BURGFLEX expansion joints are non-metallic flue duct expansion joints or flexible connectors which when properly designed, provide stress relief for piping & ducting systems by absorbing thermal growth and shock, isolating mechanical vibration and allowing for misalignment.

Flue duct expansion joints are custom engineered products designed to handle low pressure ( ±2000 mmwg ) applications with temperatures from -100 ℃ to more than 1200 ℃. The expansion joints are manufactured using innovative, non- metallic materials and designs
