Interface control document. An interface control document (ICD) in systems engineering and software engineering, provides a record of all interface information (such as drawings, diagrams, tables, and textual information) generated for a project.
How well do you know your pipe flanges? Remember that flanges come in a variety of shapes and sizes to suit different applications. A flange is usually in the shape of a disc and is used to connect two tubes together or to connect a pipe to a valve, tee, choke or other component. Providing support and strength, two flanges are typically attached to pipe ends with a gasket in between.
Flanges and Bolt Dimensions ASME/ANSI B16.5 - Class 150 to 2500. Diameters and bolt circles for standard ASME B16.5 flanges - 1/4 to 24 inches - Class 150 to 2500. Flange dimensions are determined by the pipe size and the pressure class required for the application. Flanges are standardized according publications from organizations like ASME, MSS, API and others.
