July 31 (Reuters) - Enbridge ( ENB ) beat estimates for

second-quarter adjusted profit on Friday, helped by higher

volumes of liquids transported on its Mainline system.

Pipeline operators such as Enbridge ( ENB ) are benefiting from

increasing demand for natural gas, utility infrastructure and

power supply for data centers, enabling the company to generate

steady growth even amid geopolitical tensions and commodity

price volatility.

Its Mainline system, which moves nearly half of the crude in

the United States, saw second-quarter adjusted core profit rise

to C$1.57 billion ($1.12 billion) from C$1.5 billion a year ago.

The pipeline system is the largest in North America and

transports light and heavy crude oil, natural gas liquids and

refined products from Edmonton, Alberta, to various markets in

Canada and the U.S. Midwest.

The company reported adjusted profit of 63 Canadian cents

per share for the quarter ended June 30, beating analysts'

average expectation of 59 Canadian cents, according to data

compiled by LSEG.
