Galvanized Dual-Hole Adjustable Seismic Hinge

Overview

UTT12D dual-hole adjustable seismic hinge is carbon steel anti-seismic connector featured with double mounting hole layout, designed for lateral and longitudinal pipeline bracing on wall or steel beam. Adjustable hinge angle optimizes field installation efficiency, four optional anti-corrosion surface finishes, widely used in fire sprinkler, HVAC and MEP pipeline seismic fixed projects of commercial & industrial buildings.

Key Features

Core Function: Dual-hole structure connects building wall/steel beam and bracing pipe for lateral & longitudinal seismic sway restraintRaw Material: High-strength carbon steelMount Hole: Φ14mm, compatible with M12 expansion boltMax Rated Load:7300NAvailable Surface: Electro-galvanized, HDG, DACROMET, epoxy sprayingUnique Advantage: Double-hole design improves installation stability under heavy seismic load

Application Scenarios

1. Fire Protection Sprinkler System: Dual-hole fixed seismic bracing for large-diameter sprinkler pipeline requiring higher installation stability.

2. MEP & HVAC Engineering: Anti-seismic support for heavy-duty water pipe and ventilation duct on wall or steel beam.

3. Industrial Construction: Seismic connecting component for factory pipeline with high seismic load requirement.

Step-by-Step Installation Guide

1. Secure UTT12D onto wall or steel beam with M12 bolts via dual reserved holes for reinforced fixing.

2. Adjust hinge angle according to actual bracing pipe layout on construction site.

3. Fasten one end of seismic brace pipe to hinge connecting hole and fully lock all fasteners.

4. Check overall connection tightness and stability before pipeline hydraulic pressure test.

Industry Certifications

1. Conforms to NFPA13, IBC, ASCE7 North American seismic design specifications

2. All galvanized surface complies with international ASTM anti-corrosion coating standard

3. Each production batch passes factory load test and dimensional inspection
