Pipeline Components Underground Pipeline system Pipeline External Coating: 3 layer PE (Polyethylene) Coating Cathodic Protection System Communication System: Dedicated Microwaves, OFC, GPRS and GSM System SCADA: Monitoring & Controlling from NGMC and RGMCs Sectionalizing Valve (SV) Stations Intermediate Pigging Station Terminals- RT/ DT

Compressor Station Components Gas Turbine Compressors Gas Turbine Generators/Gas Engine Generators Instrument Air Compressors Emergency Diesel Engine Generators Gas Conditioning Unit Gas Metering System Control Room Fire water System

COMPRESSOR STATIONS & NATIONAL GAS MANGEMENT CENTER More than 150 Control Rooms NGMC & RGMCs Compressor & LPG Pumping Stations Fire Control Rooms Terminal & Maintenance Base Control Rooms NGMC: Real time data of Pipeline Parameters, Supply and Delivery Conditions at Sources and Major Customer terminals through SCADA. Monitoring of pipeline hydraulics on round the clock basis. Nodal centre for crisis management of GAIL installations

GAIL’S PIPELINE ATTRIBUTES Approx. 740 nos. of Pipeline Sections Pipelines ranging from 4 IN to 48 IN Dia 99% of Pipelines are of Carbon Steel Steel Grades API 5L X GR B to X80 Design Code of NG Pipelines: ASME B31.8, T4S, OISD-226 & LPG Pipeline: B31.4, T4S, OISD 214 Dia: IN % of Total Length

PIPELINE PIGGABILITY Most of the Pipelines are Piggable ~ 89% (By Length) Most of the LMC’s connectivity is smaller in length

OPERATING PRESSURE OF PIPELINES W.R.T. SMYS 47 % of pipelines (By number)  operate below 50 % of SMYS Operating Pressure as % SMYS

EXTERNAL COATING SYSTEM More than 95% of Pipelines are having 3-layer Polyethylene coating Some older Pipelines (most taken over from ONGC) are having Coal tar Coating Close to 500 Kms of such Ageing Pipelines are under various stages of replacement

Cathodic Protection System 100% Pipelines covered by CP Most of the Pipelines are having Impressed Current cathodic protection (ICCP)

Sources & Consumers NG Sources: LPG Sources: Total NG sources : 70 Suppliers : ONGC, PLL, RGTIL, RGPPL, OIL, CAIRN , FOCUS ENERGY, HLPL, HOEC LPG Sources: Total Sources : 6 Suppliers: IOCL, HPCL, RIL, CAVERN, EIPL NG Consumers: > 500 nos. from Power, Fertilizer and other industries like CGD networks across the country

Sector wise Supply * Others include Steel, Refineries, Sponge Iron, Petrochemicals, GAIL Internal consumption etc.

Journey Ahead GAIL is spearheading development of Natural Gas infrastructure in the country: Very important for economic progress and addressing environmental concerns Extending the pipelines to the regions of the country not connected so far Jagdishpur-Haldia-Bokaro-Dhamra Pipeline (JHBDPL) with CGD Networks along 7 nos. of cities Barauni-Guwahati Kochi-Koottanad-Bengaluru-Mangalore Pipeline (KKBMPL)-Ph-2 GAIL pipeline operations focussed on adoption of new technologies in Pipeline Integrity Management and Efficiency.
