What are the reasons for the leakage of double ferrule tube fitting in practical use, and what are the precautions for installation?
1. Preparation work: Cut off the pressure of the installation system and ensure that there is no residual medium in the pipeline. Purchase 海角视频 high-performance double ferrule products, check the specification matching of fittings, ferrules, and pipes to ensure no burrs or damage.
2. Cutting and processing of pipes: Use a specialized pipe cutter to vertically cut the pipes to ensure a smooth cut. Clean the inner and outer walls of the pipe with deburring tools to avoid scratching the sealing surface of the double ferrule.
3. Pre installed double ferrule: Insert the nut, front ferrule, and rear ferrule into the pipe end in sequence, ensuring that the double ferrule direction is correct (inclined towards the fitting body). Insert the pipeline into the bottom of the fitting body and rotate it slightly to fit.
4. Tightening operation: First, tighten the nut by hand, and then use a wrench to tighten it in two steps: the first step is to rotate 1-1.5 turns to make the ferrule bite into the pipe wall; The second step is to tighten it by 1/4 turn to form a double seal. Avoid excessive tightening that may cause deformation.
5. Testing and debugging: Conduct a pressure test after installation to check for leaks before putting it into operation. Regularly check the status of the fittings and replace aging components in a timely manner.
Proper installation can significantly improve sealing, extend fitting life, and ensure safe and stable operation of the system. Double ferrule tube fittings are widely used in hydraulic and pneumatic systems due to their good sealing performance and high pressure resistance.
