Product Details

Perforated slotted steel pipe
  The perforated steel pipe is formed by forming a certain geometric shape and a certain regular arrangement of water inlet holes on the well pipe. This pipe can only be used directly in aquifers above coarse sand. Due to the different geometric shapes of the water inlet holes, they can be roughly divided into two types.
  Round-hole water perforated is an ancient and simple type in history. The perforations can be made in different ways depending on the pipe. Generally, metal pipes and asbestos-cement pipes are usually drilled or punched. For concrete pipes, round holes can only be reserved during pouring. The size of its perforations is mainly determined by the grain size of the aquifer. The arrangement of the water inlet perforations on the pipe wall usually adopts the staggered plum shape. The mutual positions of the water inlet holes can also be divided into two types: equal mapping triangles and equilateral triangles. In this way, after initially selecting the horizontal and vertical hole spacing of the inlet and outlet holes, it should also be adjusted according to the required opening ratio of different pipes, so that it can be processed when the hole spacing is basically an integer.
