EF Spigot Air Saddles

Black Spigot Saddle / SA UNI / PN16 / SDR11

The Friatec SA UNI electrofusion spigot saddles are typically used for attaching air valves via a flanged connection. The SA UNI can be installed during construction or post-construction when the pipeline is under normal operating pressure.  Connections can be made 'live' using under pressure tapping equipment.  This prevents the main having to be shut down during the installation process.

Pressure test of the saddle after fusion is recommended, before drilling the tapping hole into the main pipe via integrated pressure nozzle and pressure test adaptor - FWDPA.

Assembly is conducted using the FRIATOOLS clamping unit UNITOP. Tapping in the unpressurised condition can be achieved using the correct size hole saw. 

The transition to the flange for connecting the isolations valve and air valve assembly is made using a standard Coupler and Flange adaptor onto the saddles spigot outlet.

NOTE: The pipe surface must be prepared in accordance with the general installation instructions using a mechanical saddle peeler, 90% Isopropyl alcohol wipes and we recommend using the Friamat fusion control unit to achieve correct preheating and logging the full range of weld data available.
