Flange and nut

In a climate engineering installation, the sealing and flexibility of connections are essential. Flanges, tightening nuts, flange gaskets, and expansion joints: these hydraulic connection parts guarantee the integrity of the network against pressure variations and thermal movements.

On Expertbynet.fr, find a comprehensive range of flanges, gaskets, and expansion joints available in different nominal diameters, to equip your boiler room according to the rules of the art and in full compliance.

In climate engineering, various spare parts allow connecting taps (gas valve, hydraulic valve, ...) and ensuring sealing.
For this, you may need a flange, usually made of steel and meeting a certain nominal pressure (for example, a PN10 flange).
The nut is tightened on the installation, taking into account the necessary diameter.
As for the flange gasket, check the thickness that fits your installation with the nominal diameter: a 1-inch flange gasket corresponds to DN25, while a DN20 flange gasket corresponds to 3/4 inch.
The expansion in the heating installation is a risk, which is why an expansion joint should be installed also taking into account the nominal diameter.
