Dampers(type- louvers) are essentially an assembly of plates designed to control theventilation in duct work systems by keeping debris from traveling in them. We have fabricated Louver type dampers (butterfly,guillotine, radial vane, and diverter) in the shop for past projects.
Sweco Fab, Inc. designed and manufactured two 5,000 lb. air intake stacks and two 300 lb. dampers for an oil refinery in Baytown, Texas. The air intake stack is designed to keep debris from traveling to the duct. It was manufactured from A-36 carbon steel and measures at 11’x 5’x 8.’ The damper is designed to control ventilation in the ducts. This damper is manufactured from galvanized carbon steel and measures at 73.5″ I.S. x 20.5″ I.S. x 7.5″ wide.

The picture above shows a flue gas duct damper fabricated using Inconel for certain components by the Sweco Fab division of Piping Technology & Products, Inc. Two of these dampers were shipped to Trinidad for installation above the furnaces of an ammonia plant. They have a special refractory lining to withstand the high temperatures of the flue gases. The picture at the left show the linkage of the damper to the motor-driven control system. Each unit weighs approximately 2300 lb. and the openings are approximately 12 feet by 6 feet.

This Webinar will focus on the different types of variable spring supports and big ton variable spring supports. Learn about the special features available, in addition to the design of a variable support. View how the different coil configurations produce a unique response to an applied load and see how a spring assembly is loaded. Discover the basic steps in selecting a hanger design and the step-by-step process used to size a spring for your application. Learn about the different attachments, testing, and installation and maintenance procedures. View examples of failed supports provided by our Field Service Division and learn why they failed and how to prevent it. Gain knowledge of the valuable tips used when deciding to replace or re-calibrate a variable spring support, as well as adjustments, shutdown, and isolation procedures.
