OVERVIEW:

Non-Destructive Testing (NDT) or Non-Destructive examination (NDE) is the process of inspecting, testing or evaluating materials, components or assemblies for discontinuities (weld / material defects) or differences without destroying the serviceability of the part or system. in other words when the inspection or test is completed, NDT/NDE is used to ensure the quality of materials and joining process during the fabrication and erection phases. in-service NDT/NDE inspections are used to ensure that the products in use continue to have the integrity necessary ensure their usefulness and the safety of the public.

SERVICES:

LIQUID PENETRANT TESTING (PT)

The basic principle of Liquid Penetrant Testing is that when a very low viscosity (High Fluid) liquid   (The Penetrant) is applied to the surface of a part, it will penetrate into Weld/Material fissures and voids open to the surface. Method can be performed Magnetic and Non-Magnetic materials.

PARTICLE TESTING (MT)

Magnetic Particle Testing uses magnetic fields to locate surface and subsurface discontinuities (Weld/Material Defects) in ferromagnetic materials. This method is highly accurate in surface and sub-surface detection.

ULTRASONIC TESTING (UT)

Ultrasonic Testing is non-destructive test method that utilizes sound waves to detect cracks and other Weld/Material defects in parts of the material being tested. Highly accurate Testing method on thick materials.

ULTRASONIC WALL THICKNESS TESTING (WT)

Ultrasonic Wall Thickness is limited form of Ultrasonic Testing (UT) in which ultrasonic waves are used to gauge (Determine) the thickness of different materials.

HARDNESS TESTING (HT)

Hardness is a characteristic of a material , not a fundamental physical property. It is defined as the resistance to the indentation , and it is determined by measuring the permanent depth of the indentation. More simplified , when using a fixed force (load) and a given
indenter, the smaller the indentation , the harder the material.

VISUAL TESTING (VT)

Visual testing is based on the inspection for flaws that are visible to the naked eye and is the most commonly used NDT method across all industries.  It allows for a feasible and fast control of quality at every step of the fabrication or maintenance process.  It is used to detect visible flaws such as deformation, welding defects and corrosion.

MACRO EXAMINATION (ME)

Macro Examination feature the following, quality of the weld in a welding procedure qualification record (WPQR) and welder qualifications.
