Operating Philosophy

Members define activities

Staff helps make it happen

Operating mode is “town meeting”

Technical issues—TAC’s, PDC’s, & PT’s

Avoid “staff driven”

Require “champions”

Some of the Current Programs at MTI

Terahertz Imaging to Identify Defects in FRP and Detect CUI

Guidelines for Assessing Fire and Explosion Damage – 2nd Edition of Publication No. 30

Operation, Maintenance and Repair of Glass Lined Equipment


Some of the Current Programs at MTIPage 2

Understanding Metal Dusting and the Development of MD Resistant Alloys

Detection of Hydrogen in Titanium Improvements in Metal Casting Quality


Terahertz Imaging to Detect Damage in FRP Structures and Detect CUI

Program just finishing at RPI to leverage the THz imaging technology used in security programs to CPI use.

Detection of laminar defects in FRP in a manner similar to that used by NASA on the Space Shuttle

Detection of corrosion under insulation


Detection of 0.010 Inch Thick Laminar Defect in Polyester Resin FRP


Detection of Corrosion Under Insulation


Guidelines for Assessing Fire and Explosion Damage

First published 1990 2nd Printing 1992 Incorporated into API 579 Expanded 2nd Edition now in preparation


Arson and Sabotage

Must never be mentioned lightly Turns an incident site into a crime

scene Most companies hate to talk about it for

fear of copycats More common than one might think


Arson and Sabotage


Storm Damage

Notorious 2005 Hurricane season made it clear that storm damage assessment was as important as fire or explosion damage assessment

Storm damage assessment similar to fire damage assessment Balance early return to service with safe

reliable operation


Storm Damage


Wind Damage


Operation, Maintenance and Repair of Glass Lined Equipment

New book that has just been published Written by industry experts Details inspection and assessment of

GLS Liberally illustrated with repair types and

repair instructions


Installation of One Piece Agitator


Describes the Various Failure ModesExample of Thermal Shock


Illustrated Repair Techniques3 Piece Plug

Understanding Metal Dusting

Expert review of the various theories that are used to explain metal Dusting

JV with the National Laboratories for modeling Metal Dusting

Testing of various alloys for resistance to Metal Dusting

Development of a new alloy

Continuing Research into Metal Dusting

Understand the effects of additives to the gas streams to slow or eliminate metal dusting

Understand the effects of surface coatings that either protect the metal surface or poison the metal dusting reaction.


Detection of Hydrogen in Titanium

Hydrided titanium can be “glass” brittle It looks the same as non-hydrided

titanium MTI members would like a simple NDT

technique to be able to detect hydriding



Contracted to develop a simple tool to detect hydrogen

Electrical resistance change based Technique has led to another,

alternative technique that may be more sensitive


Casting Quality Prediction

Problems: Presence of intergranular solidification

shrink that X-rays can not find. This produces leaks when in service. Reduces yield of casting process

Need: Quantitative process to predict formation of

shrink and how to correct.

Nymin = 0.69

Nymin = 0.58

Niyama values are in units of (°C-s)1/2/mm



Objectives of Program Create data necessary for all important CPI

alloys Develop a procedure that can be used to

validate the capability of a foundry to use the Niyama simulation


MTI Sponsored Research

Projects that improve industrial competitiveness

Covers a wide variety of subjects that are important to members

Done by pooling funding to develop and understand materials and corrosion issues that are of common interest

Membership is open to all companies.
