Carbonate Stress Cracking in Refinery Service (294)  

Alkaline Carbonate Stress Corrosion Cracking (ACSCC) continues to occur in non-stress relieved carbon steel assets that are used in refinery sour (H2S) water service. The parameters controlling ACSCC are not clearly understood and the test methodology to monitor and predict ACSCC has not been universally accepted.
The first goal of this project is to establish the precision of carbonate measurement with bench top techniques as compared to ionic models. The second goal is to perform stress corrosion cracking tests in modeled sour water environments and produce a fail/no-fail threshold for the environment.

Ceramics 102 Training (277)  

Specialized knowledge in refractory ceramics is a dying art. The industry is experiencing a loss of expertise due to the steady flow of retirees from an aging workforce. In addition, today’s materials science programs are becoming increasingly focused upon general materials. With less emphasis placed on specific classes of materials such as metals or ceramics, this leaves the upcoming generation of engineers without the training and knowledge needed as they move to the workforce. Most companies do not have the luxury of on-staff ceramic engineers and are becoming more dependent upon the refractory vendors and consultants to supply information and recommendations. This can be confusing and intimidating, especially for younger engineers. Often times these engineers are at a loss for how best to communicate their needs, and are left wondering after the job is complete whether they were provided the best solution.

Ceramics 201- Preventing Refractory Failures (340)  

Ceramics 201- Preventing Refractory Failures (formerly Ceramics 103) will be a half-day training session that will build on the foundations taught in the previous two Ceramics training courses. The focus will be on Case Studies of Ceramics and Refractory Failures, with images, learnings, and failure analysis techniques. Both thermal refractory and chemical resistant refractory will be covered.

Cladding Technologies Training (347)  

This training took place at the EuroTAC 2019 Fall Meeting and included presentations on cladding techniques and designs. Weld overlay, explosion bond cladding, tantalum loose lining techiques, and resistance weld cladding techniques were presented, as well as design considerations for attaching internals, cladding repair techniques, and quality control for cladded plates.

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) of Taiwan. After carefully analyzing tens of thousands of test data voluntarily provided by the major suppliers, ITRI team carried out lab corrosion rate study then provided a statistically analyzed corrosion rate and standard deviation for each selected alloy. A final report was published in both English and Chinese. This publication has been approved by many MTI members to be extremely useful, especially when they are doing research on these alloys, selecting these alloy for certain applications, or trying to find a suitable supplier for their new project.
Project 367 is phase II of project 269. The purpose of this new project is to continue the successful effort and collect corrosion data for more nickel alloys of interest by the industry. The team will define the scope of the study candidates, assemble subject experts from member communities, collecting existing data and testing methods from industry then select qualified contractor to carry out the study.

Corrosion Data of the Most Commonly Used Corrosion-Resistant Nickel Alloys ...  

Corrosion-resistant nickel alloys are finding more and more applications in various industries, particularly chemical and petrochemical industries. MTI can continue to play important roles in promoting the safe and more efficient global applications of nickel alloys.
The purpose of this project is to develop corrosion data for selected common nickel alloys that then may be used by MTI members. Currently five types of nickel alloys are selected by the project team based on their popularities, including UNS N06022, N06600, N06625, N08825A, and N10276.

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 their careers. A secondary goal is to create the technical material that will be used to create an online training course on the same topics. The development of the online course will be developed as a subsequent MTI project.

Design For Inspection (177)  

The current situation is that some equipment gets built and delivered that is very difficult to inspect. Since most equipment used in the CPI requires routine, scheduled inspection, ownership of equipment that is difficult or impossible to inspect and certify for continued use is expensive to own since the inspection may call for the equipment to be cut apart, inspected, re-welded, and tested before it can be returned to service.
The premise for this project is that MTI will get a handbook that enumerates or lists design "tricks" and options so that they can be used by member companies to help in writing their design standards. The goal is to have standards that incorporate these design details so that member companies can maximize the value that they get in purchased equipment.

Development of Supplementary Requirements - Flanges (271)  

A number of failures and near misses have occurred in the CPI with carbon steels that did not receive appropriate heat treatment or was properly forged. The failures are due to lack of details in ASTM standards, or conflicts between ASTM standards and ASME when specifying materials.
A project team was formed to consolidate and homogenize the ASTM standards and other standards to eliminate confusion on what standards are required to ensure the performance of materials in the CPI and refining industry.

Duplex Stainless Steels at Elevated Temperatures (364)  

Following project 307, which was a thorough literature search on the topic of Duplex SS at elevated temperatures for short term exposures, this project was formed to fill in some of the gaps in knowledge of the affect on mechanical properties of DSS after repeated exposures, as well as the order of the aging exposures. A series of exposures will be conducted and mechanical properties tested and compared to draw conclusions of the ability of these alloys to withstand short term exposure above recommended temperatures.
