When the hose is removed for scheduled maintenance testing the fire sleeve is to be removed and replaced with a new sleeve without dismantling the end fittings. One sample of each new type of hose assembly is to be subjected to a qualifying hydrostatic pressure test of the complete assembly, including end fittings, of five times the maximum system working pressure or the hose assembly proof pressure, whichever is higher apart from hyperbaric hoses.
Tags shall not be removed from hyperbaric hoses under any circumstances. Develop and implement a plan to resolve loss of Naval Engineering. Page 12 of 16 h.
Page 14 of 16 System with the release of ABR – the Navy. In manned spaces they should be replaced no later than 12 years after installation and internally inspected in accordance with the appropriate planned maintenance requirement during each 6 year period.
Ensure that pipe and hose assembly supports are intact and that there is no distortion or other damage and that all fasteners are tight. Documents Flashcards Grammar checker. Observation that equipment meets performance criteria upon setting to work. When accepting hoses with shelf life over 4 years ships should consider the arb of condemning the hose for disposal against the reduction in service life.
The Naval Technical Regulatory System. Therefore items suppled via the ADF supply chain can be assumed xbr comply with material requirements and the only certification required is evidence that the correct item has been demanded and supplied.
Testing and Replacement of Flexible Piping Devices
All flexible hoses integral to the GTRB are to be subjected to a proof test when the engine undergoes an overhaul ie depot level repair. Irrespective of the results obtained from any other inspection, any of the following conditions shall be cause for rejection of rubber hoses: Metal Hose Rejection The RAN’s technical regulation system requires that evidence of safety be: The life cycle of a rubber hose contains two separate elements.
For hyperbaric applications, only approved hoses shall be used. Endorsement indicates that technical risk has been assessed, and that the endorser is satisfied that any risk is being appropriately managed. Working in Confined Spaces regulations, the Contractor shall provide. Reference A is cancelled and replaced by this Technical Directive. They do not overlap. Sustainment Management in the Royal Australian Navy. The outer rubber layer of a hose assembly.
Testing and Replacement of Flexible Piping Devices
Ensure that the tube and cover are anr and contain no cuts, cracks or abrasions. Cuts and abrasions, which expose glass fibre, shall be cause for rejection. OEM hoses may be replaced with hoses of the same material type, to an equal or higher standard, if the installed hoses have not been a problem, subject to CME or 64922 DAR concurrence. Spare rubber hose assemblies, whose shelf life has expired, may be used when exigencies of service dictate. Other authorised specific system instructions.
Spare Hose Assemblies Service life begins from the date of installation for hoses installed between major refits and from a date agreed upon between the relevant authority and the contractor for installation during major refits and construction.
The classification for air pressure categories are as defined at Chapter Page 6 of 16 23 of ABR or reference B, for hyperbaric hoses: On completion of ar satisfactory visual examination, subject the hose assembly for hyperbaric hoses refer to para d.
Further advice should be sought from CME or other DAR before using spare rubber hose assemblies whose origin and cure dates are unknown. The required pressure will be determined by one of the following, in order of precedence: The specified work having been undertaken satisfactorily as indicated by written reports. Evidence of large 64922 due to improper, or lack of, supports. Once put into service, the repaired hose assembly shall then be routinely inspected iaw the 642 maintenance practice and the tape renewed if it displays fraying or unbonding.
A preliminary version of a hose assembly developed for a new application or abrr change from one type of fitted hose to another type, eg PTFE to rubber, or from fixed piping to hose.
In such cases the hose assembly can be assumed to have a remaining service life of eight years. ADFLMs have a responsibility to ensure that an appropriate certification plan is put in place to ensure items meet procurement specification.
There are occasions when a hose assembly may need to be manufactured in lieu of acquisition through DMO. For hyperbaric hose identification requirements, first consult the approved hose configuration drawing. The objection to painting hoses is that it not only hides the condition of the outer cover during examination but a build up of paint layers will slowly destroy the noise attenuating properties of the hose. The definition of arb words and phrases used in discussing hoses, end fittings and hose assemblies is as follows: The prototype hose assembly that is subjected to a qualifying pressure that is higher than the proof pressure is not to be used as a working hose assembly.
Periodic visual inspections shall be made of all installed flexible hose assemblies for signs of physical damage. For critical systems the service life is a maximum of 12 years.
