Hi,
I'm dealing a lot with FRP piping with application up to 20 bar, mainly for offshore services.
I'm trying to work out the required torque for the FRP flange, any idea what's the best reference to use?
I have look thru ASME VIII and it doesn't seem to address the torque calculation for flat face flanges. Also, I believe there is a need to consider the limitation of the FRP material during torque.
AFAIK, ASME RTP-1, NM-12 does contain some calculation in determining the torque value while considering the limitations of the FRP material. However, RTP-1 is meant for very low pressure, and I'm not sure how well it will work for pressure up to 20bar.
Appreciate some advice here.
Thanks!
