Corrosion Detection and Testing at TCR-Kuwait laboratory undertakes wide range of corrosion and stress corrosion test per ASTM, NACE or BIS. Tests can also be custom tailored to meet an individual client´s requirements.
A wide variety of corrosion related tests can be undertaken at TCR-Kuwait Engineering Services in Kuwait to determine weight loss corrosion, intergranular attack, pitting corrosion, corrosion fatigue, stress corrosion cracking, sulfide stress cracking, and hydrogen-induced cracking.
Corrosion Experts and Strong Metallurgy Team
Senior staff members with specific industry expertise cover a variety of corrosion problems that are encountered in industries such as oil and gas production, oil and gas transmission, energy conversion systems, and nuclear power systems.

Intergranular corrosion in stainless steels may result from precipitation of carbides, nitrides or intermetallic phases. Only in the most highly oxidizing solutions can intergranular attack be caused by intermetallic phases. When a test is to be restricted to carbides, in a material containing nitrides or intermetallic phases, a less oxidizing solution is chosen. To conduct these tests, the corrosion team at TCR-Kuwait carefully chooses a method which is suitable for the steel grade and grain boundary composition to be tested.
Salt Spray (Neutral / Fog), ASTM B117
A number of samples can be tested at once depending upon their size for salt spray corrosion testing of inorganic and organic coatings, especially where such tests are used for material or product specifications. Salt Spray testing is a tool for evaluation the uniformity of thickness and degree of porosity of metallic and nonmetallic protective coatings.
Pitting Corrosion Test, ASTM G48 Method B Specification
ASTM G48 Method B, Ferric Chloride Test involves exposing a specimen to a highly oxidizing acid chloride environment. The importance of ASTM G48 Method B, Ferric Chloride Test is to be able to determine the extent of pitting, either in a service application where it is necessary to predict the remaining life in a metal structure, or in laboratory test programs that are used to select the most pitting-resistant materials for service. We can also undertake Piting Corrosion test as per ASTM A 923 Method C.
Corrosion test as per ASTM G 35 specification
The polythionic acid (sulfurous acid and hydrogen sulfide) environment provides a way of evaluating the resistance of stainless steels and related alloys to inter granular stress corrosion cracking. This practice can be applied to wrought products, castings, weld metal of stainless steels or other materials to be used in environments containing sulfur or sulfides.
Hydrogen-Induced Cracking (HIC) Test, NACE TM0284
HIC Test evaluates the resistance of pipeline and pressure vessel plate steels to Hydrogen Inducted Cracking caused by hydrogen absorption from aqueous sulfide corrosion. An unstressed test specimen is exposed to a solution at ambient temperature and pressure and after a specified time, the test specimen is removed and evaluated.
TCR-Kuwait issues a detailed written report upon completion of each test. Each report includes a description of the test sample that was received, the test procedure that was used, and the pH values of the test solution before exposure and after the exposure. The test bars are cut into sections and examined under a microscope for hydrogen-induced cracks. The dimensions of any such cracks are recorded and used to compute the values in percentage for Crack Length Ratio (CLR), Crack Thickness Ratio (CTR) and Crack Sensitivity Ratio (CSR).
Sulfide Stress Corrosion Cracking (SSCC), NACE TM 0177
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.
TCR-Kuwait SSCC test completion report includes a description of the test sample that was received and of the test procedure that was used, the pH values of the test solution before and after the exposure, the results of the hardness test performed on the test specimen and a statement declaring the results of each test.
