PROTECTED PIPELINES
East - West Pipeline Runs From East To West Across
Country To Transport Oil And Gas From East Part (A) To West Part (B) In Order To
Supply Energy For The Many Industrial Projects and The Pipeline From North Part
(C) To The South Part (D) Of The Country.
CATHODIC PROTECTION
Cathodic Protection (CP) system protects metal
pipelines against corrosion.
Impressed CP system relies that Transformer
Rectifiers (TR) are supplying consistent
DC current to underground anode
beds. Too low TR current leads to corrosion but too high current can lead to disbonding of the pipe coating and hydrogen embrittlement.
CP MONITORING SYSTEM
AutoLog Cathodic Protection (CP) monitoring
system monitors CP Transformer Rectifier’s impressed current, voltage and optionally pipe-to-soil potential measurements.
CP COMMUNICATION
Cathodic Protection (CP) system sends measurement data wirelessly to nearest base station.
AutoLog
Cathodic Protection system can send measurement data using the following
networks:
• Conventional
Radio Network
• TETRA Network
• GSM Network
• RS-485 Network
• TCP/IP Network
Base stations are connected together to form one
huge communication network which covers the whole East West- and South to North
pipeline areas.
CP SCADA SYSTEM
From SCADA application users can see rectifier locations on map, alarms from abnormal situations and all measurements in trend lines. Measurements and alarms are stored in SCADA server's SQL database.
