Dixon 08/048/18/000 2" (50 mm) Shouldered Weld Ring - Mild Steel

This Dixon shouldered weld ring is a ring that is welded onto a plain pipe end to form the shoulder that a bolted shouldered coupling grips. It is mild steel, and the store lists six sizes from 50 to 200 NB, including a 150 mm USA size (manufacturer-stated).

Dixon prints the pipe OD, the ring outside diameter (OD) and the ring width (W) for each size. The ring OD runs from 66.5 mm on the 50 NB to 232.0 mm on the 200 NB, and the 150 USA ring fits a 168.3 mm pipe OD with a 178.0 mm ring OD. Dixon lists these parts as shoulder rings (manufacturer-stated).

Common specifications

Key specifications

The 150 USA ring is for a 168.3 mm pipe OD; the standard 150 NB ring is for 165.1 mm. Do not mix them. The larger 250 to 600 NB sizes are the split rings, listed as a separate product.

Selecting the right option

Pick the ring by pipe OD, not by nominal size alone, particularly at 150 NB where there are two pipe diameters. The bolted coupling clamps behind the shoulder, so the weld matters. Welding is work for a qualified welder.
