Overlays for Wear Protection
September 22, 2022
Gary Fisher, Principal Engineer, Innotech Alberta
Overlays are an effective option for the protection of equipment in aggressive wear environments.

This webinar will give an overview of welding processes and overlay types, common quality issues and the performance of a range of systems.
Effective Use of Duplex Stainless Steel in Storage Tanks and Pressure Vessels
December 14, 2021
Claes Tigerstrand, Head of Heavy Industry, Technical Value Creation, Outokumpu
This webinar will elaborate on the advantages of selecting duplex stainless steels for large storage tanks or pressure vessels compared to both the more commonly used austenitic stainless steels, type 304 and 316, and carbon steels. The great combination of high mechanical strength and durability can potentially provide a more economical design. This can be realized by enhancing the structural efficiency which reduces the material consumption and shortens the fabrication time when thinner plates are assembled and no protective coatings are applied. Moreover, higher durability reduces the need for costly maintenance and repair work which facilitates a more reliable and long-lasting operation. Nevertheless, there are some considerations associated with the use of duplex stainless steels such as the more limited temperature range and the importance of being aware of how important material properties are affected by the different steps of the fabrication process. Thus, both opportunities and challenges will be addressed.Ultrasonic Array Techniques for Detection, Characterization and Sizing of High Temperature Hydrogen Attack

April 16, 2021
Pradip Khaladkar, MTI
Polymer-based materials have been used since wooden vats were found to be corrosion resistant for pigment and dye manufacturing and properties of vulcanized rubber were discovered in 1832. Many materials have been invented since that time, and these materials are now commonly used for applications ranging from corrosion resistance to product purity. This presentation traces the evolution of polymer-based materials leading to the current state of the art. It reviews the challenges they face in the future and how the industry is responding to the critical issues related to accelerated testing for compatibility, nondestructive and non-intrusive testing for condition assessment and fitness for service evaluation.Albemarle's Journey to Bolted Flanged Joint ExcellenceDate Recorded:

The objective of the initiative and mechanic training was to improve the Mechanical Integrity of bolted flange joints, achieve safe and reliable plant operation, maximize asset longevity, and minimize the potential for loss of primary containment of hazardous chemicals. Much progress has been made in this regard, and this presentation takes participants through the journey to date.Sealing Non-Metallic Flange Joints – Challenges and ConsiderationsDate Recorded:
December 9, 2020
Matt Tones and Jim Drago, Garlock Sealing Technologies
A new FRP tank requires a metal gate valve with raised face flange to be joined to one of the tank's flanged nozzles. The rubber gasket originally specified won't work, due to media incompatibility...what's next? Non-metallic pipe systems are commonly specified when corrosion is of chief concern and the cost of exotic metals is high. There are basic and special considerations for the selection and application of gasket materials.
Welding Metallurgy of Duplex Stainless Steels
Date Recorded: August 26, 2020
Instructor: Ravi Vishnu, Outokumpu
The historical evolution of different generations of duplex stainless steels will be traced and it will be shown how welding metallurgy has played a central role in these developments.
One impediment to the successful use of duplex stainless steels today is an incomplete understanding of the relevant standards governing welded constructions. An attempt will be made to present a nuanced understanding of different requirements in the codes related to welding. One common source of confusion is the differences in the requirements in many national and international standards. The differences will be highlighted, and an effort will be made to explain why they may have arisen.

Stress Relief Cracking in High Temperature Alloys
Date Recorded: December 17, 2019
Instructor: Rishi Kant, Lehigh University
Many alloys used at high temperature exhibit stress relief cracking (SRC) during welding and/or post weld heat treatment (PWHT). This form of cracking typically occurs along the grain boundaries and results in a low ductility fracture. The problem is often associated with precipitation strengthening of matrix and localization of plastic deformation at grain boundaries to relax residual stresses from welding. In this work, we considered the effect of variations in PWHT temperature and cold working on the SRC susceptibility of a range of austenitic and ferritic alloys (Inconel 617, 740H, Haynes 230, 282, 347H, Grade 22 and 22V). Gleeble-based tests were developed that accurately simulate the cracking mechanism and provide very good control over temperature, stress and strain. The test results were rationalized based on detailed microstructural characterization and well-established concepts from literature. Six measures of SRC susceptibility were also identified and combined with concepts of Risk Priority Number (prioritization tool in 6-Sigma) to devise a ranking methodology for SRC susceptibility of alloys.Use of Fluoropolymers in Corrosion Control in the Chemical Process Industries
