Pipe fittings come in various shapes and sizes and are used to connect, redirect, or control the flow of fluids in plumbing and industrial systems. Here are some commonly used pipe fitting dimensions:

Pipe Schedule: Pipe fittings are also associated with a pipe schedule, which defines the wall thickness of the pipe. The most common schedules are Schedule 40 and Schedule 80, but there are other schedules available for specific applications.

Dimensions: Pipe fittings have different dimensions depending on their type. Here are some examples:

  • Elbows: Elbows are used to change the direction of the pipe. They come in different angles, such as 45 degrees and 90 degrees. The dimensions of elbows include the outside diameter (OD), center-to-face (C-to-F) distance, and wall thickness.

  • Tees: Tees are used to create branch connections in a pipe system. The dimensions of the tees include the OD, C-to-F distance, and wall thickness. They may also have equal or unequal branch sizes.
  • Reducers: Reducers are used to connect pipes of different sizes. The dimensions of reducers include the OD and length of both ends.
  • Couplings: Couplings are used to connect two pipes together. The dimensions of couplings include the OD and length.
  • Flanges: Flanges are used for connecting pipes, valves, or other fittings. The dimensions of flanges include the OD, bolt hole diameter, and bolt circle diameter.

It's important to note that the specific dimensions of pipe fittings may vary depending on the standard being followed (e.g., ANSI, ASME, DIN) and the material of the pipe (e.g., steel, copper, PVC). It's always recommended to refer to relevant standards and specifications or consult with a professional for accurate and specific pipe fitting dimensions for your application.
