Key Features & Unmatched Benefits of Dipti Metal's Spiral Wound Gaskets
- Exceptional Resilience & High Recovery: The spiral construction provides a "spring-like" action, allowing the gasket to effectively compress and recover under fluctuating pressure and temperature conditions, maintaining a consistent seal.
- High Temperature & Pressure Resistance: Designed for severe service, SWGs can withstand extremely high operating temperatures (cryogenic to 1000°C+, depending on filler and metal) and high pressures (up to ASME Class 2500), outperforming many non-metallic gaskets.
- Superior Blow-out Resistance: The robust metallic winding, often supported by inner and/or outer rings, provides excellent structural integrity and inherent **blow-out resistance**, ensuring safety in critical applications.
- Fire Safe Certification (API 607 / API 6FB Compliant): Many of our spiral wound gaskets, particularly those with flexible graphite fillers, are designed and tested to be fire-safe, maintaining seal integrity during and after fire exposure.
- Broad Chemical Compatibility (Material Dependent): The choice of winding metal and filler material allows for precise tailoring to resist a vast array of corrosive chemicals, acids, alkalis, and hydrocarbons.
- Conformability to Imperfections: The soft filler material ensures excellent conformability to minor flange surface irregularities, enabling a tight seal even on imperfect flange faces with lower bolt loads than solid metal gaskets.
- Versatile Design Options: Available in multiple configurations (Basic, with inner ring, with outer ring, with both) to suit various flange types (Raised Face, Flat Face, Male & Female, Tongue & Groove) and application specific requirements.
- Cost-Effective for Large Diameters: Can be economically manufactured in very large diameters, offering a cost-efficient solution for large vessels and heat exchangers.
- Reduced Flange Damage: While offering robust sealing, the design helps prevent damage to expensive flange surfaces by allowing controlled compression.
Spiral Wound Gaskets: Comprehensive Types, Winding Metals & Filler Materials
DIPTI METAL INDUSTRIES offers a highly specialized and comprehensive range of Spiral Wound Gaskets (SWG), meticulously manufactured and available in various types, winding metals, and filler materials to perfectly match your specific operating conditions, demanding fluid compatibility, and exact flange sealing requirements. We provide custom-manufactured SWGs alongside all international standard dimensions and specifications, ensuring optimal fit, maximum performance, and full compliance for every critical application worldwide. Our SWGs are typically manufactured to ASME B16.20 for pipe flanges, and fire-safe designs comply with **API 607 / API 6FB**.
1. Types of Spiral Wound Gaskets (ASME B16.20 Styles):
Consists only of the metallic winding and soft filler material. No inner or outer rings. The outer diameter of the winding serves as the centering guide.
- Applications: Designed for Tongue and Groove, Male and Female, or Flat Face flanges. Limited to lower pressure classes or specific custom applications where inner/outer rings are not feasible or necessary.
Includes a solid inner metal ring in addition to the metallic winding and filler. The inner ring acts as a compression stop, prevents radial buckling (inward collapse) of the gasket, and minimizes erosion of the filler material by turbulent flow.
- Applications: Recommended for pipe flanges where conditions of high pressure, high temperature, or vacuum exist, or where media is toxic/corrosive. Often used on Male and Female, Tongue and Groove flanges.
Features a solid outer metal ring (centering ring) in addition to the metallic winding and filler. The outer ring accurately centers the gasket on the flange face, acts as a compression stop, and prevents outward bulging. It also protects the winding from environmental factors.
- Applications: The most common style, designed for use with Raised Face and Flat Face flanges in pressure classes 150 to 2500. Suitable for a wide range of general and demanding industrial services.
Incorporates both an inner and an outer solid metal ring, in addition to the metallic winding and filler. This provides the ultimate level of sealing integrity, compression control, radial buckling prevention, and protection.
- Applications: Recommended for Raised Face and Flat Face flanges in critical services, especially those with high pressure, high temperature, vacuum, and toxic or aggressive media. Offers superior performance in fluctuating conditions and is often preferred for fire-safe applications.
2. Winding Materials & Grades for Spiral Wound Gaskets:

| Carbon Steel | ASTM A283 Gr. C / A516 Gr. 70 | Economical for non-corrosive, lower temperature & pressure duties. |
3. Filler Materials & Grades for Spiral Wound Gaskets:
The filler material dictates the gasket's conformability, sealability, and much of its temperature and chemical resistance.
| Filler Material | Key Properties & Applications | Temperature Range (Guide) |
|---|---|---|
| Flexible Graphite | Superior high-temp. resistance, excellent chemical inertness (pH 0-14), outstanding resilience, fire-safe. | -200°C to +500°C (oxidizing), +3000°C (inert) |
| PTFE (Virgin or Expanded) | Exceptional chemical resistance (near universal), high purity, non-contaminating, low friction. | -240°C to +260°C |
| Mica | Extremely high-temperature resistance, good dielectric properties. Less compressible than graphite. | Up to +1000°C |
| Ceramic Fiber | Very high-temperature resistance, good thermal insulation. | Up to +1200°C+ |
| Non-Asbestos Fiber (CNAF) | Blend of aramid/inorganic fibers with rubber binders. General purpose, moderate temp/pressure. | -50°C to +250°C (binder dependent) |

Spiral Wound Gaskets — Frequently Asked Questions
We offer Basic (Style R), Inner Ring (Style RIR), Outer Ring (Style CG), and Inner & Outer Ring (Style CGI) spiral wound gaskets to suit various flange types and application demands, all manufactured to ASME B16.20 standards.
Winding materials include Stainless Steel (304, 316L, 321, 347), Duplex/Super Duplex, Monel®, Inconel®, Hastelloy®, Titanium, and Carbon Steel. Filler materials include Flexible Graphite, PTFE (Virgin, Expanded), Mica, and Ceramic Fiber. Material choice depends on specific temperature, pressure, and chemical compatibility requirements.
They offer excellent resilience and high recovery under fluctuating pressure/temperature, high pressure/temperature resistance (fire-safe options available), and broad chemical compatibility, providing a robust, leak-free seal. Their unique design also gives them superior blow-out resistance compared to many other gasket types.
Our SWGs are manufactured to ASME B16.20 for metallic gaskets for pipe flanges. Fire-safe designs comply with API 607/6FB. Materials can meet NACE MR0175/ISO 15156 for sour service applications. We also comply with relevant ISO and EN standards.
Yes, many Spiral Wound Gaskets, particularly those with flexible graphite fillers and appropriate metallic windings, are designed and tested to be fire-safe according to standards like API 607/6FB. This ensures they maintain seal integrity during and after exposure to fire, which is critical for safety in hazardous environments.
The filler material significantly impacts SWG performance. Flexible Graphite fillers offer high temperature and chemical resistance, and excellent recovery. PTFE fillers provide superior chemical inertness and purity for corrosive or sensitive applications. Mica fillers are primarily for extreme high-temperature use, while Ceramic Fiber provides very high thermal insulation at extreme temperatures.
