Description of the wedge wire screen pipe

 

Wedge Wire Screens are manufactured by wrapping a profile wire cylindrically around longitudinal placed support rods. All wires and rods are resistance welded at each point of contact. The numerous combinations of wire profiles, support rods, flow direction and wide range of slots (fixed or variable) allow AMACS to design screens according your exact technical specification. We manufacture wedge wire screens for a variety of industries including water well production, water treatment, food and beverage, oil and gas, pulp and paper, mineral and aggregate processing, refining and petrochemical.

Axial Slot Execution Special

The Axial Slot Execution Special Design has filtration from inside towards outside. The slots’ profiles are formed equivalent to the measurement of the slot tube and the support wire wraps the outside of the tubes forming profiles that are then connected together via pressure welding. The inside working surface of the tube is smooth.
