Pipelines provided a very convenient mode of transport to connect oil and natural gas fields, refineries and to the markets.
In the past, these were used to transport water to cities and industries.
Now solids can also be transported through a pipeline when converted into slurry.
The initial cost of laying pipeline is high but subsequent running cost is minimum.
It can be laid through difficult terrain as well as under water.
It ensures steady supply of goods and reduces the transshipment losses and delays.
