As the use of chloramination becomes more widely
practiced, some utility managers may question
whether long-term exposure to chloramines will
compromise the functioning and/or shorten the life of
their rubber gasketed ductile-iron pipe joints.
The paper discusses why special elastomers for
ductile-iron pipe joints are not required in water systems
using chloramination for disinfection. Specifically,
the effect of chloramines on nitriles, styrene butadiene,
neoprenes, ethylene-propylene, and fluorocarbons is
examined. The author concludes that the effect of
chloramine on elastomers is application-specific, but
that chloramination will not compromise the life of
elastomer gaskets supplied with push-on and mechanical
joint ductile-iron pipe. Includes 11 references, tables, figures.
