Step-by-Step Installation Guide
Clamp UTT12B base firmly onto flange of building I-beam with M12 bolt.
Adjust hinge angle according to actual bracing pipe direction on site.
Fix one end of seismic brace pipe onto hinge’s secondary mounting hole.
Lock all fasteners tightly and inspect connection firmness.
Final stability check before pipeline hydraulic pressure test.

Core Product Advantages
Special I-beam Clamping Base
No pre-drilling needed on steel beam, directly clamp on beam flange to save construction cost and working hours.
Multi-angle Adjustable Structure
Flexible angle adjustment adapts various irregular layout of on-site bracing pipes.
Multiple Anti-rust Surface Choices
Four surface options match indoor, humid and slightly corrosive construction environments.
Higher Rated Load Capacity
7800N bearing capacity superior than regular wall hinge, stable for heavy-load pipeline bracing.
Full System Compatibility
Perfectly match all UTT series pipe clamps, seismic attachments and bracing accessories.
