API 7-2 SECOND EDITION JAN. 2017 PUBLISHED!
You have until June 6, 2017 to comply with the new American Petroleum Institute’s (API) 7-2 Inspection Specification for Rotary Shouldered Connections.
We’ve highlighted some key points below:
• Resolution of Indicators
Indicator resolution requirements have been updated for all lead, height, and taper gages. (API 7-2 7.4.1, 7.5.2, 7.6*) Now gages with alternate indicators may not meet the new API requirements and must be replaced. Here are the new inspection elements and their new required resolutions:
Element to Inspect
New Indicator Resolution
We highly recommend that you check your gages ASAP. To help, we’ve provided a table to help you determine the correct indicator for your gages. Please note we’ve provided two model numbers for the indicators in some instances as the models have changed over the years, but either is compliant. Most of our indicators have the model number on the indicator face. Also note that we’ve shown gages which we may not manufacture any longer but are still in the field.

*The 2056 indicator for the IT-6000 for metric threads requires a slight modification to fit the gage.
If you do find that you need replacements, please ask about our Trade-in Program or submit a Trade-in Request.
• New Bevel Diameters
Tables for connection bevel diameters have changed. (API 7-2 5.2.2)
• Drawings Require New Angles
All RSC box drawings now require a 30° max back-of-the-box angle. (API 7-2 6.3.3, Fig 10)
• New emphasis on the effects of lead error
The effects of lead error on standoff and pitch diameter can no longer be ignored. Greater emphasis has been placed on mandatory lead inspection. (API 7-2 7.2.1)
• Gap on Hand-tight Parts Allowed
If all of your element inspections are within tolerance, a gap between shoulders is allowed when parts are made-up hand-tight. A gap is still prohibited when parts are made up under proper torque. (API 7-2 7.2.3 Fig. 14)
*API (American Petroleum Institute) maintains 685 standards and recommended practices. Many have been incorporated into state and federal regulations; as well as adopted by the International Organization for Standardization.
