API 6A Seal Ring Groove Gages (BX & R/RX)

Gagemaker-BX-gages-and-part

A ring groove is basically a closely dimensioned groove cut into the face of a pipe flange. Together with a gasket, a groove helps create a seal between parts, so it is important that a groove meets 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.

Face Groove and Hole Locations

Gagemaker’s face groove gages inspect groove diameters and groove widths. Excellent for inspecting hole locations. Additional extensions for various lengths are available, please contact customer service for more.

Parts and accessories can be found on our Ring Groove product page.

Gages ship with default T188(BX) or T072 (BXG) contact points, but can be substituted upon customer request. Please specify ring groove type and size when ordering.
