Creating Durable Seals in Glass-Lined Steel Equipment with Gore
Gore's Gasket Tape 1000 Series is made of expanded polytetrafluorethylene (ePTFE) and is specifically designed to address the most challenging seal applications and demanding environments.
Equipment made of glass-lined steel is used when manufacturing or processing aggressive chemicals such as aniline derivatives and sulphuric or hydrochloric acid. The Achilles heel of such systems is the gaskets

GORE® Gasket Tape
GORE® Gasket Tape is a 100% ePTFE form-in-place gasket that delivers worry-free sealing performance for large steel flanges (Series 500) and large glass-lined steel equipment (Series 1000). While this product has a number of advantages, a few years ago, GORE® made a significant design change in the adhesive size to ensure easier placement and handling of their proprietary gasket tape.

Since 1958, Gore has developed products that improve lives. At the center of these solutions is polytetrafluoroethylene (PTFE), a polymer with exceptional properties like high tensile strength, a low dielectric constant, UV resistance and many more. In 1969, the possibilities for PTFE expanded with Bob Gore’s discovery of expanded PTFE, or ePTFE.
In the years since, Gore has developed unparalleled expertise in manipulating ePTFE and other fluoropolymers. Gore's engineers can change a material’s structure, shape, thickness and surface geometry, then pair it with complementary materials to provide the performance qualities required by the application and the customer. The resulting product can be strong or permeable, rigid or flexible, thin or thick — with many additional combinations of properties that can be applied to meet the end use requirements.
Since its very founding, Gore has been passionate about solving the complex challenges of their global customers. From the first suggestion of a product need, to its delivery to market, this passion is apparent in everything Gore does.
- Curiosity: From keeping water off a person’s skin to preventing leaks from happening in chemical containers, Gore listens to their customers and analyze the challenges to determine the underlying problem.
- Competency: Gore determines how they can apply their expertise in fluoropolymer science to deliver solutions that are valued and differentiated from the competition.
- Commitment: Gore rigorously tests their products to ensure they deliver failure-free performance and suit their customers’ needs and applications, the first time and every time.

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.
More aggressive media and higher internal pressures have pushed the limits of the commonly used rubber gasketing materials, such as Nitrile Butadiene Rubber (NBR), Ethylene Propylene Diene Monomer (EPDM), or neoprene. Obtaining a reliable seal in FRP flanges using conventional gasketing materials has become more difficult.
Fiberglass pipes are generally known to have strength limits and a lower pressure resistance, making sealing fiberglass flanges difficult. Gore solved this problem with its patented expanded polytetrafluoroethylene (ePTFE) gasket, specifically designed to seal flanges at low stresses. This solution was successfully demonstrated in a multistage testing procedure conducted in cooperation with a globally leading manufacturer of anti-corrosive fiberglass pipe systems.

ePTFE Gasket Tapes for High Chemical Resistance
The connections to shell and tube heat exchangers pose immense challenges for the seals that are used because of both the chemically aggressive media and the frequent temperature load changes. Despite its excellent chemical resistance,polytetrafluoroethylene (PTFE) is not typically suitable as a sealing material in this case because the creep tendency of this material jeopardizes a reliable seal.
