I. Application Scenarios of Gylon 3500 Gasket Insulation Set
Gylon 3500 is a modified PTFE gasket material that combines PTFE's excellent chemical corrosion resistance with improved creep resistance. It is specifically designed for highly corrosive media and high-purity applications.

This 14-inch 300-class Gylon 3500 Gasket Insulation Set, which includes G11 insulating sleeves, insulating washers, and ZPS metal gaskets, is primarily used in the following scenarios:

1. Cathodic Protection Pipeline Systems: In long-distance oil and gas pipelines and subsea pipelines, cathodic protection is applied to prevent electrochemical corrosion. The Gylon 3500 Gasket Insulation Set effectively electrically insulates the pipelines on both sides of the flange while maintaining a reliable seal.

2. Chemical and Petrochemical Industries: Suitable for flange connections conveying corrosive fluids such as strong acids, strong alkalis, and solvents. The chemical inertness of Gylon 3500 material ensures it will not be corroded in aggressive media. The Gylon 3500 Gasket Insulation Set is widely used in chemical plant process piping, reactor connections, and heat exchangers.

3. Applications Requiring Prevention of Galvanic Corrosion: When connecting flanges made of dissimilar metals, the Gylon 3500 Gasket Insulation Set can block the electrical path, preventing severe galvanic corrosion caused by potential differences.

II. Comparison with Klinger C4430 Gasket
Klinger C4430 is also a non-asbestos compressed fiber gasket material made from synthetic fibers, glass fibers, and an NBR (nitrile butadiene rubber) binder. The main differences are as follows:

- Material Structure and Composition: Gylon 3500 is a microcellular PTFE with a denser, more uniform structure, offering excellent creep and cold flow resistance. However, the Gylon 3500 Gasket Insulation Set provides a complete insulation solution, including G11 sleeves and insulating washers, which completely isolates metal-to-metal contact between bolts and flanges, as well as between flange faces, achieving true electrical insulation. C4430 is a combination of synthetic and glass fibers with good stress relaxation, but typically serves only as a sealing gasket itself and does not constitute a complete insulation assembly. While its fiber fillers offer some electrical resistance, it is not designed for electrical insulation.

- Core Performance: Both materials outperform ordinary PTFE in sealing and creep resistance. The microcellular structure of Gylon 3500 allows it to maintain bolt preload better under temperature and pressure cycling. The key distinction is that the Gylon 3500 Gasket Insulation Set is a complete kit specifically engineered to achieve electrical insulation, a feature C4430 does not possess. C4430, reinforced with fibers, maintains good mechanical strength at high temperatures and is suitable for applications like high-pressure steam and hot oils.

- Application Areas: The Gylon 3500 Gasket Insulation Set has a very precise focus: pipelines requiring both corrosion-resistant sealing and mandatory electrical insulation, such as cathodic protection systems and the chlor-alkali industry. C4430 is more oriented towards general severe corrosion sealing applications, with a broader range of uses, such as process lines for strong acids, alkalis, and chemicals, focusing more on chemical resistance under high temperature and high pressure.
