“…The current pipeline standard API (American Petroleum Institute) Spec 5L 23 stipulates that the roundness of pipe should not exceed 1.5% of the diameter (0.75% when the pipe is used offshore). To effectively reduce the ovality of the pipeline, the pipe calibration methods mainly include expanding process, [24][25][26][27][28][29][30] compression process, 25,[31][32][33][34][35] over-bending setting round by mold press type method, 36 internal expansion over bending and calibration (IEOBC) process, 37 the symmetrical threeroller setting round process, [38][39][40] the process of continuous and synchronous calibration of roundness and straightness by three rollers, [41][42][43][44][45][46] and so on. Zhai et al 37 built the intelligent control system of IEOBC process, which is mainly used for pipe end rounding .…”

Submarine pipeline is an important part of deep-sea and ultra-deep-sea oil and gas development. In the cold forming process of longitudinal submerged arc welded (LSAW) pipe, the JCO manufacturing process is one of the key forming technologies for manufacturing submarine pipeline. The main problem encountered by submarine pipelines in offshore oil and gas transportation is insufficient pipeline collapse pressure, which leads to pipeline collapse and shortens the service life of the pipeline. Therefore, the analysis of the JCO manufacturing process is of great significance to improve the collapse resistance of pipelines. In this paper, the development and research status of the JCOE/JCOC manufacturing process are reviewed. The stress, contact, and deformation of the plate are symmetrical in the JCOE/JCOC manufacturing process. The effects of expanding and compression on pipe collapse performance in the JCO manufacturing process are summarized. The asymmetric factors can reduce the collapse performance of the pipeline. Compared with expanding, compression can effectively reduce the ovality of pipe and strengthen the compression performance of pipe, to improve the collapse performance of pipe; finally, the JCOE/JCOC manufacturing process and collapse resistance of submarine pipeline is summarized and prospected.
