Hydrogen induced cracking test apparatus is rectangular provided with ready to use connections fittings. HIC test apparatus is supplied with essential spares for uninterrupted long term testing. These specimen are machined with thickness of 5-30 mm, width 20 mm, and length of 100 mm is suitable for testing as per the NACE Standard. Hydrogen induced cracking test instrument is supplied with standard size of 12" (L) x 12" (W) x 9" (H). It is provided with specially made rack to keep the samples with minimum surface contact and all the specimens can be viewed during the test period easily.
HIC test apparatus is suitable for standard environment chamber is machined from clear, durable perspect / acrylic to permit instant visual observation of the specimen at all times. Glass with acrylic is also available at option of user. O-ring seals are provided to prevent any leakages from test apparatus. Individual test apparatus are tested with Hydro Test of Air before dispatch. Each HIC testing apparatus has one inlet, one outlet and one plug to remove test solution or conduct potassium idometric test as per the standard to verify concentration of test solution.
What is hydrogen induced cracking? Refer NACE Standard TM0284
All the test apparatuses are manufactured to provide interchangeable connections and fittings. It complies with requirements of TM0284. Purpose of HIC test procedure is to study hydrogen induced cracking mechanism. HIC test apparatus is suitable to use NACE TM0284 specified Solution A or Solution B. Solution A is acidified brine. Solution B is simulated seawater prepared in accordance with ASTM D1141. In either case, H2S is bubbled through the solution constantly throughout the test period. NACE TM0284 specifies test duration of 96 hours. The test requires evaluation of pH values of the test solution before exposure and after the exposure. HIC test specimens are cut into sections and examined under a microscope for hydrogen-induced corrosion 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) as per the NACE Standard. We are also able to provide spares, HIC test procedures of all the items within shortest time.
Hydrogen induced cracking corrosion testing (HIC Test) can be made easy by using Caltech's HIC Testing Apparatus.
