13. 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

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

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

16. 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

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

18. 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

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

20. 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.
