Pumps and high-pressure components require BÖHLER steels and alloys 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.
Pumps and high-pressure components in the oil & gas and Chemical Process Industry (CPI) are exposed to extreme operating conditions, including very high pressures, temperature variations, and aggressive media such as sour gases, hydrocarbons, and chemical process fluids. These demanding environments require materials with outstanding mechanical strength, excellent corrosion resistance, and resistance to stress corrosion cracking and hydrogen embrittlement. In addition, components must provide high fatigue resistance, dimensional stability, and reliable sealing performance over long service intervals under cyclic loading and pressure fluctuations.
BÖHLER high-performance steels and alloys are specifically engineered to meet these challenges. Advanced quenched and tempered steels, stainless steels (austenitic, duplex, and precipitation-hardened), and high-alloy nickel-based materials offer an optimized balance of strength, toughness, and resistance to corrosive and high-pressure environments. Produced using advanced melting and refining technologies, BÖHLER materials ensure exceptional cleanliness, low inclusion content, and homogeneous microstructures, significantly improving fatigue life and operational reliability. Key quality features include strict control of chemical composition, certified traceability, and precisely controlled heat treatment processes. Comprehensive testing, including pressure resistance, corrosion evaluation, and non-destructive inspection, ensures compliance with stringent oil & gas and CPI standards. BÖHLER materials enable safe, efficient, and long-lasting pump and high-pressure component solutions.
BÖHLER A911SA es un acero inoxidable ferrítico-austenítico del tipo 25 % Cr con un PREN mínimo de 40. Ofrece una excelente resistencia a la corrosión general, al agrietamiento por corrosión bajo tensión, a la fatiga por corrosión, a la corrosión por picaduras, a la corrosión por hendiduras y a la corrosión por erosión, y posee propiedades de resistencia mecánica muy elevadas. Sin embargo, contiene menos cobre que otros aceros inoxidables súper dúplex, pero en su lugar se le ha añadido deliberadamente tungsteno, lo que, según se afirma, mejora selectivamente la resistencia a la corrosión. Buena soldabilidad, no es necesario el tratamiento térmico posterior a la soldadura. Temperatura máxima para periodos de servicio prolongados: 280 °C (535 °F) / (300 °C/570 °F posible para periodos cortos). Condición de la superficie para una resistencia óptima a la corrosión: decapada o mecanizada. Componentes en plantas marítimas, de aguas residuales, de desalinización de agua de mar y químicas con medios agresivos que contienen cloruro, por ejemplo, intercambiadores de calor, piezas separadoras, componentes de compresores y bombas, álabes de turbinas.
