Precipitation filter pipe. The product has the following characteristics: 1, high porosity. This product is more than 25% porosity. High porosity can reduce water infiltration rate, reduce the flow resistance, improve the quantity of water and shorten the duration of precipitation. 2, the gap should not be blocked. Slit width within narrow outer structure will not be blocked by sand. 3, the tubular body to withstand pressure. No weld surface of the product, but higher than other pipe ability to withstand pressure. 4, good sand control. The product gap control is accurate, error is small, can effectively block the outer filter and sand into the well, reduce the loss of the pump device. 5, to facilitate construction. This product is compared to the bridge flower pipes, cement pipes, which are light weight, easy to go down, to reduce the risks and other factors of insecurity caused by the construction.
