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.

Enrichment of the HTHA Damages Simulation Model To Take Into Account Inclusions ...  

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.

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.

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. The project objective is to use this effort to validate the qualification for materials used in fabrication of BVP equipment. This project will be authorized in two phases: Phase 1: Qualify an additive material manufacturing procedure using GMA-DED method and ER-2594 filler metal in accordance with the requirements of Section 6 in ASME Code Case (Record Number 22-1598) and ASME Section IX, Part QW, Article VI. Phase 2: Fabricate a test pressure vessel with the Phase 1 results and test it according to MTI provided design using GMA-DED in compliance with ASME Code Case (Record Number 22-1598) sections 1-14 requirements, and supplemental MTI requested test methods.

New Test Method for Titanium Hydriding (310)  

This project will search for a firm that is able to non-destructively detect titanium hydriding in plant equipment. Past MTI titanium hydride projects looked at one specific method with the aim to adapt the method to identify titanium hydriding. This project has a much broader perspective aiming to test all techniques that have the potential to detect titanium hydriding. Industry information suggests that a method already exists. A few companies indicate they can non-destructively detect titanium hydriding. With the goal of discovering the best method to detect titanium hydriding, the project team intends to find out if these firms can prove their techniques.

Performance of NDT, Simulations and Destructive Testing on Carbon Steel ...  

Following the validation of the Simulation model developed in P305, this project intends to use it to determine the best parameters and probes for the Ultrasonic testing of carbon steel damaged by High Temperature hydrogen attack (HTHA) in order to identify early stage HTHA.
The main objectives of this projects can be summed up as follows:
• Definition of optimized procedures and calibration blocks for reliable on-site HTHA detection and characterization
• Redaction of Guideline for Optimized NDT

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 that will be useful for predicting performance and lifetime.

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 specific interest is the work done in Europe by a working group led by TUV, BASF and Bayer.
