Why ductile iron couplings on stainless steel pipes works ...

Jan 15, 2020  The use of Victaulic couplings with ductile iron housings on stainless steel pipe is common practice when pipe material selection is based on compatibility with the fluid media and where the risk of external corrosion is low. Due to the design of the coupling housings and elastomer gasket, the housings will never contact the internal fluid media.
