Flange alignment procedure
WebMar 17, 2024 · Relaxation passes and start-up re-torquing procedures are used in specifications to help prevent leakage and increase sealing performance in ANSI pipe flanges, heat exchangers, and other pressure boundary joints. Relaxation Pass: This is a circular torque pattern on a bolted flange joint assembly at the same torque value as the … Webin the alignment of the joint, one side of the joint should be left unwelded or “loose” prior to fit up of the joint. This will allow the flange to be fitted in place and checked for gross alignment before being welded to the pipe joint so that bolt hole alignment, and correct distance between the flanges can be verified.
