Collaborative Continuum: Tenova & Tenaris's Trusted & Time-Tested Technology Partnership The contract awarded by Tenaris to Tenova for the Electric Arc Furnace revamp at the Koppel, Pennsylvania steel mill, announced on 29 June 2026 from Castellanza, Italy, represents the latest chapter in a long-standing collaboration between two of the global steel tube industry's most technically distinguished organisations, a relationship built on successive successful project deliveries & a shared commitment to advancing the operational performance of steelmaking facilities. Tenova, a leading developer & provider of sustainable solutions for the green transition of the metals industry, operates through its US subsidiary Tenova Inc. for North American projects, ensuring that engineering, manufacturing, & project management activities are executed entirely within the United States, a feature that Francesco Memoli, Chief Executive Officer of Tenova Inc., explicitly highlighted as a strategic advantage for the Koppel project. Tenaris, the global leader in the manufacture & supply of seamless steel pipes for the energy industry, acquired the Koppel steel shop & the adjacent Ambridge seamless pipe manufacturing facility in Pennsylvania in 2020, & has since invested more than $150 million in the two sites, building a vertically integrated production system that converts recycled scrap steel into finished seamless oil country tubular goods for the United States energy sector. The Koppel facility occupies a foundational position in this integrated production chain: steel billets are produced in the electric arc furnace at Koppel, shipped to Ambridge for rolling into seamless pipes according to customer specifications, returned to Koppel for heat treatment through quenching & tempering followed by finishing & non-destructive testing, & then sent to the Brookfield, Ohio facility for threading & final inspection before shipment to oil & gas customers across the United States. Francesco Memoli, Chief Executive Officer of Tenova Inc., stated: "We are proud to continue our collaboration with Tenaris & to contribute to the modernization of the Koppel facility. Projects like this reflect our shared commitment to innovation & to supporting the long-term competitiveness of steel production. Executing the project entirely in the United States, from engineering to manufacturing, will also ensure close coordination with the customer & efficient project delivery." This commitment to domestic execution is not merely logistically convenient but reflects a deliberate alignment the broader policy environment favouring domestic manufacturing & supply chain resilience in the United States .

Pennsylvania's Prolific & Progressive $90 Million Modernisation Mandate The Electric Arc Furnace revamp contracted to Tenova forms a key component of a comprehensive $90 million investment programme that Tenaris announced on 23 June 2026 for its Pennsylvania operations, a programme that spans both the Koppel steel shop & the Ambridge seamless pipe manufacturing facility & represents one of the most significant single-announcement investment commitments in the Pennsylvania steel industry in recent years. The $90 million programme complements an additional $150 million already invested by Tenaris since acquiring the Koppel & Ambridge locations in 2020, bringing the company's total capital commitment to the two Pennsylvania facilities to more than $240 million over six years, a figure that underscores the depth & durability of Tenaris's commitment to domestic United States manufacturing. The investment programme is designed to introduce automation & equipment upgrades aimed at improving productivity & reliability in both production processes, as well as increasing safety for employees on the shop floor, a three-part objective that reflects the integrated nature of operational excellence in modern steelmaking, where productivity, reliability, & safety are mutually reinforcing rather than competing priorities. Beyond the Electric Arc Furnace revamp, the $90 million programme includes upgrades to higher capacity ladles at the Koppel steel shop, allowing for increased production capacity & enhanced safety, the addition of a steel bar yard at the Koppel facility paired a new bar cutting area in Ambridge to streamline activities between the two locations & reduce logistical risks, & an upgrade to the shredder at the scrap processing centre adjacent to the steel shop, following Tenaris's acquisition of Steel Recycling Services, which had previously acquired the scrap processing assets from SA Recycling. Guillermo Moreno, Tenaris US President, stated: "This improvement plan is another important step to bring our long-term vision for our Ambridge & Koppel facilities to fruition. We are proud to supply US oil & gas customers products made here in Pennsylvania & around the country. As demand for American energy grows, we will continue to prioritize investments that maintain our standing as a reliable partner for US operators." Work on the new upgrades is expected to begin in the coming months, the majority of projects extending into the second half of 2027 .

Furnace Fundamentals: the Electric Arc Furnace's Essential & Enabling Role in Koppel's Production Chain The Electric Arc Furnace at the Koppel steel shop is the foundational production unit of Tenaris's entire Pennsylvania manufacturing system, converting recycled scrap steel into the high-quality steel billets that feed the seamless pipe rolling operations at Ambridge, making its operational performance a direct determinant of the quality, consistency, & cost-competitiveness of the finished seamless pipes that Tenaris supplies to United States oil & gas customers. Electric Arc Furnace steelmaking uses high-voltage electrical arcs to melt scrap steel charges, generating temperatures exceeding 1,600 degrees Celsius that reduce the solid scrap to liquid steel, which is then refined in the ladle metallurgy station before being continuously cast into the billets that serve as the raw material for seamless pipe rolling. The quality of the billets produced by the Koppel Electric Arc Furnace directly determines the metallurgical properties of the finished seamless pipes, including their tensile strength, toughness, corrosion resistance, & dimensional consistency, all of which are critical performance parameters for oil country tubular goods used in demanding downhole environments. The Koppel Electric Arc Furnace has been the subject of sustained investment by Tenaris since the 2020 acquisition, including an $85 million exhaust system upgrade completed in 2025 that enhanced the facility's environmental performance & operational sustainability, reducing particulate & gaseous emissions from the furnace operations. The revamp contracted to Tenova represents the next phase of this sustained investment programme, targeting the operational efficiency, equipment reliability, & process control dimensions of the furnace's performance rather than its environmental systems, which were addressed by the earlier exhaust system upgrade. The Tenova revamp will deliver advanced solutions aimed at improving operational efficiency & safeguarding critical equipment, a dual objective that reflects the two primary drivers of Electric Arc Furnace modernisation investment: reducing the cost per metric ton of steel produced & extending the operational life of capital-intensive furnace components .

Water's Watchful Wisdom: the Innovative Cooling Circuit Measurement System's Significance The most technically distinctive element of the Tenova revamp scope is the implementation of an advanced water flow measurement system for the furnace upper shell, an innovation that addresses one of the most critical operational & safety challenges in Electric Arc Furnace steelmaking: the monitoring & control of the water cooling circuits that protect the furnace's structural components from the extreme thermal loads generated during steelmaking operations. Electric Arc Furnace upper shells are water-cooled panels that form the upper portion of the furnace vessel, protecting the structural steel of the furnace body from the intense radiant heat & splashing molten steel generated during the melting process. These cooling panels circulate large volumes of pressurised cooling water through internal channels, & the integrity of this cooling system is a fundamental safety & operational requirement: insufficient cooling flow can lead to panel overheating, distortion, & ultimately catastrophic failure, while undetected cooling water leaks into the furnace can cause dangerous steam explosions when the water contacts the molten steel bath. Conventional water flow monitoring systems in Electric Arc Furnaces typically provide aggregate flow measurements for groups of cooling circuits rather than individual panel-level monitoring, limiting the ability of operators to detect localised flow restrictions or leaks before they develop into serious problems. The advanced water flow measurement system that Tenova will implement at Koppel provides highly accurate monitoring & control of individual cooling water circuits, giving operators real-time visibility into the thermal state of each cooling panel & enabling early detection of anomalies that could indicate developing problems. This granular monitoring capability contributes to greater operational stability & optimised process conditions, as operators can make informed decisions about furnace operation based on accurate real-time data rather than relying on aggregate measurements that may mask localised problems .

Safety's Supremacy: Protecting Personnel & Plant Through Proactive Process Monitoring The emphasis on employee safety that runs through both Tenaris's $90 million investment programme & the specific technical features of the Tenova Electric Arc Furnace revamp reflects the steel industry's growing recognition that operational excellence & worker safety are inseparable dimensions of sustainable industrial performance, & that investment in safety-enhancing technology delivers both human & financial returns. Electric Arc Furnace steelmaking is an inherently hazardous process, involving extreme temperatures, high-voltage electrical systems, large volumes of molten metal, & the potential for sudden & violent process upsets including electrode breakages, furnace shell failures, & cooling water incidents. The advanced water flow measurement system that forms the centrepiece of the Tenova revamp directly addresses one of the most significant safety risks in Electric Arc Furnace operations: the undetected failure of cooling water circuits, which can lead to the rapid overheating & structural failure of furnace components, potentially causing injuries to personnel working in the vicinity of the furnace. By providing highly accurate, real-time monitoring of individual cooling circuits, the system enables operators to detect developing problems at an early stage, before they escalate into safety incidents, & to take corrective action while the furnace is still under controlled conditions. The broader $90 million investment programme's safety dimension includes the higher capacity ladles at Koppel, which reduce the risk of ladle handling incidents by providing greater structural margins & improved handling characteristics, & the new bar cutting area in Ambridge, which streamlines the billet transfer process between the two facilities & reduces the manual handling risks associated with the current logistics arrangements. Tenaris employs more than 3,600 people across its United States operations, & the company's investment in safety-enhancing technology at Koppel & Ambridge reflects a corporate culture that places employee wellbeing at the centre of its operational philosophy .

Domestic Dedication: American Engineering, Manufacturing & the Reshoring Renaissance The decision to execute the Tenova Electric Arc Furnace revamp entirely within the United States, from engineering design through equipment manufacturing to on-site commissioning, carries significance that extends beyond the operational convenience of proximity to the customer site, reflecting a broader strategic alignment the United States government's policy priority of rebuilding domestic industrial manufacturing capability & supply chain resilience. Francesco Memoli of Tenova Inc. explicitly highlighted the domestic execution model as a feature of the Koppel project, noting that executing the project entirely in the United States will ensure close coordination the customer & efficient project delivery, a statement that captures both the practical logistics advantage of domestic supply & the strategic value of maintaining engineering & manufacturing expertise within the United States industrial base. Tenova's ability to execute the full scope of the Koppel revamp domestically, encompassing engineering design, equipment fabrication, & commissioning services, reflects the company's investment in building a genuinely capable United States subsidiary rather than simply using Tenova Inc. as a sales & project management front for equipment manufactured in Italy or elsewhere. This domestic execution capability is increasingly valued by United States industrial customers who face supply chain risks from internationally sourced equipment, including longer lead times, logistics disruptions, & the challenges of coordinating complex technical projects across multiple time zones & regulatory environments. The Tenaris investment programme's broader domestic manufacturing dimension is reinforced by the company's vertically integrated production model in Pennsylvania & Ohio, which converts domestically sourced recycled scrap steel into finished seamless pipes for United States energy customers, creating a supply chain that is entirely domestic from raw material to finished product .

Tenaris's Tenacious Track Record: Pennsylvania's Prolific & Progressive Investment History The Tenova Electric Arc Furnace revamp must be understood in the context of Tenaris's sustained & accelerating investment programme at its Pennsylvania facilities since acquiring the Koppel & Ambridge sites in 2020, a programme that has progressively transformed both facilities from their acquisition condition into modern, competitive steelmaking & pipe manufacturing assets capable of serving the most demanding requirements of United States oil & gas customers. The $150 million invested in the Koppel & Ambridge facilities between 2020 & the announcement of the new $90 million programme in June 2026 encompasses a series of major capital projects, most significantly the $85 million exhaust system upgrade at the Koppel steel shop, completed in 2025, which dramatically improved the facility's environmental performance & operational sustainability by upgrading the systems that capture & treat the gaseous & particulate emissions generated by the Electric Arc Furnace. In January 2026, Tenaris reactivated the heat treatment & finishing lines at Koppel following a $2.1 million investment, hiring more than 80 employees to support the reactivation & restoring the full integrated production capability of the Pennsylvania system. The reactivation of the heat treatment & finishing lines, combined the ongoing investment in the steel shop & the new $90 million programme, signals Tenaris's confidence in the long-term demand outlook for domestically produced seamless oil country tubular goods in the United States energy sector, a market that is driven by the country's sustained oil & gas production growth & the growing preference of United States operators for domestically sourced tubular goods. Guillermo Moreno, Tenaris US President, stated that reopening the heat treatment & finishing lines in Koppel reinforces the strength of domestic production capabilities for customers across the United States, describing Koppel as a cornerstone of Tenaris's United States operations .

Operational Optimisation: Efficiency, Reliability & Competitiveness Post-Revamp Upon completion of the Tenova Electric Arc Furnace revamp, the upgraded furnace at Koppel is expected to deliver measurable improvements across the full spectrum of operational performance metrics that determine the competitiveness of Electric Arc Furnace steelmaking, from energy consumption & electrode costs through to heat time, yield, & product quality consistency. The advanced water flow measurement system will contribute to greater operational stability by enabling more precise management of the furnace's thermal balance, reducing the frequency & severity of process upsets caused by cooling system anomalies & allowing operators to maintain more consistent furnace conditions throughout each heat. More consistent furnace conditions translate directly into more consistent steel quality, reducing the variability in billet chemistry & cleanliness that can cause quality rejections at the seamless pipe rolling stage & ultimately affect the performance of the finished pipes in demanding downhole applications. The safeguarding of critical equipment through improved cooling circuit monitoring also reduces the frequency of unplanned maintenance shutdowns caused by cooling panel failures, improving the furnace's availability & reducing the maintenance costs associated with emergency repairs to heat-damaged components. Tenova's scope of engineering, equipment supply, & commissioning services ensures that the revamp is executed as an integrated project rather than a series of disconnected equipment upgrades, with the commissioning phase providing the critical bridge between equipment installation & full operational performance, validating that the advanced water flow measurement system & other revamp components are functioning as designed & that Tenaris's operating personnel are fully trained in their use. The combined effect of the Tenova revamp & the broader $90 million investment programme is expected to position the Koppel & Ambridge facilities as among the most modern & competitive seamless pipe manufacturing operations in the United States .
