ARCMAC Optical Creep Monitoring: Developments in Image Analysis Techniques and Creep Measurement Validation

Autor: Chris Maharaj, John P. Dear, Iain Palmer, Andy Morris

Publikováno v: ASME 2010 Pressure Vessels and Piping Conference: Volume 7.

Power station steam pipes operate at high temperatures (approximately 570°C) and pressures, and estimation of remaining life is critical in avoiding pipe failure. In estimating remaining life, creep rate for both parent pipe material and weldments i
