Robert A. Leishear, PhD, P. E. is a Fellow of the American Society of Mechanical Engineers (ASME), a Consulting Engineer for Leishear Engineering, LLC, a licensed Professional Engineer in South Carolina, A Journeyman Sheet Metal Mechanic, a NACE Senior Internal Corrosion Technologist, and a member of several ASME international piping and pressure vessel committees. He has traveled far from his days of walking on four inch I-beams,  500 feet in the air without fall protection, to his present position as a Doctor in Engineering. His wide range of skills developed along the way can be used as tools to fix your piping system, explosion, and fluid flow problems to increase the success of your business.

Dr. Leishear earned his Bachelor's degree in Mechanical Engineering from Johns-Hopkins University, parallel to completing indenture for a Sheet Metal Mechanic's apprenticeship and welding school. While employed at Savannah River Site (SRS ), he attended the University of South Carolina at night to earn his Masters and Doctoral degrees in Mechanical Engineering and has completed all of the classes required to earn a PhD in Nuclear Engineering. While completing graduate research, he completed over a hundred Savannah River Site nuclear facility process engineer classes, electrician training, and ASME piping and pressure vessel design classes. 

Across the US and overseas, he has also completed courses in International Nuclear Law, Radiology, and extensive training for nuclear reactor computer design codes for reactor core physics, thermal hydraulics, fluid transients, Fluent, Ansys Stuctural, and Autodyne. All in all, he has one of the the most extensive educations in the mechanical engineering industry.

Dr. Leishear's studies and accomplishments focused on fluid flow, piping design, vibrations, failure analysis, and fluid machinery, as well as explosions in piping systems. That is, his specialties are fluid, structural, and machinery dynamics, where he has worked as a research engineer for Savannah River National Laboratory, a Process and Plant Engineer for Savannah River Nuclear Solutions, and as a lead engineer for design, calibrations, compressors, mixing, pumps, and piping. In these positions, he earned tens of millions of dollars in cost savings, which are documented in his more than 80 publications. 

These publications include an ASME text book, magazine articles, conference papers, and Honors journal papers. He has also taught advanced engineering classes throughout the country for the American Society of Mechanical Engineers.

To capstone his troubleshooting successes, Dr. Leishear received several ASME awards for service, a dozen SRS corporate awards, and the Mensa Copper Black Award for Creativity for his research on explosions in nuclear facilities and offshore oil rigs. His future success can be your success as well.

A Trail of Successes

troubleshooting fluid systems: 

A Step beyond the edge of the impossible

I stop water main breaks, pipeline cracks and leaks, pump failures, compressor failures, and pipeline explosions. That is, engineering services are available to troubleshoot existing fluid system problems or to complete new designs. In particular, difficult and seemingly insoluble fluid flow problems, pipe failures, and machinery failures can be resolved. I have had the good fortune to earn an extensive engineering education and experience, which are coupled with an extensive hands-on technical background in the construction trades. My career has been dedicated to understanding all aspects of fluid machinery and fluid systems operations, as well as failure analysis of equipment and piping failures. At the risk of not sounding very humble, every engineering and scientific team project that I have ever led over the past thirty years was a success, regardless of complexity. In fact, I solved many industrial problems that were unsolved for decades. Success is not an accident, it is the natural outcome of hard work, tenacity, diligence, and doing what one believes to be right.
