Local execution. TBX Nexxia supports customers from early technical definition through manufacturing, delivery and installation. ### High-performance materials and connections Advanced CRA grades combined with proven premium connection technology for demanding well conditions. ### Dedicated CRA OCTG manufacturing at scale Large capacity across Spain and Abu Dhabi, with integrated steelmaking. ### Faster, more predictable deliveries Our Melt to Well integrated CRA OCTG manufacturing allows significantly faster deliveries than industry standards. ### A comprehensive supply solution Competitive supply supported by locally deployable storage, rig preparation and field services, tailored to each project. Delivery matters Where complex OCTG becomes deliverable. In demanding OCTG projects, delivery starts long before the product reaches the well. From material selection, connection definition and qualification to manufacturing, logistics and field execution, TBX Nexxia turns complex requirements into solutions that can be delivered with confidence. Technical solutions. Excellence in execution. Reliable delivery, guaranteed. Engineered for demanding applications ## Engineered for the world's most demanding wells Exploration & Production ### Production tubing and casing widely used and tested in the most demanding exploration and production wells. CRA tubular solutions are designed and proven for highly corrosive, HP/HT and deepwater oil & gas wells, where material selection, connection performance and long-term well integrity are critical. SENTINEL® Prime has been specifically designed and tested on CRA materials to withstand these extreme operating conditions. Talk to our technical team Enhanced Oil Recovery & Water Injection ### Engineered for high-pressure water injection in demanding reservoir conditions. CRA tubular solutions provide enhanced resistance to chloride-induced corrosion, pitting and stress corrosion cracking in seawater and treated-water injection environments. Using duplex, superduplex and nickel-based alloys, TBX Nexxia helps ensure reliable injection performance, long-term well integrity and reduced lifecycle costs in EOR operations. Talk to our technical team Carbon Capture, Utilization and Storage ### TX25NP-125 Super Duplex and SENTINEL® Connections, tested for CO₂ injection with impurities. SENTINEL® Connections have been tested as per specific CCUS well conditions, including cryogenic thermal and pressure cycling.
