Component Specifications

Definition
A duct connection collar is a precision-engineered component designed to connect two sections of ductwork in industrial ventilation and exhaust systems. It typically consists of a cylindrical or rectangular sleeve with flanges, gaskets, and fastening mechanisms to create a sealed, rigid joint that prevents air leakage, maintains pressure integrity, and allows for thermal expansion and vibration dampening in systems like hood capture inlets.
Working Principle
The collar works by mechanically clamping or bolting two duct ends together using flanges, with sealing gaskets compressed between surfaces to create an airtight barrier. It maintains alignment, transfers mechanical loads, and accommodates minor misalignments while ensuring smooth airflow with minimal turbulence or pressure drop.
Materials
Galvanized steel (common), stainless steel (for corrosive environments), aluminum (lightweight applications), with EPDM or silicone gaskets for sealing.
Technical Parameters
  • Flange Type Slip-on, weld-on, or angle ring
  • Leakage Class L1 (EN 1507)
  • Diameter Range 100-1000 mm
  • Pressure Rating Up to 2500 Pa
  • Temperature Range -20°C to 120°C
Standards
ISO 5801, DIN 24194, ASHRAE 120
