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.
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.
The author repaired the flow tube thus:
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.
