No problem. Are you talking about clamps like the Grayloc or Tri-Clover variety?

I think the easy for doing this is to show that your clamp meets the code rules for a pressure which produces a unit axial load equal to the (calculated axial pressure stress + the calculated bending stress)/pipe wall thickness. This is fairly conservative, but it'll meet the U-2(g) requirements without a lot a extra work.
