The Effects of OCTG Connection Swaging and Stress Relieving on SSC Resistance
Swaging/expansion and subsequent stress relieving are common methods of manufacture for many of the premium integral joint connections used for Oil Country Tubular Goods (OCTG). This paper discusses how the sulfide stress cracking (SSC) resistance of high strength alloy steels utilizes for OCTG are affected by the swaging/expansion and stress relieving process. Details are provided on the effects of cold working on other various tubular properties. Recommendations are provided on proper stress relieving techniques to assure no deterioration of SSC resistance of high strength sour service tubulars.
