Abstract

In the countries with natural gas, repair of gas transmission pips is a problem. In this study, the epoxy composite with single wall carbon nanotubes reinforcements as patch was used and the von Mises stress distribution was determined. For this purpose, the tubular steel with thickness and length 6 mm 1.5 m was simulated in ANSYS SOFTWARE at both ends of the pipe patched-epoxy composite single-walled carbon nanotubes with reinforcing particles ratios 0.01, 0.03, 0.05, 0.07, 0.1, 0.13 and 0.15 were applied. Then, according to the true values of internal pressure and external pressure, the stress of gas pipe distribution on the patch was determined. Von Mises stress results showed that, carbon nanotubes 0.01 times the maximum repair patch has 0.19 MPa von Mises stress is the maximum that occurred in the casing without patches that 1.48 Mpa is, much less. It was also found to increase the percentage of carbon nanotube to 0.15, von Mises stress to the maximum reaches 0.43 MPa. As a result, it can be stated that the nanocomposite patch greater ease in pipes, can be improved tensile properties are repaired areas. As well as increasing the percentage of nanotubes in composites, von Mises stress increases the maximum in the elderly.
