UTT20 Pipe Clamp is a core certified seismic fitting to fasten fire sprinkler & MEP pipelines for anti-sway and seismic restraint. It matches Sch10, Sch40, GB/T3091, JIS G3454 standard pipes and works together with seismic attachments & brace tubes to form full NFPA13 compliant bracing assemblies, widely deployed across commercial, industrial and critical construction projects.
Core Function: Clamp pipeline for lateral seismic restraint & anti-sway protection
Size Range: Fits nominal pipe size from 2” up to 8”
Pipe Compatibility: Sch10, Sch40, GB/T3091, JIS G3454 standard steel pipe
Raw Material: High strength carbon steel
Surface Finish: Electro-galvanized coating for anti-corrosion
Certifications: UL, FM, CE listed, conform to NFPA13 & IBC/ASCE7
Install Spec: Fasten bolt at 100~115N·m torque with mark exposure check
