W-Mr-rgyn. <br />Do not twist the hose assembly during <br />installation when aligning the bolt holes in a <br />flange or in mating up pipe threads. The <br />utilization of lap joint flanges or pipe unions will <br />minimize this condition. It is recommended that <br />two wrenches be used in making the union <br />connection: one to prevent the hose from <br />twisting and the other to tighten the coupling. <br />installation. <br />Always install the hose so that the flexing takes <br />place in only one plane — this being the plane <br />in which the bending occurs. <br />3. Avoid over bending. <br />The repetitive bending of a hose to a radius <br />smaller than the radius listed in the <br />specification tables for corrugated hose will <br />result in early hose failure. Always provide <br />sufficient length to prevent over -bending and to <br />eliminate strain on the hose. <br />hose assembly. <br />Always lift or carry metal hose to prevent <br />abrasion damage particularly to braided <br />corrugated hose. Store metal hose assemblies <br />away from areas where it can be subjected to <br />spillage, corrosive fumes or sprays, weld <br />splatter, etc. <br />5. Always support the piping. <br />A piping system which utilizes metal hose to <br />absorb movement must be properly anchored <br />and/or guided. Always support the piping to <br />prevent excessive weight from compressing <br />the hose and relaxing the braid tension. <br />Do... <br />• Follow any printed instructions included with the flexible <br />connector. <br />• Follow industry—recommended practices and use care <br />in handling and installing flexible connector. <br />• Install flexible connectors so that the bend is as close to <br />the center of the connector as possible. <br />• Observe the minimum bend radius as specified by the <br />connector manufacturer. <br />• Trial -fit threaded connections by hand, unmake and <br />then make permanent. <br />• Use a flexible connector of proper length to suit the <br />installation. <br />• Only wrench on the fitting hex flats as provided: <br />• Design the installation to allow for ground movement <br />after installation, such as settling or frost heave. <br />• Install the proper length connector to allow a 2 straight <br />run of hose at each end fitting. <br />• Use pipe wrenches on both mating hexes to avoid <br />twisting the hose. <br />• Keep hose free from all objects and debris. <br />• Handle and store connectors carefully prior to <br />installation. <br />• Check for leaks before covering the installation. <br />• Install in such a manner that the connector can be <br />removed. <br />• Make sure the pressure rating and flow rating of <br />connector is not exceeded. <br />r• ; <br />• Apply a wrench to a hose, collar or assembly. <br />• Twist hose assemblies during installation or when <br />aligning the bolt holes in a flange or when making up <br />pipe threads. <br />• "Pre—flex" a flexible connector to limber it up. <br />• Over—bending could cause damage and result in <br />leakage. <br />• Over—bend a flexible connector. A 45°-90° bend should <br />be sufficient to install any flexible connector. <br />• Install a flexible connector with the bend next to the end <br />fittings. This could cause damage and result in leakage. <br />• Lay the flexible connector on rocks or objects which <br />could puncture the hose and cause leakage. <br />• Attempt to stretch or compress a flexible connector to fit <br />an installation. <br />• Restrict flexibility by allowing connector to come into <br />contact with other components or equipment during <br />installation. <br />• <br />1-800-234-2566 <br />8040 NE 33m Drive / Portland, OR 97211 (503) 281-4673 Fax (503) 281-5845 <br />
