If a threaded joint is leaking while in service, which of the following actions is not recommended?

• A. Tighten the connection while in service
• B. Inspect the joint thoroughly
• C. Replace the gasket
• D. Shut down the system

Answer: (A)

Tightening a leaking threaded joint while it is in service is not recommended due to the potential risks involved. When a joint is under pressure, making adjustments can lead to several safety issues. The application of additional force may exacerbate the leak or even cause thread damage, resulting in a more significant failure. Additionally, the dynamic nature of the pressurized system can lead to unexpected consequences, such as sudden release of pressure, which poses hazards to personnel and equipment. In contrast, conducting a thorough inspection of the joint is crucial for identifying the root cause of the leak. This step can help determine whether the issue stems from wear, improper installation, or material failure. Replacing the gasket and shutting down the system are also important actions to take as these steps ensure that the joint is safe to operate and prevents further leakage or damage. Proper maintenance practices dictate that resolving leaks should be approached with caution to maintain system integrity and safety.
