There are numerous standard ASTM test methods for determining the relative resistance of materials or surface treatments to impingement, dry sliding wear, and wet reciprocating wear, however, there is no established correlation between a material’s mechanical properties and its wear resistance. The relationship between such wear tests and actual wear performance in equipment is unclear. The objective of this project is to develop approaches to predict wear rates for a range of materials frequently ...

Produce a text providing introductory discussions on high temperature ceramic materials (excluding electronics) in MTI Member facilities. Include general description, common installation methods, inspection recommendations applicable during installation and ...
The project proposes an investigation of stainless steels corrosion resistance to Pitting, Crevice and SCC resistance in temperatures above 90oC (194oF) and low chloride amounts. The aim is to complete the existing engineering diagrams defining the temperature-chloride content boundaries for these corrosion mechanisms.
Develop a Guideline that covers the basic degradation mechanism that can damage equipment and piping during plant construction, pre-commissioning. List the mitigation and prevention steps, be aware that these have changed with module fabrication in low cost countries and ban on many corrosion inhibitors due to environmental concerns. The MTI guideline should become an “industry standard” that can be shared with non-materials/corrosion engineers to avoid MIC failures. It should describe cases and ...
Create a guideline for failure mechanisms in the pulp and paper industry. This reference will include generic pulp and paper unit Process Flow Diagrams with the applicable damage mechanisms for each system in the process. Specifically, it will include the following mechanisms which are not available elsewhere: - Continuous Digester Caustic Stress Corrosion Cracking inspection techniques and repairs - Sulfur Stress Corrosion Cracking (Turpentine Systems) - Stress Assisted Corrosion - Recovery ...
The objective of this project is to produce an atlas for alloys C-22, C-2000, 59 and 686 microstructures that clearly identifies the phases that occur in the alloy. The thermo-mechanical processing and welding that produced the microstructure will be properly documented with each case. The microstructural cases will be correlated with published or computer generated TTT data to explain the presence of each phase.
No tool exist for predicting the corrosivity in the aqueous streams in renewable fuel processing units. The aqueous phase contains a combination of chemicals (CO, CO2, H2S, NH3 and HCl) which are all outside of the existing available models. The goal is to better understand the limits for corrosion resistant alloys under the aqueous conditions present in renewable fuel processing units
The project consists of data collection from literature failure reports and member company surveys stating as much as feasible the pertinent failure conditions such as: Metallurgy, Operating Temperature (range), Time to cracking, Wall thickness, Microstructure that cracked (Weld/HAZ/Base/grain size/heat treatment condition at fabrication/repaired or not/etc), Weld geometry and technique, Estimate of % of cold work, Repair welded (before or after PWHT/service), and any other factors. This information ...
Half pipe reactors are used frequently in petroleum refining and chemical processing plants. Due to the characteristics of their construction this reactor design can develop stress corrosion cracking (SCC) under the half pipe often due to the coolant chemistry. SCC causes leaks and can result in decommissioning with extremely long replacement times. This project will conduct a search of the literature on the topic and include a test program to identify the best options for prevention and repa ...
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. The project objective is to use this effort to validate the qualification for materials used in fabrication of BVP equipment. ...
Develop standard, critical and operational IOW templates/guidance for the most common chemical plants. The common chemical process IOW templates will be a MTI stand-alone product and/or serve as an addendum to API 584.
24/7 online access where members can ask technical questions and receive reliable answers from leading member industry experts around the globe. The MTI Forum often saves MTI members time, money and sometimes lives.

Determine what is the maximum rate of temperature change without damage to the lining system via FEA modeling. There is minimum adhesion values provided in various publications and standards. ASME RTP-1 Mandatory Appendix M-12 provides values in M12B-614.4 for thermoplastic linings on FRP substrates. Adhesion strength testing on carbon steel in accordance with ASTM D903 and D1781. These values shall be the basis to determine onset of failure using FEA modeling.

The book, “MTI MANUAL NO. 8 FRACTURE CONTROL FOR THE CHEMICAL PROCESS INDUSTRIES” by D. Broek was published in 1983. It is a very instructive book aimed at providing a solid understanding and appreciation of the basics of fracture mechanics and its use to a technical audience not expert in this technology. Many technical developments in the use of fracture mechanics applied to process equipment have occurred in the 40 years since the 1983 publication. This book is of high quality and explains ...

An Alloy 625 vessel with heads, piping, welds, and flanges that was operated at the lower temperature regime of the TTT curve with exposure of about 40,000 hours has been removed from service and is available for metallurgical analysis. The project objective is to create an addendum to the Atlas of Microstructures for 625 with analysis of this material that would document the microstructure of this alloy with actual long term service exposure at moderate temperature.
The project objective is to investigate the relationship between various shot peening parameters on the galling and corrosion resistance of select nickel-based alloys.
ASSET (Alloy Selection System for Elevated Temperature) is a powerful high temperature corrosion prediction program that was developed in a JIP with MTI, Shell and others with DOE funding in 2000-2005. Action is required to update the software and improve its functionalities so that it can continue to be of value to MTI members.
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 that will be useful for predicting ...
