Do not apply gasket
compounds, adhesives, or anti-stick lubricants to the gasket surface.
These compounds may reduce gasket stress leading to excessive
creep relaxation and possible gasket failure.
a Gasket Material
There are many
factors to consider when selecting a gasket material. Please provide
temperature/ pressure range and chemicals
involved in the application.
The gasket must be dry and without oil or
adhesive when installed and should be stored in a dry atmosphere since
the fibers absorb moisture from the air.
The gasket should not be subjected to severe
thermal expansions at the joint assembly.
The required flange loading must be applied at
ambient temperature and must not fall below the required minimum value
over the whole range of service temperature.
