Deep well water filter pipe/johnson screen (manufacture)

Construction of perforated casing pipe based prepacked well screen tube:
Perforated base pipe provides support to the wedge wires which are directly wrapped onto the base pipe. Advanced welding technology welded the screen to the pipe with superior weld strength and accurate slot openings. Rib wires create a tighter grip between screen and perforated pipe to strengthen and achieve stronger screen.V-shaped wire creates keystone geometry and self-cleaning performances for lower possibility of clogging.External forces are directly transferred to base pipe. 
Many ribs are designed for collapse resistance.Wire wrapped screens produces ten times of open area as the size of slotted liners. This significantly improves well life and filtration capacity.

Perforated pipe or perforated casing is designed for creating direct link between the wellbore and the producing formation through punched holes in the casing and the cement sheath that surrounds it. It is usually used as a protect casing or supporting pipe of other well screens, such as pipe-based wire wrapped screen The size and distribution of perforated hoses pose a direct impact on well productivity.
