Permutit® Power Products have been the trusted source for all grades of nuclear and commercial flow straighteners and other components for many years.  Our capabilities include dissimilar metal welding and fabrication to ANSI and RDT specifications.  We meet the requirements of the ASME Codes and 10CFR50, Appendix B, through our stringent quality assurance program.




Uses

Flow straighteners are used to correct the flow distortions that cause inaccurate flow meter readings. The accuracy of the flow meter is dependent upon the flow profile of the fluid as it passes into and through the measuring device. The pipe layout, pipe fittings, expanders and strainers cause distortions in the flow profile. Such distortions can be eliminated by providing an adequate length of straight pipe before the meter or by the use of flow straighteners.

Applications

Permutit® MHI Flow Straighteners are used in liquid, gas or steam applications in virtually all types of closed pressure piping where flow profile correction is required. They can be installed in new or existing systems to ensure accurate flow metering. Appropriate for a wide range of boilers, from low pressure to supercritical, they are utilized in both fossil fueled and nuclear power plants.
