Remaining Strength of Corroded Pipe Direct Assessment Process

摘要

Remaining Strength of Corroded Pipe Direct Assessment (RSCP DA) process can be used as an assessment metal loss technique to verify In-Line-Inspection (ILI), External/Internal Corrosion Direct Assessment (EC/ICDA) and other inspection data which is used in determining the safe pressures and thereby validate the operator's ongoing integrity management program. This is accomplished by evaluating and verifying the metal loss defects such as corrosion and mechanical damage such as a gouge with the stress cracking concentrator removed. The RSCP DA process provides a pipeline operator with a basis for the determination for repairs or not.
