RE: Hydro Test Pressure

thanks again everett. here's what we're using and results is quite good. for lineal scratches - depth not to exceed serration and projected lenght not to exceed 33%. pitting is limted to max of 2.4 dia. no arcs or weld spatter permitted. only 2 anomalies max between two adjacent bolt. saves time in refacing. our damage anomalies spec of course contained a lot more dtail which i can not share in this forum (copmpany policy).

Opps, Ralph I fogot to answer your other question about flange facing imperfections. There isnt a good guide for this other than B16.5 table 3. This list the permissible imperfections in the flange face finish for new flanges, but would be applicable for in-service flanges also. Its varies per NPS flange size. Everett
