A tongue and groove flange is a type of flange connection used in piping systems, where the pipeline components are sealed with a flanged joint. Tongue and groove flanges are an alternative to the more common raised face or flat face flanges and are designed to provide a tight seal when bolted together.

Here's a description of the tongue and groove flange:

- **Tongue**: One flange end has a protruding rib (the tongue) that extends out from the face of the flange.
- **Groove**: The mating flange has a corresponding recess or groove cut into its face where the tongue fits into.
- **Seal**: When the two flanges are bolted together, the tongue fits snugly into the groove, creating a channel that can be sealed with a gasket, such as an O-ring or a spiral wound gasket.
- **Advantages**: Tongue and groove flanges can be beneficial in applications where alignment is critical or where there is a need to accommodate thermal expansion and contraction of the pipeline The groove helps to center the two flanges and the tongue provides some guidance for alignment.
- **Applications**: They are often used in applications where a high level of precision is required, such as in the chemical and process industries, where leakage of hazardous materials must be minimized.
