Recently, the intelligent inspection data of one natural gas transmitting pipeline showed that lots of the blistering was found in the pipe inner surface. In this paper, the method of finite element analysis was carried out to simulate and calculate the effect of blistering to the pipe strength. The results show that the max vonmises stress of the pipe with blistering was close to the yield strength and the max vonmises stress of the pipe increased with the increase of the press in the blistering. The minimum safety factor in the pipe with blistering was 0.99 which was reduced by the blistering. The sulfide stress corrosion (SSCC) and the manufacturing technology of hot rolling compound accelerated the growth of the blistering in the pipe. |
