Elastomer expansion joint, flange connection DN40-PN16 (DIN), bellows in butyl (CIIR)

The expansion joint takes up length change, lateral offset and angular deflection of the pipe run and damps structure-borne noise. In addition the sheet lists a working pressure of -1 to 16 bar. The stated figure is a nominal size of DN 40. The version is listed with the DN40-PN16 (DIN) flange connection.

Benefits

• Nominal size DN 40 on flange connection DN40-PN16 (DIN) at a working pressure of -1 to 16 bar.
• Axially the bellows takes 35 mm of compression and 10 mm of extension.
• Lateral offset up to 15 mm and angular deflection up to 25 degrees.
• Bellows in butyl (CIIR) with a synthetic fabric carrier, permitted up to max. +90 °C.
• Face-to-face length 125 mm at 16 mm flange thickness and 150 mm flange outside diameter.
• Steel flanges that turn on both sides make it easier to line up the hole patterns during installation.

Applications

In heating and cooling circuits the bellows in butyl (CIIR) takes up the length change of 35 mm.
