Pipe Elbows: Pipe elbows help change the direction of the pipe’s flow. They come in 90-degree and 45-degree angles, and there are two types: long radius (which is smoother) and short radius (which takes up less space but causes more pressure).

Pipe Bend: Pipe bends are like gentle curves in the pipe. They’re used when you need a smooth change in direction to avoid pressure build-up. They come in different sizes, like 3D and 5D, which refer to the curve’s length.

Pipe Tee: A pipe tee looks like the letter “T” and is used to split the flow of fluid from the main pipeline. There are different types, like straight tees (which have the same diameter), reducing tees (which have smaller branches), barred tees (used in special pipelines), and wye tees (which connect pipes at a 45-degree angle to reduce friction).

Cross: A cross looks like a plus sign and has one inlet and three outlets. It’s mainly used in fire sprinkler systems, not regular plumbing.

Pipe Reducers: Pipe reducers make a pipe narrower. There are two types: concentric and eccentric. Concentric ones keep the middle of the pipe at the same height. They’re used when two different pipe sizes need to be the same in the middle of a system. Eccentric ones help keep the bottom of the pipe at a certain level, so the outside surface of the pipe stays level.

Pipe Caps: At the end of a plumbing system, there’s a cap. It covers the end of the pipe to stop leaks.

Stub Ends: Stub ends do the same thing as pipe caps but are used with lap joint flanges.

Piping Unions: These are used for pipes with low pressure that need to be taken apart often. They have three parts: a female end, a male end, and a nut. The nut, along with the female and male ends, creates a strong seal.

Pipe Coupling: There are three types: full, half, and reducing. Full couplings connect small pipes. Half couplings connect a small pipe to a large one. Reducing couplings connect two pipes of different sizes.

Selecting the right fittings for polyethylene (PE) pipes is crucial for ensuring a reliable and efficient piping system. Whether it’s compression fittings, electrofusion fittings, or other types mentioned above, each serves a specific purpose based on the application and installation requirements.
