Well , actually I changed the temperature to 315 but the same applies. For the maximum sustained stress it should be 11 percent of the allowable on the branch run of the tee at node 30, for my case it is 59.2% at node 30.
Besides, it said for me code stress failed for the expansion stress ( normally beceause of the high temperature 315 celcius) .

Furthermore, I think the high value of stress for my case is mainly due to the 2 inch by-pass, as in the tees we have 2 inch * 8 inch.

Concerning the job task, you will find attached the job changed, as well as the seminar job desciprtion.

Please check with me , maybe there is an error in the seminair job tasks.

Looking forward to our reply
