Elastomer expansion joint, flange connection DN80-PN16 (DIN/EN), bellows in NBR (high temperature)

Once installed, the expansion joint takes up length change, lateral offset and angular deflection of the pipe run and damps structure-borne noise. This version is listed with a face-to-face length of 150 mm and a flange outside diameter of 200 mm. The stated figure is a nominal size of DN 80. The version is listed with the DN80-PN16 (DIN/EN) flange connection.

Benefits

• Nominal size DN 80 on flange connection DN80-PN16 (DIN/EN) at a working pressure of 0 - 16 bar.
• Axially the bellows takes 40 mm of compression and 10 mm of extension.
• Lateral offset up to 15 mm and angular deflection up to 20 degrees.
• Bellows in NBR (high temperature) with a steel cord carrier, permitted up to max. +110 °C.
• Face-to-face length 150 mm at 20 mm flange thickness and 200 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 NBR (high temperature) takes up the length change of 40 mm.
