Supa Maxi™ - specialversion av flänsadaptern och ändhuven

AVK launches special versions of our reowned Supa Maxi™ flange adaptors and end caps in order to meet special market needs 26-03-2019

Series 633 flange adaptor - DN 80 flange X DN 100 coupling 

The special version of the DN 80 of Supa Maxi™ flange adaptor is suitable for connecting a DN 100 pipe to a DN 80 fire hydrant with flange connection. It eliminates the need for extra reduction flanges.

Series 634 end caps – DN 50 and 65 in short design 

The short end caps have been developed to meet requests from Danish customers for a light- weight model. In Denmark end caps in DN 50 and 65 are widely used as transition couplings from old pipes to threaded connections with brass compression fittings. Since end caps with inline thread are used for this purpose, the dedicated versions are designed without space allocated for a 90 degree thread, and they are therefore shorter than our standard end caps.

AVK’s Supa Maxi™ range comprises tensile universal straight couplings, flange adaptors, step couplings, end caps and transition couplings in DN 50-300, suitable for water, wastewater and gas applications. The unique patented SupaGrip™ sealing support system deals with well-known challenges. SupaGrip™ features a flexible bracket that:

• contracts and follows the external pipe diameter even on oval pipes and minimum pipe sizes

• enables full deflection of ±4° on each side at up to 1.5 x PN test pressure

• safeguards the sealing compression over time and eliminates the need for re-tightening bolts

All dimensions are in PN 16 for water and PN 10 for gas. Supa Maxi™ is designed to EN 14525, the new standard for universal tensile couplings. Tightness and tensile resistance are tested according to this norm with 1.5 x PN 16 + 5 bar = 29 bar, and the couplings have undergone a series of additional comprehensive tests to verify suitability in all foreseeable applications.
 On top of this built-in safety, additional features such as permanent protection caps, lifting eyes, and optimized bolt design secure durability and easy installation.
