Webinar 4: Refractory Ceramic Selection for High Temperature Applications (2019)
Instructor: Jay Schickling, Chemours Inc.
Description: The purpose of this webinar will be to provide a general overview of the refractory ceramic materials that are available for thermal protection applications. General guidance will be provided on when to choose a brick or monolithic lining, and how to select a specific ceramic composition to resist the intended service conditions. This webinar Is this best suited for entry level engineers, technicians and experienced materials engineers with basic knowledge about ceramic materials
Webinar 5: Reliability of Flexible Hoses
Instructor: Steven P. Springer, Wehl Consulting Services LLC.
Description: Flexible hoses are used for many purposes in plant environments. They are very useful and provide good service when maintained and used properly. Significant issues can occur when flexible hoses are defective, damaged or misused. The purpose of this webinar is to examine the reliability of flexible hoses generally used for chemical plant services in the context of a hose management program that emphasizes mechanical integrity of these essential pieces of equipment. This webinar is this best suited for all engineers, operators and technicians who work with, and rely on, flexible hoses in chemical service.
Webinar 6: Selection & Use of Duplex Stainless Steels
Instructor: Dr. Jim Fritz
Description: Over the last twenty years, the number of available duplex stainless steels and their use across all industry sectors has grown substantially. This webinar will provide an overview of available wrought duplex stainless steels and discuss their selection and use in the process industries. The physical, mechanical and corrosion properties are reviewed and advantages and disadvantages of the duplex grades compared to austenitic stainless steels are discussed.
Webinar 7: Introduction to Explosion Cladding for Chemical Processing & Refining Applications
Instructor: Steve Sparkowich, NobelClad
Explosion cladding is a solid state welding process that uses precision explosions to bond two dissimilar metals while retaining the mechanical and corrosion properties of both. The process is most commonly used to clad steel with a thin layer of corrosion-resistant alloy metal, such as stainless steel, brass, nickel alloys, titanium, zirconium and tantalum. This presentation provides an overview of the explosion cladding process with a focus on applications in the chemical process industry, including columns, towers, reactors, heat exchangers, piping and tanks.
Webinar 8: Use of Fluoropolymers in Corrosion Control in the Chemical Process Industries
Instructor: Pradip Khaladkar, MTI
This webinar includes an overview of the use of fluoropolymers for corrosion mitigation with strong focus on barrier applications in vessels, piping, valves, hoses and expansion joints. Various types of fluoropolymers will be explained with product forms and fabrication techniques. This will be followed by a discussion of quality assurance, in-service inspection, failure analysis and fitness for service.
Webinar 9: Stress Relief Cracking in High Temperature Alloys
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.
