Long Range UT
Technique (LRUT) for Inspection of
In-Service Tank Floor
Above Ground Storage Tank Floors
(AST) in O&G industry are rapidly
prone to corrosion. Corrosion in
annular plates of AST occurs on both
TOP and UNDER Side. Any leakage
creates a huge risk to the
unavailability of the tank and
contamination to the environment.
LRUT is the best technique for Rapid
Scanning of the Large Areas (mapping
of defects from annular plate in
above ground storage tanks) Linear
Scanning Along the Shell. It
is an in service annular screening
tool for AST covering up to a
maximum of 1.2 m from the tank shell
and similar projection plate and
sometimes AST bottom plate depending
on annular size.
Inspection software package provides
the pitting (corrosion damage)
mapping of the plate through the
linear scanning along the plate
edge, for example the lip of annular
plate, with capturing, processing
and storing of all received
ultrasonic signals (A-Scans). The
mapping procedure may be encoded
(true-to-scale) or timed.
