Dismantling joint of ductile iron with centre flange, PN25. For water and wastewater at temperatures up to 70° C

AVK dismantling joints are designed to compensate for axial displacement of a pipe during installation and dismantling. This provides for easy installation and disassembly of flanged pipework and fittings or flanged equipment such as valves, meters and pumps.

Variant 873/00-002
Connection: Flanged
Material: Ductile Iron
DN: DN40 - DN1200
PN: PN 25

Features

  • Compensates for axial displacement of the pipe during installation and dismantling as the telescopic action between the inner and outer flange body allows for longitudinal adjustment
  • Designed with three flanges connected with tie-rods; a centre flange applies compression on the seal through the tie-rods
  • 50 mm axial adjustment
  • Ductile iron with coating of fusion bonded epoxy
  • Tie-rods of zinc plated and passivated steel 8.8
