Flange connections reliably distribute pressure impulses in hydraulic systems such as presses or aluminium extrusion plants. In addition, the large diameter of the flanges compared to pipe fittings allow optimum fluid flow with little turbulence.
The seal between the two flange halves under pressure ensures there are no leaks at the hydraulic connection. HANSA‑FLEX uses oil-resistant materials such as NBR or Viton for its O-ring seals. Other materials for flat-face seals are available on request.
In particular for large diameters, flange fittings can be installed in considerably less space than is required for other screw-in fittings. The lower tightening moments can be achieved without large wrenches, which is a great advantage when working in congested installation spaces.
