Note: This root cause analysis (RCA) is from real-time scenarios that happened in industries during the tenure of two or three decades ago. These articles will help you to improve your troubleshooting skills and knowledge.

Damaged Magnetic Flow Meter Flow Tube

All pipeline re-liners declining to reline or repair the 1½” Magnetic flow meter head flow tube end lining threatened junking the entire high cost imported head.

Author Repair

The author repaired the flow tube thus:

  1. Let the re-winder re-wind as the burnt winding
  2. Dressed the damaged liner even
  3. Tight fitted a shop made filled PTFE sleeve to make up the last lining
  4. Tight fitted a shop made 50-mm long carbon filled PTFE bush covering the sleeve and overlapping the liner. Bush collar dia = flow tube metal collar dia
  5. Assembled the rewound windings over the flow tube; The head is ready for calibration
  6. The head calibrated as described in the next problem worked fine several years.
Damaged Magnetic Flow Meter Flow Tube

Recurrence Eliminated

Fortunately, the Magmeters were 1 size smaller than pipeline size for higher velocities through the meter to avoid liquid carried particles depositing.

Hence, they came mounted between flanged SS pipeline reducers. The author strictly instructed the crew to unbolt both ends reducers to pipes flanges.

This way magmeters suffered no end lining damages ever.

Benefits

Author Repair Benefits are:

  1. Enabled production reduction within 8-hours and met the committed orders
  2. Besides the financial gains, it  preserved image as a reliable phosphate fertilizer supplier
  3. Saved a head purchase costs
  4. Found a way to handle future such problems
