Expansion Joint with Guide Tube for Negative Pressure

Expansion Joint with Guide Tube for Negative Pressure has the following features and advantages:

1. Resistance to Negative Pressure and Vacuum:
It can truly withstand negative pressure and vacuum, ensuring the safe and stable operation of the pipeline system under negative pressure conditions.

2. Prevention of Collapse:
Effectively prevents the rubber joint from collapsing under negative pressure conditions, maintaining the normal flow of the pipeline.

3. Flexible Material Selection:
Depending on different media, whether it is for ordinary water pipelines or acid and alkali pipelines, we can produce negative pressure devices with matching materials according to your requirements.

4. No Impact on Other Performances:
It does not affect the damping, noise reduction, displacement, and other performances of the rubber joint itself, ensuring that other functions of the pipeline system are not affected.

5. Drawback: Flow Impact:
Since the inner diameter of the expansion joint with guide tube for negative pressure is usually smaller than the main pipeline’s inner diameter, it may affect the flow by about 10%.

The expansion joint with guide tube for negative pressure provides a reliable solution for the operation of pipeline systems under negative pressure, with its resistance to negative pressure and prevention of collapse. However, it is important to note its impact on flow rate.

Note: The material, diameter, length, pressure, and flange standard sizes of rubber expansion joints can all be customized according to your requirements. With over 30 years of professional experience in rubber product manufacturing, we can solve various pipeline connection issues for you.
