What Corinth Pipeworks does

Corinth Pipeworks (Σωληνουργεία Κορίνθου Α.Ε.) is a Greek steel pipe manufacturer operating as the steel pipe segment of Cenergy Holdings within the Viohalco industrial group, with headquarters in Marousi (Athens metropolitan area) and a primary manufacturing plant in Thisvi, Greece. The company produces linepipes for onshore and offshore oil and gas, hydrogen transportation, carbon capture and storage (CCS), demanding service environments (sour, arctic), OCTG casing and tubing, structural hollow sections for construction, water transmission and piling pipes, and offshore wind foundations, supported by internal and external coating, concrete weight coating, double jointing, materials testing, and on-site port logistics. Manufacturing is built around four pipe mills (7" HFI, 26" HFI, 56" LSAW, and 100" SAWH) at Thisvi, with the addition of an LSAW facility in Hartlepool, UK acquired from Liberty Steel in March 2026 that doubled total manufacturing capacity. Corinth generates revenue almost exclusively through project-based tenders and multi-year framework agreements with a narrow set of large enterprise customers — primarily international oil and gas majors (Shell, BP, TotalEnergies, Equinor), European gas transmission system operators (Gasunie in the Netherlands and Germany), and large infrastructure projects such as Net Zero Teesside Power. Pricing is negotiated per project on the basis of pipe specification, diameter, steel grade, coating, length, and delivery terms, with no public price list; the December 2025 Gasunie framework alone carries a potential total value of €2.5 billion across an initial four-year period covering hydrogen, natural gas, CO2, and energy transition infrastructure.
