Lighter high-pressure hose adds reliability to nacelles

By KRemington | July 6, 2010

New Compact Spiral hose offers unprecedented 5,000 and 6,000-psi capability in a design that delivers measurably more flexible routing, installation, size, weight and service life advantages compared to conventional SAE spiral hose. New 787TC (5,000 psi) and 797TC (6,000 psi) Compact Spiral hose is available in sizes -8, -10, -12 and -16. Both hose lines will be extended at a future date to include larger sizes. A few features include greater flexibility, smaller O.D., and tighter bend radius. The company engineered a new high-performance inner tube that made it possible to refine, redesign and significantly reduce overall hose construction. The hose has 1/2 the bend radius and a nearly 30% smaller O.D. than conventional SAE spiral hose. It also requires 1/3 less effort to bend. The small bend radius reduces the total amount of hose needed by 20 to 55% depending on application. Compact Spiral is also easier to route and install, which saves time and reduces effort. More hose can also be routed into tight quarters where larger diameter, less flexible hoses simply would not fit. Furthermore, customers can “jump up” to a larger hose size for better flow characteristics in their hydraulic system while maintaining an O.D. similar to the smaller hose that was previously installed (for instance, the O.D. of a -12 size Compact Spiral hose equates to the O.D. of a -10 size comparable SAE hose).

The hose has been tested to 2,000,000 impulse cycles, twice the ISO 18752-DC standard and four times SAE requirements.

The hose weighs up to 26% less than standard spiral hose, making up tower climbs easier, and reducing shipping and packaging costs.
