Problem:
Emergency relief vent
Glass Lined Pipe
Runaway reaction.

Synopsis.

Glass lined reactor has glass lined pipework to the Condenser and then onto the Bursting disk.
After Bursting disk, pipework changes to SS and runs to relief tank.
Runaway reaction in reactor causes pressure to rise, causing burst disk rupture at 2barg
Pressure continues to rise until 40 secs later it peeks at 8barg.
There are 2 bends before the BD and 4 bends after


Problems

I have two main problems,

1.Relief forces.
I have two relief force scenarios here, i intend to do:
a) one run with the 2bar dynamic forces acting on the first elbow before the BD and on each elbow after the BD
b) The pressure rise to 8barg after the Disk has gone is over 40sec and can be ignored


2.Glass lined Pipe.

The vendor has provided nozzle charts and has asked that the pipe flange forces do not exceed same. Pipe Stresses are to be kept below b31.3 Alllowables to avoid yielding.

I have had no account of pipe deformation allowables from the vendor and can only think that
either to some extent, the glass is ductile, or that the vendor is mistaken?

To analise the forces i have placed a cnode at each flange, i have also split each spool into two to asses midspan forces and moments.

So, Am i going in the right direction????
