What are riser clamps used for?
What are riser clamps used for?
Riser clamps are a two point load bearing component and are usually used for vertical running pipe lines wherein shear lugs are welded to the pipe, the riser clamp top surface contacts the shear lug, and the load is transferred through the legs of the clamps to the support component such as a rigid rod, spring, etc.
How does a riser clamp work?
A Riser clamp is a type of hardware used by mechanical building trades for pipe support in vertical runs of piping (risers) at each floor level. The friction between the pipe and riser clamp transfers the weight of the pipe through the riser clamp to the building structure.
How to install riser clamp?
Riser clamp installation—the clamp is fastened to the structure. Riser clamps transfer the load of riser pipe to the building by interfacing with a structural member. Often, this is done by letting the riser clamp sit on the edges of a slab penetration. In effect, the hole in the slab acts as the hanger for the pipe.
What is a friction clamp?
: a clamp that holds or supports by friction alone without indentation or deformation of the bodies concerned.
What is a clevis hanger used for?
Clevis hangers are pipe supports that are designed to secure hanging or elevated pipe runs. If you need to suspend piping from elevated beams or the ceiling, clevis hangers are a lifesaver. Generally, clevis hangers include a yoke that connects to your support overhead.
What is a strut clamp?
Strut clamps are used to secure vertical or horizontal pipe runs to standard strut channel. Various options are available for copper, black, cast iron, PVC and ABS pipes.
What is Mech riser?
A vertical riser is any component that extends vertically through a building, including for example stairs and lifts, but the term is most commonly used to refer to ductwork, pipes, conduits and cables. Other types of vertical riser include: Dry riser: Used to supply water within buildings for fire-fighting purposes.
What is a pipe riser?
A riser pipe is a durable metal or plastic pipe which extends from the water supply line to the water heater and up through the walls to deliver water, steam, or gas to the lavatories, kitchens, and plumbing fixtures on the upper floors of a building and branch to up to two higher levels.
What is a riser support?
Vertical pipe riser supports, anchors, and guides isolate the pipe from the structure to minimize noise and vibration transmission, while also allowing the pipe to expand and contract with minimal change in the support forces.
How much weight can a clevis hanger hold?
Fig. 83: Adjustable Clevis Hanger
| PIPE SIZE | MAX. RECOM. LOAD, lbs. | E |
|---|---|---|
| 12 | 3800 | 10 3/16 |
| 14 | 4200 | 10 13/16 |
| 16 | 4600 | 12 7/16 |
| 18 | 4800 | 13 15/16 |
How does a clevis hanger work?
A clevis hanger has a swivel yoke at the top supported by an adjustable vertical rod. It has two clevises, one V-shaped and the other U shaped. The V-shaped clevis is attached to the ceiling and the U-shaped clevis is used to hold the pipe securely in its place.
What are strut channels used for?
Strut channel is used to mount, brace, support, and connect lightweight structural loads in building construction. These include pipes, electrical and data wire, mechanical systems such as ventilation, air conditioning, and other mechanical systems.
What do riser clamps do for insulated pipes?
Riser Clamps for Insulated Pipe Use these clamps to route insulated pipe through floors. They have a plastic insert that creates a seal around the pipe’s insulation to prevent the pipe from sweating, which can cause mold and corrosion. All are zinc-plated steel for good corrosion resistance.
How many rows of riser clamps are there?

Where do the clamps go on a fire sprinkler system?
Riser clamps normally rest on top of penetrations in a structural member so that the weight of the riser is transferred to the structure. However, sometimes they are needed below the structural penetration —not to hold weight, but to prevent upward movement permitted by flexible couplings. NFPA 13 says the following:
What kind of clamps to use on vertical drain pipe?
Clamps secure vertical pipe in sanitation drain applications and prevent them from coming in contact with the mounting surface. 304 stainless steel clamps have very good corrosion resistance. For technical drawings and 3-D models, click on a part number. Lg. Lg.
