Selectron and installation of CRA clad flowines in the madden deep unit

摘要

Tis paper describes the selection and installation of Corrosion Resistant Alloy (CRA) clad flowlinges and solid Alloy 625 piping wellhead tie-in for hook-up of wells in the Madden Deep Unit of Wyoming. The highly corrosive nature of the gas, coupled with the anticipated production of elemental sulfure and the close proximity to populated areas, dictated the use of these specialty materials. The special fabrication and installation requirements for CRA clad flowlines, including some of the difficulties, are presented.
