How to Choose the Right Pressure Rating for Your PE Composite Layflat Hose?

When selecting the pressure rating of PE composite layflat hose, first confirm the actual output pressure of the water pump. The rated working pressure of the hose shall be higher than the maximum outlet pressure of the pump. Pressure loss caused by pipe joints and elbows should also be taken into account to prevent burst and leakage from long‑term overpressure operation.

Secondly, match the pressure rating with your application scenarios. Low‑pressure hoses are suitable for farm irrigation and routine drainage. Higher‑pressure hoses are required for mine sewage discharge, high‑rise building drainage and long‑distance water conveyance. Anti‑aging performance shall also be considered for outdoor exposure applications.

Finally, reserve sufficient safety margin. It is recommended that the burst pressure be 3‑4 times the actual working pressure instead of selecting based on transient peak pressure. For harsh working conditions with frequent dragging and bending, upgrade to one higher pressure specification to extend hose service life.
