A new revision number will be assigned. They will be balloted separately. Motion made, seconded and passed to ballot the changes of TR 6AF and TR 6AF2.
  24. API 6HP (Earl Shanks) – Earl Shanks presented a report on this task group. It involves groups other than SC6. Work started in 2005 because of high performance requirements in the industry. Object is to develop the design verification and validation process for high pressure/temperature applications. ASME Section VIII procedures are being considered. ASME recommends fracture mechanics methods for the large forgings involved. Stress Engineering was contracted to do the writing. An example procedure was presented at the 2007 conference. Analysis has been performed and data is being formatted for the report. The technical document will proceed.
  1. Summary/Update of Prior Meeting Discussions:

a.20K Flanges/High Strength Bolting Materials (Shyam Patel) - Shyam Patel reported. The task group consists of 6 manufactures, 2 users and 1 consultant. See attachment for details of the report. Flange design and verification are in process (Attachment 6).

b.Transfer of Standards out of SC6 (14A/14B/14L) (Ed Baniak) – Ed Baniak reported that the standards assignments have been concluded. They are now assigned to SC19 and are no longer under SC6.

c.Transfer of Standards into SC6 (11IW) (Ed Baniak) – This document has been assigned to SC6. It may be necessary to contact licensees and users for input on this standard.

  1. Status of Work Plan and Action Plan Update (David Cole):
  2. API Spec 6FD (Fire Test for Check Valves) 1995/Reaffirmed 2003 – The chairman asked for a decision on need to reaffirm or withdraw. Motion made, seconded and passed to ballot Spec 6FD for reaffirmation.
  3. API Spec 6A718 (Nickel Based Alloy 718) 2005 – The chairman reported that we need to be thinking about reaffirmation in the future. Tim Haeberle suggested that we reactivate the task group to evaluate the need for reaffirmation and possible changes. Motion made, seconded and passed to reinstate the 6A718 task group. Volunteers are requested to contact Tim Haeberle.
  4. API Spec 11IW (Independent Wellhead Equipment) Reaffirmed 2008 – The chairman reported that this document is now under SC6. It has been reaffirmed twice with no changes. Interested parties are welcome. It was suggested that licensees and users of this equipment be contacted.
  5. New Business –
  1. Audit Effectiveness (Bud Wrightman) - Bud Wrightman discussed audit effectiveness. Questions are developed for audits of API Spec 6A. A request was made for volunteers from SC6 to rank the questions and develop new ones. An e-mail will be sent to SC6 chair requesting volunteers.
  2. API Bull Plug Issue (David Zollo) - David Zollo presented this issue for AWHEM. It has been found that API bull plugs cannot be made up according to the requirements API specifications. David reported on testing results and recommendations. Coatings are recommended to prevent galling, but torque is still high. Dimensional changes are required to allow proper make-up. Dimensions were presented on the 2” size. New dimensions are recommended to reduce the torque required for make up. Also, bull plugs should not be rated above 10,000 psi working pressure. Other sizes need to be evaluated (Attachment 7). Motion made, seconded and passed to ballot the proposed changes as an Addendum to API Spec 6A to add coatings for all sizes of bull plugs and the dimensional changes presented for the 2” size. Each change (coating and dimensions) will be balloted separately. AWHEM is requested to provide recommendations and dimensions for the other sizes of API bull plugs.
  3. Review of ASME Code Section VIII Division 2-2007 (John Fowler) - John presented a summary of the ASME Code changes and pointed out how API specs are affected. See attachment for details. Recommendations are included. The chairman supports the formation of a work group. It was recommended that SC6 identify people willing to work on this issue (Attachment 8). Motion made, seconded and passed to form a task group to evaluate changes needed to SC6 documents as a result of the new ASME Codes, dependant on outcome of the ECS. John Fowler was appointed chairman of the ASME Codes Task Group. Volunteers are requested to contact him. The ECS will be requested to consider standardizing the design stress analysis methods for all API committees/subcommittees.
  4. Coordination between API committees and ISO groups (Chairman) – The chairman requested and received support from SC6 to work with Ries Langereis to investigate how other API subcommittees are working with their ISO counterparts and bring a report back to SC6 in the 2009 winter meeting.
  1. Actions Item Summary – Five ballot items:
  2. Changes to TR 6AF
  3. Changes to TR 6AF2
  4. Reaffirmation of API 6FD

METALLIC MATERIAL LIMITS FOR WELLHEAD EQUIPMENT USED IN HIGH TEMPERATURE FOR

API 6A AND 17D APPLICATIONS:

Phase I (April 04); Phase II (September 2006); Phase III (November 2008)

PHASE I Abstract:

This API-funded project was conducted by a Task Group charged by the Association of Well Head Equipment Manufacturers (AWHEM). The Task Group examined mechanical properties of metallic materials used for API 6A and 17D wellhead equipment for service above 250ºF. Six different materials meeting API 6A, PSL 3 and 75 Ksi conditions were supplied “in condition” by a variety of suppliers. Yield strength reduction ratios at temperatures of 300, 350 and 400ºF from “mid-radius” specimens were determined. As a result of testing, yield strength reduction ratios ranged from 93% at 300ºF to 89% at 400ºF by averaging results of heats for each type of material. Materials such as AISI 4130 showed the greatest variability due to hardenability issues. These results are intended to amplify data shown in API 6A, Appendix G. (11 page report)

PHASE II Abstract:

This API-funded project was conducted by a Task Group charged by the Association of Well Head Equipment Manufacturers (AWHEM). The Task Group examined mechanical properties of metallic materials used for API 6A and 17D wellhead equipment for service above 250ºF. Phase I of the project tested six different Low Alloy materials meeting API 6A, PSL 3 and 75 Ksi conditions which were supplied “in condition” by a variety of suppliers. Similarly Phase II examined five different corrosion resistant alloys (CRAs). Yield strength reduction ratios at temperatures of 300, 350 and 400ºF from “in condition” specimens were determined. As a result of testing, yield strength reduction ratios ranged from 99% at 300ºF to 76% at 400ºF by averaging results of heats for each type of material. Supplier-furnished data was used for some of the material due to the difficulty in obtaining CRA in tight market conditions. Test results from some labs on certain material produced widely varying results and were removed. Some bad data were due to movement of the specimen or extensometer extensions during testing. Shortages of material precluded retesting. (15 page report)

PHASE III Abstract:

This API-funded project was conducted by a Task Group charged by the Association of WellHead Equipment Manufacturers (AWHEM). The Task Group examined mechanical properties ofmetallic materials used for API 6A and 17D wellhead equipment for service above 250ºF. Themaximum test temperature for mechanical properties was 450°F. The work reported hereinvestigates the short term effect of temperature on the mechanical properties and any long termeffects at these temperatures on the microstructure of these age-hardenable CRA alloys isoutside the scope of this work. Phase I of the project tested six different Low Alloy materialsmeeting API 6A, PSL 3 and 75 Ksi conditions which were supplied “in condition” by a variety ofsuppliers. Phase II tested five different corrosion resistant alloys where the two alloys, nickelalloys 925 and 625Plus/725, failed to achieve a correlation of elevated temperature properties.Phase III was approved by API for a new round of testing on nickel alloys 925 and 625Plus/725.Yield strength reduction factors at temperatures of 300, 350 and 450ºF from “in condition”specimens were determined. As a result of testing, yield strength reduction factors ranged from0.93 at 300ºF to 0.89 at 450ºF by averaging results of heats for each type of material. The resultsfrom Phase III were shown to be in good agreement with supplier-furnished data for the samealloys. (9 page report)
