Black Fabricated Air Tees

Fabricated Air Valve Tees / PN16 / SDR11

Fabricated Air Valve Tee's are manufactured by machining PE100+ hollow bar into a fitting body that includes external reinforcement and then welding on CCTV pipe spigot ends in accordance with BS ISO 21307. Fabricated Air Valve Tee's feature long spigots for electrofusion or butt fusion joining and 1D and 2D bar code stickers for complete product traceability.

The main advantage with Fabricated Air Valve tees is regardless of the mainway size, the air offtake size can be small (DN80 offtake on a DN1800 Main). Traditional tees do not offer such large step changes, so require several reducers which take up precious height above the pipeline. The transition from the Tee to the flange connecting the isolation/air valve assembly is made using a standard Coupler and Flange adaptor onto the Tee's spigot outlet or if space is extremely tight, the tee can be fabricated with a flange adaptor butt welded directly to the offtake.

See an example of our fabricated air valves tees being used in a sewer rising main at Hong Kong International Airport here.

NOTE: The spigot ends must be prepared in accordance with the general installation instructions using a spigot mechanical peeler, 90% Isopropyl alcohol wipes.
