Tensile Test

There are three typical definitions of tensile strength: Yield strength – Ultimate strength & Elongation.

Tensile Testing for

Bend & Rebend Test

Bend tests deform the test material at the midpoint causing a concave on the surface or a bend to form without the occurrence of fracture and are typically performed to determine the ductility or resistance to fracture of that raw materials & Welded coupons ( Pipes, Plate, tubes, )

Flatting & Flaring Test

Flatting Test

Detect microscopic internal and external flaws. It involves compressing a tubular ring between two planes parallel to a predetermined distance.

Purpose: Incipient cracks and internal or external defects which occur as result of this process are not permissible.

Flaring Test

The forming behavior of tubes or pipes which is expanded to a specific degree. This flaring test is carried out in conformity with the code requirements.

Purpose: The specimen to be tested is expanded in a press to the degree specified. Defects which occur as result of this process are not permissible.

Charpy Impact Test

The purpose of impact testing is to measure an objects ability to resist high-rate loading. It is usually thought of in terms of two objects striking each other at high relative speeds

Hardness Test

Hardness testing assesses the impact of the metal or alloy to permanent indentation, and the depth or size of the indent is measured to determine a hardness value.

Purpose of Test:

Macroexamination

Macro examination is principally used for checking the quality of welds. A cross section of welded material is polished and etched for examination.

Purpose of Test: A common macro test is weld cross section examination to reveal internal discontinuities, weld profile, weld passes and sequence, extent of penetration and the quality of weld. The macrostructural properties of a weld metal can then be used as a component of weld procedure qualification or welder qualification.

Usually, macro examinations are performed at less than 20x magnification.

Failure Investigation

Failure analysis is the process of collecting and analyzing data to determine the cause of a failure, The failure analysis process relies on collecting failed components for subsequent examination of the cause or causes of failure using a wide array of methods, especially microscopy and spectroscopy. Nondestructive testing (NDT) methods. Carrying out investigation & preparing analysis reports with photographic documentation, technical findings, discussion, conclusion and recommendations of materials. Hands-on experience with corrosion related failures of components from oil/ gas production and refinery industries.

Corrosion Testing & Evaluation

Hydrogen Induced Cracking Test (HIC)

HIC stands for hydrogen-induced cracking; it is related to hydrogen blistering. the following description of hydrogen blistering: ”The formation of subsurface planar cavities, called hydrogen blisters, in a metal resulting from excessive internal hydrogen pressure.

The individual hydrogen atoms within the metal gradually recombine to form hydrogen molecules, creating pressure from within the metal. This pressure can increase to levels where the metal has reduced ductility, toughness, and tensile strength, up to the point where it cracks open (hydrogen-induced cracking, or HIC)

Sulfide stress corrosion cracking Test method A (SSCC-NACE Tensile Test) & method B (Four Point Bend test).

Sulfide Stress Corrosion Cracking (SSCC) is a form of hydrogen embrittlement cracking which occurs when a susceptible material is exposed to a corrosive environment containing water and H2S at a critical level of applied or residual tensile stress.
