TA-3002 Thread Addendum Gage Inspecting a Part
Thread addendum is now a required, mandatory element to be inspected.
Why is it required?
API tubing, casing, and line pipe threads are governed by the Specification 5B. The Sixteenth Edition has made some major changes, including mandating the inspection of thread addendum. 5B 1.2 lists out the new inspection requirements including addendum. 5B 4.8 states that all threads shall be controlled in accordance with gauging practice requirements in Section 6. Further, 5.5.2 explicitly states that “addendum shall be measured on round thread.” The foreword points out that “the term ‘shall’ denotes a minimum requirement in order to conform to the standard”, or more simply, you must do this or be in violation of your license.
