Filter tube, also known as “filter pipe”. The most famous filter tube is “Johnson tube.” However, there are many filter tube types.
Material: plastic filter tube, ss filter tube, mild steel zinc plated filter tube, other metals filter tube.
From production process points are: punching, laser openings around the wire, and so on.
Filter pipe is generally considered to be the heart of the well pipe, drainage pipes susceptible to this type of chemical, electrochemical, and the role of bacteria in groundwater and corrosion and clogging, reduce the feed water efficiency and reduce the life of the well. Especially when groundwater corrosive strong, severe damage will make a lot of gravel into the well, resulting slurry pump wells and burned, so that wells scrapped. To solve this problem, people developed ss filter tube, fiberglass filter tube, or asbestos cement pipe wrapping filter, filter grind paste, etc..
SS filter tube Purpose: The purpose for the majority of oil wells, gas wells, water wells, but also for filters, food processing, manufacturing, chemicals and so on.
