Technical Report: Grade 91: Is it passing the test?

  The use of modified 9-Cr (Grade 91) steel in modern power plants is derived from the unique properties of the material in comparison to carbon steels or lower chrome materials. Assets such as superior creep and tensile strength characteristics allow for the use of thinner materials in the design and manufacturing of piping systems

Pipe Support Integrity as Applicable to Piping System Safety and Performance

Main Steam, Hot Reheat, and Cold Reheat piping represent critical systems which can be subject to catastrophic failures. These lines transport steam to and from the boiler and turbine. The pipe leads range up to several hundred feet in length and may be as much as over 5″ thick. The loads on some hangers can

Overcoming the hurdles of prioritizing inspection locations.

High Priority: Inspection Locations High-energy piping systems are essential to the safe and cost-effective operation within modern power plants. The propensity for piping problems and failures tends to increase with the age of the systems. Prolonged operation, particularly at elevated temperatures, may result in metallurgical degradation. Metallurgical degradation may increase the potential for cracking and
