The total order value stands at around Rs 753 crore and the total length of pipe to be supplied is an estimated 735 km, the company said in a statement.
The company will supply line pipe and three-layer polyethylene coating for GAIL's Kochi-Koottanad-Bangalore- Mangalore Gas Pipeline (KKBMPL) project.
"The recent orders we have secured from GAIL have special significance for PSL as a company, since they stand as a testament to our capability as a key enabler of India's gas pipeline and infrastructure projects," PSL managing director Ashok Punj said.
The annual pipe manufacturing capacity of the company stands at 1,775,000 MT per year.
