Each fitting in the pipe parts catalog includes one or more connector engagement length (CELn) values. CEL is the length of pipe that is inserted into a fitting connection. CEL values are based on industry standards and are configured for all pipe fittings.
Except for couplings, pipe connectors are located on the ends of pipe segments and fittings. In a drawing, the software depicts a pipe that is connected to a fitting as attached to the end of the fitting. However, in an actual pipeline, the pipe is inserted into the fitting.
