Sudbury International expansion joints meet strict design criteria for ducting

For the best custom expansion joints for ducting systems, manufacturers need to consider seven criteria.

Sudbury International Engineered Products Limitedis a respected supplier of ducting expansion joints. For these joints to operate in ducting systems with maximum lifespans and reliability, they must meet strict design criteria. Manufacturers can custom-design these products for optimal effectiveness in specific applications, but they need to consider the customer’s situation to do so.

To get the proper ducting伸缩缝from Sudbury International, it is wise to consider several points.

Service, medium, and more

Customers who approachSudbury Internationalto find custom expansion joints for ducting systems should keep the following criteria in mind:

• Service.服务类型的plant, and location in the facility are among the most important pieces of information to consider. This gives the distributor an idea of the demands put on the joints, unlike data on specification sheets. Other examples include type of fuel, peak or base load, number of start/stop cycles per year, and whether installation is indoor or outdoor.
• Medium.Knowing the medium (e.g. air or flue gas) is important for choosing materials and the design of baffle construction. Other important factors include chemical composition, medium condition, dust contents, flow velocity and volume, and whether the turbine is washed.
• Pressure.The system-operating pressure can affect the design of ducting expansion joints, especially regarding their flexible nature. Pulsation and flutter are key criteria to keep in mind.
• Temperature.Knowing the operating, design, and ambient temperatures helps the manufacturer calculate the temperature gradient during joint construction. Also helpful are the medium, dew-point, and max excursion temperatures.
• Movements.The required active length usually depends on the amount of movement. The material for the number of layers and types affects the relevant flexibility of the individual product.
• Duct geometry.Duct size, thickness, material, corner angles, and insulation must be considered before completing a quotation, as well as flange-connection size and material.
• Scope of supply.The manufacturer can supply some or all of these relevant requirements, such as belt and flange type, insulation pillow, flow liner, gaskets, backup fasteners, installation, supervision, mounting/attachment frame, and splicing.
