摘要

本研究对内压下破裂管道的修复进行了研究。为此，对破裂管道进行了实验测试，以找出失效压力。在外表面上施加了一条纵向裂纹，该裂纹切割了65%的管道厚度。碳纤维增强聚合物已被用于修复该系统。此外，还建立了一个有限元模型来估计未修复管道的失效压力。结果表明，未修复管道的失效压力与腐蚀管道标准预测的失效压力相同，但修复系统的失效压力低于腐蚀管道标准的预测结果。

Experimental study on repair of cracked pipe under internal pressure

Repair of cracked pipeline under internal pressure has been investigated in the present study. To this aim, an experimental test has been done on the cracked pipeline to find failure pressure. A longitudinal crack that cut 65% thickness of pipe has been applied on the external surface. Carbon fiber reinforced polymer has been used to repair the system. Additionally, a finite element model has been developed to estimate failure pressure of the unrepaired pipes. The results show that the failure pressure in unrepaired pipes is identical to the failure pressure predicted by the standards for corroded pipes, however, the failure pressure of repaired system is lower than the predicted results of standard for corroded pipelines.
