Face Groove and Hole Locations

Gagemaker’s face groove gages inspect groove diameters and groove widths.They are also ideal for inspecting hole locations. Additional extensions for various lengths are available.

A ring groove is basically a closely dimensioned groove cut into the face of a pipe flange. Combined with a gasket, the groove helps facilitate a seal between parts. It is critical that the grooves meet designated specifications.

API 6A ring grooves are divided into three ring types, BX, R, and RX. Each type has different configurations and is designated by the type and a number, i.e. BX 150, R 41, etc.

API mandates the inspection of ring grooves. The necessary dimensions of a groove are clearly specified in API 6A. To pass API requirements, these dimensions must be met. For BX Grooves, the groove’s major diameter and width are specified. For R and RX Grooves, API specifies the groove’s pitch diameter and width.
