Application Scenarios
Fire Sprinkler Pipeline: Lateral anti-sway bracing for NFPA13 standard sprinkler piping in commercial buildings, malls.
MEP & HVAC Works: Seismic restraint for cold/hot water, drainage and ventilation steel pipes.
Industrial Construction: Pipeline anti-seismic fixing for factory, data center and high-seismic zone building projects.
Step-by-Step Installation Guide
Wrap UTT13 clamp over target sprinkler pipe, keep ≥6" distance away from any pipe joint per specification.
Insert 1" standard bracing pipe into clamp opening with minimum 1"(25.4mm) pipe extension outside fitting.
Adjust bracing mounting angle as site layout requirement, brace pipe can be mounted above or below service pipe.
Evenly tighten fastening nuts to 30~35N·M until all green indicator lines fully exposed.
Connect bracing pipe opposite end with UTT series structural attachment to finish full sway brace assembly.
