Rubber Air Hose

The characteristics of rubber tube: physiological inertia, UV resistance, ozone resistance, high and low temperature (80 ~ 300 ℃), high transparency, strong resilience, compression resistant permanent non deformation, oil resistance, stamping, acid and alkali resistance, abrasion resistance, refractory, voltage resistance and electrical conductivity.


Maintenance and use of Rubber Air Hose


1. Correct use of air rubber tube

It is very important to determine the length of rubber hose you need, and we also need to check whether the use conditions of the rubber hoses are suitable for work environment at the same time. Make sure that the right rubber air hose you purchase from Somax is our duty. The work pressure and the suction value should be carefully determined. In particular, it should be noted that sudden pressure change or peak pressure exceeds the maximum allowable value, which will greatly shorten the service life of the rubber tube. The ends of the rubber tube can not be immersed in the conveyed material continuously.


2. Installation of rubber tube for use

If you install the rubber tube when the bending radius is less than the specified minimum value, the service life of the rubber tube will be greatly reduced. So before installation, you are advised to use information to consult, especially rubber pipe bending radius information.


3. Maintenance of air rubber tube

Cleaning: after use, it is recommended that you empty the hose. If necessary, it should be cleaned.

Inspection: after every use, rubber pipes must be inspected to ensure that there is no structural damage.

Pressure: if the rubber pipe is subjected to severe pressure when it is in use or the outer layer of rubber tube will be in contact with the liquid transported for a long time, hydraulic test is recommended.


Proposal for storage of rubber hose

Because of the natural properties of rubber, the physical properties and performance levels of all rubber products will change. The changes usually occur over time depending on the type of rubber used. But it can also be accelerated by several factors or combinations of factors. Other materials used to reinforce rubber hose pipes may also be negatively affected by improper storage conditions. The following recommendations include a series of preventive measures to prevent maximum aging of objects in storage.


1. Storage time

Use the rotation plan system to shorten the storage time of air rubber tube. If you can't avoid long time storage and can't follow the following suggestions, you should thoroughly inspect the rubber tube before use.


2. Physical storage conditions

The storage of air rubber tubes must avoid mechanical pressure, including transition stretching, tightening or deformation, avoiding contact with sharp or sharp objects. Rubber tubes are preferentially stored on suitable scaffolds or placed on dry ground. The rubber tube of the coil package must be placed horizontally, and the rubber tube should not be stacked. If stacking is unavoidable, stacking height should not cause permanent deformation of the rubber pipe below. As a rule, try to avoid rubber pipes around the posts or hooks. If the rubber hose is shipped on a straight pipe, it is recommended to store horizontally instead of bending it.


3. Contact with other materials

Air rubber tubes must not be exposed to solvents, fuels, oils, lipids, unstable chemicals, acids, disinfectants, or general organic liquids. Moreover, any kind of rubber will be damaged after contacting with some materials or mixtures, including manganese, iron, copper and its alloys. Rubber pipes should avoid contacting with PVC (PVC) or wood or cloth impregnated with mixed oil.


4. Temperature and humidity

Recommended storage temperature: 10 ~ 25 ℃. Note: no air hose should be stored at temperatures above 40 degrees Celsius or below 0 degrees Celsius. Special caution should be taken when moving the rubber hose below 15 degrees Celsius. Rubber hose shall not be stored in the heat source attachment, and the relative humidity should be no more than 65%.


5. Heat source

The temperature limit stated at fourth points must be observed. If it can not be done, insulation shall be used to protect rubber tubes from heat source.


6. Light

The storage room used for storing air rubber tubes should be kept dark, especially avoid being irradiated by direct sunlight or strong artificial light. If the storage room has windows or any openings covered by glass, it should be shaded.


7. Oxygen and ozone

Air rubber tubes should be properly packaged or stored in closed containers to avoid exposure to air. It is not allowed to place ozone release equipment in storage room. Ozone has a strong effect on all rubber products.


8. Electric field and magnetic field

The storage room should avoid any possible electric or magnetic fields, including exposure to high-voltage cables or high-frequency generators.
