RACI™ joints & flange adapters

Universal joint suitable for connections between spigotend pipes made by different materials, with same DN but different outlet diameters.

Universal joint

A comprehensive range of couplings to suit the various
outside diameters of pipes with nominal bores between DN
40 and DN 300 (e.g.: steel with ductile or cast iron, cast iron
with asbestos cement, steel with PVC), no need for seal ring
replacement. Pipes of diverse materials and outside diameters
can be connected by one single joint, it considerably
reduces supplies held in warehouse

     

  • Perfect tightness even on piping with uneven surfaces.
     

  • Easy to install
  •  

  • Savings on installation costs thanks to quicker mounting
    times afforded by small-section excavations
  •  

  • The high adhesion and impact resistance characteristics
    offered by the Rilsan coating of body and ring nuts eliminates
    the need for additional on-site coatings
  •  

  • Maximum operating temperature: 70°C
  •  

  • Maximum operating pressure: 16 bar
  •  

  • Test pressure: 24 bar
  •  

  • Tightening torque: 55÷65 Nm
  •  

  • Maximum pipe axial movement allowed by seal distortion:
    10 mm
  •  

  • Maximum pipe angular aeflection: ±6 on each end of the
    joint, to absorb any ground settlement

All metal, rubber, and coatings used have been designed
for contact with water for human consumption, pursuant to
the terms of the Italian Health Ministry Decree no. 174 of
6/4/2004.

Flange adaptor

Universal joint with a flanged end and a coupling-type end on the opposite side, suitable for interconnecting a flanged pipe with a smooth-end pipe made of different material but with same rated diameter.

Flange adaptor designed to join pipes of various materials
(e.g.: steel with ductile or cast iron, cast iron with asbestos
cement, steel with PVC), and outside diameters to flanges of
the same or different nominal bores, with no need to replace
the seal ring. Pipes of different materials and outside diameters
can be connected by one single joint, it considerably
reduces supplies held in warehouse.
