Ultrasonic inspection introduces beams of high frequency sound into the piece. The sound reflected at material interfaces is analyzed to define the presence and location of discontinuities.

Angle beam ultrasonic flaw detection is used to inspect welds using the shear wave mode of transmission to detect welding discontinuities such as linear defects and volumetric defects. High penetrating power, which allows the detection of flaws deep in the part. High sensitivity, permitting the detection of extremely small flaws. Only one surface need be accessible. Greater accuracy than other non-destructive methods in determining the depth of internal flaws and the thickness of parts with parallel surfaces. Some capability of estimating the size, orientation, shape and nature of defects

UTG, ultrasonically measures the wall thickness of materials such as steel, plastic and also the metal thickness of a painted structure without having to remove the coating . It is ideal for measuring the effects of corrosion or erosion on tanks, pipes or any structure where access is limited to one side, Class Special /Renewal / Periodical Survey, Annual /Intermediate Survey, Condition Assessment Program (CAP), Survey Condition Assessment Scheme (CAS) Survey, Transfer of Class (TOC) Survey, Owner’s Requirement Survey.

Provision of worldwide vendor inspection/expediting services for bought out items during manufacturing to ensure their compliance with required specifications before dispatch to clients through reputed international Inspection agencies.

Design review of pressure vessels, piping, storage tanks, structural etc to verify compliance to various international standards such as ASME, BS, API etc. Provision of Resident Inspectors (welding/piping/mechanical/civil/E&I) to other TPI agencies or reputed EPC contractors on short or long term basis.

Visual Examination is generally used to determine such things as the surface condition of the part, reinforcement and undercutting of welds, alignment of mating surfaces, shape or evidence of leaking. Methods employed may be either:

1. direct visual examination
2. remote visual examination
3. translucent visual examination using artificial directional lighting.

Matrix provides certified Visual Inspectors to various codes, such as: AWS, API, ANSI /ASME, and ASNT

Magnetic Particle testing is a versatile inspection method used for field and shop applications. Magnetic particle testing works by magnetizing a ferromagnetic specimen using a magnet or special magnetizing equipment.

If the specimen has discontinuity, the magnetic field flowing through the specimen is interrupted and leakage field occurs. Finely milled iron particles coated with a dye pigment are applied to the specimen. These are attracted to leakage fields and cluster to form an indication directly over the discontinuity. Can detect both surface and near subsurface indications. Can inspect parts with irregular shapes easily. Pre-cleaning is not as critical as for some other inspection methods. Fast method of inspection and indications are visible directly on the specimen surface.
Liquid Penetrant Testing

The Liquid Penetrant Method is used to detect discontinuities which are open to the surface of the material being examined. This method may be used on both ferrous and nonferrous materials. Liquid Penetrant examination may be used for the detection of surface discontinuities such as cracks, seams, laps, cold shuts, laminations and porosity, Matrix provides both visible and fluorescent Liquid Penetrant Examination Services.

Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation.

Indentation hardness value is obtained by measuring the depth or the area of the indentation. The followings are the most common hardness test methods used in today`s technology:

• Rockwell hardness test
• Brinell hardness
• Vickers
• Knoop hardness
• Shore
