Hangers and Supports

-- Steady & Reliable Manufacturer --

Introduction: Structural Integrity for Sprinkler Piping

Hangers and Supports are vital, yet often overlooked, components that bear the static load of the fire sprinkler system (pipe, water, and fittings) and provide necessary bracing against dynamic forces, such as seismic events or water hammer. Proper selection and spacing are mandated by NFPA 13 to ensure the system remains intact and functional during a fire event.

Our inventory includes a full range of NFPA 13 compliant hangers: Clevis Hangers (most common, used for grooved and threaded pipe), Riser Clamps (for vertical pipes), Swivel Hangers (for pitched ceilings), and a variety of Beam Clamps and Structural Attachments (for securing piping to various building materials like concrete, steel, and wood). We also supply specialized Seismic Bracing components, including sway braces, cable restraints, and structural attachments required for installation in earthquake-prone zones.

All components are made from durable steel (carbon steel or galvanized), designed with appropriate load ratings, and meet the necessary UL and FM standards. They are engineered for easy adjustment and secure locking to streamline the installation process while ensuring the required safety margins are met. (Approx. 530 words)

Advantage: Load Certification, Code Compliance, and Adjustability

  • NFPA 13 Mandatory: Components are sized and tested to meet the exact load-bearing and spacing requirements mandated by NFPA 13, avoiding installation rejection.
  • UL/FM Load Rating: All hangers carry tested load certifications, ensuring they can safely support the static weight of the water-filled pipe with a high factor of safety.
  • Seismic Bracing Expertise: We provide full kits and individual components that simplify the engineering and installation of code-required sway bracing.
  • Adjustability: Clevis and swivel hangers allow vertical adjustment during installation to ensure proper slope and drainage of the pipework.
  • Corrosion Protection: Electro-galvanized or Hot-Dip Galvanized finishes extend the service life, especially in non-climate-controlled or high-humidity areas.
  • Ease of Installation: Designed with standard threading and simple bolt/nut mechanisms for quick and secure attachment to the building structure.

Structural Support and Seismic Protection

Commercial and Industrial Buildings

Clevis hangers and threaded rods are used to support horizontal pipe runs below the roof or ceiling structure, bearing the full weight of the water-filled system.

High-Rise Structures

Riser clamps are used to support vertical pipe risers at each floor level, carrying the load of the piping and water from the floors above.

Seismic Zones

Lateral and longitudinal sway bracing components are installed to limit pipe movement and prevent structural damage during an earthquake (NFPA 13 Section 18).

Pump Rooms and Risers

Heavy-duty clamps and attachments are used to counteract the dynamic forces (vibration and thrust) generated by the fire pump and rapid valve operation.

Areas with Vibration

Hangers with rubber inserts (e.g., isolation hangers) used near heavy machinery to dampen vibration and protect piping integrity.

Professional Usage Tips

  1. Spacing Verification:

    Confirm the hanger spacing does not exceed the NFPA 13 maximums (e.g., 15 feet for steel pipe) and is adjusted based on pipe size and material.

  2. Seismic Zone Requirement:

    In regions subject to seismic design categories, all required sway braces must be installed correctly, typically within 40 feet of the end of the pipe and at intermediate intervals.

  3. Structural Load:

    Ensure the building structure itself (beams, concrete slabs) can handle the combined load of the pipe, water, and hanging components.

  4. No Welding on Threaded Rods:

    Never weld threaded rods or hangers unless explicitly permitted and certified by the engineer, as welding severely compromises the rod's load strength.

  5. Riser Clamp Location:

    Riser clamps must be located at the base of the riser and at each intermediate floor level to properly transfer the vertical load to the structure.

FAQ

A Clevis Hanger is a loop-style hanger attached to a threaded rod, commonly used for supporting horizontal pipe runs and allowing for minor vertical adjustment.

Seismic Sway Bracing uses rigid steel members (struts) or cables to restrain the pipe from excessive lateral or longitudinal movement during an earthquake.

NFPA 13 limits the maximum spacing for 2 inch steel pipe to 15 feet (4.6 m).

Yes, we supply specialized plastic or coated metallic hangers designed for CPVC that meet the tighter spacing requirements (e.g., 5 feet to 6.5 feet) for plastic pipe.

Hot-Dip Galvanizing is a process where the steel is immersed in molten zinc, providing a thicker, more durable, and superior corrosion-resistant coating for outdoor/harsh environments.

Hangers and supports should be visually inspected quarterly or annually to ensure they are undamaged, securely fastened, and not overloaded (NFPA 25).

The Minimum Order Quantity (MOQ) for high-volume items like 1 inch and 2 inch clevis hangers is typically 5,000 units.

No, seismic bracing is only required in regions designated as Seismic Design Categories C, D, E, or F, as defined by ASCE 7 and NFPA 13.

All pipe sizes 2.5 inch and larger require bracing in seismic zones. Pipe 2 inch and smaller may require special restraint depending on its connection to the main line.

The load calculation includes the weight of the pipe itself plus the weight of the water filling the pipe volume, multiplied by the spacing interval.
