The construction of special filter dewatering well pipe wire wrapped screen
Geothermal wells filter pipe geothermal pump well controlled sand filter pipe wrapping filter wells special flower tube, with a center tube screen
(wire tube, wire, tube ladder filter pipe, water pipe, air conditioning wells geothermal wells filter filter pipe, spray sand filter pipe, pipe, drill sand around the wire pipe, recharge well with filter pipe)
Set screen casing 139.7mm 144 screen, 177.8mm sleeve 182mm
The wedge shaped filter pipe is welded by a wedge type winding and a wedge shaped reinforcing bar (or a circular rib bar) at each crossing point.
Product features:
1, wedge filter pipe structure is strong, high porosity, accurate size. Especially suitable for fine sand and silt formation.
2. The opening area of the wedge shaped filter pipe is large, the proportion of the filter area is high, the maximum can reach 60%.
3, wedge type structure design can effectively prevent the screen clogging and easy backwashing.
4, the larger filter area makes the groundwater more easily into the well, so as to get plenty of water, the water level drop down, thereby reducing energy consumption.
5, large filtering area can be decreased when the pressure of water inflow, can avoid the sand into the well in the larger pressure tube, thereby reducing friction, sand and equipment to reduce wear and prolong the service life of equipment.
6, in the same length, diameter and gap condition, wedge wire filter pipe flow is 3 times the bridge filter pipe, water pipe is 9 times.
7, customers can choose any screen size gap between 0.1mm-6mm, to meet the different construction conditions.
Filter material: stainless steel, galvanized steel, carbon steel or other material of customer requirements.
Application environment: suitable for vertical or inclined wells and directional wells etc. most wells tube gravel sand work.
Connection: connecting groove or threaded connection.
