1.3.2 Pipe cleaning maintenance
WARNING
BURST HAZARD
Before pipeline cleaning and maintenance ("pigging operations"), remove straightening
vanes or flow conditioners.
Failure to comply may cause excessive pressure in the meter system, resulting in death,
serious injury or equipment damage.

bidirectional flow
Straightening vanes or flow profilers must be removed during pipeline cleaning
maintenance operations (“pigging operation”). If the meter run is pigged with a flow
conditioner in line, pressure may build up and cause the pipes and flanges to burst and
severely injure personnel. The excessive pressure may damage the meter or the
transducer ports may collect debris which may impede data acquisition and flow
measurement.
1.3.3
Visual inspection
