The document describes a new contactless pipeline inspection technology called KMD-01M. It uses magnetometers to detect defects in pipelines from the surface without disrupting operations. The technology is based on nanofilm sensors that can detect weak magnetic fields from defects. It can identify a variety of defect types and has inspected over 10,000 km of pipelines accurately. The system offers advantages over traditional inspection methods like lower costs and ability to inspect underwater or inaccessible areas.

More than 10% of Russian pipelines are impassible for the traditional (in-tube and contact)
diagnostics methods due to the technical limits (underwater crossings etc)
Existing NDT methods are costly, labour-intensive, time consuming, require considerable
customers resources to attract, multiple runs of the pig, stop and / or changing the mode of
transportation of product, which leads to owners significant associated losses
Providing industrial safety of oil and gas pipelines by implementing qualitative and moderate
diagnostics is the issue not only environment protection but the factor providing economic stability
of the pipelines operating enterprises

3. SOLUTION – KMD-01M
The principally new approach to pipelines technical inspection by contactless magnetometric diagnostic method
using high-tech system KMD-01M
The contactless magnetometric diagnostic system KMD-01M consists of:
Data saving and Additional
3-component magnetometers unit
visualization unit equipment

4. PHYSICAL PRINCIPLES of KMD-01M OPERATING
The systems work is based on the Villari effect (magneto-elasticity effect ) which means the
changing of the magnet magnetization under the influence of mechanical deformations and
stresses in the pipes metal

5. NOVELTY
The device KMD-01M is based on the thin-film magneto-resistive transducer,
which measures full magnetic induction vector in the four points
One of the main factors determining the high sensitivity of KMD-01M and
diagnostics selectivity is applying of magnetic nano-films having the range of
advantages
Nano-films key advantages:
• High magnetic sensitivity
• Wide range of operating frequencies
• Low hysteresis
• Low voltage bias
• Low temperature drift
• Low temperature coefficient of
sensitivity

6. NANOTECHNOLOGY COMPONENT
Principles of the contactless diagnostics require
applying high sensitive sensors able to register
extremely weak magnetic fields at the distance from a
pipeline
The main sensitive element of the magnetic field
sensors is ferrite made as the nano-film on the silicone
plate
The ferrites size and its composition defines the
sensitivity, selectivity and speed of the sensors

The best characteristics have the magnetic films we

thickness from 10 nm to 30 nm and the thickness of S i,

12. METHODIC OF MEASURING WITH KMD-01M
Complex is operated by two operators: :
The first operator locates the pipeline with the pipeline finder
as well as links the route with the GPS receiver to the reference
points
The second operator measures the fluctuations of the constant
magnetic field with the magnetometers.
Based on the received data the areas of stress concentration due to
the corrosion teat-and-wear, stressed-deformed condition, pipelines
geometry failure, and other defects are defined
While measuring the system automatically records the GPS-
geographical coordinates.
The processing and interpretation of the received data take place
after the measuring.

13. THE TECHNIQUE OF PIPELINES COMPLEX DIAGNOSTICS
The complex diagnostics of oil & gas pipelines technical conditions is
carried out in four stages:
I stage Collecting all necessary information and preparing the measuring
equipment.
II stage Field inspection with КМD-01М – magnetometric contactless
measuring with the simultaneous data visualization. At the
same time detecting of GPS - coordinates is made.
While working the received data can be transferred to the Data
Processing Centre through Internet.
III stage The processing and interpretation of the received data is held.
By the customers request the opening of the pipeline can be
made with the NDT - additional control by non-destructive
methods (measuring of thickness and hardness).
IV stage The analysis of the received information is executed, the
electronic maps of the discovered anomalies are designed and
then the final objects technical condition conclusion is made.
