Scale latched on the outer surface and progressively thinning thickness with a minimum thickness of tube rupture at the nearest corner. An analysis of this research is to find the cause fracture mechanism and prevent similar failure. The mechanical analysis used tensile and impact test on failure and replacement tubes. Quantitative data analysis used descriptive methods. Characteristic of tube SUS347HTP with tensile strength standard 550N/mm2. The yield strength obtained on replacement tube, temperature 30 (399.55Mpa), 160 (234.09 Mpa), 290C (198.13Mpa), 4200C (136.26 MPa), 500C (102.10Mpa), 550C (80.75 Mpa), 580C (67.94Mpa), and 600C (59.40MPa) and on failure tube, temperature 30C (244.45MPa), 160C (206.93MPa), 290C (158.70 MPa), 420C (118.14Mpa), 500C (91.9MPa), 550C (75.5MPa), 580C (65.66MPa), 600C (59.10MPa). Tensile test aimed that pressure of failure tube decreased. Impact test showed that low toughness of failure tube. The Combining tensile and impact data analyzed, the result shows ruptured the reheater tube at this location because it decreased in mechanical strength and hardness value. It shows material (tube) could not hold up the allowable pressure.","PeriodicalId":301056,"journal":{"name":"Proceedings of the International Joint Conference on Science and Engineering (IJCSE 2020)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117046779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
