摘要

CIPP Liners have been proven to be a successful method for renovating deteriorated gravity pipelines.rnThe key to the success of this process has been the ability of installers to design liners that withstand the test of time.rnThese liners are designed using models that predict the long term mechanical properties of the constructed liner,rnconsidering all loads, present and future.rnIn North America, the most common method for predicting the long term flexural properties is described in ASTMrnMethod D2990, Standard Test Methods for Tensile, Compressive, and Flexural Creep and Creep Rupture of Plastics.rnThis paper is a study of the results obtained under this method using various CIPP thermoset resins and variousrnfiberglass reinforced liner bag materials and how the results affect the final design of a CIPP liner. The effects ofrnloading on the samples and the effects of different resins with varying initial mechanical properties will be studied.rnAlso, the test variable that can be set at different values based on the ASTM will be discussed. Calculations donernwith the results of several settings of the test variable and the impact the results have on the liner’s design thicknessrnwill be illustrated.
