Pipe Quality Action Plan - INGAA

1. Identification of Low and Variable Yield Strengths in High Strength, Low Allow Line Pipe Steel

2. Line Pipe Quality Management

3. Evaluation of Enhancements to API Pipe Standards

4. Evaluation of Enhancements to Operator Specifications and Practices

5. Evaluation of Enhancements to Pipe Manufacturer Specifications and Practices

6. Understanding Steel Stress Strain Behavior and Pipe Expansion

7. Development of Methods to Understand Implications of Expansions on Stress and Strain and Implications to Each Threat in ASME B31.8S

8. Evaluate Implications of Expansions on Pipe Coatings 13

API 5L - modifications • API 5L – proposed changes for “low strength” pipe

– QA management system for the supplying steel and rolling mill

– Standard sampling locations along plate or coil length according to documented procedures

– Modifications to retest procedures

– Manufacturing Procedure Specification

– Inspection and Test Plan

– Manufacturing Procedure Qualification Tests – mechanical tests

– Qualification consider assessment of coil/plate tensile property variability and coil/plate to pipe strength changes

Materials - Quality Management

• What procedures and standards are being used? – Manufacturers

– Industry • API, ASTM, MSS, etc.

– Operators

• Is it a DOT Code referenced standard?

Records Management

• What are the first items looked at if a pipeline has an incident? Records!

– Material Records – pipe, fittings & fabrications, etc.

• QA and QC

– Standards – API, ASME, ANSI, MSS, and ASTM

– Tests – mechanical & chemical properties, welding, NDE, and hydrotest

– Design and Construction Records

– Operations and Maintenance Records

– Integrity Management Records

Looking Ahead

• Quality – focus on – Pipe, fittings, fabrications and coatings – Field Construction – welding, coatings, backfill, &

inspection – QA and QC – on-site inspection

• May need to explore other options: – More effective regulations and standards – Operator qualification for construction personnel

• PHMSA inspection focus on quality will continue
