welding Galvanized stainless steel bridge slotted well screen
Stainless Steel Bridge Slot Water Filter Screen slots of this kind of screen are punched precisely in a flat sheet which then is rolled into a pipe. The sand and gravel can't easily block the slot because of the special bridge style design, and Bridge Slot Screens has great mechanical strength and water entering capacity. Meanwhile, Bridge Slot Screens use steel punching technology and is rolled in many ways, so they are light, cheap and easily operating.
Advantage
1, the special structure of the bridge-shaped orifice makes the gravel difficult to block the orifice, a higher ability to cross the water. According to the test, the porosity of the traditional drainage pipe filled gravel should be reduced by 40%, while the bridge drainage pipe only decreased by 10%
2, the special structure of the bridge-shaped drain pipe to play a role in enhancing the mechanical strength of the filter, with high mechanical strength
3, low cost, due to the abolition of the traditional process of manufacturing the filter pipe and wire winding process, the cost down 20%. And save drilling and wrapping time
4, according to the needs of users coated with different anti-corrosion layer, can improve the service life of wells
5, use a variety of connections, under the tube easy to operate
6, can change the gap of the bridge hole for different sandstone geology
7, a unique spiral structure design greatly increased the tensile strength and crush strength
