Соединения фланцевые EN14420-4/ DIN2817

 

Flange hose couplings are used to connect rubber, pvc and thermoplastic hoses.

A flange coupling is fitted to a rubber, pvc or thermoplastic hose using a hose shank coupling, which is inserted into the hose. The hose shank may be smooth in

compliance with EN 14420-2 / DIN 2817, or serrated with collar.

1.Flange couplings with smooth hose shanks complying with EN 14420-2 / DIN2817

are developed to comply with EN 14420-4, which makes them suitable for

assembly using RK and RKP safety clamps complying with EN 14220-3 / DIN 2817

or  FLEXOLINE®safety clamps for thin wall hoses.

2. Serrated hose shanks with collars are recommended for assembly using HRRK

swage ferrules, worm drive, band or bolt clamps. The hose shank can be assembled with a fixed or swivel flange. A flange-to-hose connection should preferably be fitted with at least one swivel flange. During assembly, the connection with the fixed flange is fitted to the piping system first, followed by the swivel flange. The swivel flange prevents twisting of the hose during assembly

To connect rubber, pvc and thermoplastic hoses.

TEMPERATURE: -20°C / -40°F up to 65°C / 149°F

Hose, coupling, assembly method and seal must be chosen in relation with the desired application and temperature.
