Gerry McWeeney,
Corporate Sales Manager – Superheat FGH Experts are suggesting that roughly 90% of material
anomalies and premature weld failures in advanced CSEF
(Creep Strength Enhanced Ferritic) steels can be
attributed to improper Pre and Post Weld Heat Treatment. While the benefits of CSEF
steels are well documented and growing in popularity, welding processes and
skill sets become more critical than on steels with lower chrome
content. Sensitivity to PWHT becomes more significant than ever before. Superheat FGH will share
results obtained in recent collaborative experimentation with EPRI, and present opportunities to utilize emerging
technological advancements and progressive process control solutions to
improve field construction results and long term sustainability. As an industry leader and innovator in Advanced
Industrial Heat Treatment Services, Superheat FGH
will attempt to she light on some of the pitfalls of traditional field
service practices and shortcomings of existing weld procedures, code
guidelines and specifications that, in many cases, have been established with
more forgiving materials in mind. |
