Pressure Vessel Steel Plates

Product Details:

HIC (Hydrogen Induced Cracking) is the result of a corrosive reaction between carbon steel and hydrogen sulphide. Wet hydrogen sulphide (H2S) cracking in steel has been a problem in petroleum refining and upstream oil and gas processing since the 1950s. Working conditions where wet H2S prevails are often described as sour service conditions and the term sour gas can be also be used in this context. As more fields rich in H2S are exploited, and this is increasingly the case, the problem is increasingly significant for equipment fabricated in potentially sensitive carbon-manganese (C-Mn) steels.

Steel in contact with water containing H2S will corrode producing hydrogen at its surface. H2S not only inhibits the formation of hydrogen gas, so reducing the opportunity for it to escape, but promotes its absorption in to the steel. At typical working temperatures below 200 degrees Celsius hydrogen atoms can become trapped causing embrittlement and ultimately cracking.

The use of steel pressure vessels in industries such as oil and gas processing requires a robust steel which is resilient to the long term corrosive effects of hydrogen sulphide in sour service applications. In order to provide better H2S resistance the properties of C-Mn steels have been progressively developed to improve chemistry, cleanliness, homogeneity, and microstructure.

Triton Alloys  provides a complete range of plate tested for its resistance to hydrogen induced cracking (HIC) in wet H2S (sour service) environments. The plate is manufactured by Industeel (part of the Arcelor Mittal Group) & by ISD HUTA, Poland and is guaranteed by them to have the following minimum properties:

• 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.We are able to offer plates to ASME / ASTM SA / A 516 Grades 60/65/70.
