BLACOH “Do SENTRY units have ASME coding on the pulsation dampeners?
26. BLACOH No. ASME (American Society of Mechanical Engineers) standards do not apply until the internal diameter of the dampener exceeds 6 inches. Blacoh models up to 370 cubic inch sizes are under this dimension. All Blacoh dampeners have a burst pressure three or more times higher than the maximum operating pressure specified. For specific ASME information on other sizes, please contact Blacoh.
