HISTORICAL DOCUMENT. Stress corrosion cracking direct assessment (SCCDA) is a structured process that is intended to assist pipeline companies in assessing the extent of stress corrosion cracking (SCC) on a section of buried pipeline and thus contribute to their efforts to improve safety by reducing the impact of external SCC on pipeline integrity.  Primary guidance for assessing the structural integrity of a pipeline that has a significant risk of containing stress corrosion cracks is provided in Part A3 of ASME(1) B31.8S,1 which identifies several options for inspection and mitigation activities.  The recommended practice for SCCDA presented in this standard addresses the situation in which a pipeline company has identified a portion of its pipeline as an area of interest with respect to SCC based on its history, operations, and risk assessment process and has decided that direct assessment is an appropriate approach for integrity assessment.  This standard provides guidance for managing SCC by selecting potential pipeline segments, selecting dig sites within those segments, inspecting the pipe, collecting and analyzing data during the dig, establishing a mitigation program, defining the reevaluation interval, and evaluating the effectiveness of the SCCDA process.

NACE SP0206-2006, Internal Corrosion Direct Assessment Methodology for Pipelines Carrying Normally Dry Natural Gas (DG-ICDA)

Product Number: NACE SP0206-2006
Publication Date: 2006
$179.00

HISTORICAL DOCUMENT. This standard practice formalizes a methodology termed internal corrosion direct assessment for pipelines carrying normally dry natural gas (DG-ICDA)1,2,3 that can be used to help ensure pipeline integrity.  The methodology is applicable to natural gas pipelines that normally carry dry gas, but may suffer from infrequent, short-term upsets of liquid water (or other electrolyte).  This standard is intended for use by pipeline operators and others who manage pipeline integrity.
