Join GPT for a unique insight into the most common failure modes of isolation gaskets and how to avoid and overcome these issues. GPT's application engineering team is exposed to various challenges and issues faced by corrosion professionals. In this educational webinar we will review two of the most common failure scenarios.
1) Electrical bridging across the flange causing a loss in isolation
2) The challenge in using isolation gasket types in an RTJ flange due to surface finish What you will learn:
1) As conditions continually change in our industry, we are finding that maintaining isolation throughout the life of service can become more and more challenging. One reason for this is because the media and its byproducts that are traveling through the pipeline can be conductive. Electrical bridging has always been an issue with isolation, but this failure mode seems to be on the rise. If the loss of isolation is not the isolation gasket itself, but the media within the pipeline, how does one properly isolate and can an isolation product solve this failure mode? GPT has worked on innovative solutions to combat this, and ensure that isolation will be kept no matter what is going through the pipeline, so that your pipelines and flanges will be protected for the lifetime that is expected.
2) GPT isolation gaskets are designed and engineered to be used in RTJ flanges, but is there anything else to take into consideration? When using GPT isolation gaskets in RTJ flanges, these will seal on the flange face, with the seal landing on the surface between the RTJ groove and the bore of the flange. With this being the case, these gaskets do not use the typical sealing area of an RTJ flange. As a result, this can lead to the gasket not being able to seal to the best of its capabilities. We will go over what to look for with RTJ flanges, what surface finishes are recommended for best performance, and why this is the case.
