If you go through piping design books you will find that trunnion on elbow
reduces the flexiblity of trunnion & also it modifies the value of sif &
flexibility factor . piping design book (M W kellogg) chapter 4 -local
components expilicitly derives relation for the same, thats why most of
design companies dont prefer trunnion on elbows & use of pads for trunnion
on elbow is highly discarded as all these reduce flexibility of trunnion ,
which may be of concern in rigid layouts
hope this answers your query.
