Hi Animesh,
The use of the gasket that you describe is far in excess of the requirements for water service. So there is nothing wrong with its selection other than the waste of money for over specification.
There are other materials that have been developed to replace CAF. Klinger manufacture an equivalent. For low pressure service (<700kPa) fabric reinforced neoprene or natural rubber is commonly used in building services, mining and water and astewater industries.

Dear Friends
In our new project we are planning to repeat the existing plant layout/ PDS
model. earlier we have used CAF gasket with AWWA std flange(flat face) in
the water service.
Now, as the CAF gasket is not environment & Health friendly we are planing
to replace it with Spiral wound graphile filled gasket keeping the flange
as AWWA -C207 class D std - Flat face only, Serrated spiral finish
What you people suggest, what problem you envisage using this combination.
Is any std says about this combination.
Pls note: AWWA says to use full face gasket, no where it is given that we
can not use the Spiral wound gasket
