Key specifications

Choosing 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.

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