HVJ an abbreviation for Hazira-Vijaipur-Jagdishpur (also known as HBJ where B stands for Bijeypur, another name of Vijaipur) is India's first cross state gas pipeline.
The project was started in 1984 after the incorporation of GAIL (India) Limited to supply gas to the fertilizer plants located in the state of Uttar Pradesh.
Later on the system was expanded with additional branches to supply gas for industrial and domestic use in the states of Rajasthan, Haryana and NCT, which increased the total grid length to 3,474 km.

The HVJ pipeline system consists of receiving and dispatch terminals for the supply of metered gas, compressor stations for boosting the pressure of gas, the SCADA system to provide central monitoring and control and a dedicated GAILTEL communications system to provide reliable voice and data communication.
