DuPont is proud to take part at the upcoming Industrial Valve Summit in Bergamo, Italy on 24-25 May. The Industrial Valve Summit brings together stakeholders involved in valve technologies and flow control solutions to discuss technical challenges and opportunities, introduce pioneering technology, and share experiences.
At this year’s event DuPont will present a paper on the results of their research into low and high temperature elastomeric sealing systems for valves in harsh environments such as oil and gas production.
The paper provides results on their testing of a solution to one of the key challenges being faced by valve manufacturers specifying perfluoroelastomer seals: the need to meet both low temperature and high temperature requirements in a single sealing solution. Such seals often also need Rapid Gas Decompression (RGD) certifications such as Norsok M710 rev 3 / ISO 23936-2 / Total GS EP PVV 142 and excellent chemical resistance. Back up rings are also typically required to prevent extrusion of high durometer O-rings under high temperature and high pressure conditions. Meeting all these requirements at reasonable cost is not an easy task.
This DuPont paper details the results of their advanced testing of a solution to this challenge through a perfluoroelastomer seal with sufficient extrusion resistance at high temperature to allow the removal of back up rings. This is shown to significantly enhance low temperature sealing performance as well as reducing total sealing system cost by simplifying assembly, reducing part count, and…
