Buttweld tee fittings have the same diameter vacuum tubing on all three ports.
Tees are a common component of vacuum piping systems and are used to provide
a 90 degree branch.
-Butt weld tee fittings
-304 Stainless Steel construction
-0.5 to 6 in. vacuum tubing diameters
-Low outgassing under vacuum
-Annealed for consistent leak free welding
-Minimized corrosion concentration points
-Cost consistent with the above requirements
Series 23 fittings are designed to be welded using techniques preferred for vacuum applications. These techniques include internal (socket type) welding and external buttwelding. The most commonly used type of weld for high vacuum applications is a TIG (Tungsten Inert Gas) fusion weld, preferably without filler rod. For the best results, remove components from packaging in clean conditions during installation. Handle the components with clean gloves and equipment in the absence of any fibers, fingerprint oils, or other greases. If these precautions are taken, the weld is more likely to be leak free and the integrity of the vacuum surface will remain intact and ready for use.
General hints for good vacuum welds include:
1.Always start with clean and properly weld prepped components.2.For internal welds, minimize warping by using only enough heat for 60-75% penetration.
5.Make sure there is little or no gap between pieces to be welded.
6.Ensure that all surfaces affected by the heat of the weld, especially the vacuum side, are purged properly with inert gas.
