KB DUCTING

This solicitation seeks a complete modular stainless‑steel ductwork system for industrial dust, mist, and fume collection. The requirement covers a wide range of duct sizes (12‑28 inches), flanged and clamp‑together connections, adjustable sleeves, clamps, saddle hangers, elbows, reducers, and branch fittings. All components must be fabricated from commercial‑grade stainless steel (Grade 304 or 316), feature rolled‑lip or flanged ends, and meet strict weld‑quality and leak‑resistance criteria. The buyer may accept equivalent items that meet or exceed the specified performance and dimensional standards. • 28‑inch flanged duct sections (20 ft total) and associated 45° double‑lateral branch. • 24‑, 18‑, 16‑, 14‑, and 12‑inch duct sections, clamps, sleeves, hangers, elbows, reducers, and Y‑branches. • Heavy‑duty stainless‑steel clamps with Buna‑N gaskets; Neoprene flange gaskets where required. • Adjustable telescoping sleeves (11 in length) for length adjustments without field welding. • Hat‑style saddle hangers pre‑punched for 3/8‑ or 1/2‑in. threaded rods. • All items must be shipped palletized/crated to preserve roundness and protect flanges.
