Types of Pipe Fittings
 

Elbows
Elbow pipe fittings are relied on to alter the flow direction between two pipes. These fittings are essential as pipes are built with straight lines, so elbows allow for all the various straight pipes to connect. Typically, this fitting comes in 90, 45, and, occasionally, 22.5-degree angles and is screwed or glued into place.


Couplings
Ideal for preventing leakage in pipes, couplings are pipe coverings used for pipes that have the same diameter or that have been damaged or split. When it comes to coupling, there are two types of pipe fittings typically used in plumbing - compression coupling and slip coupling.


Union Pipe Fitting
Similar to a coupling fitting, unions are used to connect pipes - typically those that are made with different materials. This fitting appears as a small nut. However, unlike a coupling, unions can be easily removed whenever needed.


Adaptors
To help make a pipe threaded as either male or female, adaptor fittings are used. For male adapters, there are male threads, while female adapters have female threads. This is for when pipes have plain or don't have special ends, adapting them to the needs of the surrounding system.

Grooved Pipe Fittings

Bushings
To fit larger and smaller pipes with a link, Bushings fittings are relied on to connect sizes together. Typically taking up less room than a union or coupling, Bushings are sometimes inside-out threaded, although they are used for the same purpose as their union/coupling counterparts.


Flanges
Flanges are pipe fittings that work to connect together pipes, valves, flanges engines, and other sections for a full, well-running network. These fittings typically feature collars, ribs, rims, or edges that are flush to surfaces and are joined using clamps, bolts, threading, welding, or brazing.


Tees and Crosses
When a pipe fitting has more than one opening, it's either a tee or across. With tees, there are three openings, with one inlet and two outlets This is ideal to merge the flow of two inlets with one outlet. On the other hand, crosses have four openings in four different directions.


Caps and Plugs
To simply differentiate between the two, a cap doesn't have threading while a plug does. A cap is best for stopping low-pressure water, while when pressure is high, a plug is utilized for a tighter, secure screw. Often, plugs are so secure that they require special equipment to remove, while caps need to be soldered or glued into place.

 

Surface Treatment of Pipe Fittings
 

Anti-corrosion coating

Applying a layer of anti-corrosion paint, spraying, or coating with materials such as zinc on the surface of the pipe fittings to prevent corrosion.

Galvanization

Steel pipe fittings are often hot-dip galvanized or electroplated to increase their corrosion resistance.

Sandblasting

Removing oxide layers, oil stains, and other contaminants from the surface of pipe fittings by sandblasting to make it cleaner and more conducive for subsequent coating.

 

Polishing

Polishing the surface of pipe fittings to improve smoothness and glossiness, enhancing the appearance.

Hardening treatment

Some special pipe fittings may undergo surface hardening treatment to enhance wear resistance.

Acid pickling

During production, pipe fittings are often acid pickled to make the surface smoother, free of oxide layers, and rust spots.

 

Pipe Fittings Material

 

Brass

Brass has optimal conductivity and high-temperature ductility, and additionally is a strong, durable metal that's corrosion-resistant. This is best for threaded and smaller compression fittings.

Aluminum

The preferred fitting for plumbing with aluminum piping, aluminum is corrosion-resistant and lightweight. This is ideal for high-corrosion resistance needs.

Copper Pipe Fittings

With improved conductibility and corrosion resistance, copper is often used for residential water supply lines. This is best used with copper piping and can come in both soft and rigid forms. Copper pipe fittings are also known for their ability to resist very high temperatures.

Cast Iron Fittings

Best for sanitary, storm drain, waste, and vent piping for building construction, both male iron pipe fittings and female iron pipe fittings are abrasion-resistant and very strong.

Steel

Great for high-heat situations, this durable and strong material is ideal for both commercial and industrial uses. It can carry water, as well as flammable gases.

Stainless Steel

With corrosion resistance due to its 10.5% chromium makeup, stainless steel is strong and great for sanitary applications or uses with aggressive materials.

 

Applications of Pipe Fittings
