Flange fastener assemblies may have a variety of problems, including leakage, loosening, wear, etc. Here are some common problems and how to deal with them:

1. Leakage: This is the most common problem, which may be caused by the failure of the sealing gasket, the insufficient pre-tightening force of the bolt, or the scratch or depression on the surface of the flange. The solution is to replace the new sealing gasket, ensure that the bolt preload is sufficient, and check and repair the flange surface.

2. Loose: If the flange fastener is loose, it may lead to leakage or system failure. This can be caused by vibration, thermal expansion, or corrosion. The solution is to check and tighten the bolts regularly, use an anti-loosening device such as a spring washer or lock nut, and treat corroded areas with corrosion protection.

3. Wear and tear: After long-term use, flange fasteners may wear and affect their performance. This may be caused by improper material selection, unreasonable design or timely maintenance. The solution is to choose the right material and design, regular maintenance and replacement.

4. Thread damage: excessive tightening or improper disassembly may lead to thread damage. The solution is to follow the correct operating procedures during installation and disassembly to avoid excessive tightening.

5. Excessive pressure: If the pressure of the flange is too large, it may lead to the failure of the fastener. The solution is to correctly select and use flanges and fasteners according to the design requirements to avoid overload operation.

The above are only some basic exclusion methods, and specific solutions need to be analyzed and judged according to the actual situation. Flange fastener assembly common problem elimination
