Elastomeric materials are commonly
used in water distribution systems. However,
when these materials are exposed to chloramines, rapid
degradation has been observed. Consequently, it is
important to consider how these materials degrade
(swelling, strength, elongation) when selecting the
appropriate materials to use in water systems.
The purpose of this study was to assess degradation
characteristics and develop life prediction models for
elastomeric materials exposed to chloramines. Based on
the testing, it is clear that elastomer materials have unique
reactions to chloramine-induced degradation. It is therefore
necessary to match the necessary elastomer performance
(elongation, swelling, strength) characteristics with
considerations regarding long-term degradation. By
matching the degradation trends with intended use, elastomeric-
based failures can be reduced in the future.
The results of this research will help water utilities
select more appropriate elastomeric components for use
in their systems. Ultimately, this will benefit the supplier
and the rate payer through better performing
materials and longer design lives. Includes 22 references, tables, figures.
