SUBCONTACT MAGNETOMETRIC DIAGNOSTIC SYSTEM

Sub-contact diagnostics of steel

tanks, pipelines and stressed

metal constructions of various

types,

Accurate localization of defects,

Instrumental detecting of flaw,

No disruption of operations,

3

Does not require removal of the insulating coating, insulating materials, protective

and anticorrosive materials from the surface of the inspected object.

KMD-03M TECHNOLOGY

The principle of operation of the device is based on the registration of local changes in the natural magnetization of the structure resulting from various defects (Villari effect),

Received data is visualized as the colorized magnetograms showing the location of anomalies (flaws).

KMD-03M

Magnetic induction lines

SUBCONTACT INSPECTION METHOD

Subcontact diagnostics is possible for the coating thickness up to 40 mm,

Stopping or changing the operating mode is not required – No lost production,

No preparation needed,

High speed - up to 100 m2 daily

per 1 crew,

Detects flaw in real time,

Reliability reaching 95 %.

5

SUBCONTACT INSPECTION PROCEDURE

KMD-03M provides remote non-contact inspection of above ground, underground and underwater steel pipelines of any type without any interruptions of the operation or any preparations.

4. Map of the defects distribution on the surface of the tank, indicating the loss of metal.

6

1. Subcontact Inspection. 2. Data processing. 3. Contact tests.

INSPECTION WORKFLOW

STAGES OF WORK

I. PREPARATION Collecting all necessary information about the pipeline and preparing

the measuring equipment.

II. FIELD DEPLOYMENT

Visual survey of the object. Field inspection with KMD-03M system

– magnetometric subcontact inspection without removing the

cover.

Marking of the flaws directly on the inspected surface.

III. AFDT (Additional

Flaw Detect Tests)

Additional control by non-destructive methods (measuring of

thickness and hardness).

IV. REPORT

The report and the final condition conclusion on the technical state of

the object, including the “The conclusions about the technical

condition of the object“. 7

VISUALIZATION OF THE MAGNETIC FIELD

8

Received data is visualized as colored magnetograms showing the places of anomaly (flaw) as

red spots and normal area as colored green and blue.

Spots of corrosion.

Not-stressed (normal) welding joint.

DETECTABLE DEFECTS

Metal thinning caused by corrosion,

Failures of solidity (bundles, caverns, lack of fusion,

bullies),

Change in geometry (dents, bumps),

The stresses concentration zone arising in result of

fatigue processes.

KMD-03M detects anomalies of the magnetic field caused by various types of defects:
