Abstract
In this study, we determined TBP(T-branched pipe) would be available in Fire Safety Codes with strength analyses. A common FEM Program(ABAQUS) was used as analyses method, and the analyses results were confirmed by strength tests of the T-branch pipe. As a result, we concluded that the T-branch pipe can be used safely. Further more, we determined what kind of stainless steel pipe can be used in place of carbon steel pipe(KS D 3507). The stainless steel pipe name Is KS D 3576(stainless steel pipe) 10S, so they can be applied for piping in fire protection system.
