Elastomer expansion joint, flange connection DN300-PN10 (DIN/EN), bellows in NBR

In use, 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 200 mm and a flange outside diameter of 445 mm. The stated figure is a nominal size of DN 300. In addition the data give the DN300-PN10 (DIN/EN) flange connection.

Benefits

• Nominal size DN 300 on flange connection DN300-PN10 (DIN/EN) at a working pressure of 0 - 10 bar.
• Axially the bellows takes 45 mm of compression and 15 mm of extension.
• Lateral offset up to 15 mm and angular deflection up to 6 degrees.
• Bellows in NBR with a synthetic fabric carrier, permitted up to max. +90 °C.
• Face-to-face length 200 mm at 25 mm flange thickness and 445 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 takes up the length change of 45 mm.
