  3. 4th Edition Topics – API 16A • Updated Temp chart includes Low/Operating/Extreme levels • Defined HAZ zone 2mm (consistent w/API 6A and NACE) • Established Minimum Design Criteria for 16A equipment 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

  4. 4th Edition Topics – API 16A • Removed 25k & 30k classes (ref 17TR8) • We have 16A representation in 17TR8 (WG formed) • Closure Bolting Hardness per API 20E BSL-2 / API 6A (WG formed) • Gas handling systems are out of scope for 16A, should be in RP-64 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

  5. 4th Edition Topics – API 16A • Sealing characteristics on annulars and ram preventers. (WG formed) • Updated shearing test to include off-center test. • Product history files require additional data, (WG formed) 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

  6. 4th Edition Topics – API 16A • Discussed brinnelling of ring groves during shell test. Ring groove dimensional measurements should be taken as finished machined data before shell test • Document clean up. (ISO replaced) • Discussed establishing PSL levels, agreed 16A criteria already meets PSL-3 criteria. Dropped further consideration.

  7. 4th Edition Work Groups – API 16A • Five Work Groups Formed • Gas testing qualification • Sealing characteristics • PSI-A v/s PSI-G • Closure bolting • Product history records 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

  8. New/Ongoing Discussion Topics • More robust shearing test, i.e. off-center in compression • Designate surface & subsea equipment • Steam temp rating • Closing on flow • 25k & 30k ratings • Define hub face separation for drilling connectors • 5 year product marking requirements • 6A-F flange limits • Should 16A include workover operations in scope

  9. New Temperature Ratings • Table 4 – Temperature ratings of non-metallic sealing materials

  10. Minimum BOP Design Criteria
