NACE Testing

National Association of Corrosion Engineers 

The primary function of the NACE Lab is testing pipe to meet the API requirements for sour service pipe sold as oil country tubular goods (OCTG). We perform the testing that requires Hydrogen Sulfide exposure. We follow two methods NACE TM0177 (Tensile, Bent Beam, and DCB) and NACE TM0284 (HIC). 

H2S corrosion process occurs during drilling for oil and natural gas, in the petrochemical industry, oil refineries, and even in the food processing industries. Laboratory investigation of corrosion and corrosion resistance can help you establish material selection under the prevailing conditions of use. Corrosion depends upon the environment, the type of concentration of pollutants, temperature, pressure, and dynamic activity. 

NACE testing can be accomplished on steel bars, pipe, or sheet. Preparation of testing may be through a section of bar or pipe. Presently, we test materials without corrosion inhibitors such as paint or WD40, though we plan such testing in the future. 

Samples are subjected to a prescribed load in a corrosive solution of salt water saturated with H2S; designed to mimic field conditions found in actual use. 

Typical testing runs from five days to 30 days, based on the test selected. We can vary solution chemistry, gas concentration, or the testing time to meet your requirements. Results are reported for each group of tests and include the sample information, test conditions, and final result.
