NACE International presented a Pipeline Integrity Direct Assessment Seminar in Houston, TX on June 23-25. The seminar addressed external corrosion direct assessment, internal corrosion direct assessment and stress corrosion cracking. It provided a detailed description of the four-step process and the tools available to implement direct assessment.
NACE Task Groups are currently in the process of developing the following Standards to accommodate the DOT/OPS Direct Assessment Requirements.
NACE TG293 – Internal Corrosion Direct Assessment on Dry Gas Pipeline Systems (final draft revision).
NACE TG305 – Internal Corrosion Direct Assessment on Wet Gas Pipeline Systems (early development).
NACE TG315 – Internal Corrosion Direct Assessment on Liquid Pipeline Systems (early development).
NACE TG273 – Stress Corrosion Cracking Direct Assessment (final draft revision).
API Standard 1163 that addresses In-Line Inspections of Pipeline Systems is currently under review with an expected distribution release by the end of year 2004.
API Standard 1110 for the Hydrostatic Pressure Testing of Pipelines is currently being revised to address various pipeline integrity threats. The anticipated distribution release date is unknown.
