What are the significant defects of vacuum bellows that cannot be ignored?

Vacuum bellows, as an important pipeline component, has a wide range of applications in multiple fields. However, there are also some shortcomings that cannot be ignored during use, mainly including the following aspects:
Uneven inner wall: This is usually caused by low vacuum degree, high water jacket temperature, or thin inner layer. The unevenness of the inner wall can affect the transmission efficiency of the fluid and may even cause problems such as fluid leakage.
Poor expansion: Poor expansion includes the inner layer being blown open, the inner and outer layers of the expansion not being properly attached, and incomplete expansion. These problems are often caused by excessive inner gas pressure, poor toughness of raw materials, thin inner layer, delayed or premature start of expansion and deflation. Poor expansion can seriously affect the sealing and performance of vacuum bellows.
Production process defects: such as scratches on the inner layer and small holes on the outer wall. These defects may be caused by high material temperature, impurities inside the material, mold scratches, and other reasons. These defects not only affect the appearance quality of vacuum corrugated pipes, but may also affect their service life and performance.
Material performance issue: The material performance of vacuum corrugated pipes directly affects their effectiveness in use. If the material performance is unstable or does not meet the requirements, it may cause various problems during the use of vacuum corrugated pipes, such as high brittleness and insufficient ring stiffness.
Installation and maintenance issues: The installation and maintenance of vacuum corrugated pipes are also important factors affecting their performance. If installed improperly or not maintained in a timely manner, it may lead to problems such as leakage and vibration in the pipeline system, which in turn affects the normal operation of the entire system.
In summary, it is necessary to pay attention to the above defects during the use of vacuum corrugated pipes, and take corresponding measures for prevention and treatment to ensure their stable performance and long service life.
