Electro-Galvanized Branch Line Restraint Connector

Overview

UTT1401 universal connector is multi-functional carbon steel seismic fitting designed to assemble with threaded rod for fire sprinkler and MEP pipeline bracing. It meets three core application demands: branch line restraint anchored onto bolt & beam clamp, pitched roof NFPA13 compliant installation, upper hanger accessory to eliminate extra seismic bracing, widely used for high-rise, commercial and industrial fire protection projects following NFPA13 specification.

Key Features

Core Function: 3-in-1 usage for branch restraint, sloped roof mounting & upper hanger connection to omit extra seismic brace Matching Part: Matched with all standard size threaded rod for suspension assembly Raw Material: High-strength carbon steel Surface Finish: Electro-galvanized anti-corrosion coating Code Compliance: Strictly conforms to NFPA13 (2002) Sec 9.1.2.5 sloped roof requirements Application Flexibility: Compatible with anchor bolt, beam clamp and short hang rod for diversified site construction

Product Parameter Table

Application Scenarios

1. Fire Protection Sprinkler Systems

   Branch line sway restraint fixed with anchor bolt or beam clamp to limit branch pipe displacement under seismic load, fully compliant with NFPA13 fire codes.

2. Pitched & Sloped Roof Projects

   Specially designed sloped roof installation to satisfy NFPA13 section requirements for inclined ceiling sprinkler pipeline bracing.

3. MEP Suspension Pipeline Works

   Used as upper hanger connector with short rod to cancel redundant seismic bracing, save construction cost for HVAC and plumbing hanging systems.

1. Fasten UTT1401 onto building beam clamp or anchor bolt according to site construction layout.

2. Screw standard threaded rod into the connector for vertical or inclined pipeline suspension.

3. Select installation mode: branch restraint / sloped roof setup / upper hanger based on NFPA13 requirements.

4. Link threaded rod bottom end with matched pipe hanger or pipeline fittings tightly.

5. Check overall connection stability to confirm no extra seismic brace needed for upper suspension part.

Industry Certifications

1. Designed in full compliance with NFPA13(2002) Section 9.1.2.5 sloped roof seismic specifications

2. Electro-galvanized surface meets ASTM B633 international anti-rust coating standard

3. Raw carbon steel passes factory tensile strength test for seismic load bearing requirement

4. Every finished piece gets dimensional & surface inspection before delivery.

Core Product Advantages

Triple Multi-scene Application

One fitting realizes branch restraint, sloped roof mounting and upper hanger three usages to reduce spare part stock cost.
