Abstract

Because of the inherent structure of welded pipelines, the Seam Weld can be a potential source for initiation and propagation of crack that can eventually lead to failure of the structure. Due to the critical conditions in the welding region, the investigation of failure energy in Gas Transportation Pipeline is very important for engineers and line designers. In this paper, the Three-Point Bending Test (according to the standard specimen of drop-weight tear test) was performed quasi-statically on the Seam Weld pipe and base metal of spiral Seam Weld pipe of API X65 Steel from which force diagrams were extracted. The presence of sudden load drops in the force-displacement diagram of the specimen in the weld indicated the inhomogeneous structure of the weld. The diagrams of force-displacement, yield and ultimate force, amount of steady crack growth and Fracture Energy of the metal and Seam Weld specimens including initiation and propagation energy of crack were investigated and compared. Also, the ratio of the force drop to the ultimate force at the same displacement rate was investigated. The results showed that in Seam Weld compared to the base metal specimen, the yield force was higher and the ultimate force, the amount of steady crack, initiation and propagation energy of crack were lower. In addition, the lower ratio of force to ultimate force (at the same displacement) in the base metal also indicated a high resistance of the base to the crack propagation.
