CARE AND MAINTENANCE OF HOSE HOSE CLEANING There are many different methods used to clean hose assemblies. An apron, safety glasses or face shield, rubber boots and gloves should be worn to help protect the person doing the cleaning from potential injury. Some suggested methods for select hoses in this catalog are listed below. Which method to use and how often cleaning should be performed is based on the following: ■ Type of hose ■ Residual material in the hose ■ Cleanliness requirements for the application ■ Cleaning facilities available ■ Consideration for disposal of the residual material and cleaning solutions(s) ■ Requirements for special applications such as foods, pharmaceuticals, etc. SOLUTION RECOMMENDATIONS 1. Cleaning solutions should be chosen that will dissolve or remove the residual material without damaging the hose assembly. 2. A dilute solution of soap in water can often be sufficient. CAUTION – Some chemicals, such as concentrated acids or bases, can react with water releasing heat and byproducts, and possibly splatter. 3. Consult the MSDS of the material being cleaned to identify potential cleaning solutions. 4. After identifying potential cleaning solutions, check Chemical Resistance Table in this catalog for compatibility with hose tube and cover. 5. Non-compatibility of a cleaning solution can cause damage to the hose. FLUSHING OR IMMERSING IN A CLEANING BATH 1. Do not exceed the maximum working pressure or temperature for the hose. 2. The cover of the hose should also be washed or wiped to remove any residual material. STEAM CLEANING 1. Steam cleaning is NOT generally recommended. High temperatures can accelerate aging of a hose and shorten service life. 2. Do not exceed the maximum temperature rating of the hose. Doing so can cause defects such as tube de-lamination (reducing tube to reinforcement adhesion), tube cracking or tube flow leaving thin spots. 3. Never use superheated steam. This will exaggerate the potential damages noted above. Only “open-end” 50 psi steam should be used. 4. If the hose has blockage, remove it before introducing steam. 5. If the steam source has a wand attached, use caution inserting the wand so that physical damage to the hose is not caused. Sharp edges on the wand can cut the tube, and thin spots could occur where the hot wand contacts the tube. RECOMMENDED CLEANING OF CHEMICAL HOSE 1. Drain the hose after each use. 2. Flush with water or other neutralizing cleaning solution. 3. Properly dispose of drained fluid and cleaning waste. 4. Between uses, store the hose in a clean, dry environment away from sunlight. 5. Avoid cross contamination. Dedicate a hose to handle a specific chemical. RECOMMENDED CLEANING OF FOOD HOSE 1. Drain the hose after each use. 2. Flush with water or other cleaning solution. 3. Properly dispose of drained material and cleaning waste. 4. Between uses, store the hose in a clean, dry environment away from sunlight. 5. Avoid cross contamination. Dedicate a hose to handle a specific food material. To increase hose life it is always best to drain hose after each use. . GATES INDUSTRIAL HOSE PRODUCTS 32 www.gates.com
