Sorry I did mistake. Actually in clamp catalogue write it down 30 ksi and I wrote by mistake kpi .so this is stress unit, and just tell me please how can I calculate the clamp can bear 43000 N forces when pipe is going up. Already we did stress analysis and with this force we are not going to...

Dear friend Thank you for your answer .this pipe is going to input of a compressor .we don’t like flange of the compressor get over stress .yes you are right .we can change piping arrangement to limit or reduce force, but it is not time to do this change for us . Would you please tell me...
