Changes for API 6A 21st Edition Presented at API 6A TG 2 Meeting June 26th 2013 1. Casting and forgings – MATERIALS ‐
Provide additional guidance in Annex A proposed in meeting minutes from 2009 winter
meeting (on API website) DESIGN
o Proposal was to add language to Annex A to provide guidance or limits for service applications
TG Notes from July 2010 stated "Within a given PSL, castings and forgings should
possess an equivalent integrity level". MATERIALS
Could work done on 20A be of use here? MATERIALS
Reference George Hill report from SC‐6 Winter meeting
2. Consider SC 20 document references to standard. Consider informative annex that provides
suggestions for relating SC20 quality levels to PSL levels in 6A or to the service applications of
equipment. MATERIALS/ORGANIZATION/QUALITY
a. Gap assessment of 6A versus 20 series documents
b. Determine how to link SC‐20 requirements to API 6A requirements
c. Guidance – as an example “Products which meet the requirements of 20A meet the
requirements of this specification”
3. Make reference to Q2 requirements in 6A to address maintenance of service tools. Consider
adding Q2 reference in Annex H and expand to include maintenance. NA
Current Annex H only addresses design and manufacture of service tools.
Another alternative is to expand the Repair and Remanufacture Annex J to capture
requirements specific to service tools or develop a separate maintenance document for
service tools
Clause 1.1 states "This International Standard does not apply to field use, field testing or
field repair of wellhead and christmas tree equipment."
4. Address requirements for fittings (test, vent and grease) that would better clarify what are the
barriers or critical parts, materials of construction, qualification, quality, what needs to be tested
during FAT and requirements for fittings in HH clad equipment ( partial penetration
welding/inspection, threads/fitting prep in clad material, fittings and ports in base
material)/define weld overlay surfaces for test,vent and grease ports.
Following are current issues that with the guidelines in API 6A regarding hardness testing of weld procedure qualifications.
1. API 6A establishes its intent regarding hardness testing early on under PSL 1 requirements 6.3.2.3.d) Second Paragraph The manufacturer shall specify the hardness testing locations in order to determine maximum hardness. Testing shall be performed on the weld and base‐material HAZ cross‐section…. Under PSL 3 requirements, guidelines are more prescriptive in that we are told where to perform that hardness tests. Unfortunately, they are contradictory and inadequate. 2. 6.3.4.2.3.a), 4th paragraph & Figures 4 & 5 (Hardness testing of Groove Welds) For all thicknesses, HAZ hardness tests shall be performed in the base material within 2 mm (1/16 in) of the weld interface……. As we move further from the fusion line, hardness in the HAZ drops, so when the 2 mm was added to 6A, it allowed labs to move even farther away from the fusion line. Depending on
