Reinforcement and Repair Pressure Pipeline With CFRP

Abstract:

In order to ensure the safety of production, a new method for strengthening pipe with carbon fiber reinforced polymer sheet is introduced. The experimental research on the effect of this method has also been done. In the experiment, the pipe that wrapped with one and two layers of CFRP sheets respectively are tested. And the relation between the hoop strain in the tested pipe and the internal water pressure is given according to the experiments. The results show that it can be a substantial increase in the bearing capacity of the pipes. The construction of this method is simple and a short period is required; so it not affect the normal operation of generating unit. It has a good practical value in the production practice.
