Remote Detection of Risk Areas in Metal Structures
"Transkor's Magnetic Tomography Method
is well beyond what's happening in the pipeline industry globally."

Vice President, Pipeline Integrity for Enbridge Pipelines Inc.
Since last century, multinational corporations have been
trying to cope up with
Transkor's Magnetic Tomography technology.
All them failed.
Transkor's magnetic tomography technology is
technology in the world
that can detect defects and risk areas in pipelines
hundreds times faster, cheaper and more reliably
than conventional technologies used by all others.

Transkor-K, Russia is the world’s leader in innovation of the
Magnetic Tomography Method (MTM). Actually, Transkor
invented the Magnetic Tomography Method.
performs the following activities: designing and
manufacturing of unique devices and systems for
non-destructive testing of technical condition of
pipeline systems (including unpiggable), and also
carrying out works for increasing reliability and safety
with their products in the sectors of the national
economy related to operation of pipelines, reservoirs,
etc. For the last 16 years the patented metal control
devices for 100% of the pipelines has passed the
large-scale industrial approbation at the facilities of
30 countries, in the largest operators of the oil and
gas sector and confirmed the reliability of the data at
a level of more than 85%.
To monitor pipelines which are not subject to ILI in 2001 MTM was
developed - the technology of continuous magnetic field scanning of
the entire length of pipeline.
Dependences between the magnetic and
mechanical properties of pipe steel have been found. In 2002-2010
many tests were carried out such as: search and evaluation of
defects and clusters with defects of different nature; search and
evaluation of stress concentration zones in conditions of rough
terrain, both under internal pressure and absence of pressure;
search for the weakest section on a pipeline of limited length.
Fast Inspection of
In 2011 MTM was adapted to evaluate the state of underwater
pipelines (Aqua MTM™).The essence of technique is in the continuous
scanning of 3D magnetic field along the pipeline axis, construction
of a stress distribution map, selection of limit criteria for
specific pipeline operating conditions and the determination of VAT
anomalies associated with changes of mechanical stresses. As device
carriers for purposes of underwater inspection could be used ROV,
AUV and diver.
Technology based on MTM, which goal is to calculate the actual
mechanical stresses distributed along the axis of the given
pipeline. This is achieved by determining relationship of the
parameters between magnetic and mechanical fields of pipeline.
a result, MTM identifies the exact location of areas with increased
concentration of mechanical stresses (VAT anomalies)
the level of their danger based on the values of maximum local
Common pipeline safety procedures determine the values of mechanical
stresses obtained by calculations (FEM, Rstreng, etc) based on
knowledge of the distribution of defects, their size and location.
The information about defects and their properties can be obtained
both with the use of standard means of ILI (In-line inspection) and
with the help of NDE tools at sampling points (in digs). There are
other ECDA / ICDA standards that result in indirect risk assessment
It should be noted that for selective digs areas for dissection
selected by the operator basing on subjective expert assessments and
experience. Safety of entire pipeline is based on interpolation of
these results into entire length.
conventional pipeline inspection methods, the risk of missing a
serious defect remains high
since less than 2% of the length of pipeline is monitored.
Magnetic Tomograpy technology delivers
much more reliable results much faster and much cheaper!
