Rectangular Expansion Joints

Rectangular Expansion Joints are manufactured to individual sizes and functional requirements by combining standard corrugated elements and corner configurations with self-developed fabricating methods to be used as duct expansion joints. Rectangular Expansion Joints are provided either with weldable duct ends or with fabricated angle flanges. These duct expansion joints are normally used in large size ducting with relatively low internal pressure. The most commonly used materials for the bellows elements are austenitic stainless steels of different grades and carbon steel for the end connections. Material selection is mainly determined by the service conditions. We design and manufacture Rectangular Expansion Joints confirming to the internally recognized E.J.M.A. (Expansion Joints Manufacturers Association). Rectangular Duct Expansion joints are normally supplied with any of the three corner configurations as illustrated below namely :

• Bevel Corner
• Mitre Corner
• Rounded Corner

Rectangular Expansion Joints are supplied with matching flanges that can be welded to the other side of the duct and can be bolted with the flanges of the rectangular expansion joints easily. We manufacture 500 mm to any large size and as per customer drawings. Highlights :

• Sturdy construction
• Resistance against corrosion
• Smooth finish
• Accurate dimensions
