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

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 300. This version is listed with a face-to-face length of 200 mm and a flange outside diameter of 445 mm. The stated material is NBR (high temperature). This version is supplied with 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 (high temperature) with a steel cord carrier, permitted up to max. +110 °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

On pumps and compressors the DN 300 joint keeps the structure-borne noise of the machine out of the pipe run.
