Expansion Joints

Metal

Metal expansion joints are designed to overcome the same challenges as other materials while adding more structural integrity.  Metal expansion joints feature convolutions or bellows that provide the flexibility required to accomodate movements. Multi-ply bellows maximize cycle life under stringent conditions. Non-destructive testing available includes: pressure testing, liquid penetrant testing, fluorescent penetrant testing and radiography.
