Materials and construction
Titanium diaphragm
Also known as Ti diaphragm, titanium driver diaphragm.
A titanium diaphragm is the premium driver element in many industrial sonic horns. Titanium's high strength-to-weight ratio, fatigue resistance and corrosion immunity to most flue-gas chemistries make it the longest-lived diaphragm material available.
Service life
A well-installed titanium diaphragm in typical industrial duty lasts 3–5 years of continuous service before replacement, with shorter life in particularly aggressive (high-chloride, high-temperature) applications and longer life in cooler or less corrosive duty. The stainless-steel alternative typically lasts 1.5–3 years in the same service.
Replacement is straightforward
A scheduled diaphragm replacement is a routine planned-maintenance task typically completed in under an hour per horn during a normal outage. Diaphragm degradation shows up as gradual SPL drift — instrumented horns flag the trend before output drops materially.
