“…The FE model is described in the following section. Since the simulation of roll forming is well described in literature, e.g., in Han et al [ 18 , 42 ], the focus is placed on the transition from the roll forming to the welding simulation, as well as on modeling the HFI welding.…”

“…Furthermore, Kim et al [ 15 ] used the FEM to minimize the deformation of the band edge during roll forming. Many scientific publications have proven that the geometry of the open seam tube can be predicted correctly by means of FEM [ 16 , 17 , 18 , 19 ]. This also holds for residual stresses, which arise in the tube during roll forming, as shown by Bauer et al [ 20 ].…”

This paper presents a fully coupled three-dimensional finite element model for the simulation of a tube manufacturing process consisting of roll forming and high-frequency induction welding. The multiphysics model is based on the dual mesh method. Thus, the electromagnetic field, the temperature field, the elasto-plastic deformation of the weld bead, and the phase transformations within the material can be simulated for a moving tube without remeshing. A comparison with measurements shows that the geometry of the welded tube and the weld bead, the force on the squeeze rolls, the temperature along the band edges, and the hardness distribution within the heat-affected zone can be simulated realistically.

“…49 An analytical approach using finite element method is proposed to simulate the roll-forming, sizing processes, and collapse performance in manufacturing of ERW pipe made of API 5L X70 steel. 50 UOE pipeline can produce the pipeline with high roundness, and its ovality can be controlled at 0.15%-0.35%. Although its ovality is low, its collapse ability is weaker than that of seamless pipes of the same steel grade.…”

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.

“…Electric resistance welded (ERW) pipes have excellent productivity and economic efficiency because they are manufactured in a single continuous process from beginning to end. Thus, demand has increased for ERW pipes as the material of choice for deep-water offshore pipelines [1][2][3]. Due to extremely high pressure in deep-water applications, the collapse pressure governs the design of offshore pipelines.…”

Plastic deformation during the manufacture process of electric resistance welded (ERW) pipe determines the stress–strain relationship of the steel pipe, which affects the collapse pressure of offshore pipelines. To track the deformation history of the pipe, the entire process was simulated via finite element analysis using a solid element. A material model that considered both the Bauschinger effect and strain hardening was adopted. Various sizes of pipe cross-sections were simulated. As greater compression was applied during the sizing process, the strain hardening effect became more significant, so that the compressive yield strength was increased in the circumferential direction. The strain hardening effect was most prominent for a smaller diameter-to-thickness ratio (D/t), so that an increase in the collapse pressure could be obtained with a larger sizing ratio. Therefore, current design criteria for the collapse pressure recommended by Det Norske Verita (DNV) and API could be enhanced for a smaller D/t to consider the strain hardening effect during the sizing process.
