Eastern United States - Testing Report by Corrosion Testing Laboratories:

A series of fused on HDPE reducers (reducing 42” to 30”) were used in a pipeline that carried raw water to a cooling process in a manufacturing operation.  The reducer section failed after  11 months in service.   During laboratory examination, it was found that one of the fusion joints had separated “semi-circumferentially” due to “improper technique during fusion of the two parts”.1
