SS Pipe Based Well Screens which is also called sand control well screens, which is used in the oil well, gas well and water wells.
The base pipes screen jackets is constitute of API standard base pipes and the Johnson type well screens as the jackets wrapped outside of the base pipes.
Henan Tianzhiwo Machinery Co., Ltd Offers high quality Johnson Screen pipe,water well screen,wedge wire water well screen,
V wire water well screen,continuous wedge wire screen ,stainless steel water well screen,water filter and other related products.
Pipe based screen combines the hydraulic efficiency of a continuous slot screen with the strength of a pipe.
This pipe strength allows smaller wrap wires to be used, yielding greater open area. Longitudinal support rods direct inflow to the nearest pipe perforation.
Screen and pipe are welded together to make a rugged, reliable unit for deep vertical wells and long, horizontal remediation of supply wells.
Fittings are available to meet most well design and installation requirements.
The pipe based screen is recommended when high collapse resistance is required and when the screens’ length generates a high longitudinal constraint.
The pipe strength allows smaller wrap wires to be used, yielding greater open area.
Base pipes can be manufactured using stainless steel grades or API 5CT carbon steel casing. Johnson Screens uses prime pipe, thoroughly cleaned and de-burred after perforating.
Diameters for pipe based screens range from in. 1.5 in. / 38 mm to 18 in. / 457 mm.
