"AT EI 199 A ATMOSPHERIC BOLT ON CLAMP INSTALLED IN OCTOBER 2003 HAS DEVELOPED A LEAK AT THE SEAM EDGE OF THE CLAMP. THE CLAMP IS INSTALLED ON AN 8"" DEAD LEG SECTION OF PIPE. TO ISOLATE THE CLAMPED SECTION OF PIPE THE ENTIRE 737 20"" PIPELINE WILL HAVE TO BE ISOLATED AND BLOWDOWN. A REPAIR PROCEDURE WAS DEVELOPED.
