Swagelok® Medium-Pressure Tube Fittings (FK Series)
The two-piece design of Swagelok® FK series medium-pressure tube fittings reduces installation time and lowers maintenance costs. These fittings provide a vibration-resistant, leak-tight, and robust connection that protects workers and the environment.
FK series fittings have revolutionized fluid connections in downhole oil and gas exploration applications and streamlined R&D fluid systems requiring frequent reconfiguration. These fittings also aided in the development of the hydrogen economy through leak-tight hydrogen fluid connections that meet the requirements of EC-79 for performance at pressures up to 700 bar [10 150 psig] in hydrogen applications.

The design of Swagelok FK series fittings consists of a female fitting body and a preassembled cartridge containing the male nut and color-coded front and back ferrules on a disposable arbor. The preassembled cartridge ensures correct ferrule orientation, visual confirmation of ferrule presence, and proper installation into the female body. These fittings are available in 316 stainless steel, alloy 2507, and alloy 625. The body/cartridge combination allows for easy installation using either specified turns or torque using standard tools.

Caso práctico: Operador de Petróleo en Alta Mar
Vea cómo Swagelok ayudó a un operador petrolero a reducir el tiempo de instalación y a mejorar el rendimiento general, cambiando las conexiones de cono y rosca existentes por los racores Swagelok serie FK.
La Investigación Conjunta de Empa y Swagelok Impulsa el Desarrollo de Innovaciones en el Transporte con Hidrógeno
Los Laboratorios Federales Suizos de Ciencia y Tecnología de los Materiales (Empa) y Swagelok están explorando la viabilidad de las soluciones de transporte basadas en el hidrógeno. Un reciente avance en la investigación derivado de nuestra colaboración incorporó los racores Swagelok serie FK dentro de la solución de hidrógeno de Empa. El uso de los racores serie FK en lugar de los tradicionales racores para tubo Swagelok facilitó significativamente la instalación, a la vez que mejoró la estanqueidad, la fiabilidad y la seguridad.
Racores para Tubo de Media Presión Serie FK
Desde la construcción inicial y la puesta en marcha hasta la operación y el mantenimiento diario, se pone una gran atención a la reducción de los costes totales del ciclo de vida. Los racores serie FK pueden reducir los costes de mantenimiento y ofrecer una alta fiabilidad, reduciendo el tiempo de inactividad del sistema cuando se siguen los procesos de montaje adecuados. Estos racores también pueden ayudar a reducir el impacto medioambiental mediante la reducción de fugas, así como a mejorar la seguridad general protegiendo su sistema contra la corrosión.
