Hanging and Bracing
Overview/Description
This self-paced online training course covers requirements for the hanging and bracing of fire
sprinkler piping, including materials used, types of hangers, and calculation methods for trapeze
hangers. Hanging and bracing of sprinkler piping is one of the most important aspects of the
design and installation of automatic fire sprinkler systems. It is also one of the least
"respected" components, and the inspection and maintenance of the braces is often overlooked.
Upon completion you should be able to:
- Explain how earthquakes have affected the development of hanging and bracing
requirements
- Explain the use of performance-based design approaches for hanging and bracing
- Define and explain key concepts, including section modulus, trapeze hangers, and branch line
restraints
- Explain requirements for trapeze hangers
- Explain allowable fastener types and fastener requirements for various construction
types
- List the components of a sprinkler system hanging system that do not have to be listed for
fire protection service
- List the amount of weight a normal sprinkler system hanger must carry
- Define and explain the use of post-installed anchors, powder-driven studs and coach rods
- Explain how to determine the size of lag bolts and screws for system hangers
Who Will Benefit
Anyone whose job involves designing, reviewing, evaluating or installing fire protection
systems, including: designers, installers, engineers, electrical contractors, technicians,
project managers, fire marshals, and architects.
Course Summary
- Hanging and bracing is a very important aspect of the overall fire sprinkler system
design. It is also one of the least "respected" components, and the inspection and
maintenance of the braces is often overlooked.
- Ascertaining the structural abilities of the building is often required, so you can
verify that the structure will not collapse under the weight of the water-filled sprinkler
system.
- Occasionally, piping cannot be suspended along or from a single structural support and
must be suspended from the building structure using a trapeze hanger. NFPA 13 provides direction
for building the appropriate assemblies. The use of trapeze hangers is quite
prominent.
- The support of non-fire protection system components from fire sprinkler system hangers
is not allowed.
- Hangers for sprinkler piping must be located in accordance with minimum requirements of
NFPA 13 based on the diameter of the pipe size being suspended. There are specific tables for
types of pipes and pipe diameters which state these maximum spacings. The suspension of
unsupported lengths of pipe (ends of piping) are also addressed, specifically for end of lines
and the ends of arm overs.
