Case Study on Reliability of Modern Materials: Fluoropolymer Lined Engineered Structural Composite Piping Systems

posted 6 days ago
Be the first person to recommend this.
TRACK: Safety/Reliability Maintaining a competitive advantage in emerging and growth markets like minerals, desalination, data centers, semiconductors, specialty chemicals, chlor-alkali, and steel requires plant operators and engineering firms to be educated on modern materials. Corrosive environments demand advanced piping materials to cut lifecycle costs and boost uptime. New piping solutions face hurdles such as lack of testing standards, limited awareness, and knowledge gaps among engineers, especially those focused only on metallic systems. Fluoropolymer-lined engineered structural composite piping will be used as a case study to illustrate how these ...

Mechanical Integrity of High Temperature Steam Methane Reformer Furnace Tubes

posted 8 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 13 days ago
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 ...

posted 14 days ago
Be the first person to recommend this.
TRACK: Non-Metallics Rubber lining remains one of the most proven solutions for corrosion resistance in chemical processing environments, yet its effectiveness hinges on much more than material selection. This presentation will explore the critical success factors of rubber lining systems—from substrate preparation and atmospheric curing techniques to material handling and field installation practices—particularly for tanks, piping, and complex geometries in high-risk service conditions. Drawing from field-proven case studies, this session will examine challenges encountered with large-diameter tanks and vessels that cannot be autoclave-cured, and where ...

Graphitic Corrosion of Cast Iron Piping: A Background and Practical Approach to Identification in Underground Installations

posted 14 days ago
Be the first person to recommend this.
TRACK: Failure/Failure Analysis Cast iron pipes are often laid underground and forgotten because, usually, nothing happens to them for decades. Over the past few years, several sections of cast and ductile iron pipe have been sent to my lab for failure analysis having all met the same fate: Graphitic corrosion caused by acidic soil (usually associated with salt for melting ice on roads and walkways) after ~40 years of service. This presentation offers a background into graphitic corrosion of cast and ductile iron pipes, including metallographic samples from field failures, and a discussion on the problems it has caused. A practical approach to identifying ...

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 ...

BY: BENJAMIN A. SPRENGARD, PE, MSC, CWI, ASNT III ENERFAB PROCESS SOLUTIONS Executive Summary Alloy 800H is a high-performance, nickel-iron-chromium alloy that is specifically designed for high-temperature service. Its composition and properties make it suitable for a range of demanding applications, including pressure vessels, heat exchangers, and other process components. However, 800H has an inherent susceptibility to solidification cracking during fabrication due to its larger grain structure and alloying additions. In this case study, Alloy 800H (UNS N08810) forgings were welded with NiCr-3 filler metal. Microfissures were observed with dye penetrant ...

N ickel alloys are used by chemical processing industries to handle highly corrosive chemicals in extreme conditions and to meet the challenging environmental requirements. The previous Materials Technology Institute (MTI) Project 269, completed in 2017, had built up a corrosion rate database for five grades of the most commonly used nickel alloys inclusive of Alloy 276 (N10276), Alloy 22 (N06022), Alloy 625 (N06625), Alloy 825 (N08825), and Alloy 600 (N06600). The documentation from Project 269 has proven extremely useful to many MTI members, and a successive phase 2 project, MTI Project 367, was initiated to extend the database for more grades of nickel ...
