## Business segments

Tenaris reports one major business segment, Tubes, which is also its sole reportable operating segment. Tubes produces and sells steel tubular products and related services, principally for oil and gas applications, including OCTG for drilling and line pipe for transportation and processing, as well as mechanical and structural tubes for industrial uses. In 2025, Tubes generated net sales of $11.400 billion, approximately 95.2% of total segment-table net sales of $11.981 billion. [28](https://app.finbar.com/go?id=P147834626)[29](https://app.finbar.com/go?id=P147834629)[30](https://app.finbar.com/go?id=T16927228)

“Other” is an aggregation of activities not required to be reported separately, rather than a second reportable segment. It includes oilfield and hydraulic-fracturing services, sucker rods, coiled tubing, tubes for plumbing and construction, and excess energy and raw materials. Other generated $581 million in 2025 net sales, approximately 4.8% of the segment-table total.

## Company history

Tenaris’s industrial roots lie in the Techint Group, founded by Agostino Rocca in 1945. Its pipe-making history took shape with the opening of Siderca’s seamless-pipe mill in Campana, Argentina, in 1954, and the start of Tamsa’s seamless-pipe operations in Mexico that same year. [32](https://www.techintgroup.com/en/about-us) [33](https://www.tenaris.com/en/news/2024/70-years-of-industrial-excellence-in-argentina) In 1993, Siderca and Tamsa formed an alliance; Dalmine joined in 1996, creating the foundation for a broader international business. [34](https://www.tenaris.com/umbraco/surface/downloads/pdf?url=%2Fmedia%2F1gdpwrng%2Ftenaris-institutional-presentation-2021.pdf)

The Tenaris brand was introduced in 2001, and in 2002 the predecessor businesses were combined through an exchange offer. Tenaris began trading on the New York and Mexican stock exchanges in December 2002, followed by the Italian Stock Exchange the next day. [34](https://www.tenaris.com/umbraco/surface/downloads/pdf?url=%2Fmedia%2F1gdpwrng%2Ftenaris-institutional-presentation-2021.pdf) [35](https://app.finbar.com/go?id=P147842352) The company expanded its product capabilities with the launch of Dopeless® technology in 2004 and broadened its North American presence through acquisitions including Maverick Tube in 2006 and Hydril in 2007. [36](https://www.tenaris.com/en/news/2024/20-years-of-dopeless-technology) [37](https://ir.tenaris.com/static-files/5607c1f3-ffe2-4c12-b838-dce7127c3d42) [38](https://www.tenaris.com/en/about-us/)

Later milestones included the 2020 acquisition of IPSCO Tubulars and the 2023 expansion into pipe coating through acquisitions from Mattr and isOplus.
