The stress relieving heat treatment affected the tensile properties of API 5L X65 pipe manufactured to meet sour service requirements. The decrease in yield and tensile strength for specimens sampled from pipe body (Figure 13a), and tensile strength for specimens sampled from girth weld (Figure 14) confirms that the heat treatment is not indicated for this type of material. For girth weld tests, the specimen fracture occurred at base metal (Figure 15), showing that the weld strength was not strongly affected by heat treatment and that the pipe base material is susceptible to stress relieving heat treatment. Figure 13b) shows that the tensile strength of the SAW longitudinal weld was affected by heat treatment but, in this case, it is above the minimum value required by API 5L.IBP1184 13 Welding and Heat Treatment of Heavy Wall API 5L ...
