Application Scenarios
Fire Protection Sprinkler Systems
Specialized seismic bracing for fire sprinkler piping to meet NFPA13 requirements, avoid pipeline deformation and offset under seismic shock. MEP & HVAC Engineering
Restrain cold/hot water, drainage and HVAC pipeline lateral shift for high-rise, shopping mall and residential construction. Critical Industrial Facilities
Matching pipeline support for hospital, data center and chemical factory projects with high seismic design category D/E.
Step-by-Step Installation Guide
Secure base tightly onto building structural member with M12 bolt and control tightening torque within 50~65N·M.
Put 1” Sch40 standard bracing pipe into the bottom clamping slot following specified installation direction.
Install specified shear bolt and keep tightening until bolt head breaks to complete fixed locking.
Connect the other end of bracing pipe with series pipe clamp mounted on outer pipe wall.
Inspect all connecting tightness before pipeline hydraulic pressure test.
Note: Perfectly matched with full series pipe clamps, hinges and strut accessories for complete seismic bracing system.
