### Description

<p><strong>Salient Characteristics Specification: Modular Stainless Steel Ductwork System</strong></p>
<p>Document Control Number: SC-DUCT-SS-001</p>
<p>Subject: Modular Clamp Together and Flanged Stainless Steel Ducting and Components</p>
<p>Basis of Design: KB Duct (CECO Environmental) or Approved Equal</p>

<div>
  <p><strong>1. Scope and Purpose</strong></p>
  <p>This document lists the basic physical and operational features needed for industrial grade stainless steel ducting. These parts make up a complete dust, mist, and fume collection system. The modular design allows fast setup, easy layout changes, leak resistance, and corrosion protection. When specific part numbers from KB Duct are referenced, they show the required design standard, build quality, dimensions, and performance. Any substitute items offered must match or exceed these key requirements.</p>
</div>

<div>
  <p><strong>2. General System Requirements</strong></p>
  <ul>
    <li><strong>Material:</strong> All duct pipes, branch pieces, elbows, reducers, sleeves, and hangers must be made from commercial grade Stainless Steel (minimum Grade 304 with mill finish or 2B finish; Grade 316 is also acceptable).</li>
    <li><strong>Connection Types:</strong>
      <ul>
        <li><strong>Clamp Together (Rolled Edge):</strong> Standard straight pipes, branch fittings, reducers, and elbows must have a rolled lip edge on each end. This allows quick connection clamps to join parts together without needing field welding, rivets, or sheet metal screws.</li>
        <li><strong>Flanged Ends:</strong> Select large diameter parts (28 inch duct, branch fittings, and adapter ends) must have factory welded angle or flat flanges with standard bolt holes.</li>
      </ul>
    </li>
    <li><strong>Pipe Seams:</strong> Straight pipe lengths and fabricated bodies must have smooth, solid, airtight welded seams to stop leaks and keep dust from building up inside.</li>
    <li><strong>Gasket Materials:</strong> Clamps must include chemical and oil resistant Buna-N (Nitrile) seals rated for standard industrial air temperatures. Flanged 28 inch joints must include Neoprene full face or ring gaskets with pre-punched bolt holes matching the flanges.</li>
    <li><strong>Adjustability:</strong> The system must allow quick length adjustments in the field using sliding sleeves and clamping adapters without cutting or damaging permanent pipe sections.</li>
  </ul>
</div>

</div>

<div>
  <p><strong>4. Component Details and Specifications</strong></p>
  <h4>4.1 Straight Pipe Runs</h4>
  <p><strong>Construction:</strong> Rolled cylindrical stainless steel pipe made from 20 gauge (for sizes 12 inch through 18 inch) or 18 gauge (for sizes 24 inch through 28 inch) Grade 304 stainless steel.</p>
  <p><strong>Lip Edge:</strong> Uniform rolled lip turned outward at 90 degrees around the rim, providing the lip that clamps grip.</p>
  <p><strong>Roundness:</strong> Pipe must be round and within 1/16 inch tolerance so clamps seat easily.</p>

  <h4>4.2 Quick Connect Clamps</h4>
  <p><strong>Design:</strong> Hinged stainless steel circular clamp with an inner groove shaped to wrap over mating rolled lips and compress the gasket.</p>
  <p><strong>Latch:</strong> Heavy toggle latch with a safety bridge or locking pin to prevent accidental release from machine vibration.</p>
  <p><strong>Gasket:</strong> Durable Buna-N rubber seated inside the clamp groove to prevent leaks of air, dust, and oil mist.</p>

  <h4>4.3 Lateral Branches, Y Fittings, and Reducers</h4>
  <p><strong>Branches:</strong> All branch taps must turn out at a 45 degree angle relative to the main trunk line for smooth airflow without clogging.</p>
  <p><strong>Reducers:</strong> Must use a gradual taper to keep air speed steady without turbulent eddies.</p>
  <p><strong>Weld Quality:</strong> All fittings must be welded continuously. Spot welding or sealant tape is not acceptable.</p>

  <h4>4.4 Sliding Sleeves</h4>
  <p><strong>Purpose:</strong> A pipe section engineered to slide over standard pipe to cover short spans without cutting or rolling lips in the field.</p>
  <p><strong>Sealing:</strong> Seals against the base pipe with a rubber seal or secondary ring clamp and ends in a standard rolled lip.</p>

  <h4>4.5 Saddle Hangers</h4>
  <p><strong>Design:</strong> Hat style bracket contoured to support the lower half of the duct.</p>
  <p><strong>Hanging:</strong> Carries pipe weight securely without denting the thin duct wall. Pre-punched for 3/8 inch or 1/2 inch threaded hanging rods.</p>
</div>

<div>
  <p><strong>5. Quality Standards and Equal Submissions</strong></p>
  <ul>
    <li><strong>Compatibility:</strong> All components must fit together smoothly. Any alternative brand submitted must connect directly to standard industrial clamp-together duct lines without adapters.</li>
    <li><strong>Finish:</strong> Clean, uniform finish free of slag, sharp edges, burrs, or zinc contamination.</li>
    <li><strong>Shipping:</strong> Items must be palletized, crated, or wrapped to keep pipe round during shipping. Flanges must have covers over the bolt faces.</li>
  </ul>
