Hi Punit,Please look at this generic oil and gas standard, page 109-115(both for cold and induction bends). The other good document to follow is ASME B-16.49, standards for induction bends. The presentation of Barry Crouch gives a good snapshot of the process and effects of different variables. The soak temperature for duplex and CRA clad pipes could be close, between 1050-1100 Deg C based on piping wall thickness.Prior to performing production, "Qualification Bends" are must to standardize bending parameters, and check the various required mechanical properties of the bends. Norsok document (M-630) provides many of such details.Thanks.Pradip Goswami, P.Eng,IWEWelding & Metallurgical SpecialistOntario, Canada
