factory snad control pipe base water well screen strainer pipe

Pipe based screens are used in water wells in many parts of the world and are common in oil field work because of their strength and durability in non-vertical borehole applications. the assembly for this screen is made by perforating a base pipe and then mounting a continuous slot screen over it via one of three methods: 1) winding trapezoid-shaped wire directly onto a pipe(wrap-on pipe); 2) winding wire over longitudinal rods mounted around a pipe's circumference(pipe base); or 3) slipping a separate continuous slot well screen jacket over a pipe(screen jacket). winding wire over longitudinal rods is superior to the wrap-on pipe design because the rods hold the wire away from the pipe surface, blocking fewer of the base-pipe openings.
