Overview
UTT42 adjustable band hanger without swivel nut is one-piece stamped pre-galvanized carbon steel pipe suspension component specially for non-insulated stationary sprinkler piping. Key reinforced part adopts double-layer steel plate design to improve load capacity; vertical height can be adjusted between 5/8 inch ~2 inch by matched threaded rod and two separate nuts (nuts sold separately). Lower nut fine-tunes pipeline mounting gradient, top lock nut prevents loosening caused by pipeline vibration, full specification covers DN20~DN200, widely applied in fire sprinkler, MEP plumbing and industrial fixed pipeline suspension projects.

Application Scenarios
1.Fire Sprinkler System: Standard suspension hanger for automatic fire non-insulated fixed sprinkler pipelines compliant with NFPA13 design requirements.
2.MEP & HVAC Engineering: Gravity support for bare cold/hot water pipeline in high-rise, shopping mall and commercial buildings.
3.Industrial Construction: Fixed suspension accessory for factory process non-insulated piping layout.
Step-by-Step Installation Guide
1.Fix M10/M12/M16 standard threaded rod onto ceiling anchor or upper channel steel in advance.
2.Wrap integrated UTT42 band tightly around outer wall of target bare pipeline.
3.Screw two separate matching nuts onto suspension threaded rod, hang UTT42 hanger onto the middle of double nuts.
4.Rotate lower nut to adjust pipeline mounting gradient and vertical height within 5/8"~2" adjustable range.
5.Tight top lock nut firmly after dimension confirmation to avoid vibration loosening and complete installation.
Industry Compliance
1.Conforms to MSS SP-58/SP-69 international pipe hanger manufacturing specifications & NFPA13 fire protection installation standard.
2.Pre-galvanized surface meets ASTM anti-corrosion coating industry criteria.
3.All finished products pass factory dimensional inspection and graded load sampling test before delivery.
Core Product Advantages
Double-Layer Thickened Load-Bearing Design
Key stressed area with double steel thickness for higher structural strength and stable long-term load bearing.
Large Range Vertical Adjustable Height
5/8''~2'' adjustment space easily offsets on-site construction elevation errors and pipeline gradient needs.
Non-Swivel Compact Structure
No built-in swivel nut simplifies product structure, reduces cost; customer selects matching nuts separately per demand.
Graded Load & Complete Size Coverage
From DN20 small pipe to DN200 large pipe with graded rated load to satisfy different pipeline weight demands.
Pre-Galvanized Whole Body
Integral pre-galvanization avoids partial rusting, good corrosion resistance for conventional indoor construction environment.
Full UTT Series Matching
Perfectly compatible with UTT threaded rod, beam adapters and pipe clamps for integrated suspension bracing system.
