Assembly Installation (continued)Avoid over bending.The repetitive bending of a hose to a radius smaller thanthe radius listed in the specification tables for corrugatedhose will result in premature hose failure. Always providesufficient length to prevent over bending and to eliminatestrain on the hose.CorrectWrongRCorrectWrongAvoid sharp bends.Utilize sound geometric configurations that avoid sharpbends, especially near the end fittings of the assembly.Provide support.When installing the assembly in a horizontal loop, providesupport for the arms to prevent the hose from sagging.CorrectSupportWrongNo SupportSagging andsharp bendsDS-EN-1000 (05)800-232-3539 610-367-2260 Fax 877-647-4011 www.penflex.com sales@penflex.com 24pflex.catalog_090403.indd 244/6/09 6:04:46 PM
Assembly Installation (continued)Do not extend or compress axially.A piping system which utilizes metal hose to absorb movementmust be properly anchored and/or guided.Always support the piping to prevent excessive weight fromcompressing the hose and relaxing the braid tension.CorrectPipe hangerMotionWrongBraid relaxedPipe not supportedAxial compressionHandle with care.Avoid careless handling of the hose assembly. Always lift or carrymetal hose to prevent abrasion damage particularly to braidedcorrugated hose. Store metal hose assemblies away from areaswhere it can be subjected to spillage, corrosive fumes or sprays,weld splatter, etc.Do…• follow any printed instructions included with the flexibleconnector.• follow industry–recommended practices and use care inhandling and installing flexible connector.• install flexible connectors so that the bend is as close tothe center of the connector as possible.• observe the minimum bend radius as specified by theconnector manufacturer.• trial-fit threaded connections by hand, unmake and thenmake permanent.• use a flexible connector of proper length to suit theinstallation.• only wrench on the fitting hex flats as provided.• design the installation to allow for ground movement afterinstallation, such as settling or frost heave.• install the proper length connector to allow a 2” straightrun of hose at each end fitting.• use pipe wrenches on both mating hexes to avoid twistingthe hose.• keep hose free from all objects and debris.• handle and store connectors carefully prior to installation.• check for leaks before covering the installation.• install in such a manner that the connector can beremoved.• make sure the pressure rating of connector is notexceeded.Don’t…• apply a wrench to a hose, collar or assembly.• twist hose assemblies during installation or when aligningthe bolt holes in a flange or when making up pipe threads.• “pre–flex” a flexible connector to limber it up. Over–bending could cause damage and result in leakage.• over–bend a flexible connector. A 45°–90° bend should besufficient to install any flexible connector.• install a flexible connector with the bend next to the endfittings. This could cause damage and result in leakage.• lay the flexible connector on rocks or objects which couldpuncture the hose and cause leakage.• attempt to stretch or compress a flexible connector to fitan installation.• restrict flexibility by allowing connector to come intocontact with other components or equipment duringinstallation.DS-EN-1000 (05)800-232-3539 610-367-2260 Fax 877-647-4011 www.penflex.com sales@penflex.com 25pflex.catalog_090403.indd 254/6/09 6:04:46 PM
