Indian Pipe Stocks Ride America’s AI Infrastructure Buildout
Artificial-intelligence data centres need a lot of electricity and cooling.
In the United States, some data-centre developers are pairing their facilities with gas-fired power plants.
Those plants need pipes to carry natural gas.
Data centres also need special pipes to move cooling fluids and steam.
Welspun Corp makes large pipes and has many orders connected to the US energy market.
DEE Development Engineers makes specialised pipes used in cooling systems and power equipment.
Both companies reported strong financial results and have sizeable order books.
However, their share prices have already risen sharply, so the article says investors should study the valuations and seek advice rather than treat the information as a recommendation.
Welspun Corp and DEE Development Engineers are benefiting from rising demand for gas and cooling infrastructure linked to data centres.
Welspun holds an estimated 33%-35% of the US large-diameter line pipe market, with US capacity booked through FY28.
Welspun’s global order book stood at ₹42,100 crore as of 20 August 2026, including a ₹17,200 crore US plant order.
DEE Development Engineers’ Thailand plant is fully booked for three years supplying specialised piping for heat-recovery systems.
The companies’ shares rose 200% and 179%, respectively, in 2026, leaving both trading above historical median valuations.
