Failure investigation on deformed superheater tubes
Investigation is conducted following the discovery of significant deformations and the presence of cracks in the vicinity of welded joints at the superheater tubes of a heat recovery steam generator (HRSG) in a Malaysian Electricity Company's power plant. This study performs the finite element...
