TYPES OF PIPE FITTINGS USED IN CONSTRUCTION

WHAT ARE PIPE FITTINGS USED FOR?

Pipe fittings, also known as pipe connectors, attach one pipe to another in order to lengthen the run or change the flow direction in a plumbing system. These are used to combine, divert or reduce the flow of the water supply, and they come in a variety of sizes to fit the pipe they will connect.

.

PURPOSE OF A PIPE FITTING:

The basic purposes of any pipe fitting is as follows:

Connecting the bores of two or more pipes or tubes.

Connecting pipe sections.

Connecting a pipe to a different apparatus.

Changing the direction of fluid/liquid flow.

Maintaining or regulating the flow.

Closing and sealing a pipe.

TYPES OF PIPE FITTINGS IN PLUMBING SYSTEM

ELBOWS: 

Pipe fittings are a very important pipe fitting. When we discuss about a pipe elbow, it means a pipe length with a closed curve

A pipe elbow is an accessory installed between two sections of pipe or tube that allows a change of direction, generally in the 90 ° or 45 ° direction.

Available in: Acrylonitrile Butadiene Styrene (ABS plastic), polyvinyl chloride (PVC), chrome-plated brass, chlorinated polyvinyl chloride (CPVC), stainless steel, malleable (galvanized and black), and copper.

ELBOW

 TEE

Pipe Tee is a type of T-shaped pipe fitting that has two outlets, 90 ° from the connection to the mainline. It is a short tube with a side outlet. Pipe Tee is used to connect pipes with a pipe at a right angle to the line.

Pipe Tees are widely used as plumbing fixtures. Tee pipes are widely used in pipeline networks to transport two-phase Water mixtures.

Available in: ABS, copper, CPVC, PVC, brass, chrome-plated brass, malleable (galvanized and black), and stainless steel.

TEE

REDUCER

This pipe fitting is used to reduce the flow size of the pipe from the bigger to smaller ones

.

There are two kinds of reducers-

Concentric Reducer

&

Eccentric Reducer.

Its is a cone-shaped fitting used for gradual pipe reduction. The latter has one side facing the mouth of the connecting pipe which reduces the possibility of airflow.

Available in: ABS, copper, CPVC, PVC, brass, chrome-plated brass, malleable (galvanized and black), and stainless steel.

REDUCER

CROSS

This type of pipe installation consists of four openings in all four directions. This assembly is adjacent to the four-pipe meeting at the same point. There is one inlet and three outlets to drain water or other fluids in four different directions. These types of pipe fittings are commonly used in fire sprinkler systems.

Available in: PVC, brass, malleable (galvanized and black), and stainless steel

CROSS

COUPLINGS

Pipe couplings are accessories that help extend or finish pipe runs. These accessories are also used to change the size of the pipe. The couplings extend a path joining two sections of pipe. They are known as reduced coupling if they are used to connect pipes of different sizes.


Couplings are also known as repair couplings. These couplings have no stops or splines and can be attached anywhere along the length of the pipe to prevent leakage of any kind.

Types of Couplings:

Couplings are an integral part of pipe fittings and are of various types like:

Full Coupling

Half Coupling

Reducing Coupling

Available in: ABS, brass, copper, chrome-plated brass, CPVC, PVC, malleable (galvanized and black), and stainless steel.

COUPLING

UNION

Pipe Union is a type of connection equipment designed to join two pipes that can be separated without causing any deformation in the pipes.


With the help of the pipe joint, all kinds of small diameter pipe connections are made that require a positive seal and easy assembly as well as disassembly.

Available in: Brass, copper, chrome-plated brass, malleable (galvanized and black), PVC, CPVC, and stainless steel.

Three parts of pipe union:

A nut

A female end

A male end

UNION

NIPPLE

The nipple is a short piece of pipe that has a male thread at each end or at one end. It is used to connect two other accessories. Nipples are used to connect pipes, hoses, and valves. Pipe nipples are used in low-pressure pipes.

Available in: Brass, chrome-plated brass, malleable (galvanized and black), PVC, copper, and stainless steel.

NIPPLE

.

ADAPTORS

If the pipes are not having special ends or plain ends then adaptors make them threaded either

Male Or Female

Whatever is needed. Male adapters contain male thread and female adapters contain female thread. One end of the adapter is smooth and is glued, welded, or welded to the end of the smooth tube.

Available in: ABS, CPVC, copper, malleable (galvanized and black), PVC, brass, and stainless steel.

PIPE BEND

Long radius pipe bends are used in the fluid conveying line that requires pigging. Due to its long radius and smooth change of direction, the pipe bend has a very small pressure drop and smooth fluid and pig flow are possible.

1.5D, 3D and 5D Pipe bends are commonly available. Here, D is the pipe size.

BEND

TRAP

The plumbing trap is part of the drainage system. It is developed or designed in such a way that it retains a small amount of wastewater from the discharge, from the accessory to which it is connected, as a barrier to prevent contaminating gases or air from entering the building.

WYES

A standard WYE is a Y-shaped fitting that allows a pipe to join each other at a 45-degree angle. The wyes are similar to the shirts, except for the angle of the branch to reduce friction and turbulence. They are commonly used to join a vertical drainpipe to a horizontal one.

Available in: Brass, ABS, and PVC

WYES

FLANGE

A flange is a method of connecting pipes, valves, pumps, and other equipment to form a pipe system.

It also provides easy access for cleaning, inspection or modification. The flanges are usually welded or bolted. Flanged joints are made by screwing two flanges with one joint between them to provide a seal.

Available in: Brass, copper, malleable (galvanized and black), and PVC.

FLANGE

CAPS & PLUGS

Both pipe fittings are used to close pipe ends, caps, and plugs, either temporarily or permanently. Plugs are placed inside the pipe and are screwed to hold the pipe for future use.

There are a good number of ways a cap can be applied to the pipe, such as welding, glue, or threading, depending on the pipe material

PLUGS & CAPTIONS

VALVES

Valves are primarily used to regulate or stop the flow of fluid in a pipeline. There are several types of valves, such as throttling, non-return, and isolation. Check valves only allow the liquid to flow in one direction and are often found in drains. Also called check valves.

VALVES

BARB

Barb is another useful pipe installation used in pipe systems that connects flexible pipes to pipes. It has a male-threaded end on one side that connects to the female thread, and the other end has a single or multiple barbed tubes inserted into the flexible tube.

Available in: Brass for hot water uses and plastic for cold water
