hi everyone,

I understand double rail kamprofile gaskets are usually a good alternative to get you out of a hole if RTJ groove is deformed. The conversion process involves machining the flat edges either side of the groove to achieve the typical surface roughness.

My question is:
How would you adopt the double rail kamprofile into the PCC-1 appendix O (joint approach method) - i.e, do you combine the two areas of the landing portion of the double rail?
Further to that, any guidance/experience on how to set up moment arms for HG, HT and HD in WRC538 calculations?

My concern is adopting the low bolt stress values typically assigned for RTJs to the double rail kamprofile wouldnot be enough to seat the double rail gasket.

Thanks in advance.
