AYVAZ MKDF30 Metal Bellows Axial Expansion Joint DN40

Absorbs axial thermal expansion to protect pumps, valves and pipeline integrity.

AYVAZ MKDF30 Metal Bellows Expansion Joint controls thermal expansion in industrial piping systems, moreover it delivers dependable performance in medium-sized applications. In addition, its DN40 nominal diameter and 30 mm expansion capacity suit steam and hot water lines. A stainless steel body allows safe operation between -80°C and +427°C.

The unit absorbs expansion movements parallel to the pipe axis, therefore it shields pump and valve assemblies from overload and extends system service life. Its PN16 nominal pressure class balances internal system pressure, and rotating flanged connections make installation and replacement straightforward. The flange is St 37.2 carbon steel, painted.
