Safety valves are an important part of any boiler or pressure vessel. Some might say they are the most important part. They are the last line of defense against a catastrophic explosion due to accidental over-pressuring of a pressure vessel. The applicable codes and standards for safety valves on boilers, pressure vessels, and pressure piping are set forth by the American Society of Mechanical Engineers (ASME), the National Board of Boiler Inspectors (National Board), and the American Petroleum Institute (API).
A boiler is any pressurized vessel designed to heat water and produce either very hot water or steam. The heat source can be electric, coal, oil, natural gas, wood, or just about any substance that can be burned to produce heat. These are referred to as fired boilers. The heat source can also be the bi-product of another process that is used to heat water. This is called a non-fired boiler.
This course will review the rules for safety valves used on boilers, which are covered by ASME Section I Code and the National Board Inspection Code. The course will discuss how to determine the capacity requirements of a boiler, how to choose the set pressures of the safety valves on a boiler, design requirements of safety valves that are used on boilers, and installation guidelines for safety valves on boilers. Set pressure tolerances, recommended operating gaps, and blowdown will also be covered.
The course also discusses recommended testing and inspection intervals and practices. Only qualified companies are authorized to work on safety valves. The course outlines what makes a company qualified to work on safety valves and provides an overview of what is involved in repairing a safety valve.
Finally, the course examines some popular safety valve designs, as well as the parts of a safety valve and how they all work together to make the valve operate correctly. The steps involved in sizing and selecting a safety valve for an application are also reviewed.
Several examples are provided in the course to better illustrate the concepts presented.
Learning Objectives
Upon completion of this course, participants will be able to:
- Describe boiler safety valve installation guidelines, including connecting vent piping.
- Identify safety valve set pressure tolerances.
- State the recommended gap between boiler operating pressure and the safety valve set pressure.
- Explain the circumstances under which an ASME Section VIII safety valve can be used in a Section I application.
- Describe how the ASME Code treats pilot-operated safety valves.
- Identify recommended test frequencies for boiler safety valves.
- Explain how safety valves are certified and tested.
- Determine if a company is qualified to test and repair boiler safety valves.
- Describe the basic design and operating principle of a safety valve for use on a boiler.
- Explain safety valve sizing and selection.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 20 questions. PDH credits are not awarded until the course is completed and quiz is passed.
