elbow—do you know

　　Elbows are categorized based on various design features as below:

　　Long Radius (LR) Elbows – radius is 1.5 times the pipe diameter

　　Short Radius (SR) Elbows – radius is 1.0 times the pipe diameter

　　90 Degree Elbow – where change in direction required is 90°

　　45 Degree Elbow – where change in direction required is 45°

　　A 90 degree elbow is also called a "90 bend" or "90 ell". It is a fitting which is bent in such a way to produce 90 degree change in the direction of flow in the pipe. It is used to change the direction in piping and is also sometimes called a "quarter bend". A 90 degree elbow attaches readily to plastic, copper, cast iron, steel and lead. It can also attach to rubber with stainless steel clamps. It is available in many materials like silicone, rubber compounds, galvanized steel, etc. The main application of an elbow (90 degree) is to connect hoses to valves, water pressure pumps, and deck drains. These elbows can be made from tough nylon material or NPT thread.
