Plastic pipe fittings are essential components in the construction and maintenance of piping systems. They connect different sections of plastic pipes， ensuring that fluids can flow smoothly through the system. Here are some key types of plastic pipe fittings: 1. Elbows : Elbows are used to change the direction of the pipe. They come in various angles， such as 45 degrees， 90 degrees， and 180 degrees. 2. Tees : Tees are used to connect three pipes at a single point. They can be straight or angled， depending on the specific application. 3. Reducers : Reducers reduce the diameter of one pipe to fit another. They are commonly used in systems where the flow rate needs to be adjusted or where space is limited. 4. Valves: There are various types of valves， including ball valves， gate valves， check valves. 5. Flanges : Flanges are used to connect pipes to other equipment or structures.
