B31.8 & B31.8S
High‐lights
Hierarchy of Use
•
Regula>ons are the law:
– instruc>ons from Congress in 2002, newest this year
– gave rise to the PHMSA Regula>ons in 2003, & updates
49CFR192 and the new
Part “O” – IMP
FAQ – interpreta>ons
Protocols
DIMP & 80%
Call up ASME B31.8 & B31.8S
which in turn
Requires the use of other standards
Integrity Standard Inter‐Rela>onships
ASME B31Q – Qualifica>ons
API 1162 – Public Awareness
API 1165 – SCADA
API 1166 – Excava>on Safety
Mi>ga>on & Response
Limits + Ac>vi>es + Requirements
Corrosion – B31G, RSTRENG, etc
Dents – App R, API‐579, etc
Individual Threats as in B31.8S
Welding – API‐1104 20th
Pipe – API‐5L 44th
INGAA suggests using B31.8S,
both inside and outside HCAs
Integrity Assessments
1) Hydro-test – API 1110, Performance
2) ILI – API-1163, Equipment Performance
+ ASNT ILI PQ 2006, Analysts & Managers
+ NACE SP 0102, Operations Expectations
3)Direct Assessment
+ NACE SP0502, ECDA
+ NACE SP0206, dry gas ICDA
+ NACE SP0204, SCCDA
+ NACE SP0507, ECDA Data Exchange
+ future wet gas ICDA &
+ CDA now only in 49CFR192 Part ”O”
4) New Technologies
Progress
• Expec>ng new edi>ons for Christmas
– B31.8 is expected in November 2009
– B31.8S is expected in December 2009
• More than 50 updates, Interpreta>ons &
Errata
• Incorpora>ng other new standards
– Good prac>ce, other exper>se
– Common expecta>ons, & consistent applica>on,
B31.8 Hi‐lights
• Some new language

Review of appendixes
Addi>on of helpful reports
• Seismic Design, Yellow Pages, Vintage Pipelines, etc
B31.8S Hi‐lights
• Metrifica>on of B31.8S
• NACE standards for DA incorporated
– NACE Standards called up in 2 and the appendix
– Appendix B goes away
• New language in A3 for near neutral SCC
• Table 3 and figure 4 agree and a defini>ons have been
>ghtened or added, such as failure pressure
• Table 4 for Repair has been updated
• Fa>gue language has been added
• Table 10 new Overall Performance Measures
• Other standards added such as API 1162
What else?
1. B31.8 & B31.8S together address design and ops
2. Life Cycle Design (includes cradle to grave risk)
–
–
–
Provides design alterna>ves to address threats
Requires more performance and loading knowledge
Will cover the 80% SMYS opera>ons
3. Reliability Based Design Assessment
–
–
–
Provides considerable alterna>ve design op>ons to
ensure each threat is properly addressed
Requires considerable knowledge of the load
resistance and system performance
