Metal Hose Assemblies

Whatever the application, environment, pressure or flex requirements, AmniTec can provide a steel hose assembly that will measure up to the demands made.  Hose assemblies are designed, manufactured and rigorously tested to match exact operating conditions, with precision and utmost reliability.

AmniTec metallic hose assemblies are well proven in a wide variety of demanding industries including nuclear, gas, electricity, defence, petrochemical and automotive. Whether the requirements are for exceptional flexibility, the protection of sensitive cables, an insulated hose, colour coded hose or multi-layer hoses encapsulated in an outer hose. AmniTec can match those needs exactly. Special anti-scuff protection, hand protectors and spring guards are also available.

Purpose

AmniTec annular metal hose assemblies are made up of three major parts: metal hose, overbraid and end fittings. Assemblies achieve several objectives in pipework design: to absorb vibration, suppress rigid pipe transmitted noise, accommodate reciprocating and flexing movement and adjust or correct for minor misalignment.

Hose

The steel hose body provides the flexible and pressure tight core of the assembly. The pitch of the hose can be varied to achieve performance requirements in both flexibility and pressure rating.

Braid

The object of the braid is to prevent elongation. Braid is made of stainless steel wire, woven such that the line pressure produces braid tension which provides radical and axial constraint. Multiple braided assemblies accommodate higher pressures.

End fittings

This is the means by which the custom-designed assembly is attached into the pipework system. Our normal standard is for fixed male or female connectors or flanges. These are available in both stainless steel and carbon steel dependant upon the media. Our experience is demonstrated by our vast a stock of end fittings for specific purposes.

Testing

All hose assemblies are tested prior to despatch to meet Amnitec's product quality standards.
