Rubber in Acidic Enviroment
Rubber in Acidic Enviroment
(OP)
We are evaluating the use of "un-restrained coupling" joint in under ground oily waste water piping.
This coupling joint is equipped with internal rubber gasket, which should seal the external of piping end.
My Questions are:
1) Is this type of joint reliable in under ground oily waste water system?
2) The rubber gasket will get in tough with oily waste water, which may contain acidic solution such H2S. Can this rubber gasket withstand this acidic environment?
Thanks all

Another source to consider---Red Valve Company has a very informative 'Chemical to Elastomer Guide' which I have used for reference purposes for many years.
