PRIMARY SERVICES

Advanced NDT and Engineering Integrity Assessment Division

In this area of business, we are focusing on providing services utilising basic NDT and
advanced NDT. Specifically, we are offering services in the non-destructive testing
(NDT) services and also in the area of integrity monitoring, analysis and assessment.
ZNRTSB is also the expert in the newly developed advanced NDT technology called
Strain-Stress Technology in Malaysia and South Asian Region.

Basic NDT

For basic NDT, we are providing technology services based on Ultrasonic Testing (UT),
Radiography Testing (RT), Eddy Current Testing (ECT), Magnetic Particle Testing
(MPT) and others basic or conventional NDT technology in fulfilling the requirement
of engineering integrity assessment. We’re also providing man-power and services for
inspector in welding, QA/QC, API 510, API 570 and API 653.

Advanced NDT Technology

For advanced NDT technology, we are focusing in providing the services based on an
emerging NDT technology known as Strain-Stress Analysis and Acoustic Emission
technology. Besides the collaboration with our principle, we also developed our own
local expert in bringing the technology into this region.

Strain-Stress Technology

ZNR Tech is among the pioneer in the area of Strain-Stress
technology in Malaysia and Southeast Asia region.
Strain-Stress technology is considered as an advanced NDT
technology and recognized by the ISO standard with the
corresponding code number, ISO 24497.
ZNR Tech has been collaborated with Dept. of Mechanical and
Manufacturing Engineering UKM for the Strain-Stress technology.
Based on the collaboration works, a new 3D stress contours has
been successfully developed by UKM team.

Strain-Stress Analysis (S-S A) Technology

Classified in two main types namely contacting and non-contacting S-S A.
The only technique (among all the magnetic NDT technology) in which the S-S A
technology monitor, detect and measure the natural self-magnetic waves emitted by
engineering components and structures.
Fast screening inspection technology for welding, engineering components and
structures.
Capable of monitoring and detecting Stress Concentration Zones (SCZ) or weak areas
(SCZ’s, high stress-strain area) in engineering components, structures and welding.
Capable of detecting micro-size defect with the smallest defect diameter of 5 µm and
shortest defect length of 25µm.
Capable and detect defects such as crack, corrosion, erosion, metal loss and welding
defects.
Capable of measuring the strain and stress profiles of engineering components,
structures and welding. Stress and stress are the main parameters utilised for
engineering failure analysis.
Capable of inspecting pipe under insulation including the fire proofing material (calcium
silicate) without removing the insulation.
Capable of inspecting buried piping without any excavation. This is accomplished using
the non-contacting S-S A technology scanning devices.
