1, the screw thread gauge model (14)

Detection of external thread with: P - 1, P -2, P - 3, P - 4, P - 5, and P -6, P - 7, P - 8

Detection of internal thread with: B - 1, B - 2, B - 3,B - 4, B - 5, and B - 6

2, the name of the thread gauge and use

Detection of sucker rod thread

P - 7 truncated teeth on the top of the external thread end proofreading plug gauge

This rules on behalf of the external thread to allow maximum diameter, is used to:

Proofread and its matching ring gauge ring gage P - 8 and the corresponding work

Ring gauge calibration work shoulder the end verticality

Testing wear matching ring gauge, shake test.

P - 8 male end ring gauge

The rules and the external thread end plug gauge P - 7 pairs. When used as a check gauge and can be used for arbitration in case of any dispute over the external thread inspection.

P - 5 truncated teeth shape external thread check end check gauge.

The rules on behalf of the external thread allowed minimum diameter, is used to:

Proofread and its matching ring gage P - 6 ring gauge and the corresponding work

Testing wear matching ring gauge, shake test.

P - 6 external thread end ring gauge

The rules and the external thread end plug gauge P - 5 pairs. When used as a check gauge and can be used for arbitration in case of any dispute over the external thread inspection.

Internal thread inspection sucker rod with:

B-1 rifled through the ring gauge (test ring gauge)

This gauge representative female allowed minimum diameter, is used to:

Inspection on the thread plug gauge B - 2 and the corresponding work within plug gauge,

Can also be used for inspection gauge shoulder end verticality

B - 2 internal thread end plug gauge

Threaded end plug gauge B - 2 for polished rod coupling and reducing coupling test, but you can't test 9 degrees taper.

This gauge with internal thread end ring gauge B - 1 pair. When used as a check gauge and can be used for arbitration in case of any dispute over the external thread inspection.

B - 3 internal thread taper ring gauge (check the cone ring gauge)

Internal thread taper ring, plug gauge B and B - 3-4 for polished rod coupling and reducing coupling, is not used for sucker rod coupling.

This gauge represent basic taper thread, can be used as a standard gauge, is used to determine and its matched plug gauge B - 4 and the corresponding work plug gauge the distance between the end face.

B - 4 internal taper thread plug gauge

Internal thread taper plug gauge and ring gauge B B - 4-3 for polished rod coupling and reducing coupling, is not used for sucker rod coupling.

B - 5 internal thread check end ring gauge (check ring gauge)

The rules on behalf of the internal thread allows the largest diameter. Used for testing the plug gauge of pairing with B - 6 and the corresponding work, plug gauge, sucker rod, the polished rod, and reducing coupling.

B - 6 threaded end plug gauge

The gauge with the internal thread check ring gauge B - 5 pairs. When used as a check gauge and can be used for arbitration in case of any dispute over the internal thread inspection.

Test of polished rod male connection with:

P - 1 truncated teeth on the top of the external thread on the proofreading plug gauge

This rules on behalf of the external thread to allow maximum diameter, is used to:

Proofreading and its matching ring gage P - 2 ring gauge and the corresponding work

Check work rules shoulder end verticality

Testing wear matching ring gauge, shake test.

P - 2 external thread end ring gauge

The gauge cannot be used to check the taper 9 degrees

The rules and the external thread plug gauge P - 1 pair. When used as a check gauge and can be used for external thread inspection disputed arbitration.

P - 3 outer taper thread plug gauge (check the cone plug gauge)

The basic taper rules on behalf of the external thread. It can be used as a standard plug gauge to determine the external thread taper and its matching

Ring gage P - 4 and the distance between the corresponding work rules face used as work rules with P (P - 4-4 check gauge contrast examination)

P - 4 external thread taper ring gauge

The rules and the external thread taper plug gage P - 3 pairs. When used as a check gauge and can be used for external thread inspection had a fight with the arbitration.

P - 5 truncated teeth shape external thread check end check gauge

The rules on behalf of the external thread allowed minimum diameter, is used to:

Proofread and its matching ring gage P - 6 ring gauge and the corresponding work

Testing wear matching ring gauge, shake test.

P - 6 external thread end ring gauge

The rules and the external thread end plug gauge P - 5 pairs. When used as a check gauge and can be used for external thread inspection disputed arbitration.
