GERALD, To be more specific would it be safe to assume that because i am knowledgeable in MIL-STD-1689,248,2035, 8000,and 7000 brazing that i should be able to adapt to ASME,etc. documents used in the commercial world? I dealt briefly with API 1104 PIPE LINES and ASME documents during CWI training and passing the 3 tests. Since you have worked with both you would know more about the comparison of the 2;NAVY STDS. vs commercial stds. DON KUMPUNEN SUP SHIP PASCAGOULA
