Positive Material Identification
Ensure the integrity of your pipelines and critical process equipment
Across the global oil and gas industry, considerable effort has been focused on preventing the release of highly hazardous chemicals and toxic substances. Fatal accidents and injuries, as well as leaks, premature pipe replacements, loss of property, and unplanned outages at refineries, chemical plants and gas processing facilities often can be traced back to equipment failures due to faulty or counterfeit metal building components, sulfidic corrosion of piping and equipment, or because piping is made from material that does not meet specifications.
Sulfidation (sulfidic) corrosion affects steel piping and equipment and continues to be a significant cause of leaks in the refining industry. American Petroleum Institute (API) 939C, “Guidelines for Avoiding Sulfidation (Sulfidic) Corrosion Failures in Oil Refineries,” recognizes implementing “Retrospective PMI into a Material Verification Program” (per API 578) as an inspection method to detect and track sulfidation corrosion. Learn how to use our analyzers for PMI material inspection to prevent sulfidation corrosion.
HF Alkylation is an increasingly central process in the refining industry for the production of petrochemical products. The proper selection, application and placement of the alloys within the process piping envelope is critical to avoid unexpected corrosion and deterioration of pressure equipment components. Case studies have shown that residual elements (REs) in carbon steel can contribute to accelerated HF corrosion, primarily elements Cr, Ni, Cu. Learn more about identifying REs in steel piping.
Flow-accelerated corrosion, or FAC, is a well-known source of problems in nuclear and fossil-fuel power plants. With industrial safety regulations becoming increasingly stringent, positive material identification (PMI) of alloys used throughout the plant is a necessity. Learn how our analyzers perform PMI material inspection for PMI in metal fabrication environments.
Elemental analysis for PMI of piping and equipment with Thermo Scientific Niton handheld X-ray fluorescence (XRF) analyzers offers an ideal solution for ensuring quality assurance of selected components and weld materials or monitoring the trace alloy content of carbon steel piping where sulfidation and HF corrosion are a concern.
- Inspect and analyze individual component materials at receiving inspection, in-process welding/fabrication and final inspection check points
- Rapidly verify alloys in seconds
- Recover lost material traceability
- Isolate finished welds to validate filler material composition and dilution rates
- Confirm the integrity of process piping, valves, and reaction vessels.
See why Niton XRF analyzers are indispensible tools for performing PMI material inspection of piping and equipment.
