Hello

Untied universal expansion joint is used on 10"pipe of 6 bar pr(g) connected to turbine exhaust nozzle and an anchor is placed at the bellow outlet(regular practise to provide incase of untied expansion joints). My requirement is to find forces and moments on turbine exhaust nozzle. By feeding effective id value in expansion joint because of huge thrust force , forces in tonnes axially transfered to the turbine exhaust nozzle.

My opinion is not to input this effective id value (meaning "0mm" effective bellow id), when we calulate "Turbine NOZZLE forces and moments".

this effective id can be fed to find the VESSEL forces. ie forces and moments generated can be given to the supplier to take care on the turbine and its foundation anchor bolts.

Your opinion on the subject matter please!!!!!!!!!!
