28. 28. CECOS University Department of Mechanical Engineering Conclusions In this project Strain gauges are used to detect the compression and tension in long pipe during bending. The proposed technique is a type of nondestructive tests that allows the examination of pipeline structural health without causing any damage to the material. The gathered information provide valuable information regarding strain. 28
