The compression nut tightens onto the compression pipe fitting, such as a compression elbow or coupling, through a threaded connection.
Here’s how the compression nut tightens onto the fitting:
- Threaded Connection: The compression nut is typically internally threaded to match the external threads on the compression fitting. jianzhi pipe fittings These threads allow the nut to be securely attached to the fitting.
- Fitting Preparation: Before tightening the compression nut onto the fitting, the pipe end is inserted into the compression fitting body. The compression ring or ferrule is also positioned over the pipe, ready to create a seal when compressed.
- Hand Tightening: Initially, the compression nut is hand-tightened onto the fitting to ensure that the threads engage properly. This helps align the nut with the fitting and prevents cross-threading.
- Compression: Once the compression nut is hand-tightened, additional torque is applied using a wrench or spanner to further tighten the nut onto the fitting. As the nut is tightened, it compresses the compression ring against the pipe, creating a secure and leak-tight seal.
- Compression Force: The torque applied to the compression nut generates a compressive force on the compression ring, causing it to deform and create a seal between the pipe and the fitting. The compression force is evenly distributed around the circumference of the pipe, ensuring a consistent seal.
- Seal Formation: As the compression nut is tightened, the compression ring forms a tight seal against the pipe surface. The material of the compression ring is soft and deformable, allowing it to conform to the shape of the pipe and fill any gaps or irregularities, further enhancing the seal.
- Controlled Tightening: Care must be taken to apply the correct amount of torque when tightening the compression nut onto the fitting. Over-tightening can damage the fitting or deform the compression ring, while under-tightening may result in a weak or inadequate seal.
- Verification: After the compression nut is tightened onto the fitting, the integrity of the connection should be verified by checking for leaks or visual signs of damage. Properly tightened compression fittings provide a reliable and leak-free connection in piping systems.
By following these steps, the compression nut tightens onto the compression pipe fitting, creating a secure and leak-tight seal between the pipe and the pipe fitting manufacturer . This ensures reliable performance and longevity in various plumbing, HVAC, and industrial applications.
