The Crack Thickness rate (CTR) HIC plate

The Crack Thickness rate (CTR) to one of evaluate HIC result way. According to NACE TM0284, The CTR result should be less 1.5%. The result is more less, The steel plate HIC result is more better.

According to NACE TM0248-2003, The testing solution is solution A that is 5%Nacl+0.5%HCA solution, and the initial PH value is 3.0, and be saturated by H2S.

The Test results of HIC are evaluated by requirement of TM0284-2003, The Crack Sensitivity rate (CSR), The Crack Length Rate (CLR) and the Crack Thickness rate (CTR) should be evaluated.

Crack Length Ratio (CLR) less than 5 %

Crack Thickness Ratio (CTR) less than 1.5%

Crack Sensitivity Ratio (CSR) less than 0.5%

The plate is tested to NACE TM 0284-03 Solution A and certified to EN 10204 3.2 (Lloyds). It is compatible with many of the world’s most stringent proprietary specifications including Petrobras N1706, Saudi Aramco 01-SAMSS-016, EEMUA 179, Axens IN-43, Shell MESC 74/125, and Shell DEP 31.22.10.32.
