Advantages and Disadvantages of Pipelines in India!

Pipelines are most convenient, efficient and economical mode of transporting liquids like petroleum, petroleum products, natural gas, water, milk, etc. Even solids can also be transported through pipelines after converting them into slurry.

Transportation by pipelines is a new development in India. Pipelines have relieved the increasing pressure on the existing surface transport system (railways and roadways).
