Caltech Engineering Services manufactures hydrogen induced cracking testing apparatus ( HIC test ) to test and accurately determine the hydrogen induced cracking over exposed test specimens as per NACE standards requirements. HIC testing is recommended to evaluate the resistance of pipeline and pressure vessel plate steels to hydrogen induced cracking corrosion caused by hydrogen absorption from aqueous sulfide corrosion. Unstressed test specimens are exposed to a solution at temperature of 25deg cent with continuous H2S gas flow. The test specimens are finally removed and evaluated. Test specimens determine susceptibility of metals in H2S service. HIC testing apparatus meet requirements of ASTM / NACE Standard TM0284 and suitable to test material as per requirements of NACE MR0175.
