Bridge slotted screen for water wells

Bridge slotted screen is normally used in water wells for sand controlling. It is manufactured from precision punched quality metal sheet including ST37-2 or stainless steel 304/316L. The slots are punched in a flat sheet and at the same time the sheet is rolled into a tube and welded. Slots are arranged in staggered arrangement to reduce negative effect on the screen’s strength.

Bridge sand screen is a combination of superior weld strength and accurate slots. The slot openings are not completely punched out to increase mechanical strength. The slot of bridge screen is like a gravel pack retainer allowing the odd of blocking is very low. The prerequisite of bridge screen is the right gravel pack design.
