The European Standard EN 13555, updated in the summer of 2014, defines the sealing gasket design factors and test methods for round flange connections. This allows the comparison of the properties of gaskets. Among other things, the standard establishes a new definition of the maximum surface pressure. What changes does this bring for the operators of plants and what criteria should be considered in the selection of gaskets using the characteristic as per EN 13555?

For more than 40 years, the Sealant Technologies Group of W. L. Gore & Associates has fostered a solid knowledge of factors that influence the sealing of piping systems, vessels, pumps and valves. Our singular focus has resulted in the development of innovative and top-performing gaskets and packings. We’ve also established a comprehensive technical services program, specially designed to help customers determine the best solutions for their toughest sealing applications.

GORE® Universal Pipe Gasket (Style 800) seals a broad range of flange materials with this low stress-to-seal, exceptionally dimensionally stable and chemically resistant 100% ePTFE gasket.

GORE Gasketing products are comprised of expanded polytetrafluoroethylene (ePTFE), an inert fluoropolymer material. Some of these products may be supplied adhesive backed or screen printed. 

Dimensions applicable to ASME B16.5 Pipe Flanges and ASME B16.47 Series A, Large Diameter Steel Flanges.

Dimensions applicable to flanges according to EN1092-1 among others.

Fiber Reinforced Plastic (FRP) pipes and flanges are increasingly used in the oil and gas industry where metal is simply too heavy and expensive. In addition to cost pressure, the need for lightweight chemically resistant materials are also driving the use of fiberglass pipes and flanges. Innovations in FRP flange design coupled with improvements in manufacturing technology have allowed FRP piping to be used in even more demanding applications. However, these demanding applications have added challenges for sealing the bolted flange connections.
