The Corrosion Control Department Comprises of 35 Executives and 179 Subordinates working in four Transmission Sections and Thirteen Distribution Regions.
Corrosion Control Department is proactive in protecting the underground company Transmission and Distribution pipeline network, from attack of corrosion and rust by applying Cathodic Protection technique through 1530 CP Stations covering MS Distribution Network of 67404 Kms and Transmission Network of 7656.26 Kms. CP System is monitored through 32987 Test points on pipeline network. The CP data collected from field is compiled in data base cell at Corrosion Control Centre.
The department has been established to perform following core activities.
1- Design and Construction
2-Monitoring and Maintenance
1- Underground Gas Leak Detection
We are also contributing in UFG Reduction Plan by conducting Underground Gas Leak Detection surveys through Laser Base Detectors and has successfully scanned 87,215 KMs (90% of Total Gas Network) of Distribution gas network by detecting 285024 leaks from which 204169 have been rectified.
2- Coat & Wrap Section (Transmission)
Coat & Wrap activities for recoating on Transmission line have also been handed over to Corrosion Control Department and we have recoated 24.1 Miles of Transmission line during last year.
3- Coat & Wrap Section (Distribution)
We have been assigned a new job of recoating of Distribution Network. The proposed tender document of which has been approved to carry out the job in fiscal year 2014-15.
1- Remote Monitoring of CP System
We are remotely monitoring 28 Nos. of our CP Stations on transmission network by employing SCADA based Remote Monitoring Units. Moreover 08 Nos. GSM based Remote Units along with data logging accessories are being installed as a pilot project in Islamabad-D.
2- Alternate Source of Energy for Un-Interrupted CP System
Providing un-interrupted cathodic protection to our networks is our high priority objective. In pursuance to this objective we have employed alternate energy sources i.e. Thermoelectric Generator (TEG), Solar Panel System, Battery Backup System etc.
3- Pipeline Integrity Management
In order to ensure the integrity of our high pressure Transmission networks a Pipeline Integrity Management Plan had been chalked out in line with ASME B31.8S.
