Viking Johnson flange adapter UltraGrip DN400 398,2-442,0 mm NBR

For connecting non-dedicated pipes of different materials, the UltraGrip series from Viking Johnson is an excellent solution. The gripping mechanism ensures maximum grip around the entire pipe circumference and is therefore resistant to axial loads. With increasing internal pressure, the gripping mechanism can hold more end loads. In addition, UltraGrip can be converted into a flexible, non-restraint product with axial movement by removing the grippers.

Application

The UltraGrip flange adaptor can be used on a wide range of pipe materials, including steel, PE, PVC, steel, cast iron and AC (AC restraint is not guaranteed), in accordance with EN 14525. The flange bore is according to EN1092 PN10/16. This flange adapter has a DN 400 flange on one side and has a restraint, wide range connection of DN 400 on the other side. The size range of this connection is minimum 398,2 mm to maximum 442 mm. In addition, this flange adapter is suitable for gas up to PN 5 due to the gasket of NBR.

Product Features

The UltraGrip flange adapter is made of ductile iron with a rilsan nylon 11 coating, which makes the coupling resistant to abrasion or damage from corrosion or chemicals. In addition, even damaged and corroded pipes can be completely sealed by the specially profiled gasket. For the UltraGrip side, a support liner is recommended when used on a PE pipe. Furthermore, within the entire size range of the UltraGrip coupling, an angular deflection of up to 4° is possible.
