For farmers, these professional terms are a real headache, but when choosing PVC lay flat hose, they have to understand. PVC lay flat hose plays an important role in agriculture and fire protection. Therefore, the quality requirements of PVC lay flat hose are also very high. Here, I would like to introduce to you: straight blasting pressure, after the measurement of seepage, uniformly raise the pressure to the prescribed straight blasting pressure, maintain for 5 seconds, test PVC lay flat hose sample can not rupture. Pressure rise time is maintained at 30-60 seconds; Curved blasting pressure, after measuring water seepage and pressure relief, bend the test PVC lay flat hose sample into an arc with an inner radius of 700 mm, and ensure that a fold edge of the test PVC lay flat hose sample is on the outside of the arc, evenly raise the pressure to the prescribed curvature blasting pressure. The test PVC lay flat hose sample can not rupture, and the pressure rise time is ensured. Keep it in 30-60 seconds; after measuring the breaking pressure, the test PVC lay flat hose sample is folded in the middle to align and fix the two ends of the test PVC lay flat hose sample. The pressure of the test PVC lay flat hose uniformly rises to the prescribed breaking bursting pressure and keeps it for 5 seconds. The test sample shall not break down and the boosting time is 30-60 seconds.
