Tenaris SA
One of the world's largest makers of steel pipes for the energy industry, Tenaris supplies the seamless tubes used to drill and produce oil and gas, along with related services. The brand was born in 2001 when the Techint group folded older pipe makers—Italy's Dalmine, Argentina's Siderca, and Mexico's Tamsa—under a single global name. Its moniker is a made-up word evoking the Latin tenere ("to hold"), chosen to suggest steadiness and global reach.
