In general, the PVC lay flat hose will be tested for various abilities before it leaves the factory. One of them is the pressure test for the PVC lay flat hose. And its pressure is divided into two kinds, one is the bending pressure, the other is the bending pressure, we need to understand that the two kinds of pressure testing methods are different.
The folding pressure of PVC lay flat hose is measured. After the water seepage is measured and the pressure is released, the PVC lay flat hose sample is folded in half, and the sample is folded together and fixed. Uniformly raise the pressure to the specified folding pressure, holding pressure for 5 seconds, the specimen shall not break, and the general boosting time is 30-60 seconds.
And the bending pressure of PVC lay flat hose, after measuring the amount of water seepage and relieving pressure, bends the sample into an arc with an inner radius of 700 mm. One flange of the PVC lay flat hose specimen should be placed outside the arc. When the pressure is uniformly raised to the prescribed bending pressure, the PVC lay flat hose specimen shall not be cracked. The boost time is 30-60 seconds.
