Elastomer expansion joint, flange connection DN250-PN10 (DIN/EN), bellows in butyl (CIIR)

As a expansion joint the article 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 250. This version is listed with a face-to-face length of 175 mm and a flange outside diameter of 395 mm. Material butyl (CIIR) is listed for this version. Also stated are the DN250-PN10 (DIN/EN) flange connection.

Benefits

• Nominal size DN 250 on flange connection DN250-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 7 degrees.
• Bellows in butyl (CIIR) with a synthetic fabric carrier, permitted up to max. +90 °C.
• Face-to-face length 175 mm at 25 mm flange thickness and 395 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 250 joint keeps the structure-borne noise of the machine out of the pipe run.
