Fischer Seismic Bracing Elements - Designed for Fixation of Earthquake-Resistant Installation Systems

Flexibility is often required when piping crosses expansion joints or seismic separations. Each of the diverse installation systems' characteristics comes with a unique risk.

Pipes that are not properly supported or braced may fall or sway into adjacent equipment or structures. Breaks and leaks typically occur at joints, connections to equipment, bends, and penetrations, damaging the piping system and the adjacent equipment.

Damage can also be caused by differential movement between points of attachment, particularly in large industrial complexes. In the event of a quake, pipelines that are connected
to two or more buildings may react differently. It is crucial to consider the structural aspects of each building while designing seismic restraints at the interface between two structures.

Pipe bracing on the longitudinal side requires the use of seismic bracing elements that prevent pipe slippages, such as a pipe clamp, riser clamp, welded lug, and other hardware components.

U-bolts are not recommended for longitudinal restraints because of their highly prone to slipping. The pipe risers in multistore buildings are vertical runs of pressurized pipe. The majority of them are supported by wall-mounted supports and additional floor or roof-mounted supports where penetrations exist. The seismic restraints must be designed to accommodate inter-story drift and thermal movement. It is also essential to use seismic pipe clamps during constructions in earthquake-prone areas in order to protect the building structure from being affected by seismic activities.
