Flanged Connector Flexible Metal Hose are great for restraining vibrations, which can protect sensitive instrumentation, limit mechanical fatigue, and prevent loosening of bolt connections. The nominal pressure ratings of flexible metal hose vary according to type, material and size. Pressure is affected by many other factors such as temperature, pulsating conditions and bending stresses, under actual working conditions.
The flexibility of metal hose is achieved by means of the elastic behavior of the corrugation profile. When the hose is bent, the outer corrugations separate while the inner corrugations are squeezed together. The flexibility, bending behavior and pressure stability of corrugated hoses depend on the selected profile shape. While flexibility increases with an increase in profile height and a decrease in corrugation spacing, pressure resistance decreases. The frequently required semi-flexible bending behavior is achieved by flat profiles. Depending on the use of the hose, special application-specific profile shapes can be custom-made. The fittings are attached by welding, silver brazing, soldering or other by other mechanical means, depending on the type of hose.
