Boiler - Elements of High Energy Piping (HEP) System
Course Description |
The HEP/Grade 91 course is designed to benefit personnel recently assigned to the tasks of maintaining and evaluating these components/materials in accordance with the guidelines of ASME B31.1. The emphasis will be on the key aspects to ensure the safe and reliable operation of high energy piping (HEP). Special concerns related to Grade 91 materials are covered. This seminar will address utility, industrial and HRSG applications. |

LESSON
The lessons focus on the following systems and equipment: High energy piping
The central theme in this session is high energy piping failure mechanisms, causes and preventions. This course begins with an understanding of high energy piping purpose, configurations and materials selections. Topics focused on are design operating pressures and temperatures, zero-point expansion considerations, expansion growth and cyclic operation.
Information covered can be applied to coal, oil, gas, HRSGs and waste-fired boilers – industrial or utility.
High energy piping Grade 91 fundamentals and operating characteristics will be addressed from multiple perspectives:
