Abstract
The burst pressure from full scale burst tests on GRP pipes with integral GRP flanges is compared with the predicted failure pressure using glass content analysis and material strength data for the different composite layers. Two theoretical models were used to predict the failure load; a simple analytical solution for a plain pipe and a detailed finite element stress analysis including the flange geometry and loading. In both cases, the failure pressure was generally overestimated and it is suggested that this may be due to difficulties in construction resulting in the composite layers close to the flange having inferior strength as compared with a basic pipe with the same glass content.
