The role of the expansion joint is to protect the installations from vibrations and expansions that the pipework could undergo. The expansion joints allow lateral, axial and limited angular movements. The diversity of elastomers lets it respond to all kinds of applications: water, air, abrasive products, and certain acids. However, beware, they aren’t meant for correcting misalignments in the pipework.

APPLICATION

Hot water, cold water, water treatment, sewerage, heating, air conditioning, control of vibrations and noise on pipes etc.

GENERAL CHARACTERISTICS

- From DN15 to DN600.

- EPDM rubber bellow.
