Subpart G: General Construction Requirement Under 192
In this section, we delve into Subpart G of the RIN 2 pipeline regulations under Part 192. The focus is on the quality control measures required after a pipeline is installed, particularly the coating condition survey. Techniques such as DCVG (Direct Current Voltage Gradient) and ACVG (Alternating Current Voltage Gradient) are used to detect potential coating damage that could lead to corrosion. The session emphasizes the importance of following specified criteria threshold values for these surveys to ensure accurate and reliable results, critical for maintaining pipeline integrity and PHMSA compliance.
