How much do you know about the knowledge of PE double-wall corrugated pipe? If you want to use it better, you need to test the water pressure. The following is an introduction to the precautions for the water pressure test of the PE double-wall corrugated pipe. :
1. The water pressure test of the PE double-wall corrugated pipe should be conducted in a unified manner, with a clear division of labor, and designated personnel responsible for inspection of the back, buttress, interface, exhaust valve and other parts, and clearly specify the contact signal when a problem is found.
- The hydraulic pressure test should be gradually boosted, and each boost should be 0.2Mpa. After each boost, continue the boost when there is no problem after the voltage is stabilized.
3. Anti-freezing measures should be taken during the PEX Fittings Plasticwater pressure test in winter. The backfill of PE double-wall corrugated pipes can be appropriately increased, and the exposed joints can be tightly wrapped with multi-layer straw curtains. Wrap the temporary pipelines for water pressure test to keep them warm, and vent them in time when not using water.
4. During the water pressure test, no one should stand near the back, support, pipe end, etc., and the inspection should be carried out when the pressure is stopped.
