New ItemAPI Spec 6A: ASME Section V And Section IX Reference Editions

Tim Haeberle

30 June 2011


New item api spec 6a asme section v and section ix reference editions

Current Wording:

Section 2, Normative references

“The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.”

This is not a problem


The problem

The Problem

Current Wording:

Section 2, Normative references

“ASME Boiler and Pressure Vessel Code:2004 with 2005 and 2006 addenda, Section V, Nondestructive Examination

ASME Boiler and Pressure Vessel Code:2004 with 2005 and 2006 addenda, Section VIII, Division 1, Rules for Construction of Pressure Vessels

ASME Boiler and Pressure Vessel Code:2004 with 2005 and 2006 addenda, Section VIII, Division 2, Alternative Rules

ASME Boiler and Pressure Vessel Code:2004 with 2005 and 2006 addenda, Section IX, Welding and Brazing Qualifications”

This is where the problem begins.

Only Section VIII should be a dated reference!


History

History

  • In 2009, the Design TG identified a need to use the 2004 Ed of ASME Section VIII, Div 1 & Div 2 for API 6A, API 16A, & API 16C, rather than the 2007 Ed.

  • ASME Section VIII 2007 permitted higher stress, but required CharpyV-notch values that were deemed to be too high for the 75 K and 80 K steels.

  • The recommendation from the Design TG was to use the 2004 Edition for all of the referenced ASME Sections, rather than “cafeteria shop” and use the design rules, but not the material quality control.

  • However, this creates a problem for weld facilities and equipment manufacturers that, for the sake of compliance with the ASME B&PVC, need to qualify new weld procedures in accordance with the current edition of ASME Section IX.

  • Additionally, this creates a problem for raw material suppliers and equipment manufacturers that, for the sake of compliance with the ASME B&PVC, are working to the current edition of ASME Section V.

  • Raw material suppliers and equipment manufacturers are working to standards other than API Spec 6A that require compliance with the latest edition.

The ASME B&PVC 2010 edition is the current edition.


History1

History

  • The Design Task Group also noted in it’s minutes from the 18 June 2009 meeting:

    “At some point there should be a rewrite of the design sections of the standards to incorporate the methods of the 2004 Code, eliminating the problem of referencing an obsolete standard. One possibility would be a separate API Standard that could be referenced by each of the equipment specifications.”

  • This has not happened.


The problem1

The Problem

Current Wording:

7.4.2.2.14 Weld NDE — Volumetric

The following apply:

d) test method for ultrasonic examination:

Ultrasonic examinations shall be performed in accordance with procedures specified in ASME, BPVC:2004, Section V, Subsection A, Article 4.

All of the references to Section V use the obsolete 2004 Edition.


The problem2

The Problem

Current Wording:

“6.2 Non-pressure-containing weldments other than weld overlays — PSL 1 to PSL 3

The following apply:

a) welding procedure/performance:

Welding procedures and performance qualifications shall be in accordance with ASME BPVC:2004, Section IX, Articles II and III with 2005 and 2006 addenda.”

All of the references to Section IX use the obsolete 2004 Edition,

with the obsolete 2005 and 2006 addenda.


The problem3

The Problem

Current Wording:

“6.3.2.3 Welding procedure qualifications

The following apply:

a) written procedure:

Welding shall be performed in accordance with welding procedure specifications (WPS), written and qualified in accordance with ASME, BPVC:2004, Section IX, Article II. The WPS shall describe all the essential, nonessential and supplementary essential (if required; see ASME, BPVC:2004, Section IX) variables.”

The PQR shall record all essential and supplementary essential (if required) variables of the weld procedure used for the qualification test(s). Both the WPS and the PQR shall be maintained as records in accordance with the requirements of 7.5.”


The problem4

The Problem

Current Wording:

“6.3.2.3 Welding procedure qualifications

b) base metal groupings:

The manufacturer may establish a P-number grouping for material(s) not listed in ASME, BPVC:2004, Section IX.”


The problem5

The Problem

Current Wording:

“6.3.2.4 Welder performance qualification

The following apply:

a) testing requirements:

Welders and welding operators shall be qualified in accordance with ASME, BPVC:2004, Section IX, Article III.

b) records:

Records of welder performance qualification (WPQ) tests shall be in accordance with ASME, BPVC:2004, Section IX.”


The problem6

The Problem

Current Wording:

“6.3.3.2 Welding procedure qualification

The following apply:

a) base metal groupings:

Each base material that is not listed in an ASME, BPVC:2004, Section IX, P-number or S-number grouping shall be specifically qualified by the manufacturer.”


The problem7

The Problem

Current Wording:

“6.5.1.1.2 Welding procedure/performance qualification

Qualification shall be in accordance with ASME, BPVC:2004, Section IX, Articles II and III, for weld overlay.

The following apply:

a) chemical analysis:

Chemical analysis shall be performed on the weld metal in accordance with the requirements of ASME, BPVC:2004, Section IX, at a location 3 mm (0,125 in) or less from the original base-metal surface. The chemical composition of the deposited weld metal at that location shall be as specified by the manufacturer.”


The problem8

The Problem

Current Wording:

“6.5.1.2.2 Welding procedure/performance qualification

Qualification shall be in accordance with ASME, BPVC:2004, Section IX, Articles II and III, for weld overlay.

The following apply:

a) chemical analysis:

Chemical analysis of the weld metal shall be performed in accordance with the requirements of ASME, BPVC:2004, Section IX, at the minimum overlay thickness as specified by the manufacturer for the finished component.”


The problem9

The Problem

Current Wording:

“6.5.1.2.2 Welding procedure/performance qualification

d) guided-bend tests:

Guided-bend tests and acceptance criteria shall be in accordance with ASME, BPVC:2004, Section IX, to confirm weld overlay/base material bond integrity.

“6.5.2.2 Welding procedure/performance qualification

Qualification shall be in accordance with ASME, BPVC:2004, Section IX, Articles II and III, for weld overlay, hard facing or other types of overlay, as applicable.”


The solution

The Solution

Proposal:

  • Revise API Spec 6A Twentieth Edition and ISO 10423:2009 to change all references to the ASME Boiler and Pressure Vessel Code Section V to an undated reference.

  • Revise API Spec 6A Twentieth Edition and ISO 10423:2009 to change all references to the ASME Boiler and Pressure Vessel Code Section IX to an undated reference.

  • Leave the references to the ASME Boiler and Pressure Vessel Code Section VIII as a dated reference that specifies the 2004 Edition with 2005 and 2006 addenda.


The solution1

The Solution

Justification:

  • The use of the obsolete edition of ASME Section V for NDE creates a problem for raw material suppliers and equipment manufacturers that, for the sake of compliance with the ASME B&PVC, are working to the current edition of ASME Section V.

  • Additionally, the use of the obsolete edition of ASME Section IX for welding creates a problem for weld facilities &equipment manufacturers that, for the sake of compliance with the ASME B&PVC, qualify new weld procedures in accordance with the current edition of ASME Section IX.

  • In many cases, the facilities performing NDE and welding on API 6A equipment are also working to other national and international standards that are up to date and require compliance with the latest editions of ASME Section V and Section IX.
