Introductions of gravel pack screen
Gravel pre-packed wedge wire screens consists of a standard screen with a layer of gravel(with resin coating or without coating) placed around it supported by a second screen .The thickness of the gravel layer can be varied to meet special needs.
Characteristics of gravel pack screen
1. High strength performance.
Screens with high open area are more suitable for the construction of high-quality water wells, oil wells and gas wells.
2. Low cost in operation.
3. Reduce the abrasion of the pump
Under the same condition, high open area can make the speed of groundwater’s entering into the screen much slower than any other filtration apparatus.
4. Long usage time.
Comparatively, groundwater’s entering into screen with higher open area is much easier than the entering into lower open area screen.
