HOSE MANUFACTURING DATA

STORAGE Detailed recommendations for storage of product are contained in BS 5244, 1986 (1991). Tables 1, 2 and 3 of this document are produced with the kind permission of BSI. Hose & Hose Assemblies Stored as Separate Items Before fitting, all hose assemblies should be subjected to visual examination for evidence of deterioration. The recommendation in Tables 1 and 2 apply to stored hoses and assemblies, depending on their age.

TABLE 1 TEST RECOMMENDATIONS FOR RUBBER HOSES AGE RECOMMENDATIONS

Up to 3 years Use without further testing 3 to 5 years Use after representative samples subjected to a

proof pressure test 5 to 8 years Use after representative samples subjected to

proof, impulse and burst pressure tests, and cold bend and electrical tests

Over 5 years Scrap NOTE 1: It is important that hose assemblies fitted to stored equipment should be filled with the operating fluid with which they will be used on that equipment. NOTE 2: It is highly recommended that hose assemblies fitted to stored equipment in conditions of extreme temperature, humidity or ozone concentration (strong sunlight) should be tested after 1 year according to the criteria stipulated for 3 to 5 year old assemblies.

ROUTING In general, routing should be such that bends lower that minimum bend radius or tensile loading of the hose assemblies must be avoided. The minimum bend radius is measured to the inside of the bent hose and the length of the assembly should be such that there is a 25mm long straight portion of the hose at the inlet to each end fitting. Where abrasion of the product is likely, consideration should be given to extra protection. This can be provided in the form of steel or plastic spring guarding over the external surface of the hose preventing exposure to damage. To this end, specific attention must be paid to the movement of the hose when operating between components of a hydraulic system which move relative to each other. It is advisable to ensure that hose is routed such that there is no bending of the hose within 25mm of the end fitting to which it is attached and that where possible, assemblies are not manufactured with swept elbows at either end. When deciding the routing of hose assemblies specific attention should also be paid to clipping and/or clamping hoses at appropriate points.

INSTALLATION Before attempting to connect a hose assembly it is essential to ensure that the joining surfaces are completely free from foreign matter and from burrs, flash or fins. Damage to these surfaces, especially where metal to metal cone connections are concerned, may result in leakage. Also, hose assemblies should have been cleaned internally to avoid any contamination entering the system which may be residue of the hose assembly manufacture.

PROBLEM POSSIBLE CAUSE & MISAPPLICATION

SOLUTION

Hose bursts on outside of bend and is out of shape.

Hose bent too tight in routing. Reinforcement opened up too much on outside bend.

Increase hose length, also may be able to use different end fittings, i.e. swept 90 instead of straight.

Coupling blows off end when under pressure.

Incorrect coupling used. Couplings not crimped to correct swage dimension. Coupling not fully inserted. Hose not correct skived. Hose too short, twisted or bent too tight.

Check hose coupling compatibility, check swage information. Does routing cause excessive stress on assembly.

Hose liner swells or deteriorates, blocking fluid flow or leaking

Hose liner is not compatible with fluid. Temperature may be a factor.

Before making assembly, identify fluids and temperature in use. Check compatibility.

Wire reinforcement is rusty at site of hose burst.

Hose cover broken by cutting, abrasion, extreme temperatures, chemical attack, improper cover skiving, internal gas caused by blisters.

Use hose guard, nylon sleeve, anti‐abrasive cover hose. Check temperature & fluid compatibility. Cover may require perforating.

NOTE: IN SOME INSTANCES, FAILURE MAY BE CAUSED BY PREVIOUS REPAIRS.



FACTORS AFFECTING SERVICE LIFE

Main Causes

* Excessive Pressure

* Abuse

* End of Working

Contributory Factors

* Installation

* Below recommended minimum bend radius

* Twisting

* Pulling

* Temperature extremes

* Vibration

* Chemical attack

* High velocity oil erosion (hose tube)

* Ageing (ozone)

* Incorrect angle orientation



DO’S AND DON’TS TO PROLONG HOSE LIFE

DO Always use Hydraulic & Offshore Supplies fittings together with

Hydraulic & Offshore Supplies approved hose.

DON’T Ever mix and match hose and couplings

from different sources. Make hose assemblies from Hydraulic & Offshore Supplies matched components to ensure compatibility and performance.

DON’T Cut out a piece from an existing

assembly to remove the “bad bit” and put a new coupling on. If a hose has failed it is likely that the reinforcement has passed its working life. First‐aid repairs are potentially lethal and invalidate any manufacturer’s guarantee.

DON’T Alter the pressure relief valve in your

hydraulic system without considering whether the increased pressure will exceed the recommended max working pressures of your hose assemblies. If it will, replace the hoses with more suitable assemblies.
