Low carbon galvanized Johnson screen tube
Product Description
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 r ed, 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 fro in.m 1.5 in. / 38 mm to 18 in. / 457 mm.
