  "summary": "Wedge wire screens in 316L and Duplex: flat panels, sieve bends, cylinders and baskets. Slots that widen downstream, so the screen clears itself.",
  "definition": "A wedge wire screen is a screening surface built from triangular profile wire welded at every crossing onto support rods that run underneath it. The flat top face of each wire forms one edge of a continuous slot, and because the profile tapers away below the surface, the slot widens downstream. A particle that passes the opening therefore keeps going instead of wedging in it. That geometry is why a wedge wire screen holds its capacity in service: the open area stays defined by the slot rather than by what has lodged in it, as long as the slot faces the flow and the surface is cleaned at the interval the duty demands.",

    {
      "title": "The slot, not the mesh number",
      "body": "Slot width is the rating, and it does not translate from a mesh count carried over from a woven screen. A slot retains in one direction only: a flake or a fibre that a square aperture stops can pass a slot of the same nominal width edge-on. Give us the cut point — the smallest particle you must hold and the largest you are content to let through — and a particle size distribution if one exists."
    },
    {
      "title": "Slot direction and screen form",
      "body": "Across the flow, each slot edge shears a layer off the stream and the surface keeps itself clear. Along the flow, resistance drops and drainage improves. Form follows the same logic — flat panel, curved bend, cylinder, basket or cone. Tell us how the medium arrives at the surface, not only what the old part looked like."
    },
    {
      "title": "Support rod pitch and load",
      "body": "The rods carry the panel. Too coarse a pitch and the surface deflects under a raking arm, a pressure differential or a foot; too fine and open area disappears into steel. Send the span, the mounting, the differential pressure and any mechanical contact with the surface — the pitch is a consequence of those numbers."
    },
    {
      "title": "Alloy, temperature and medium",
      "body": "304 covers benign duty; 316L covers most process water, food and beverage service. Chlorides, seawater, sour service and higher design temperatures move the choice to Duplex or a higher alloy. State the medium, its concentration and the design temperature — the alloy follows from those, not from preference."

  "faq": [
    {
      "q": "Why does a wedge wire screen blind less than perforated plate?",
      "a": "Because the opening is the narrowest point and nothing behind it is tighter. In a drilled hole the wall is parallel, so a particle the size of the hole jams and stays. In a wedge wire slot the profile falls away below the surface, so the same particle either does not enter or passes straight through. Blinding is not abolished — sticky, fibrous and greasy material still needs cleaning — but the mechanism that traps sized particles is gone."
    },
    {
      "q": "What slot width should I specify?",
      "a": "Start from the cut point: the smallest particle you must retain and the largest you are content to pass. Then look at shape. A slot retains in one direction only, so fibres and flakes can turn edge-on and go through an opening that would stop them in a square mesh. A sieve analysis is the fastest way to get this right; a photograph of the material is better than nothing."
    },
    {
      "q": "Should the slots run across the flow or along it?",
      "a": "Across the flow for sieve bends and anywhere the stream itself has to keep the surface clear — each slot edge shears a layer off the flow. Along the flow for drainage, dewatering and static retention, where low resistance and free run-off matter more. If a raking or brushing arm sweeps the surface, run the slots in the direction the arm travels, so the blade lies across the wire tops instead of along a slot it can drop into."
    },
    {
      "q": "Can you supply a curved sieve bend to replace one we already have?",
      "a": "Yes. Measure the chord and the arc, or the radius and the included angle, and add the slot width plus the way the panel is clamped top and bottom. If the existing screen is worn, its slot has usually opened up — take the target slot from the original drawing where you can, not from the panel coming out."
    },
    {
      "q": "What open area can I expect?",
      "a": "It follows from the geometry, not from a catalogue: open area = slot ÷ (slot + profile width). A 0.5 mm slot on a 3.0 mm profile gives about 14 %; a 3 mm slot on the same profile gives 50 %; a wide dewatering slot on a slim profile passes 80 %. A narrow slot on a wide profile therefore gives little open area — and carries more load for it. Open area, strength and slot width form one triangle: fix two and the third follows. Send the slot width and the load and you get the exact figure instead of a band."
    },
    {
      "q": "Which alloy should I specify?",
      "a": "304 for benign duty, 316L for most process water, food and beverage service. Chlorides, seawater, sour gas or higher design temperatures usually move the choice to Duplex or a higher alloy. Send the medium, its concentration and the design temperature and you get an alloy back with the reason attached."
    },
    {
      "q": "Do you supply cylinders and baskets, or only flat panels?",
      "a": "Both, plus conical sections. A cylinder can be built with the slot running around it or along it, and with the rods inside or outside depending on which face has to stay smooth. Say whether the flow runs in-to-out or out-to-in: that decides which way the slot has to widen, and getting it backwards turns a self-clearing screen into a filter cake holder."
    },
    {
      "q": "What data do you need for a quotation?",
      "a": "Slot width, panel dimensions or the arc for a sieve bend, the form (flat, curved, cylinder, basket, cone), flow direction, medium and design temperature, and how the screen is carried or clamped. A sketch of the frame helps; a drawing of the existing screen helps more. Availability and lead time are confirmed at quotation."
