Why rubber flexible joints crack at high temperature

[source: unknown] [date: 2020-09-16 15:58] [heat: ]
Why rubber flexible joints crack at high temperature
1. The high temperature rubber flexible joint used is inconsistent with the pipeline medium, and the pipeline medium temperature or corrosion is too strong.
2. The ball of high temperature resistant rubber flexible joint has a low rubber content, the application temperature reached by itself can reduce raw materials in the manufacturing process, reduce the high temperature content of rubber material itself, and mislead the supplier.
3. If the pressure is too high, the pipe pressure is not proportional to the ball pressure.
4. There is a problem with the installation method of flange butt joint, and the ball formed by pipe dislocation is seriously distorted. However, the most likely reason is that the pipeline medium and pressure problems will cause the ball burst, or the ball pressure resistance of the manufacturer is not high. Therefore, it is better to choose a good rubber flexible joint, which can be achieved at high temperature and high pressure.
working pressure:
1. The working pressure is 1MPa; it is the nominal pressure of the fluid inside the pipe and rubber flexible joint, 10kg.
2. The working pressure is 1.6Mpa; the nominal pressure of compressive strength at basic ambient temperature is 16KG.
3. The working pressure is greater than 2MPa and less than or equal to 3Mpa; it is generally used for air, compressed air and other high-pressure chemical pipelines.
