Application Scenarios
1.Fire Sprinkler System: No-drill beam connection for sprinkler pipeline lateral sway bracing on steel structure buildings.
2.MEP&HVAC Engineering: Seismic fixing adapter for water and ventilation pipeline where beam drilling is forbidden.
3.Steel Structure Construction: Quick seismic connection fitting for factory and commercial steel frame projects.
Step-by-Step Installation Guide
1.Cover UTT1101 onto steel beam flange and make flange closely fit inner jaw surface.
2.Pre-tighten set screws by hand, then uniformly fasten until screw hex heads break off.
3.Fix matched UTT series structural attachment with supporting bolt and ensure bolt fully seated.
4.Link bracing pipe and pipe clamp to finish complete sway brace assembly.
5.Check overall connection tightness before pipeline hydraulic pressure test.
Industry Compliance
1.Follow NFPA13 standard for fire protection seismic bracing installation rules.
2.Electro-galvanized coating meets international anti-corrosion industry standards.
3.All finished goods pass factory dimension and load inspection before delivery.
