Question: What Is A Swing Joint

A swing joint is a pipe joint designed with a series of two to five 90-degree elbows and nipples so that the parts joined are movable and can be rotated relative to the other.

What is the purpose of a swing joint?

SWING JOINT ALLOWS FOR RISER MOVEMENT STRESS CREATED BY UP AND DOWN MOVEMENT OF RISER, CAUSED BY FROST HEAVING OR GROUND SETTLING, IS RELIEVED BY THE ELBOWS TURNING SLIGHTLY AT PIVOT POINTS.

What is a swing elbow in piping?

A technique for providing flexibility at various points in an underground piping system by making up joints composed of steel 90-degree elbows and nipples. A swing joint is made up of a series of from two to five 90-degree pipe elbows and nipples (short pieces of pipe, threaded on each end).

What is a street l?

A street elbow (sometimes called a street ell or service ell) is a type of plumbing or piping fitting intended to join a piece of pipe and another fitting at an angle. Instead, a street elbow has a female fitting on one end and a male fitting on the other.

What is an articulated riser?

Articulated risers are basically a riser with one M&F elbow on one end and two M&F elbows on the other. These elbows are pivot points, which allow for the pop-up sprinkler position to be adjusted. Larger sprinklers like the 150mm and 300mm pop-ups that have a side inlet, require even less trenching.

Why is a street 90 called a street 90?

when water mains were being run down a street, the installers would put a tee in front of a house. the branch of the tee was facing up. into the branch they would put an elbow with male threads on one end and female threads on the other. so it was known as a “street” elbow.

What is tee plumbing?

A tee, the most common pipe fitting, is used to combine or divide fluid flow. Tees can connect pipes of different diameters or change the direction of a pipe run, or both. Available in a variety of materials, sizes and finishes, they may also be used to transport two-fluid mixtures.

What is a sweep elbow?

A sweep elbow is simply an elbow made out of a bent piece of pipe. To put this into context versus weld elbows, a short radius sweep elbow has a centerline of 3D (3 x the diameter of the elbow) whereas that is considered a long radius on a weld elbow. Sweep elbows usually have tangents on each end as well.

What is a bell reducer?

Bell Reducers for Sale at Compressed Air Systems Bell reducers, or reducing couplings, are used to extend a run of pipe by joining two sections with different diameters. Compressed Air Systems specializes in everything related to compressors, so we can help you find much more than the right bell reducers.

What is PVC elbow?

PVC elbow is designed to turn the flow of a liquid. This allows for the configuration of a piping system to fit in an existing location. Often in home plumbing, for example, the plumbing needs to turn to flow where it is needed to avoid existing structures in the home or access outside lines.

What is a copper street elbow used for?

These wrought (wrot) copper street elbows are used to connect a copper pipe to a copper fitting at a 90-degree angle. Manufactured to ASTM and ANSI standards from commercial grade C12200 alloy used by leading copper pipe fitting manufacturers such Nibco and Mueller.

How do you get rid of cracked PVC elbow?

Open the jaws on a pipe cutter, and insert them around one edge of the PVC elbow joint where it connects to another PVC pipe. Squeeze the handles of the cutter together firmly to cut all the way through the pipe. Repeat the process on the other end of the PVC elbow joint to detach it completely.

Do you need Teflon tape on sprinkler risers?

Standard Teflon tape or plastic compatible Teflon sealant around the riser or swing joint threads is all that is required to prevent leaks around the inlet threads of Hunter sprinklers. The Teflon also provides a long-lasting lubricant should it become necessary to remove the sprinkler for servicing.

What is a sprinkler riser for?

It is where above ground vertical supply pipes (system risers) connect the water supply to the fire sprinkler system’s cross and/or feed mains and where the system’s pressure and water are monitored and controlled.

What is a copper elbow?

Copper is a highly versatile material that’s well-suited to pipes that carry either gas or liquid such as water. They’re corrosion-resistant, largely maintenance-free and long-lasting, and they can be purchased in a range of sizes and diameters.

What does no hub mean in plumbing?

Intended for use with DWV systems, no-hub couplings are used to join cast iron soil pipe that does not have the traditional Hub and Spigot. They are normally installed using a torque wrench. Generally, they have more clamps and provide a greater band load than standard no-hub couplings.
