Advances In ILI Allow Assessing Unpiggable Pipelines

摘要

Typically, this operator utilizes magnetic flux leakage (MFL) ILI technology for inspecting pipelines and ensuring regulatory compliance. However, an as-built survey indicated a 90-degree bend with a possible bend radius of ID or a mitered bend. Additionally, a minimum bore of 10.25-inch was discovered with a gauge plate. The 16% reduction could not be negotiated bv the MFL tool. Within a week of beine contacted.
