Five Keys to a Cost-Effective Repair/Modification Package for Tanks-Vessels-Piping

: Process: Does the repair change the process chemistries, physics (fluid phase), and thermo-hydraulics (flow rates, pressures, temperatures)? Does the modification change the control room indications and the operating envelopes? Material: Are the selected metallic materials (base metal and welds) and non-metallic materials (gaskets, packings, etc.) compatible with the existing materials, with the environment, and […]

Reduced Toughness Properties of Some Modern Carbon Steels Create Brittle Fracture Risk

Changes in steelmaking practice are reported to be causing some carbon steel piping components that are assumed by ASME Codes to behave in a ductile manner at ambient temperatures, to behave instead in a brittle manner.  Barry Messer from Fluor made a presentation on this subject at the Spring 2016 meeting of the ASME B31.3, […]
