Product Description

Bridge slotted water well screens, a type of well screen with vertical slots that are formed by protruding "bridges" that are pushed outward from the well casing.
The 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.

The sand and gravel cannot easily block the slot because of the special bridge design.It has great mechanical strength and water entering capacity. Meanwhile,

Stainless steel well screen pipes are used for oil and water exploiting.
