Numerical Simulation and Experimental Confirmation of a Bimetallic Pipe Forming Process

Abstract

Most oil and gas is transported by pipeline, and corrosion causes a great threat to the service life of the pipeline; bimetallic pipe, which combines the advantages of good mechanical properties, good corrosion resistance, and relatively low price, is a good choice for high-pressure and corrosion-resistant pipe, but its manufacturing process and stress distribution are more complex than single metal pipe. JCO is a widely used cold forming method for pipes which is named by the shape of the plate in the forming process, i.e. J-shape, C-shape and O-shape, and the forming process is an important parameter that determines the level of imperfections and residual stresses in a pipe, and residual tensile stress will accelerate corrosion failure of the pipe. In this study, the three-dimensional (3D) finite element method (FEM) is used to simulate the pre-bending and JCO forming process of a 2205/X65 bimetallic pipe. The model and the simulated results are validated by digital image correlation (DIC) experimental and the opening width of the formed pipe billet, respectively. The influence factors of the stresses are studied. Further, a two-dimensional (2D) model is established to study the characteristics of bimetallic plate bending and the stress distribution at the interface of different materials, and the results are compared with that of three-dimensional model.

Effect of Functionally Graded Material (FGM) Interlayer in Metal Additive Manufacturing of Inconel-Stainless Bimetallic Structure by Laser Melting Deposition (LMD) and Wire Arc Additive Manufacturing (WAAM)

“…A bimetallic structure is a composite material in which two different metals are combined to obtain the advantages of different properties such as the thermo-physical, mechanical, electrical, optical, and corrosion/oxidation resistance properties of the two materials [ 1 ]. The development of these structures offers numerous advantages over a single material and allows for a wide range of applications [ 2 , 3 , 4 , 5 ]. Additive manufacturing (AM) can fabricate bimetallic structures entirely using multiple metallic materials, and these can also be fabricated using metallic parts prefabricated by conventional manufacturing techniques as a substrate.…”

Modeling of the Temperature Regimes in a Layered Bimetallic Plate under Short-Term Induction Heating

“…Such elements are affected by various physical factors, such as power, thermal, and electromagnetic ones, while technological functioning and operation. There are certain studies of the power and thermal factors that influence the temperature distribution in bimetallic plate elements [17][18][19][20][21]. In [17], the joining of layers of the Al-Cu bimetallic composite and the diffusion process on edge between the layers using hot rolling are analyzed.…”

Corrosion Behavior of AISI 316L Stainless Steel Used as Inner Lining of Bimetallic Pipe in a Seawater Environment

“…Bimetallic pipes, designed to improve anti-corrosion performance in oil and gas production pipelines, provide a wide range of application prospects due to their excellent mechanical properties and capacity to resist corrosion [ 1 , 2 , 3 ]. They are produced by the mechanical or metallurgical bonding of ordinary, usually carbon steel, pipes with an inner lining of corrosion-resistant alloy.…”
