AVK SUPA MAXI™ TRANSITION COUPLING, PE 100 / PN 10

Features

• Patented SupaGrip™ sealing support system with flexible bracket ensures full support of the gasket even at minimum pipe size
• Full tensile strength on all pipes is ensured by two different metal grip segments - every other of gunmetal for PE/PVC and of hardened stainless steel for cast iron/ductile iron/steel/stainless steel/GRP/asbestos cement pipes. For PE pipes a support bush is to be used.
• Metal grip segments are mounted with pins for maximum durability
• ±4° angular deflection at max. 1.5 x PN 16
• Large tolerance ranges
• All DNs are for PN 16 (stainless steel, AC, Bi-PVC, and CFW GRP pipes max. PN 10)
• Ductile iron body and bracket of cast steel, fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN 14901, GSK approved
• Gasket of drinking water approved EPDM rubber
• Bolts and nuts of acid-resistant stainless steel A4 are anti-friction coated to prevent galling
• Permanent protection cap protects the coupling during handling and installation
• The pipe will not move inwards when tightening
• Bolts are tightened from the sleeve side for full access when space is limited
• Re-tightening of bolts is not necessary / Lifting eye in DN 100-300
• A standard DVGW approved PE-pipe is pressed onto the grooved end, locked with a steel ring and sealed with a plastic shrink hose. The PE pipe end enables direct welding into PE pipes by using socket fusion or butt welding. The assembly is as minimum as strong as the PE pipe itself.
• Design pressure 29 bar according to EN 14525. Working pressure max. 16 bar. Max. test pressure according to pipe standard.
• Note: The maximum working temperature of 20°C is set according to the ISO9080 lifetime requirements for PE pipes. For higher working temperatures expect a reduction of the PE pipe’s lifetime. Please refer to the local pipe manufacturer for further information.
