Restraining Duct & Pipes

A key factor in effective piping and ductwork restraint is site planning and coordination prior to installation. A first step is choosing between cable or rigid brace restraints. Selecting the proper restraint system requires a study of piping or ductwork placement and an examination of site conditions, including wall and ceiling location and construction.

Seismic Pipe Stands

Our seismic pipe stands allow for quicker and easier pipe installation, and provide the required seismic resisting force when supporting the dead load.

Component	Design Considerations
Indoor piping and ductwork	If contents are hazardous, restraint locations and quantity will be affected
	A determining factor for restraint locations will be whether the pipe is constructed from ductile or non-ductile materials
	Anchors must be approved for seismic restraint
	The restraint system needs to be attached to the building structure
	Confirm that restraint anchor location (wall, beam, column, or slab) can withstand seismic load
Piping & ductwork risers	Should be restrained to shaft walls or floor slabs with structural members and anchors
Rooftop piping and ductwork	Transverse and longitudinal restraints need to be attached positively to the structure
Rooftop piping and ductwork	Restraint supports need to be connected properly to the roof system
