Tubular products, flanges, and fittings require BÖHLER steels with high strength and corrosion resistance. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable oil & gas and CPI performance.
Tubular products, flanges, and fittings used in the oil & gas and Chemical Process Industry (CPI) are critical components for fluid transport and pressure containment under harsh operating conditions. These components are exposed to high pressures, temperature variations, and aggressive media such as CO₂, H₂S, chlorides, and chemical process fluids. Material requirements are therefore focused on high strength, excellent corrosion resistance, and resistance to stress corrosion cracking, hydrogen-induced cracking, and fatigue under cyclic loading. Reliable weldability and dimensional stability are also essential to ensure leak-tight and safe system performance over long service lifetimes.
BÖHLER high-performance steels and alloys are specifically engineered to meet these demanding requirements. Advanced low-alloy and quenched and tempered steels, as well as corrosion-resistant stainless steels including austenitic, duplex, and precipitation-hardened grades, provide an optimized balance of toughness, strength, and environmental resistance. Produced using advanced melting and refining technologies, BÖHLER materials ensure superior cleanliness, low inclusion content, and homogeneous microstructures, enhancing reliability and service life. Key quality features include strict chemical composition control, certified traceability, and precisely controlled heat treatment processes. Comprehensive testing, including corrosion evaluation, mechanical verification, and non-destructive inspection, ensures compliance with industry standards. BÖHLER materials enable safe, durable, and high-performance tubular solutions.
BÖHLERL718 API (UNS N07718) is a high-strength, corrosion-resistant nickel-chromium-iron-molybdenum material with excellent corrosion resistance, especially in H2S and CO2 environments. The alloy is age-hardenable due to the addition of niobium, titanium and aluminium. BÖHLER L718 API is recognised by the oil industry for its simple and cost-effective production in combination with good tensile, fatigue, creep and fracture strength and is used in a wide range of applications in this sector. BÖHLER L718 API has excellent weldability and is resistant to cracking after welding. The material can be used at high temperatures. BÖHLER L718 API is available in the NACE/API 6A CRA versions with a minimum yield strength of 120/140 ksi and also in the high-strength version with 150 ksi. All hardness grades are suitable for sour service and can be used for pressurising and pressure-controlling equipment in corrosive environments. Typical applications include packers, pumps, connectors and fasteners as well as gate valves, throttle spindles, pipework hangers and fire safe valves, but also a wide range of downhole and completion components, nuclear and surface applications.
