CARE, MAINTENANCE AND STORAGE (continued)
7. When liquids such as gasoline, oil, solvent or other
hazardous fluids are used as the test fluid, precautions must be
taken to protect against fire or other damage should a hose fail
and the test liquid be sprayed over the surrounding area.
The Rubber Manufacturers Association has published separately
a series of Hose Technical Information bulletins describing
Maintenance, Testing and Inspection recommendations.
Reference should be made to the current RMA Catalog of
Publications to determine the availability of the latest edition.
Bulletins published as of January 2003 include the following:
Publication No.
IP 11-1-Steam Hose
IP 11-2-Anhydrous Ammonia Hose
IP 11-4- Oil Suction and Discharge Hose
IP 11-5-Welding Hose
IP 11-7-Chemical Hose
IP 11-8- Fuel Dispensing Hose
Storage
Rubber hose products in storage can be affected adversely by
temperature, humidity, ozone, sunlight, oils, solvents, corrosive
liquids and fumes, insects, rodents and radioactive materials.
The appropriate method for storing hose depends to a great
extent on its size (diameter and length), the quantity to be
stored and the way in which it is packaged. 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. Since
hose products vary considerably in size, weight and length, it
is not practical to establish definite recommendations on this
point. Hose having a very light wall will not support as much
load as could a hose having a heavier wall or hose having a
wire reinforcement. Hose which is shipped in coils or bales
should be stored so that the coils are in a horizontal plane.
Whenever feasible, rubber hose products should be stored
in their original shipping containers, especially when such
containers are wooden crates or cardboard cartons which
provide some protection against the deteriorating effects of oils,
solvents and corrosive liquids; shipping containers also afford
some protection against ozone and sunlight. Certain rodents
and insects will damage rubber hose products, and adequate
protection from them should be provided.
Cotton-jacketed hose should be protected against fungal
growths if the hose is to be stored for prolonged periods in
humidity conditions in excess of 70%.
The ideal temperature for the storage of rubber products ranges
from 50°F to 70°F (10°C to 21°C) with a maximum limit of
100°F (38°C). If stored below 32°F (0°C), some rubber products
become stiff and would require warming before being placed in
service. Rubber products should not be stored near sources of
heat, such as radiators, base heaters, etc., nor should they be
stored under conditions of high or low humidity.
To avoid the adverse effects of high ozone concentration, rubber
hose products should not be stored near electrical equipment
that may generate ozone or be stored for any lengthy period
in geographical areas of known high ozone concentration.
Exposure to direct or reflected sunlight, even through windows,
should also be avoided. Uncovered hose should not be stored
under fluorescent or mercury lamps which generate light waves
harmful to rubber.
Storage areas should be relatively cool and dark,
and free of dampness and mildew. Items should be
stored on a first-in, first-out basis, since even under
the best of conditions, an unusually long shelf life
could deteriorate certain rubber products.
