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

Once installed, the expansion joint takes up length change, lateral offset and angular deflection of the pipe run and damps structure-borne noise. The data sheet gives a nominal size of DN 40. The stated figures are a face-to-face length of 125 mm and a flange outside diameter of 150 mm. Also stated are 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 EPDM 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

On pumps and compressors the DN 40 joint keeps the structure-borne noise of the machine out of the pipe run.
