What type of Weld Pins to use on ductwork with Elastomeric Duct Liner?

When a shop is securing weld pins to Fiberglass Duct Liner, it’s typical that they use pins that have a shorter length than the thickness of the liner. On 1″ Fiberglass Duct Liner, for example, 3/4″ long weld pins are used. This compression resembles the quilted look of buttons on a leather chair. By spotting

Flexible Duct Connectors control Vibration in Ductwork

In HVAC Ductwork, Pressure and Velocity are two standards around which Engineers design duct plans. Building duct to a Higher Pressure class however doesn’t improve the system’s performance in handling vibrations that accompany changes in Velocity. In Duct Fabrication, the familiar criteria on the checklist towards reaching an excellent Pressure Class performance include Duct Gauge

FPP5 Bulk Feed Conversion Platform for Pinspotters

Rectangular Ductwork is typically insulated internally with Duct Liner rather than externally with Duct Wrap because of the acoustical benefits. Most duct shops will have two pinspotters for use in securing the Duct Liner to the Metal ductwork: a free standing “FG” model with a 5 ft throat and a smaller “MF” model with a 12
