This paper briefly describes induction bending and highlights some of the challenges associated with this technique in the production of tight bends in thick-walled pipe. The authors then go on to describe how data obtained from production runs and specifically commissioned trial bends were used to examine the factors believed to influence the ...

An Investigation on Microstructural Evolution of X70 Steel Pipe During Hot Induction Bending
Volume 1: Pipeline and Facilities Integrity, 2018It is generally accepted that hot induction bending (HIB) results in a decrease in strength and an increase in fracture toughness in bend area, heat affected zone (HAZ) and weld metal (WM). As the result, Post bend heat treatment (PBHT) is not considered to be a requirement and could be waived for saving money and time.

Modelling and Predicting the Deformed Geometry of Thick-Walled Pipes Subjected to Induction Bending
Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2010Induction bending offers a rapid, cost-effective method of producing complex convoluted pipework. The resultant bends, however, typically show unwanted geometric deformations which include wall thinning at the extrados, wall thickening at the intrados, awkward transitions on going from tangent to bend, and wrinkling at the intrados surface.

Study on the Heating Process and Properties of X80 Induction Heated Bending Pipe
Volume 6: Materials and Fabrication, Parts A and B, 2009Induction heated bending pipe is an important connecting piece widely used in natural gas pipeline. As the persistent development of natural gas pipeline project, the X80 induction heated bending pipe needed to be developed and studied. The local induction quenching process and the wholly induction quenching process were adopted to develop the Φ1219mm ...

In this study, the deformability of induction bends made out of high-grade line pipe is analytically discussed. In order to clarify the significant parameters for the deformability, 30 cases of finite element analyses simulating the deformation behavior subjected to internal pressure and bending moment were carried out.

Hot induction bending is a process applied to tubes produced for the oil and gas industry, where bending temperatures above Ac3 can be reached. The base metal is submitted to two thermal cycles, one during welding, generating the heat affected zone (HAZ), and another during bending when this HAZ is reheated. Also, after the bending process is completed,

The heat treatment during manufacturing process of induction bend pipe had been simulated. The evolutions of ferrite, M/A island and substructure after tempering at 500~700 °C were characterized by means of optical microscopy, positron annihilation technique, SEM, TEM, XRD and EBSD.
