Hydro testing OTSG (ASME Sec 1) Original plan was to use two separate hydro test packages for testing the completed boiler assembly. One for the boiler proper (@ 16950 Kpa = 1.5 MAWP) & another test for the Boiler Feed Water (BEP) (@ 22050 Kpa = 1.5 Design Pressure). These units are Forced Flow Steam Generators. As-per ASME Sec 1 (Paragraph PG-99.3) states A completed forced-flow steam generator with no fixed steam and waterline, having pressure parts designed for different pressure levels along the path of water-steam flow, shall be subjected to a hydrostatic pressure test by the above procedure (PG-99.1 and PG-99.2). Is there any code case or additional information out there to support one hydro test.
