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 eqipment in a pipe line during installation and dismantling as the telescopic action between the inner and outer flange bodies allows for longitudinal adjustment
- Designed with three flanges connected with tightening rods; the centre flange applies compression on the seal through the rods
- 50 mm axial adjustment
- Ductile iron with coating of fusion bonded epoxy
- Tightening rods of zinc plated and passivated 8.8 steel
