Heat Transfer Characteristics and Temperature Prediction Model of a Fire-stop System Using Metallic Piping

Abstract

Fire-related systems and laws are continually being strengthened to solve problems such as defective manufacturing and shoddy construction of penetration sealing systems, as these are factors that spread fire. However, due to insufficient facilities related to research and manufacturing, tests of performance-oriented products have failed to consider constructability and reasonable design modeling conditions necessary to solve these problems. In this study, we present a model that uses a mathematical formula to calculate the heat transfer phenomenon of a metallic pipe, where the model can then be used in product development performance tests. The theoretical model is verified through a comparative analysis of the error rates between the test and theoretical values. In addition, results of experiments to determine possible variables for use in product design are presented. The results of this study are expected to reduce time consumption and cost in product development testing.
