Summary of Expertise: Listed with other top experts in: 
Expert is a member of the Main Committee of the ASME Boiler and Pressure Vessel Code, the Subcommittee on Pressure Vessels (Section VIII), the Subcommittee on Design, the Subgroup on Design for Section VIII He is a member of the Subgroup on Toughness for the Subcommittee on Properties of Materials. He is a member of the Special Working Group on Bolted Flange Joints that reports to the Subcommittee on Design. He is a member of the newly formed Main Committee for the Post-Construction Code and its Subcommittee on Inspection Planning. He is Chairman of the new subcommittee XII formed in February, 1997 to develop a code for DOT-regulated transport tanks such as railway tank cars and highway chemical tankers. Expert has also developed expertise in foreign boiler and pressure vessel codes, especially German pressure vessel codes.

Expert has designed, analyzed, and performed failure analysis of autoclaves. The design was according to the rules of the ASME Boiler and Pressure Vessel Codes.


Expert has developed rules for design to prevent buckling for non-circular pressure vessels. He currently designs vessels, silos, hoppers, and steel structures to prevent buckling.


Part of Expert's everyday work involves the evaluation of deformations in piping, vessels, and structures.

deformation analysis

Expert's firm specializes in finite element analysis using the ANSYS and ALGOR programs.

finite element analysis

Expert uses fracture mechanics on a continuous basis in his design evaluation and failure analysis. His ASME Code Committee work involves devising toughness rules for the code based upon fracture mechanics principles.

mechanical fatigue

Expert has experience in controlling the escape of hazardous chemicals from piping, pumps, valves, and vessels. He is the past Chair for the ASME Code Committee developing design rules for gasketed joints in piping.

fugitive emission process

Expert has recently evaluated the failure of two high-temperature vessels operating at 1350F and 900F and provided redesign services for these vessels. In the 1970s, Expert was one of the developers of the elevated temperature design rules now found in the ASME Boiler and Pressure Vessel Code.

Expert performs many failure analyses of metal or composite pressure vessels and other mechanical equipment using the services of local materials and metallurgical labs. A recent example involved evaluating the failed weldment on a stainless steel bulb used in a temperature sensing device.

materials failure analysis

Expert is President of Pressure Sciences Incorporated, which he founded in January, 1989. In over seventeen years of operation of Pressure Sciences, Expert has performed a diverse series of engineering projects. Some of these are listed below.

For the Commonwealth of Pennsylvania, he evaluated the public and environmental safety of a 20 million gallon refrigerated liquefied propane gas storage facility.

He evaluated over three hundred riveted and welded API 12A and API 650 oil storage tanks located at a Mobil Oil refinery to the criteria of API Standard 653 using data obtained by inspectors. He developed an engineering specification, suitable for computer programming, for Mobil to evaluate riveted and welded oil storage tanks according to the requirements of API Standard 653.

He implemented baseline inspections and evaluations of pressure vessels, piping and storage tanks for several chemical processing plants to help them to comply with the Mechanical Integrity portions of the OSHA Process Safety Requirements. He developed protocols for sampling methods and for information management to effect substantial cost savings.
