Modeling ISO 156656 Large Diameter Industrial Pipe Insulation



As previously presented, reducing industrial noise emission utilizing jacketed pipe insulation is critical to reducing noise in industrial spaces.  The ISO 15665 standard defines a testing process for measurement of the acoustical performance of installed and jacketed pipe insulation systems.  To provide a cost-effective method for evaluating various types of multilayered jacketed pipe insulation a model was developed.  The model accurately estimates the performance of single, and multilayered, jacketed pipe insulation.   Validating the use of the model to very large pipe diameters is highly desirable as the cost to test is significantly higher than testing the medium or small diameter pipe insulation.  The estimated insertion loss result from the model is compared to validation testing results for large diameter jacketed pipe insulation are reported herein.
