At the end of 2018, for a flow measurement application in India, the WIKA Group manufactured a PTC-6 nozzle with a diameter of 18 inches for the first time – and in a record time of just 20 weeks.
he overall length of this nozzle, including upstream/downstream piping, is 13.3 metres.
The order was executed for a supplier in the energy industry based in Singapore. The production required a high degree of precision. The customer was able to rely on WIKA’s many years of expertise in the field of flow measurement and, in particular, in the production of flow nozzles.
Manufacture of the flow nozzle
This ultra-long nozzle was manufactured in a record time of just 20 weeks. An important milestone was the successful calibration in the in-house flow laboratory, traceable to national standards. Making the flow nozzle posed some challenges. The major challenge was honing the pipe lengths to maintain the desired levels of finish. The design of the nozzle was also optimised so that the required results could be achieved.
Outlook: order for 22-inch nozzle
Following successful completion, as a flow specialist, we have already received another order for a PTC-6 flow nozzle – with a 22-inch diameter. A new chapter for the WIKA Group, where we can now position ourselves as a key supplier of flow nozzles for use in steam boilers.
