Pit Depth

The PD-3000 series of gages inspect the depth of surface pitting on tubular goods. The gage also accepts other types and sizes of contact points for use in other applications, such as groove and thread depth inspection. Select the PD-3000 gage model based on the type of indicator required.

For buttress connections to be compliant under the 16th edition of the API 5B, thread run-out inspection is required.

When inspecting buttress run-out with a Gagemaker BR-2001, inspectors often question where to place the contact point on the thread. Now, the new API 5B Section 5.3.3.4 specifies the location of the inspection point.

When the thread path terminates/vanishes after the triangle make-up stamp, place the contact point at the apex of the triangle.

When the thread path terminates before or within the triangle make-up stamp, place the contact at the thread’s termination point.
