A pipe hanger looks like a simple bracket, yet its type decides whether the system sags, rattles, or fails. Choosing the right support matters as much as choosing the pipe itself, because each hanger type handles a specific load direction and installation condition. In fact, most piping problems trace back to mismatched hardware rather than defective pipes. This guide explains the four main types of pipe hangers—clevis, swivel, riser clamps, and beam clamps—and shows you when to choose each one.
The Four Main Types of Pipe Hangers
The pipe hanger family covers every support scenario, and four types handle the vast majority of installations:
- Clevis hanger: A U-shaped yoke with a threaded rod connection that cradles horizontal pipes. It distributes the load evenly across the pipe’s circumference and allows fine vertical adjustment.
- Swivel hanger: A pivoting design that self-aligns with the pipe, which makes it ideal for sloped runs, vibration-prone lines, and tight clearances.
- Riser clamp: A rigid two-piece clamp that grips vertical pipes and transfers their weight to the structure, which proves essential for tall risers.
- Beam clamp: A bolted attachment that connects hangers or rods to structural steel without welding or drilling.
Each type earns its place through a different strength, and the sections below explain when each one wins. For the full range of certified hardware, browse the pipe hanger product category.
Clevis Hangers: The Workhorse for Horizontal Pipes
Clevis hangers dominate commercial and industrial piping because they combine simplicity with versatility. The yoke cradles the pipe from below, the threaded rod carries the load to the structure, and the adjustment nut fine-tunes the elevation. In practice, clevis hangers suit chilled water lines, steam condensate, and sprinkler mains alike, and their open design simplifies installation on existing pipe runs. The FM&UL UTT30 clevis hanger exemplifies this design, with a forged yoke that resists deformation under load and a finish that survives humid mechanical rooms.
Swivel Hangers: Self-Alignment for Sloped and Moving Lines
Swivel hangers solve a problem that fixed yokes cannot: pipe movement. Because the hanger head rotates freely, it keeps the pipe centered even when thermal expansion or vibration shifts the run. Consequently, swivel hangers excel on sloped drainage lines, pump discharge piping, and any run where alignment changes during operation. They also simplify installation, since the installer can bolt the hanger first and let the head align itself with the pipe afterward. The FM&UL UTT40 swivel hanger and the UTT41 C-swivel hanger offer this pivoting action in different capacity ranges, so you can match the hanger to the line size.
Riser Clamps: Supporting Vertical Pipes
Vertical pipes carry their entire weight through a single point, which demands a hanger that grips rather than cradles. Riser clamps wrap around the pipe, transfer the weight to the structure, and allow minor vertical movement during thermal cycling. Fire protection systems rely on riser clamps heavily, since sprinkler risers run floor after floor and any slippage would wreck the alignment. The FM&UL UTT50 riser clamp handles this duty with a bolted two-piece design, and the China riser clamp series serves fire-fighting applications across commercial buildings and industrial plants.
Beam Clamps: Welding-Free Structural Connections
Beam clamps attach support systems to structural steel quickly and without hot work. This feature matters on occupied buildings, retrofit projects, and sites where welding permits add weeks of delay. In addition, beam clamps allow repositioning later, because installers can slide or unbolt them when the layout changes. The FM&UL BC1, BC2, and BC3 beam clamps cover light to heavy flange applications, which lets you standardize one family across a project.
Clevis vs. Swivel: How to Choose
Contractors often ask whether a clevis or swivel hanger fits their run, and the answer comes down to movement. If the pipe stays straight and level, a clevis hanger offers maximum rigidity and simpler adjustment. If the pipe slopes, vibrates, or expands, a swivel hanger keeps the load centered through the motion. Meanwhile, both types accept threaded rods, which means you can switch between them without redesigning the support layout. In short, choose clevis for stability and swivel for movement.
Riser Clamp vs. Beam Clamp: Vertical Support vs. Structural Attachment
Similarly, riser clamps and beam clamps answer different questions. A riser clamp supports the pipe itself; a beam clamp anchors the support system to the building. In practice, many assemblies combine them: a beam clamp holds the rod, and a riser clamp grips the pipe. Understanding this layering prevents the classic mistake of using a beam clamp as a pipe support, which leaves the pipe free to sag or slide.
How to Choose the Right Type of Pipe Hanger
Follow a simple sequence when you select hangers for a new system:
- Identify the pipe direction: Horizontal runs need clevis or swivel hangers; vertical runs need riser clamps.
- Check the load: Sum the pipe weight, media weight, and insulation, then verify the hanger’s rated capacity.
- Consider movement: Sloped, vibrating, or thermally expanding lines favor swivel hangers.
- Evaluate the structure: Existing steel allows beam clamps; new concrete requires anchors or embedded plates.
- Confirm code compliance: Standards such as MSS SP-58 define the material, design, and installation criteria for hangers, while NFPA 13 adds specific rules for fire protection piping. An ANSI overview of the latest MSS SP-58 edition summarizes the key requirements at a glance.
This sequence works for any project, and it eliminates the guesswork that leads to sagging pipes and failed inspections.

Frequently Asked Questions
1. When should I use a clevis hanger instead of a swivel hanger?
Choose a clevis hanger for straight, level runs that need rigid support and simple height adjustment. Choose a swivel hanger when the pipe slopes, vibrates, or moves with thermal expansion, because the pivoting head keeps the load centered.
2. Do riser clamps support the full weight of vertical pipes?
Yes. Riser clamps grip the pipe and transfer its entire weight to the structure, which prevents the pipe from sliding down through the floors. Codes specify the maximum spacing between riser clamps for each pipe size.
3. Can I use a beam clamp as a pipe support?
No, not directly. A beam clamp anchors a rod or hanger to the structural steel; the pipe support element still needs a clevis, swivel, or riser clamp. Using a beam clamp alone leaves the pipe unsupported.
4. Are all pipe hangers interchangeable across manufacturers?
No. Load ratings, material grades, and hole patterns vary by manufacturer. Always match components from the same certified family, and verify FM/UL listings where the project requires them.
Conclusion
The four types of pipe hangers each solve a distinct problem: clevis hangers carry horizontal loads, swivel hangers follow movement, riser clamps support vertical weight, and beam clamps attach to steel without welding. Therefore, when you plan a piping system, match each hanger to the pipe’s direction, load, and movement, then verify the hardware against MSS SP-58 and the applicable fire code.
