Publication number: 20180217104Abstract: Embodiments relate generally to systems and methods for determining a toughness value for a material of a metal part, wherein the method comprises detecting a texture of a carbon steel material using an ultrasonic microscopy unit, wherein the ultrasonic microscopy unit uses one or more waveforms including at least one of straight beam, phased array, shear wave, and time-of-flight diffraction (TOFD); determining elemental analysis of the carbon steel material; combining the texture with the elemental analysis to generate a toughness value for the steel; comparing the generated toughness value with a standard curve, wherein when the toughness value falls below the curve, the carbon steel material comprises an acceptable toughness, and when the toughness value falls above the curve, the carbon steel material comprises an unacceptable toughness.Type: ApplicationFiled: July 22, 2016Publication date: August 2, 2018Inventor: Barry Messer

Patent number: 8967451Abstract: Contemplated systems and methods significantly improve friction stir welding of hard metals and particularly steel and stainless steel. Among other factors, the inventors found that high transverse velocity of the tool is critical to obtain predictable and desirable weld quality, which is preferably achieved in such materials by minimizing spindle run out. Moreover, the transverse and angular velocities are preferably selected such as to achieve a temperature in the weld that is below the phase change temperature and/or the solid state transformation point of the materials.Type: GrantFiled: July 9, 2009Date of Patent: March 3, 2015Assignee: Fluor Technologies CorporationInventors: Barry Messer, Dennis Maki

Patent number: 8695868Abstract: Devices and methods of welding dissimilar materials are contemplated in which an adaptor is used in an intermediate position between the dissimilar materials. Most preferred adaptors are manufactured by friction stir welding from two dissimilar materials that are identical or similar to the dissimilar materials to be welded together. Therefore, coupling of dissimilar materials in the field via the adaptors is greatly simplified as conventional welding methods can now be employed.Type: GrantFiled: August 27, 2007Date of Patent: April 15, 2014Assignee: Fluor Technologies CorporationInventors: Barry Messer, Shawn Seitz

Patent number: 8118994Abstract: Naphthenic acid corrosivity of hydrocarbon feedstocks is correlated with the chemical composition of naphthenic acids, and especially with a ratio between an alpha fraction and a beta fraction of naphthenic acids. Contemplated plants, configurations, and methods are directed to reducing naphthenic acid corrosivity of hydrocarbon feedstocks by increasing the beta fraction over the alpha fraction.Type: GrantFiled: July 1, 2004Date of Patent: February 21, 2012Assignee: Fluor Technologies CorporationInventors: Barry Messer, Bart Tarleton, Michael Beaton

Patent number: 7837810Abstract: Thermo-mechanical properties of welds in stainless steel is substantially improved by the implementation of a post weld heat treatment that illiminates sigma phase in the heat treated zone and favors niobium carbonitride precipitate formation in a desirable size range. In most cases, post weld heat treated material can be employed in pressurized devices at temperatures exceeding 550° C., which is currently regarded the upper safe temperature limit, and material according to the inventive subject matter was tested at temperature of up to 850° C. without reheat cracking.Type: GrantFiled: June 16, 2004Date of Patent: November 23, 2010Assignee: Fluor Technologies CorporationInventors: Barry Messer, Terrell T. Phillips, Vasile Oprea

Patent number: 7784347Abstract: Contemplated configurations and methods are directed to non-destructive ultrasound testing of stainless steel materials, and especially materials in a difficult-to-reach position, in which a phased array probe is operated using longitudinal waves, wherein the probe is further operated at an angle that provides substantially complete ultrasound coverage when the beam angle is modified.Type: GrantFiled: May 17, 2005Date of Patent: August 31, 2010Assignee: Fluor Technologies CorporationInventors: Barry Messer, Jose R. Fuentes

Publication number: 20090212023Abstract: Contemplated methods for welding stainless steel substantially improve welding speed and quality. Most typically, such attributes are achieved by welding a root pass using GMAW-Sm to thereby depositing a root, welding a hot pass using GMAW-P to thereby deposit additional weld metal onto the root, and by welding at least one of a fill pass and a cap pass using at least one of GMAW-P and FCAW.Type: ApplicationFiled: May 17, 2005Publication date: August 27, 2009Applicant: FLUOR TECHNOLOGIES CORPORATIONInventors: Barry Messer, Shawn Seitz, Kenneth E.

Patent number: 7255007Abstract: An ultrasound test apparatus for polymeric materials (e.g., plastic pipes) includes a low-absorption housing that at least partially encloses an ultrasound transducer, wherein the transducer emits a low frequency wide angle ultrasound beam with a narrow bandwidth. In especially preferred configurations and methods, the apparatus will detect flaws in polymeric pipes, and especially in welds or stressed zones of such pipes, wherein defects of less than 4% of the wall thickness (up to 4 inches) are detected. Further disclosed are configurations and methods for nondestructive detection of lack-of-fusion defects in polymeric pipes.Type: GrantFiled: July 24, 2003Date of Patent: August 14, 2007Assignee: Fluor Technologies CorporationInventors: Barry Messer, Matthew Allen Russell Yarmuch
