Combi Flange PE/PVC, AVK

Combi Flange PE/PVC, AVK

Combi-flange tensile unit for PE/PVC and Bi-PVC pipes. For drinking water and neutral liquids to max. 70°C
AVK’s combi-flange system comprises tensile combi-flanges for PE, PVC and ductile iron pipes as well as non-tensile combi-flanges for PVC, steel and ductile iron pipes. The design features a flexible positioning and chamfering of the pipe and a big angular deflection. The EPDM rubber sealings are approved for drinking water applications and the flanges are fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN 14901.

Features

• Flexible positioning of the pipe with the large buffer zone clearly marked on the sealing
• Easy pipe chamfering allowing the pipe to be cut unevenly or out of angle, as long as it stays within the buffer zone
• Barrel-shaped rubber sealing allows for up to ±3.5° deflection of the pipe
• The pipe will not move inwards during installation which helps securing a tight connection
• The EPDM rubber sealing is approved for drinking water applications
• The rubber is resistant to water treatment chemicals and features an excellent compression set, meaning the ability to regain original shape
• The sealing is supported by a sleeve of polypropylene
• The wide tension ring combined with the special lip profile on the sealing ensure full tensile abilities on all PE and PVC pipes, even thin wall PVC pipes (Bi-PVC).
• A support bush must be used in PE pipes to avoid deformation of the pipe
• Flange of ductile iron is fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN 14901
• Flange and gasket are packed as a complete unit
• Design pressure 29 bar according to EN 12842. Working pressure max. 16 bar. Max. test pressure according to pipe standard.
