Storage and installation precautions of rubber oil hose
Industrial oil hose is the necessary material in oil industry. It is used to deliver oil between equipment and tank. However, all the rubber hose has a certain service life. Then how often shall we replace an oil hose? In fact, there are many signs that tell you to replace a new hose.
Appearance
Severe aging and cracking
When a large number of dense and deep cracks appear on the surface of the rubber oil pipe, it indicates that the rubber has aged seriously. Its sealing performance and strength have been greatly reduced. If it continues to be used, it may leak or break at any time. Therefore, you need to replace it.
Obvious bubbling and bulging
If there are obvious bubbles or bulges on the surface of the oil pipe, it means that the internal structure of the oil pipe has been damaged. . At this time, the oil pipe has serious safety hazards and should be replaced in time.
Damage and tearing
The surface of the oil pipe has scratches and cuts, and the depth reaches a certain degree. Or there are obvious tears, which destroys the integrity of the oil pipe. The oil may leak from the damaged area. At this time, the oil pipe must be replaced to ensure safety.
Severe discoloration
The color of the rubber oil pipe has become darker or lighter obviously and over a large area, which is very different from the normal color. It is usually affected by factors such as high temperature and chemical erosion. Its performance may have changed, and you should replace it.
Performance
Oil leakage
Oil leakage is found on the surface and connection parts of the oil pipe. Even if the leakage is small, it means that the sealing performance of the oil pipe has problems. Over time, the leakage will gradually worsen and affect the normal operation of the equipment.
Hard or softened oil pipe
Normal rubber oil pipes have a certain degree of flexibility and elasticity. If the oil pipe becomes abnormally stiff, it is easy to crack when bent. Or it becomes too soft and loses elasticity. Failure to maintain normal shape and strength indicates that its performance is not up to standard.
Unstable pressure
The pressure in the oil pipe fluctuates abnormally. The pressure drops suddenly or cannot remain stable. It may be that there is damage, leakage or deterioration of elasticity inside the oil pipe. At this time, the hose cannot withstand normal working pressure and should be replaced.
