Orifice carrier assemblies mount an orifice plate in a carrier with integrated differential pressure tappings, designed to fit between raised-face flanges. Standard pipeline sizes range from 25 to 600 mm (1 to 24 in.), with larger sizes available on special order. The integral type is a one-piece assembly with corner tappings, while the split-ring type allows orifice plate replacement without replacing the carrier. Materials include 316 stainless steel or carbon steel for the carrier and stainless steel for the orifice plate. Tappings are standard 1/2 in. NPT, with alternatives available. Assemblies comply with ASME VIII and ISO 5167-1:2003, and support full NDT, material certification, and PED 97/23/EC documentation.
Each assembly comprises an orifice plate mounted in (or integral with) a carrier that already has the correct tapping points fitted.
