Tenaris is a leading global manufacturer and supplier of steel pipe products and related services for the world’s energy industry and other industrial applications. The company operates an integrated network of steel pipe manufacturing, research, finishing and service facilities with operations in the Americas, Europe, the Middle East, Asia and Africa. Tenaris serves most of the world’s leading oil and gas companies while also supplying pipes and tubular components for non-energy applications and low-carbon energy solutions such as geothermal wells, hydrogen storage and transportation, and carbon capture and storage.

Tenaris generates revenue through the sale of seamless and welded steel pipes, premium connections, couplings, and tubular components, as well as through value-added services including pipe coating, heat treatment, threading, and supply chain integration. The company also offers technical and digital services such as Rig Direct®, which manages customer inventories and delivers pipes directly to rigs on a just-in-time basis. Revenue is derived from a global customer base spanning energy producers, industrial operators, and infrastructure developers requiring high-performance tubular solutions.

The company operates through the following segments:

• Seamless Steel Pipes: This segment focuses on the production of seamless steel pipes used in oil and gas drilling, production, and industrial applications. Tenaris manufactures seamless pipes through facilities in Argentina, Mexico, Italy, Romania, Canada, the United States, Indonesia, and China.
