Out of my comfort zone here ...
We have to engineer an offshore platform wellbay to accommodate around 1000 barG through to production and test manifolds. The production manifold will need to be approximately 500mm OD and around 100mm thickness. Around 10 branches of about 300mm OD and 70mm thickness will enter the manifold at around 1500mm spacing.The proposed material is super duplex stainless.
That's the easy bit. My question is ... how might we manufacture the manifold and branches ?
Hot isostatic pressing looks attractive because we could tailor the design to accommodate required pressure reinforcment, but ... it possible to use HIP with super duplex ?
If HIP is possible, are there significant welding problems with joining super duplex at this sort of thickness ?
Comments appreciated !
