Primary Flow Signal, designer and manufacturer of innovative, durable, and accurate flow-metering solutions, has successfully delivered a 96 in. ASME PTC 19.5, throat-tapped flow nozzle for use within the largest gas turbine validation facility in the world.
Once installed in the facility鈥檚 test stand, the flow nozzle will be subjected to simulations of real-world power connectivity and testing well beyond critical limits of normal plant operations.
The first flow nozzle has been shipped and orders have been placed for additional nozzles, giving the facility significantly more accurate measurement of the high airflow output required for testing H-class gas turbines. This very large line size nozzle was manufactured at the company鈥檚 Rhode Island facility using a combination of 304 stainless steel and fiberglass. The nozzle features four equally spaced taps at the throat for a variety of instrumentation required for a specific test.
鈥淲hen we were approached by a global gas turbine manufacturer to assist with improving accuracy for their test stand, we were extremely excited by the engineering challenge it would present,鈥� said Kenneth P. Fountain, Business Development Manager of Power & OEM Markets at Primary Flow Signal. 鈥淓ven though this meter must adhere to specific standards, the customer noted that our engineering expertise and reputation for high-quality manufacturing was a deciding factor when choosing us for this project.鈥�
Primary Flow Signal鈥檚 PTC 19.5 and PTC-6 flow elements are high performance, reliable, differential-producing flow measurement devices that are intended to be the primary device for steam turbine acceptance tests. The meter was specifically designed and manufactured in accord with the requirements of the ASME Performance Test Code 19.5 for Steam Turbines. These nozzles are available in flanged and weld-in styles, and feature interior surfaces that are precision machined for cylindricality and a hydraulically-smooth surface. For weld-in flow nozzles, a code-recommended inspection port with a removable, contoured pin oriented plug is available.
PFS鈥檚 metering solutions are designed and manufactured in the United States by the industry鈥檚 largest team of specialised hydraulic engineers, backed by extensive laboratory and field testing, ISO 9001-2008 certification, and efficient vertically-integrated facilities. PFS鈥檚 products deliver a level of differential metering accuracy, reliability, and versatility, coupled with unparalleled engineering support, simply not available from other metering solutions.
