inner diameter is exactly matched to the flange bore to eliminate turbulent flow and flange face erosion/corrosion. The seal elements are replaceable in the reusable gasket retainer.

OPTIONS and DATA

  • Seals and isolates all pressure ratings through ANSI 2500# class and API 10,000# psi service
  • Designed to withstand corrosive environments, including high concentrations of CO2, H2S, produced water and aggressive inhibitors
  • Good electrical isolation properties for cathodic protection
  • Pressure-activated seals provide high confidence sealing, eliminates costly leaks and provides a solution for fugitive emissions
  • Mitigates galvanic corrosion in dissimilar metal flanges
  • Can mate mismatched RTJ with raised-face flanges
  • Works in Ring Joint Flanges, reducing fluid entrapment, flow induced erosion and media induced corrosion between flanges
  • Gasket is self-aligning and centering; quick to install and no special tools are required
  • Prevents turbulent flow at flanged connections
  • High-strength laminate material resists failure due to excessive compression
  • Available to match any flange specification (ANSI, ASME, API, MSS, BS, DIN, AS and others)
