Pipe Saddle for high temp application
Pipe Saddle for high temp application
(OP)
We are involved in designing a high temperature (500ºC) steam piping inside a power station. The pipe material selected is ASTM A335 P91 and the slippers (shoes/ saddles) of A387 Gr22.
Can somebody, having experience of designing piping for such temperature application recommend the correct/ proven type of slipper design?
Would it be ok to use standard welded design of slippers with the pipe? The concern is the differential thermal expansions between pipe and slipper - is a notch between either ends of the welded slipper design helpful?)
cheers,

You should get a copy of Pipe Fabrication Institute (PFI) Bulletin ES-26. PFI ES-26 is referenced by ASME B31.1. This document addresses the manner and details of welding the support appurtenance to the pipe wall.
