Industrial LPG Pipeline

India’s first company to own and operate pipelines for LPG Transmission

GAIL is the first company in India to own and operate pipelines for LPG transmission. It has 2040 km LPG pipeline network 1,427 km of which connects the western and northern parts of India and 610 km of networks is in the southern part of the country connecting Eastern Coast. GAIL has dedicated LPG pipelines from GPU, Gandhar (1 Km length) and GPU Vijaipur to OMC Bottling plants (2 Km length). The LPG transmission system has a capacity to transport 4.58 MMTPA of LPG.

GAIL is augmenting Jamnagar-Loni Pipeline capacity from 3.25 MMTPA to 6.5 MMTPA. GAIL is also executing Uran-Usar Propane pipeline and Vijaipur-Pata C2/C3 pipeline.

GAIL LPG Characteristics

  • Processed from Natural Gas
  • Has a high vapour pressure vis-a-vis Refinery LPG
  • Vaporises at atmospheric temperature and pressure
  • Clean fuel with almost 'NIL' unsaturated compounds
  • Has a higher calorific value than Refinery's LPG and hence gives more value for money
  • Its homogeneous composition results in more efficient combustion
  • The air fuel ratio need not be changed with every batch
  • No Impurities like sulphur, carbon dioxide, traces of oxides of nitrogen. Hence having least corrosion compounds
  • Has 'NIL' moisture content
