Fire Protection Sprinkler Systems
Used for seismic bracing of fire sprinkler piping to satisfy NFPA13 code requirement, prevent pipeline offset under seismic shaking.
MEP & HVAC Engineering
Restrain domestic water, drainage and HVAC pipeline lateral displacement for high-rise, shopping mall and residential buildings.
Critical Industrial Facilities
Specified for hospital, data center and chemical factory projects with high seismic design category D/E.
Fasten UTT11 base firmly onto building structural steel with matched bolt.
Insert 1” Sch40 standard brace pipe into the bottom slot of UTT11 fitting.
Lock brace pipe by specified shear bolt and tighten until bolt head breaks off.
Connect the other end of brace pipe with UTT20 pipe clamp fixed on pipeline.
Double-check all connection tightness before pipeline pressure test.
UL2039, FM1621, CE full certification approved
Fully comply with NFPA13, IBC and ASCE7 North American seismic standards
Electro-galvanized coating meets ASTM B633 anti-corrosion specification
Every production batch passes factory load inspection and dimensional test
