IMR Materials Testing Technical Blog


IMR provides testing for oil and gas production and transmission operators to keep the industrialized world’s fuel flowing.. We offer a variety of chemical analysismetallurgical testing, mechanical testing, and corrosion testing services. In the event of failure, we perform cause determination analysis, as well as solutions to prevent recurrence.

IMR’s corrosion experts can identify corrodents and other variables that are responsible for corrosion attack. We have a history of addressing complicated corrosion issues, including stress corrosion cracking, dezincification, pitting corrosion and many other mechanisms.

IMR Test Labs have the expert staff and knowledge to provide material verification and R&D testing for metals, polymers, coatings and contaminants. We have earned a wide range of accreditations and our quality system has passed some of the most stringent audits.  All of our labs operate under the same strict quality system to ensure that the results you get are accurate, as well as fast.


The potential for dramatic and costly pipeline failures continues to be a top concern for regulatory agencies, pipeline operators and energy providers.  In 2017, the Pipeline and Hazardous Materials Safety Administration (PHMSA) issued a final rule that mandates several preventative and documentation processes designed to standardize the measurement, testing and assessment of pipeline inspection procedures.

IMR Test Labs-Louisville is a well-equipped and experienced pipeline materials testing center.  We’ve helped several regional, national and international petro-chemical production and transmission companies answer questions specifically related to pipeline material properties.  IMR has the mechanical, chemistry and metallurgical expertise to help operators apply the test data to decisions about future pipeline maintenance plans.  Our clear, concise reports contain the critical analyses to insure compliance with 49CFR, Part 192- the requirement that operators have full knowledge of assets operating in High Consequence Areas (HCA).

For more information on testing your pipeline assets to be in compliance with the PHMSA, click here.

Our facilities provide extensive coatings evaluation services including adhesion, coating shear fatigue, corrosion simulation and metallurgical evaluations.  With AWS CWI’s at all US locations we can provide weld qualification and testing packages to meet your needs.
