Be the first person to recommend this.
TRACK: Materials for Harsh Environments Metal dusting is a damage mechanism that occurs under very specific process conditions, so it is not widespread, but when it occurs it is often at catastrophic rates. Also, although extensive past literature has been published providing laboratory test data, each data set is specific to a set of conditions and they are not easily compared with one another. Often the resistant alloys vary based on the test conditions. This paper builds on past papers by compiling case histories, listing numerous past published literature with test programs, and detailing the current inadequate methods (and subtle caveats) for predicting ...

Quit Being So Sensitive – An Investigation of Sensitization Behavior of Alloy 600 During Welding

posted 9 days ago
Be the first person to recommend this.
TRACK: Failures/Failure Analysis Sensitization is a known phenomenon that occurs in Alloy 600 in operating temperature ranges of 1000°F to 1800°F due to the precipitation of chromium carbides (Cr7C3 and Cr23C6). The resultant grain-boundary precipitation of these chromium carbides can result in increased susceptibility to intergranular attack when exposed to corrosive media. In this study, the effects of material characteristics (carbon content) and weld processing parameters (heat input, maximum interpass temperature) on Alloy 600’s microstructure and corrosion resistance via ASTM G28A are investigated. Additionally, mitigation techniques (lab-performed post-weld ...

Mechanical Integrity of High Temperature Steam Methane Reformer Furnace Tubes

posted 30 days ago
Be the first person to recommend this.
TRACK: Materials for Harsh Environments As the primary source for bulk hydrogen production worldwide, steam methane reformers (SMRs) require heat resistant materials to withstand their challenging continuous operating conditions that exceed 815°C. Good high temperature creep performance is a requirement for materials used in such conditions and HP-modified, HP-microalloyed grades of Ni-based alloys are commercially employed for such applications. However, prolonged exposure to high temperatures promotes changes to the metastable microstructure of these alloys and an understanding of the effects of such transformations on long-term creep performance of these ...

Long-term metal dustings experiments and ASME Code Case for New Alloy N06699

posted 12-18-2025
Be the first person to recommend this.
TRACK: Emerging Technologies The newly developed Ni-based alloy N06699 has been designed for high-temperature applications in the chemical and petrochemical industry, exhibiting an excellent resistance under metal dusting conditions due to the high Cr (approx. 30 wt.%) and Al (approx. 2 wt.%) content and the reduced Fe content (< 2.5 wt.%). The corrosion performance in these aggressive conditions has been proven in several metal dusting experiments, not only for the base material (plate and bar) but also for welded and printed samples from powder via PBF-LB/M. Recently, long-term experiments with a duration of up to 10,000 h verified again the outstanding ...

Understanding Reaction Forces in Hinged and Gimbal Expansion Joints

posted 11-24-2025
Be the first person to recommend this.
TRACK: Safety/Reliability Industry standards like ASME B31.3 for Process Piping and NEMA SM23 for mechanical equipment establish guidelines for stress limits and allowable nozzle loads to ensure system reliability. Expansion joints play a vital role in piping systems by absorbing thermal expansion and reducing mechanical stress, providing necessary pipe flexibility and ensuring compliance with these limits. Without them, process piping and equipment such as steam turbines and turbo-expanders could be exposed to excessive forces, leading to irreversible damage and premature failure. Metallic expansion joints are designed according to the Expansion Joint Manufacturers ...

Evaluation of New Glass Lining Repair Technique

posted 09-09-2025
Be the first person to recommend this.
Introduction Glass-lined steel (GLS) offers benefits such as excellent corrosion resistance to a broad range of chemicals, product purity, a non-stick surface, and lower purchasing costs compared to nickel alloy or reactive metals. Unlike thermoplastic-lined options, the glass lining will not permeate and can handle full vacuum. However, glass is susceptible to mechanical damage, has limited allowable bolt load and gasket types for its flange connections, and any lining damage can only be covered, not truly repaired. Due to the breadth of its chemical resistance, GLS can shine in reactor applications where the chemistry can vary greatly during its residence ...

Development of a CUI Estimation Model Based on Actual CUI Inspection Data

posted 08-12-2025
Be the first person to recommend this.
Abstract Corrosion under insulation (CUI) is a common and safety-critical type of corrosion in aged chemical plants. Currently, CUI inspections are mainly carried out by setting up scaffolding and removing the thermal insulation because there is no efficient and cost-effective nondestructive inspection method for CUI. The cost is enormous, and in many cases, corrosion may not be present even after the insulation is removed for inspection. Therefore, it is important to properly estimate the areas to be inspected. Several CUI estimation methods have been proposed, but the accuracy is not sufficiently high. CUI inspections have been conducted for many years, on ...
