- Installation instructions
2. When handling materials, throwing, dropping, rolling, and dragging are strictly prohibited to avoid damaging the pipeline Check both ends of the connecting pipeline If there is any damage, please cut off the damaged part.
3. Hot melt connection of hdpe pipe and fittings The welding temperature should be set at 260 ± 10 If there is any discoloration, decomposition, combustion, smoke or other adverse effects, please replace the welding machine.
4. Although threaded fittings are connected to other parts, they must not be tightened too tightly to avoid damaging the threaded fittings.
5. Please strictly follow the arrangement and business standards of double wall corrugated HDPE pipe to ensure quality
After installation is completed, a water pressure test must be carried out to confirm that there are no leaks, and then the pipe passage can be closed or filled The test pressure should be 1.5 times the design pressure The recommended test pressure is 10kg/cm2 (megapascals) -15 kg/cm2 (pressure 1.5MPa).
7. Although transitional connections with water heaters, ppr pipe,metal pipes or pvc pipe connections are acceptable, and their length should not be less than 300mm.
8. Outdoor pipelines should be considered to have insulation, sun protection, and anti freezing measures.
9. In winter, when the temperature approaches 5, accidental damage to pipes and fittings can be prevented during transportation and construction After completing the pressure test, discharge the water For long-term winter shutdown periods, there are no reliable insulation measures in place to prevent water discharge from the pipeline from cracking.
10. When carrying out waterproofing work, do not apply paint, asphalt, and other contaminated materials on the surface of the hdpe water pipe to avoid odor water.
