Originally designed for use in high
pressure cathodic protection systems (flange isolation), the pikotek
VCS has, for over ten years, provided trouble free service by eliminating problems
associated with corrosion in metal piping systems. Conventional wisdom has always regarded
high pressure oil field connections as demanding metal-to-metal sealing integrity. The VCS
revolutionized the concept of integrating non-metallic, non-corrosive sealing components
with a structurally rigid metallic "backbone" in order to achieve an engineered
solution to corrosion resistant high pressure sealing requirements (ANSI 600 class and
higher).Now, the advanced pikotek Flowlok/Firelok flange connection builds upon the legendary service
record of the pikotek VCS by offering even more features and benefits. Specific product
advantages include:
- Elimination of fluid trap in conventional RTJ flange
connections which helps eliminate localized fluid induced corrosion
- Total flange face coverage which seals off all metal flange
surfaces from potentially corrosive media
- Complete electrical isolation/separation for use in cathodic
protection
- Elimination of turbulent flow (pressure drop) and flow
induced erosion in conventional flange connections by sealing flush with the through
conduit bore of the flanges
- Complete cathodic protection of dissimilar metal flange
connections (i.e. carbon steel mated to stainless steel)
- Able to mate with any flange type (i.e. ring type joint-RTJ,
raised face, flat face or any combination of flanges thereof)
- Completely reusable--thus eliminating the costly need to
replace conventional flange gaskets
- Significant design improvement for the minimization of
fugitive emissions (increased sealability)
- Increased structural integrity (compressive and flexural
strength) which yields better resistance to gasket damage due to applied bending moment
- High compressive strength of the retainer reduces the
potential for gasket damage due to over-compression
- Increased fire resistance over all conventional gasket
designs (refer to Firelok specifications)
