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.
Various kinds of Johson screen pipe
Radial Slot Execution Special
The Radial Slot Execution special design works with filtration from inside to outside. The slot profile is welded with the broadest profile dimension farthest to the inside support bar. The inside working surface on the other hand is interrupted by the path of support bars that hold it together.
Radial Slot Execution Standard
The Radial Slot Execution standard design works in a reverse flow format where the slot tube’s filtration happens to be from outside to inside area. The surface profile is welded to the broadest profile dimension outermost to the inside support bars. The outer working surface is smooth.
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.
Advantages of Jonhson screen pipe
1. Bigger filter area preventing buildups of impurities;
2. Easy maintenance/back flushing;
3. Low operational cost;
4. Minimum gap between profiles is about 20 micron (0.020mm);
5. Stop impurities/particles with its v-shaped construction.
