Can you conduct corrosion testing on oil tubes of N-80 grade carbon steel material as per API 5CT? We would need samples from both good and affected portions of the tubes with a minimum of 2 feet in length. Also take care that these tubes are sent without cleaning because we need to analyze Corrosion products deposited on these tubes. If possible you may send additional packet of corrosion products that you may have collected from various tubes also. Please also send complete details of layout of tubes, history of failures and also samples of soil where these tubes are laid. We would need about 4 weeks time to complete the job. We are also prepared to carryout certain accelerated corrosion test in simulated conditions and study the behavior of your materials. Also certain standard NACE (National Association of Corrosion Engineers) that such as HIC & SSCC can be performed. We can also study the effect of certain impurities in metals and carryout EDAX and SEM analysis to evaluate corrosion mechanism.

Can you comment upon the corrosion levels in the Arabian Sea? TCR has strong experience in looking at marine corrosion in Arabian Sea. We have observed strong levels of corrosion on different types of stainless steels and copper parts that are part of shipping or offshore refinery. There are certain tests to verify the cause whether it is due to problem in your material or due to external cause. We can also find extent of damage and give you recommendations for remedies. We have seen MIC (microbiological Induced corrosion), and corrosion due to sour gas. We will need the actual samples send to our laboratory. Once the samples and any associated related data is with us we will provide you the quotation and actual time frame for the investigation.
