Pipe fittings are connectors used to join different sections of pipes, change their size, redirect the flow, or connect pipes to equipment. These fittings come in various types to serve specific purposes.
Pipe fittings can be made from different materials depending on the application. Common materials used for fittings include rubber, copper, steel, and plastic. For sewer applications, PVC (polyvinyl chloride) fittings designed specifically for drain, waste, and vent purposes are commonly used. These fittings are often referred to as DWV fittings. PVC fittings can be found in various colors such as white, gray, green, blue, and yellow. However, the colors themselves do not have specific meanings. White and gray are frequently used in plumbing applications, while green is often associated with sewage systems.
There are several advantages to using pipe fittings. They are lightweight, which makes them easy to transport and install. Additionally, they are flameproof and provide electrical insulation. Fittings also resist shocks caused by earthquakes or external pressures. Moreover, they can withstand corrosive substances and solvents, making them suitable for various environments and applications.
