V & W-Shaped Bellow Rectangular Metal Expansion Joints with Camera Corner
V- and W-shaped bellow rectangular metal expansion joints with camera corners from Triad Bellows combine the superior flexibility of corrugated rectangular designs with the strength and stability of reinforced “camera” corners. Engineered to EJMA (10th Edition) standards and available in stainless steel (T-316L, T-321) or high-performance alloys (Inconel®, Hastelloy®, Monel®), these assemblies accommodate axial compression, lateral offset, and angular movement in rectangular duct and piping systems while minimizing stress at the corners. The V- and W-shaped convolutions provide exceptional pressure resistance and fatigue life—ideal for HVAC, petrochemical, power generation, marine, and industrial exhaust applications—while the camera-corner construction ensures uniform load distribution, prevents corner fatigue, and simplifies installation in tight or non-standard rectangular transitions. Triad’s U.S.-based fabrication ensures precision weld integrity, quick turnaround, and full customization to suit temperature ranges from –320 °F to 1,200 °F and pressures.
