Pipex.ai is a leading global B2B marketplace that connects industrial buyers with verified suppliers for critical components like flanges, fasteners, gaskets, and more. In the world of industrial maintenance, repair, and operations (MRO), reliable sealing is essential. Among the wide range of gasket options available today, Spiral Wound Gaskets stand out as a trusted choice for high-pressure and high-temperature applications. With the support of innovative B2B services, businesses can now source these vital components faster and more efficiently than ever.

What is a Spiral Wound Gasket?

A Spiral Wound Gasket is a semi-metallic sealing device made by spirally winding alternating layers of a metal strip and a soft filler material, typically graphite, PTFE, or mica. The metal (often stainless steel or an alloy like Inconel) provides strength and resilience, while the soft filler conforms to flange imperfections and ensures a tight seal.

The gasket is reinforced with inner and outer steel rings. The inner ring protects against media erosion and helps center the gasket, while the outer ring acts as a compression limiter and aids in proper installation. This unique construction offers excellent compressibility and recovery, making spiral wound gaskets suitable for extreme operating conditions.

Applications and Advantages

Spiral wound gaskets are used in a wide range of industrial applications that demand reliable sealing performance. These include:

Heat exchangers

Pressure vessels

Flanged pipe joints

Valves and pumps

Boilers and steam systems

Key advantages of Spiral Wound Gaskets include:

Temperature resistance: Can withstand temperatures up to 1000°C, depending on materials.

Pressure durability: Handles pressures from vacuum up to 250+ bar.

Recovery performance: Absorbs thermal cycling and vibration effectively.

Corrosion resistance: Available in alloys such as Inconel, Monel, and Hastelloy.

Versatility: Easily customized for various flange sizes and specifications.

Through B2B platform, procurement teams can filter gaskets based on material, temperature rating, standard compliance (like ASME or DIN), and other technical specs, simplifying decision-making.

Choosing the Right Spiral Wound Gasket

To select the ideal gasket for your application, consider:

Operating temperature and pressure

Flange surface finish and design

Media properties (chemical, pH, corrosiveness)

Applicable standards and certifications

Graphite-filled gaskets are popular for thermal endurance, while PTFE fillers are preferred for chemical resistance. For aggressive or offshore environments, Inconel or titanium windings may be required. B2B services often provide technical assistance, catalog downloads, and live support to help engineers and buyers make the right selection.

Standards and Compliance

Spiral wound gaskets are manufactured in compliance with global industrial standards, such as:

ASME B16.20 – for spiral wound gasket construction

ASME B16.5 / B16.47 – for flange compatibility

DIN EN 1514-2 / EN 12560-2 – for European applications

API 607 – for fire-safe gaskets in critical systems

Buyers on a B2B marketplace benefit from fast access to compliant products, complete with datasheets, certifications, and delivery timelines.

Conclusion

Spiral Wound Gaskets are a critical component in ensuring leak-proof, high-performance operations across a range of demanding industries. Their unique construction, ability to withstand extreme pressure and temperature, and compatibility with various media make them a trusted choice for engineers worldwide. With platforms like Pipex.ai, a leading B2B marketplace, sourcing these gaskets becomes faster, easier, and more reliable. Leveraging modern B2B services, businesses can streamline procurement, ensure compliance, and enhance operational efficiency—all while connecting with verified global suppliers in one digital hub.
