Following project 307 (Literature search and review of DSS at Short Term Elevated Temperatures), and Project 364 (Duplex Stainless Steels at Elevated Temperatures), additional work is needed to evaluate the effects of short term elevated temperatures on DSS welds and HAZ. This follow up project will evaluate an array of 2205 welds after short term exposures at elevated temperatures.

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 ...

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 is to conduct an experimental evaluation of this alloy following aging in a process environment to determine remaining utility for further plant service.
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 ...

Guidelines for evaluating equipment used in manufacturing of chemicals used in the high purity industry.
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. ...
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.
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.
The measurement of the mechanical properties of in-service metallic materials are important to obtain to determine the condition, to calculate remaining life and conduct fitness for service studies. Most methods for determining toughness and creep resistance are destructive and based on Charpy Impact Tests, fracture mechanics based CTOD (crack tip opening displacement) tests, and creep tests performed on standardized test pieces. The test pieces used for these types of tests must meet precise dimensional ...
The objective of this project is to identify corrosion data for aqueous lithium halide systems useful for CPI processes that is not available in the literature. Laboratory corrosion tests will be funded to create the needed data for use by MTI members.
New bio-oil products are now being produced commercially. The processes for producing bio oil can be corrosive, and alloy corrosion data for the new bio oil fuels is not available. There is interest in this topic and a new potential project was established to formulate a project on this topic.
Provide the industry with a comprehensive, introductory and overview book on ceramics and refractories for the Chemical Process Industry (CPI). A book will be written on new design and construction, repairs and inspections for all types of ceramic materials including acid brick, carbon brick, castables, ceramic fiber, graphite, high temp refractory, rammed materials, anchor, linings and ferrule materials. Installation and Inspection will also be covered. Each topic will be given approximately ...
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.
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.
Produce a catalogue of a variety of NDE responses (ToFD, ,PAUT, TFM/FMC) with corresponding metallographic characterization of carbon steel and carbon 1/2 moly HTHA specimens. Focus will be on incipient damage and HTHA with inclusions ad weld defects and other inclusions.
