Calculation method

The followin three criteria are to !e use" to chec# the strenth of trunnion pipe supports$

1. The %ello metho" &%ello's Su!(ect 3)10* for local stress in"uce" in pipe walls an" com!ine" local stresses are compare" with

factore" &1.5 for +SS,S+SS or maximum 2 times for other* hot allowa!le stress of the parent pipe which shall not excee" the followin limits$

aximum Total llowa!le Stress / 30#si &207 pa* for CS , LTCS SS .

5#si &310a* for +SS,S+SS.

2. el" strenth &llowa!le Stress for 4last Case ta#en as 1.5 x S 431.3 6ot llowa!le Stress*.

3. 4en"in strenth of trunnion &llowa!le Stress for 4last Case ta#en as 1.5 x S 431.3 6ot llowa!le Stress*.

Assumptions

The followin con"itions , assumptions hae !een use" in the calculations$

1. aximum allowa!le "esin pressure at am!ient as per material class specification use" in calculation as conseratie approach.

2. 6ot allowa!le stress at "esin temperature.

The purpose of this calculation is to chec# the strenth of trunnion pipe supports with rear" to local stresses in the trunnionwel" the parent pipe an" the trunnion pipe.

The cells with !" te#t on the calc sheets are re$uired input. These can be entered manually or the e#isting%&''()*% functions can be used providing the reference data is verified. +ells with black te#t are calculatedvalues and should not be modified

The main calc sheets uses data pulled from the following sheets that is specific to pro,ect piping specifications.These sheets should be modified for a specific pro,ect or deleted and then the data on the main calc sheets enteredmanually.
