Neoprene Faced Phenolic Gaskets
Neoprene Faced Phenolic Gaskets have been usedas standard flat” isolating gaskets in the oil and gas industries
for many years. Soft neoprene rubber sheets are factory applied to
both sides of a laminated phenolic retainer providing an effective
sealing surface. The temperature limit of these gaskets is
approximately +175 F. (+80 C.).
Application of Neoprene Faced Phenolic Gaskets
- To limit the extent and cost of cathodic protection current to only
those pipes that need to be protected from the main cathodic
- To electrically "split up" long pipelines into distinctive cathodic
- To isolate a pipeline to ensure that cathodic protection or stray
electricity currents do not cause increased corrosion, or cause a
- To isolate piping systems where dissimilar metals are present
- To eliminate static loading charge transfer in discharge or loading
operations at oil storage terminals
Type E (Full Face Gasket)
This gasket kit provides complete protection of both flange faces.
The gasket has same outside diameter of flanges. This feature will
prevent collection of foreign matter between the flange faces to
ensure complete cathodic isolation.
Type F (Ring Gasket)
This gasket is manufactured to fit only the raised face surface of
the flanges. Outside diameter of the gasket is designed to be
slightly less than the inside diameter of the bolt circle. It is
recommended that the flanges be wrapped to prevent foreign material
from "shorting out" the flanges.
