Pressure
Be sure to use the hose within the recommended temperature and pressure range. Rubber hose pipe expands and contracts with internal pressure, so cut the hose slightly longer than needed. When applying pressure, slowly open/close any valves to avoid pressure shock.
Fluid
Use a rubber hose pipe that is suitable for the conveyed fluid.
Bending
Use the rubber hose pipe under conditions above its minimum bending radius, otherwise, the hose may break and reduce pressure resistance. When using powder and granule, it may cause easy wear depending on the condition, so enlarge the bending radius of the hose as much as possible. Do not use it in an extremely bent state near metal parts (joints), and try to avoid extreme bending near metal parts. This can be avoided by using elbow fittings and other methods. Do not move the installed rubber hose pipe randomly, especially avoid causing force or excessive bending at the hose joint during the moving process.
Other: Do not let the rubber hose pipe directly contact or approach open flames, and do not use the vehicle or press the hose with any object.
Pre-use check: Before using the rubber hose pipe, check for any abnormalities in appearance (external injury, hardening, softening, discoloration, etc.). Regular inspection: During the use of the rubber hose pipe, be sure to carry out monthly inspections.
Sanitary-grade rubber hose pipe is quite special, and so is the cleaning process. Before using a sanitary-grade rubber hose pipe, it must be rinsed internally to ensure the ideal sanitary condition during installation and use. Clean the inside of the hose before the first use by filling the hose with hot water at 70℃-80℃ for at least 10 hours, and then draining the hose. The recommended cleaning methods are as follows:
Hot water with a maximum temperature of 90℃ or steam with a maximum temperature of 110℃ (cleaning time within 10 minutes) or 130℃ (high-temperature cleaning for 30 minutes) for this type of rubber hose pipe, depending on the recommendation of the product engineer.
Nitric acid (HNO3) or nitric acid-containing cleaning, maximum concentration: 0.1% at 85℃, or 3% at room temperature.
Chlorine (CL) or chlorine-containing cleaning, maximum concentration: 1%, maximum temperature: 70℃.
Sodium hydroxide (NaOH) or sodium hydroxide-containing cleaning, maximum concentration: 2% at 60-80℃ or 5% at room temperature.
