Usage Methods of PE Nylon Fish-shaped Expansion Sleeve
1. Installation Preparation
Before installation, carefully check the pipeline specifications to ensure the expansion sleeve size matches. Prepare specialized installation tools, including expanders and fixing clamps. Clean the pipeline connection area to remove burrs and impurities.
2. Installation Steps
Insert the expansion sleeve into the pipeline connection point. Use an expander to apply even pressure, allowing the expansion sleeve to fully expand. Adjust the expansion level to ensure a tight fit with the pipeline's inner wall. Use fixing clamps for temporary securing and remove them once the connection is stable.
3. Precautions
Control the expansion force to avoid material damage caused by over-expansion. Ensure the working environment temperature is between 5-40°C for optimal installation results. Conduct a pressure test after installation to ensure connection reliability.
