Quality problems regardless of that industry has always been a big problem, silicone hose is no exception, sometimes we are in the process of use, there will be bursting, which seriously affects the use of the effect, a part of the reason may be the cause of poor quality products, of course, there are other reasons are worth exploring, so what are the reasons that lead to silicone tube bursting?
Lead to silicone tube burst 5 major reasons
- The pressure is too high
The silicone tube is limited to withstand pressure, if the pressure is too high, it will lead to silicone tube burst. - High temperature
The silicone tube temperature range is -40 ℃ ~ 200 ℃, if the temperature is too high, it will lead to the silicone tube aging brittle, thus bursting. - Chemical corrosion
Hydraulic systems due to power loss and heating of the oil, coupled with the influence of the outside air temperature, can make the oil temperature rise sharply. The higher the temperature of the oil, the easier the rubber aging, elasticity deterioration, strength and sealing performance decline, the hose will soon burst. Therefore, in the operation, when the hydraulic system temperature rise is too high, too fast, should promptly find out why, to be excluded. - Silicone tube selection, installation is unreasonable.
In the replacement of large-diameter high-pressure silicone tube, the length of the selected high-pressure silicone tube, the number of layers of steel wire, the shape and size of the joints should be reasonable, and should minimize the degree of bending of the high-pressure silicone tube; in the tightening of the joint nut, do not make the silicone tube produced by the distortion of the excessive bending and distortion will greatly reduce the service life of the high-pressure silicone tube; some of the friction prone to the parts of the friction should be taken to protect against high pressure silicone tube Burst due to wear and tear. - Aging
Silicone hoses in the process of use will gradually age, aging will lead to silicone tubes becoming brittle, thus bursting.
Measures to prevent silicone tube burst
- Select the appropriate specifications of the silicone tube
In the selection of silicone tube, should be based on the use of environment and conditions, choose the appropriate specifications of the silicone tube. Silicone tube specifications mainly include the inner diameter, outer diameter, wall thickness and working pressure.
Inner diameter: the inner diameter of the silicone tube should match the inner diameter of the connection.
Outer diameter: The outer diameter of the silicone tube should match the installation space.
Wall thickness: the wall thickness of the silicone tube should be able to withstand sufficient working pressure.
Working pressure: the working pressure of the silicone tube should be higher than the maximum pressure in the use environment. - Avoid using silicone hoses in high temperature environment
The temperature range of silicone hose is -40℃~200℃. If the temperature is too high, it will cause the silicone tube to age and become brittle, thus bursting. Therefore, the use of silicone tubing in high temperature environments should be avoided.
If you need to use silicone tubes in high temperature environments, you should choose high temperature resistant silicone tube.
When using silicone hose in a high temperature environment, the condition of the silicone hose should be checked regularly and the aging silicone hose should be replaced in time. - Avoid contact with chemical substances
Certain chemicals can corrode the silicone tube, causing it to become brittle and thus burst. Therefore, silicone hoses should be avoided contact with chemical substances.
If you need to use silicone hose in a chemical environment, you should choose chemical-resistant silicone hose.
When using silicone tubing in a chemical environment, protective measures should be taken to avoid direct contact of silicone tubing with chemical substances. - Use silicone tubing with care
When using silicone hose, it should be handled carefully to avoid mechanical damage.
When handling or installing silicone tubing, it should be placed carefully and gently to avoid impact or extrusion.
Avoid excessive bending or twisting when using silicone hoses. - Regular inspection of silicone hose
The silicone hose will gradually age during use. Aging will cause the silicone tube to become brittle and thus burst. Therefore, the silicone tube should be inspected regularly and the aging silicone tube should be replaced in time. For aging silicone tubes, it should be replaced in time.
In short, to be able to select a good silicone tube, you can identify by some methods, generally speaking, the better silicone tube, there is a gentle odor, mainly because of the residual sulfurizing agent, if placed in the air for a few days, the smell will be eliminated, while the poorer silicone tubes, the smell of stinky, the nose smells very pungent.
