Main features

Main characteristics:

  • Elastomer ring type NBR or EPDM type (for drinking water)
  • The flow ring is not a sealing ring and does not provide this function
  • The flow ring must not be used in an UNIVERSAL socket
  • The flow ring does not change the pressure performance of the joint
  • The limits of angular deflection of the joint equipped with the flow ring are given in the table above

Field of use:

  • Protection against abrasion: the flow ring regulates the flow rate of the fluid in the joint and in its immediate extension. It considerably reduces the abrasion phenomena in the jointing area when the transported fluid has an abrasive character. Its use is recommended according to the table Figure 3 below.
  • Shock protection: occasionally, the flow ring can be used as an impact shield in cases where there is a risk of impact of the spigot on the socket bottom: - Clamping force difficult to control due to the configuration of the site or the use of inadequately precise piloting gear. The ring protects against the risk of impact between the spigot and the socket bottom - Installation in very strong slope with assembling of pipes from downstream to upstream. The ring serves as a support for the spigot of the upstream pipe on the bottom of the downstream pipe
