Socket Weld Tees are used in small bore piping networks up to size 2″, though fittings up to 4″ size are available as per ASME B16.11 : Forged Fittings, Socket Welding and Threaded. These fittings are available in three pressure ratings viz. 3000#, 6000# and 9000#. This page provides metric dimensions for 3000# rating tees.
Available Dimensions : A | Center to Bottom of Socket, B | Socket Bore Dia, C | Socket Wall Thickness, D | Bore Dia of Fitting, G | Body Wall Thickness, J | Depth of Socket, A Tol. | Tolerance of value A.
