Composite Hoses
RADCOFLEX: Composite Hoses
Radcoflex products are used extensively throughout many industries for a wide variety of applications including the conveying of materials and gases, mechanical protection, pipeline movement control and vibration absorption.
Composite Hoses Assemblies
Hose styles & Selections
Composite hoses are manufactured on the mandrel wrapped principle. The hose consists of an inner wire spiral upon which layers of fabric and fi lm are wrapped, and bound with an external wire spiral. The tension between each other of the wire spirals gives the hose its pressure capability.
The heart of a composite hose is in the materials selection. Fabric and fi lm materials used include Polypropylene, Polyester and Polyamide. The wire helixes can be of galvanised steel, aluminium, stainless steel or polypropylene coated steel. The final selection of the materials depends upon the application for the hose. Composite hoses are classified under a group number which refers to their chemical resistance suitability. A copy of a Chemical Compatability Chart is available from Radcoflex upon request.
Standards and Tolerances
Radcoflex Composite Hoses are manufactured in accordance with generally recognised industry standards including European Standards EN 13765 and EN 13766, and Australian Standards AS 2117 and AS 2683, and Australian Institute of Petroleum Code of Practices. Our Composite Hoses are tested in accordance with International Standard ISO 1402, British Standard BS 5173 and Australian Standard AS 1180.
Alternate specifications
In addition to the standard Radcoflex branded hoses, we manufacture a range of other composite hoses such as Uroflex and Indiflex that meet the standards applicable to the local market in which they are supplied.
Hose Installation
Incorrect installation of a hose assembly will create stresses within the assembly and result in a premature failure. The following guidelines should be followed:
- hose assemblies must not be twisted either during installation or in use
- hoses must not be overflexed or bent into a smaller diameter than the specified minimum bend radius
- hose assemblies should be installed so that flexing always occurs in the same plane
- it is recommended that flanged assemblies have a floating flange on one end for easier
- installation and to reduce the possibility of twist
