Ensuring Safe and Reliable Operation of High Energy Piping

摘要

In the mid-1980s the power industry experienced high energy piping (HEP) system failures that resulted in personnel injuries and fatalities, as well as damaged equipment and loss of power generation. Power industry leaders worked together with the Electric Power Research Institute and the Materials Property Council to study HEP failures, to understand the causes and to develop resources for avoiding future failures. At that time, experience revealed that construction code criteria and available applications of non-destructive testing methods (NDE) could not provide relevant information regarding failure mechanisms. PacifiCorp has actively managed HEP since the mid-1980s. In 2007, PacifiCorp renewed its commitment to effectively manage HEP. The foundation of PacifiCorp's new HEP program is a document entitled "The PacifiCorp High Energy Piping Safety and Reliability Program". A power company's insurability, deductibles and pricing for boiler/machinery insurance are determined by risk ratings.
