Course Description

O-BOI10103

Boiler - Elements of High Energy Piping (HEP) System 

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.

Duration

2 Days

Target Audience

  • Supervisors
  • Operations
  • Mechanical Maintenance

Prerequisites

  • Instruction is given in English; therefore, a reasonable ability to read and understand spoken English is required

Class Size

Maximum number of students:  18

Learning Objectives

This course will provide basic knowledge on the following:

  • Describe the damage mechanisms of greatest concern affecting high energy piping, including:
  • Creep
  • Fatigue
  • FAC
  • Identify the main differences between P-22 and Grade 91 materials
  • Describe the strengths and weaknesses of Grade 91 material
  • Identify the drivers for the move to Grade 91 material in design
  • Describe techniques available to discern aberrant Grade 91
  • Non-destructive
  • Destructive/metallurgical
  • Engineering evaluation
  • Explain new requirements for plant owners as a result of changes to B31.1
  • Ensure that HEP inspections and repairs are compliant with B31.1
  • Explain techniques useful to identify and rank locations to be examined in HEP systems where Grade 91 is used
  • Develop an ongoing plan to maintain reliable operation of these components

Course Content

LESSON

The lessons focus on the following systems and equipment:

  1. High energy piping
  1. Historical records
  2. Hot and cold walk downs
  3. Hanger inspection details
  4. Piping stress analysis
  5. Material properties
  6. Inspection techniques
  7. Risk analysis

    B. High energy piping with Grade 91 materials

     C. Incorporate a much more rigid/ comprehensive evaluation, including:

  1. Historical records
  2. Pipe stress analysis
  3. Risk analysis
  1. Additional inspection techniques

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.

  1. High energy piping Grade 91 fundamentals and operating characteristics will be addressed from multiple perspectives:
  1. High energy piping design principles
  2. Grade 91 design principles
  3. Welding shop/field issues
  4. Support system expansions
  5. Cyclic operation and impact on component movement and life
  6. Risk ranking criteria
  7. Inspection techniques and locations
  8. Importance of an on-going isometric drawing of the high energy piping system
  9. Data management and re-inspection management process
