Introduction:
Water filter pipes are pipes with punched holes on the wall. These pipes are widely used in all types of underground water process projects.
The holes on the pipe walls are of different profiles. The most common and advanced profile is the bridge type hole.
The filter pipes are produced in different ways. In old conventional way, the holes are milled or drilled on the wall after pipes are produced. In this way, not only the hole quality and production efficiency is very low, but also the profiles of holes are limited to round hole or long rectangular holes. The most advantage bridge holes are not possible.
