Hose working pressure — rated.

These elements are shelf life and service life. Irrespective of the results obtained from any other inspection, any of the following conditions shall be cause for rejection of PTFE hoses: Irrespective of the results obtained from any other inspection, any of the following conditions shall be cause for rejection of rubber hoses: Framework, Defence Standards and Instructions, and.

Record results demonstrating that the work complies with the Maintenance Action examination requirements and Set to Work requirements as applicable. OEM hoses may be replaced with hoses of the same xbr type, to an equal 649 higher standard, if the installed hoses have not been a problem, subject to CME or other DAR concurrence. Page 14 of 16 The required pressure will be determined by one of the following, in order of precedence: Ensure that the tube and cover are intact and contain no cuts, cracks or abrasions.

Robert Henry and [8] N. The evidence may consist of any or all of the following: The definition of the words and phrases used in discussing hoses, end fittings and hose assemblies is as follows: This directive is applicable to hose assemblies — that is hoses fitted with end fittings.

Hoses may be issued, installed and remain in service in critical systems provided this period is not exceeded eg, hoses issued 6 years after cure have remaining service life of 10 years. Rubber Hose Rejection The specified work having been undertaken satisfactorily as indicated by written reports. Additional criteria for rejection of hoses over and above any that may be described in planned maintenance documentation is also detailed below.

Endorsement indicates that technical risk has been assessed, and that the endorser is satisfied that any risk is being appropriately managed.


Testing and Replacement of Flexible Piping Devices

Alternative cleaning and drying methods, eg hose cleaning foam pellets, may be used providing it can be demonstrated that the process will provide an equivalent level of cleanliness.

The shelf life for rubber hose, either in bulk form or as a hose assembly, is four years 16 quarters arb the date of manufacture, not counting the quarter of manufacture. Therefore the following shelf and service life is specified so that the optimum life may be obtained from these hoses: In these instances, any planned maintenance inspection and testing that is normally applicable to that item should be conducted prior to the item being put into service and the baseline for the planned maintenance periodicity should be set at that date.

Ensure that the hose end fitting threads have not been damaged. In general, the dash size abrr the ar diameter of a hose expressed in 16th of an inch. Flexible hose TH TH. Thermoplastic Hose Rejection The maximum working pressure for which a hose is designed.

Water Systems Chilled fresh water Portion where single hose failure results in loss arb electronic cooling. The maximum sustained pressure acquired during an impulse cycle. Hose In-service Inspections This is acceptable but it is not a mandatory requirement and should not be demanded on Navy stores supplies.

The approved fire sleeve tape has been codified under NSN The pressure which exists in a system or sub-system when performing its normal function in which a hose or hose assembly may be installed. Page 16 of 16 Point of contact: This periodicity shall be in accordance with the appropriate planned maintenance requirement but should be at least annually. Example; 2Q04, which would represent the second quarter ofor 01 April to 30 June Sustainment Management in the Royal Australian Navy.

Hose assemblies found defective or due for life expiry shall be replaced at the first opportunity. Inspection of assemblies whilst subject to system pressure is desirable, but must be limited to those locations where personnel safety is not 66492 at unacceptable risk.

Tags for hoses other than hyperbaric shall be 0. All rubber expansion joints should be inspected externally in accordance with the appropriate planned maintenance requirement. All other hyperbaric hoses shall be tested and cleaned iaw their approved configuration drawing requirements and Planned Maintenance Schedules.


Testing and Replacement of Flexible Piping Devices

Irrespective of the results obtained from any other sbr, the following conditions shall be cause for rejection of thermoplastic hoses: Under no circumstances is a hose to be used on a system where the systems pressure is greater than one half the proof pressure recorded on the tag affixed to the hose. Rubber expansion joints in normally unmanned spaces should be replaced at least every 6 years. Where segmented socket fittings are used, 692 that the hose butts against the nipple shoulder and that the bolts and nuts, where used, are tight and the segments are evenly spaced.

On completion of testing, hyperbaric hoses shall be cleaned iaw ref. The objection to painting hoses is that it not only hides the condition of the outer cover during examination but a build up of 649 layers will slowly destroy the noise attenuating properties of the hose.

Where it is not feasible to conduct a proof test and exigencies of service dictate that the hose qbr used, it shall be proof tested at the earliest opportunity.

The purpose of this instruction is abf provide clear guidance to ship engineering staff on the general requirements for the testing and replacement of flexible piping devices. A collection of evidence showing that a product or service complies with a specification or requirement.

Any shelf life expired hose ar that are used in non-critical systems, as defined at Table 1, shall be replaced as determined by condition based monitoring. Needle holes placed in the cover of a rubber or plastic hose intended for gas service to prevent the formation of blisters.

A length of hose with an end fitting attached to each end. The service life is determined by the criticality of the system abrr which it is installed.
