Orifice Flange Unions

Flowell Orifice Flange Unions provide an economical method of measuring flow in both gas and liquid services. Flanges are machined in accordance with the requirements of ANSI B16.36. Raised face flanges meet the requirements of ANSI B16.5 for raised face dimensions. Our standard pressure taps, bore tolerances and surface finishes are all in accordance with the requirements of both API 14.3 and ISO 5167. Full compliance with these more stringent specifications can be provided if required. This is achieved with the addition of precisely machined dowel pin holes in each flange to assure maximum concentricity. Standard materials include carbon steel flanges and bolting with 1/16″ thick non-asbestos gaskets. Other materials and gasket types are available on request.
