        What are the causes of leaks in grooved pipe seals?

        source: admin Release date: 2019-11-26

        The problem that the grooved pipe sealing ring is worried about when using is leakage. So what is the cause of the leakage of the key sealing ring of the groove? Let's follow the manufacturer of grooved pipe seals to find out.

            1. One of the reasons for the grooved pipe sealing ring along the radial direction is that the grooved pipe sealing ring will deteriorate and deteriorate, and the elasticity will be reduced after failure. Therefore, O-rings are usually replaced during equipment maintenance.

            2. The size is too poor, especially when the depth is too large, the compression deformation of the O-ring is insufficient after installation, which affects the sealing ability. Generally, the amount of compression deformation after installing the O-ring should be between 18% and 22%. When the size is large, the relative compression deformation is small, and when the size is large, the relative compression deformation passes.

            3. The material cannot be used as a sealing medium, nor can it be used after corrosion.

            4. The nominal size is too different from the actual installation size. O-rings are formed to work with reduced cross-sectional dimensions after stretching, resulting in insufficient compression deformation and leakage.

            5. The accumulation of diaphragm and sealing surface will also affect the sealing effect of O-ring. Therefore, when using O-rings, pay attention to the above conditions to prevent leakage.

            6. During installation, there is no smooth chamfer or fillet at the entrance of the sealing surface, which will cause the O-ring to be scratched and cause leakage.
