Thanks doct9960, it worked increasing boot thk. As it is an existing vessel, can't increase vessel thk (1.328"), of course new boot thk is very thick now= 1.6875"
Thanks,
Do you mean repad? I have added a repad already and it passes for internal pressure, the problem is about bending moment cause of big boot diameter. Although I increase repad, it doesn't help
hi
I have a 9' ID vessel with a 4.5' ID drop leg (boot), but it's failing cause of bending moment due to large diameter, acc. to App. 1-7(b).
Is there any way to solve this problem without boot diameter changing?
Hi
I have to add some new nozzles to an existing vessel built in 1950 using BSS 14 for shell & heads. In order to calculate nozzles, I need to know material properties but I haven't be able to get it. I guess this material was already withdrawn. Does anybody know about BSS 14?
Thanks
