Function: Designed for bracing pipe against sway and seismic disturbance. The pipe attachment component of a sway brace system used in conjunction with a UTT Manufacturing structural attachment fitting, and joined together with a bracing pipe element forms a complete sway brace assembly. Sway brace assemblies are intended to be installed in accordance with NFPA 13 and the manufacturer’s installation instructions.

UTT20Q longitudinal "In-Line" sway bracing attachment is a third-party certified seismic restraint component exclusively designed for fire sprinkler pipeline systems. Combined with UTT series structural attachments and 1-inch SCH40 bracing pipe, it forms a full set of longitudinal anti-sway bracing assembly to limit pipe displacement caused by seismic shock and building vibration, fully complying with NFPA 13 fire protection installation specifications.
This fitting adopts composite raw materials of high-strength carbon steel and QT450 ductile iron, with uniform electro-galvanized anti-corrosion coating to adapt to indoor mechanical rooms, mall ceilings, office buildings and other dry commercial construction environments. The complete size series covers DN50 to DN200 mainstream fire steel pipe specifications, with official UL maximum design load test data for each size, which can be directly submitted as technical bidding documents for North American fire engineering projects.
Restrains pipeline in the axial in-line direction, cooperates with lateral sway braces to realize all-round seismic protection for overhead fire pipes;
Carbon steel main clamp body + QT450 ductile iron connecting joint, strong impact resistance and stable long-term bearing capacity;
All load indicators pass official laboratory inspection, fully meet North American fire engineering acceptance standards;
Specified bolt tightening torque of 100~115 N·M ensures consistent clamping force and avoids pipe slipping under seismic load;
Covers 2" to 8" fire sprinkler steel pipes, unified supporting 1" SCH40 bracing pipe, convenient centralized material preparation for construction teams;
Simple assembly steps without special customized tools, effectively shortening on-site construction period.
The official standardized installation is divided into three clear steps:
Secure the UTT20Q pipe clamp tightly around the outer wall of fire sprinkler pipe;
Assemble matching bolts, nuts and connecting accessories in sequence as shown in schematic drawings;
Tighten bolts to specified torque 100~115 N·M, ensure the pipe is fully locked to the bottom of the clamp inner cavity to eliminate installation clearance.
The finished UTT20Q assembly can be connected with various UTT series structural attachments to fix on steel beams, anchor bolts and strut channels, forming a complete overhead seismic bracing system for fire pipelines.
