ULTRASONIC
INSPECTION (UT)
Ultrasonic inspection technology is
well accepted by the industry and is an established method for the quantitative
wall thickness measurement and for the detection and sizing of metal loss
features in liquid pipelines. The full recording of the A-scan allows to
maintain the detection and sizing capabilities even in the presence of debris,
wax or paraffin layers on the inner pipe surface. In addition the thickness and
thus the volume of these layers can be determined.
In-line
Inspection using Ultrasonic technology is well suited to address the broad
range of metal loss anomalies present in liquid pipelines and helps to maintain
their structural integrity.
APC
utilizes ROSEN's UT tools for wall thickness inspections and provide direct measurement
technology with high accuracy and reliability. The data can and should be used
for further pipeline integrity assessments and calculations that provide
precise corrosion growth and lifetime evaluation, risk assessment, maintenance
and inspection schedules. Inline inspection and integrity assessment methods in
combination provide an excellent picture for the inspected asset.
