A high quality Atlas of Microstructures will be developed for all product forms and welds for the corrosion resistant nickel alloys commonly used in the CPI.
This project seeks to develop a compilation of industry best practices for materials selection, design and construction of reactive (titanium and zirconium) and refractory (tantalum and niobium) metals for equipment and piping in the Chemical Process Industries.

Idea under development within the AsiaTAC PDC.

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.

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 (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.
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-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.
This project will explore solutions to corrosion under insulation (CUI) in carbon steel including selective alloy additions to carbon steel and mill applied thermal spray aluminum.

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.
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.
This project is to develop an eLearning electronic course available on the internet for FRP inspection of in-service equipment. The course and its content will be owned by MTI.

The scope of this project is to perform a study in order to include in the simulation model developed in the P305: - Discrimination of the HTHA damages with inclusions by inserting them as a specific modeled item. - Validation of the model to samples with actual HTHA damage in the welded area.

The project is a multi-phase project which finally has three objectives:1.Identification of the sensitivity of available NDT-methods for HTHA, and development of a NDT-strategy in case of an HTHA-risk in a carbon steel component.2.Elaboration of a relation between the degradation of the load bearing capacity and toughness of carbon steel and the amount and distribution of HTHA.3.Development of a more quantitative understanding of HTHA in carbon steel which allows to better estimate the damage progress with the service time and to find out the impact of parameters like temperature and pressure on the progress of HTHA.
