API 7-2 Second Addition

Companies working to the latest API 7-2 standard had until JUne 6 2017 to comply with the latest specification. Gagemaker, a leading developer and manufacture of precision mechanical inspection equipment for the Oilfield, Mining, Water Well, and General Machining industries has highlighted some key points below.

Requirements of indicator resolution have been updated for all lead, height, and taper gages. (API 7.4.1, 7.5.2, 7.6*) Now gages with
alternate indicators may not meet the new API requirements and must be replaced. Gagemaker recommends that you check your gages ASAP. Gagemaker has compiled a complete list of indicators and their compliant replacements at www.gagemaker.com/apiupdate.

  • New Bevel Diameters
  • Tables for connection bevel diameters have changed. (5.2.2)
  • Drawings Require New Angles All RSC box drawings now require a 30°max back-of-the-box angle. (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. (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. (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.
