CARE & MAINTENANCE

STORAGE:


Rubber hose products in storage can be affected adversely by temperature, humidity, ozone, sunlight, oils, solvents, corrosive liquids, fumes, insects, rodents and radioactive materials. The following are the precautions to ensure longer life of the hose:


Hoses should be preferably stored in a cool, dark and dry place. Exposure to direct or reflected sunlight-even though windows- should also be avoided.

Please take care while using knives or sharp tools while unpacking the hose.

Hose should not be piled or stacked to such an extent that the weight of the stack creates distortions on the lengths stored at the bottom. In case of large bore hose, reinforced with wire and with end fittings, hose should be kept in straight condition without stacking over one another. Hose trans-shipped straight should be stored straight.

Rubber hose should not be stored near electrical equipment that may generate ozone. Uncovered hose should not be stored under fluorescent or mercury lamps which generate light waves harmful to rubber. Hose should be kept away from arc welders.

Items should be stored on a first-in, first-out basis, since even under the best of conditions; an unusually long shelf life could cause deterioration of certain rubber hoses.

GENERAL CARE AND MAINTENANCE OF HOSE


Hose should not be subjected to any form of abuse in service. It should be handled with reasonable care.

Hose should not be dragged over sharp or abrasive surfaces unless specifically designed for such service.

Care should be taken to protect hose from severe end loads for which the hose or hose assembly were not designed.

Hose should be used at or below its rated working pressure; any changes in pressure should be made gradually so as not to subject the hose to excessive surge pressure. Hose should not be bent beyond the designed bend radius.

Hose should not be kinked or be run over by equipment or vehicles viz. forklifts. In the case of the hose with end fittings-avoid sharp bends at nipples and end connections. Hose should not be pulled by its coupling. It can lead to a dangerous failure.

In handling large size hoses, hose dollies should be used whenever possible; slings or handling rigs, properly placed (apporx. every 10 feet), should be used to support heavy hose used in oil suction and discharge service. Large diameter hose should be lifted by the middle with ends hanging down. This can damage the hose's internal reinforcement. Where hose is exposed to excessive wear at one spot, add an extra protective cover, such as a nylon sleeve or a pad.
