Flow Nozzle

The ASME Flow Nozzle is a high performance, reliable measurement device that can be installed in various design and material configurations with conformance to ASME MFC-3M, ASME PTC-6, and ASME PTC 19.5 codes.

The PTC-6 ASME Flow Nozzle provides high accuracy and precision required by ASME PTC-6 in steam turbine testing applications.  The assembly consists of a flow conditioner for added accuracy, a diffuser cone for reduced pressure loss, and either a flanged or weld-in flow nozzle.

Available in line sizes 4” to 24” (101.6mm to 609.6mm) with perforated plate or tube bundle flow conditioner, flanged-in or weld-in end connections, and four integrally machined throat pressure taps that are precision-machined and polished.

Design standard ASME PTC-6 or ASME PTC 19.5.
