Polyguard Products, Inc.
IRO Impact Resistand Outer Wrap IRO can be used in may instances, the most common is over corrosion coatings when pulling a pipe through a bore or road crossing culvert. It can also be used over jacketing on piping systems in areas where pipes commonly get walked on or crawled over crossing a roof. For un-insulated lines which RG-2400 is installed, a paintable hard surface may be desired. Install RG-2400, install GeoWrap, then install IRO over the surface, activate, and let harden. The IRO can then be painted to match any... (read more)Browse Industrial Coatings Datasheets for Polyguard Products, Inc. -

What is Synchronous (Angular) Sampling? of the fundamental (once per revolution) rotation speed frequency. These associated speeds are known as orders, with the 1st order being the once-per-revolution speed and a second order vibration being one that vibrates harmonically at twice-per-revolution and so on. In order to capture data at regularly spaced angle intervals one needs either a tachometer or shaft encoder that can generate an electrical pulse every time a threshold crossing is detected due to angular motion of the rotating...
