Abstract
- This paper discussed the aging behaviour of Kevlar fibre reinforced flexible pipe subjected to long-term monotonic internal pressure. Multi-group of pipe internal pressure tests that last for 10,000 h were conducted. The pressure-time curves of each test samples were collected. Two typical failure modes of the samples were specified. Linear regression analysis of the original pressure-time data was conducted and expression between characteristic pressurePand service timeT, which is capable to provide fast evaluation of pipe qualification, was presented. Based on suitable selection of safety factor, the design pressures under different service time were calibrated. Analysis shows that the LTHS50/LTHS10 ratio meets the requirements claimed by ASTM D2992, thus these calibrated design pressures can be used for engineering practice. [ABSTRACT FROM AUTHOR]
