Slot and open area
The slot opening controls the geometric passage, while wire profile and support spacing affect open area and stiffness. Specify required slot width, screen diameter or panel span, flow direction and any backwash cycle.
Materials and assembly
SS304, SS316L or duplex grades are chosen against water chemistry, chlorides and mechanical loading. Define frames, flanges, welds and support members from the installed equipment drawing.
Information for quotation
Provide water chemistry, solids and flow information, a dimensioned drawing, slot requirement, support span, installation interface and cleaning method. For well screens, include screen length, end connections and any gravel-pack design constraints.
Design review
An intake panel, removable basket and well screen have different support and connection requirements even when the requested slot is similar. Compare slot width, profile-wire direction, open area, water chemistry, sediment characteristics and expected cleaning or backwash cycle. A well screen also needs the length, end connection and installation clearance defined by the bore design.
Inspection and acceptance
Provide the installed drawing with support span, flow direction and reverse-flow conditions. Inspect finished slot width at an agreed sampling plan and check frame or cylinder dimensions before dispatch. Hydraulic performance, clogging interval and corrosion life depend on site conditions and should be verified in the buyer's system.
Place each screen at its water-treatment interface
A nozzle cap retains bed media at the filter plate. A slotted cylinder forms a cylindrical intake or retaining boundary, while a flat or curved panel fits its own supporting opening. Select the component form from that location before choosing the slot.
For the nozzle joint, show cap height, threaded stem, plate thickness and gasket seat. For cylinders and panels, show the active face, end or edge attachment and the service/backwash arrows. Keep the collection passage open behind the screening surface.
