Corrosion Data Collection for the Most Commonly Used Corrosion-Resistant ...  

MTI project 269-Corrosion Data of the Most Commonly Used Corrosion Resistant Nickel Alloys was successfully completed in December 2017. That MTI project was the first joint effort to collect, analyze, and publish corrosion data of nickel alloys from various major global suppliers. Five typical nickel alloys were selected for corrosion data collection, including Alloy C276, Alloy 22, Alloy 625, Alloy 825, and Alloy 600. The contractor of the project was Industrial Technology Research Institute (ITRI) ...

Glass Lining Repair Technique Evaluation (266)  

The objective of this project is to validate the robustness of this new repair technique for GLSE. Ideally the testing will simulate all known failure mechanisms for GLSE that could potentially apply to these patches. This project would perform mechanical and corrosion testing on glass lining bonded to steel. Testing could include: adhesion; strain line; spark; impact (external); impact (internal); abrasion; thermal; compressive; flexure; tensile; chemical; etc.

Investigation of Low Toughness of Carbon Steel Piping Components (318)  

The goal of this project is to determine the root cause of ubiquitous low-toughness-testing results on carbon steel piping components used in the CPI. Using data collected from member companies and third party suppliers of piping components, a statistical analysis will be completed to look for a relationship between low toughness of the carbon steel components and other properties. When a relationship is found, a project scope will be developed to complete material lab analysis of metal samples ...

Metal Additive Manufacturing Qualification for ASME BPVC (386)  

Additive Manufacturing (AM) provides designers the ability to build parts directly from computer-aided design (CAD) files. Metal AM technology is rapidly maturing and offers a range of benefits to reduce cost, schedule and increase performance of Boiler and Pressure Vessel (BPV) systems. The impact to the BPV industry has been limited by the availability of standards. Several American standard bodies are developing consensus-based standards. MTI has been invited to join a project developed by ...

CPI Equipment, Materials, and Corrosion Learning Modules (336)  

The purpose of this project is to create an in-person short course with an introduction to process industries corrosion. The goal of the course is aimed at introducing new engineers and other technical personal to corrosion, common types of process equipment, materials of construction, fabrication techniques, and codes and standards. It is meant to give the students basic information on corrosion and how it is prevented in the chemical process industry to augment on-the-job training as they start ...

Remaining Life Evaluation of Aged Alloy 20Cr32Ni Components (375)  

This project follows the completed project 356 which produced an analysis of the existing literature on this topic and guidance on an experimental plant to determine the remaining lifetime of components composed of Alloy 20Cr32Ni after aging at high process temperature. The objective of this project will be to conduct an experimental evaluation of this alloy following aging.in a process environment to determine remaining utility for further plant service.

Pressure Swing Adsorber (PSA) Vessels Structural Integrity and Fatigue ...  

PSA (pressure swing adsorption) pressure vessels are often used in the purification of hydrogen after syngas production. These vessels are manufactured from carbon steel and are welded in accordance to design codes and standards. Due to fluctuations in pressure, these vessels are usually affected by fatigue damage which can be accelerated due to exposure to hydrogen. The purpose of this project is to establish a relevant materials database for PSA steel in hydrogen.

PTFE Bellows Expansion joints Integrity (351)  

PTFE bellows expansion joints are routinely used in chemical plants. Typically they do not have a metallic housing the way other PTFE equipment and piping have. PTFE is not a structural material hence a housing is needed. Failures of them resulting in safety incidents have occurred resulting in lawsuits as well as banning their use in many companies. The project objective is to collect the state of the art information and create a guideline which promotes the safe and reliable use of them.. Of ...
