(Ask) Stress Analysis for Ammonia Shift Converter

[h9.hanin]

Dear Forum,

I have a little problem concerning the calculation of the stress analysis for the design of piping systems around the nozzle Shift Converter for Ammonia Plant.

Working temperature in the pipe is 200 Degrees Celsius.
Modeling of stress analysis is to consider Shift Converter as a rigid zero weight.
Well, because the elevation of the pipe nozzle is high enough, then the pipe system after nozzle experiencing hanging at each pipe support.

Is there any idea how to solve this problem?
Or what type of support that can be used to handle this problem?
Or whether there should be special treatment, for example by adding support expansion joint or spring?

Thank you very much for your response

Dear friend,
you need to give support from vessel , normally(first support after the nozzle) dummy support resting on the the bracket of vessel,(it must be conveyed to equipment manfacturee before fabrication) last vertical support may have the spring support to take care the differential expansion of vessel and pipe. this is just a guideline. some time we use spring first support. you need to see the verticlal length & expansion. other support will be all around guide.
