The Forensic expert kollegium conducts non-destructive testing of steam and hot water pipelines using visual, capillary, and ultrasonic testing, as well as measurement of weld metal hardness.

During visual inspection of welded joints, experts of the Forensic expert kollegium identify:

• deviations from weld dimensions and shape;
• deviations from straightness of welded pipe joints;
• single inclusions, clusters of inclusions;
• cracks of all types and directions;
• undercuts of the base metal;
• lack of fusion (incomplete fusion) between the base metal and the weld, as well as between weld beads;
• metal overflows (runs) and spatter;
• unwelded craters;
• fistulas;
• burn-throughs.

In order to clarify the results of visual inspection, capillary testing of welded joints may be conducted to determine surface defects.

Internal defects of welded joints are identified by experts of the Forensic expert kollegium using ultrasonic testing, during which the following are examined:

• longitudinal and transverse butt joints of pipelines;
• corner joints with branch pipes (pipes) with full penetration (without intentional incomplete fusion);
• junction areas of longitudinal and transverse butt welds;
• butt joints of segmented bends.

Depending on the diameter and weight of pipeline elements, experts of the Forensic expert kollegium may perform non-destructive testing of weld metal hardness using dynamic or ultrasonic measurement methods without dismantling the pipeline elements. As a rule, hardness measurement is performed for:

• welded joints of pipelines subjected to heat treatment;
• welded joints of welded branch pipes (pipes) to headers and pipelines subjected to heat treatment, as well as without heat treatment.

Non-destructive testing of steam and hot water pipelines at the Forensic expert kollegium is carried out by full-time qualified specialists who are both experts in the design and safe operation of steam and hot water pipelines, as well as certified specialists in various methods of non-destructive testing.

All measurements and tests are carried out using verified measuring instruments included in the State register of Measuring instruments of the Republic of Belarus, according to methods established in technical normative legal acts effective in the territory of the Republic of Belarus and the Customs union.
