AM Monday – Expansion Joints & Duct Transitions – The Hidden Failure Path

March 23, 2026

Expansion joints absorb thermal movement between oxidizers and ducting. They protect structural integrity while maintaining system sealing. Because they are flexible and external, failures are often overlooked.

Thermal cycling, chemical exposure, and mechanical fatigue gradually weaken joint materials. Small leaks can persist undetected for long periods.
Challenges:

Leaking joints allow uncontrolled air ingress, disrupt pressure balance, reduce efficiency, accelerate corrosion, and create safety hazards. Damage often spreads downstream before the root cause is identified.

Solutions by Ship & Shore Environmental:

Ship & Shore Environmental (SSE) inspects expansion joints for wear, leakage, and installation integrity. SSE performs leak testing, recommends replacement schedules, and ensures proper joint selection for operating conditions.

Results:

Maintained expansion joints preserve thermal efficiency, protect personnel, extend duct life, and prevent costly structural damage. SSE’s proactive approach eliminates a common hidden failure path.
