Oil & Gas Industry-- Pipeline Pressure Monitoring

✅Transmitters Used:

• Differential Pressure (DP) Transmitters – Measure pressure drop between two points.
• Multivariable Transmitters – Simultaneously measure pressure, temperature, and flow.

✅ Configuration:

• Installation Type: Flange-mounted or threaded connection on pipelines.
• Material: 316L Stainless Steel or Inconel for corrosion resistance in saline offshore environments.
• Seals: Remote diaphragm seals with capillary tubing for high-temperature or hazardous locations.

✅ Communication Protocols:

• HART Protocol: Provides 4-20mA analog signals with digital diagnostics.
• Modbus RTU/TCP: Ideal for long-distance data transmission to SCADA systems.
• WirelessHART: Used for remote monitoring of offshore platforms and hard-to-access locations.

✅ Failure Modes & Mitigation:

• Blockage in Impulse Lines: Regular blowdown and maintenance of impulse lines to prevent clogging.
• Seal Fluid Loss: Use of double-diaphragm seals with regular calibration checks.
• Overpressure Damage: Surge protection installed to prevent transmitter damage during pressure spikes.

✅ Results:

• 30% improvement in pipeline safety.
• Early leak detection reduced environmental risks by 25%.
