The Reliable Sealing Solution for Your Industry
What is Spiral Wound Gasket ?
Spiral wound gasket are metal-based gaskets designed for flanges, valves, and critical sealing needs. They feature helically wound metal strips shaped like a V or W. Combined with flexible filler material, they create a strong seal. The metal provides strength and pressure resistance. Meanwhile, the filler prevents leaks and ensures tight sealing. This design allows spiral wound gaskets to handle extreme conditions effectively.
Advantages of Spiral Wound Gasket
Spiral wound gaskets bring multiple advantages to various applications:
Extreme Temperature Resistance: Suitable for harsh environments with high temperatures.
Perfect Seal: The metal and filler combination prevents fluid leakage.
High Flexibility: Available in various types and sizes for different needs.
Superior Durability: Built from high-quality materials for long-term use.
Instalasi Mudah: Quick to install and remove, reducing downtime.
These benefits make them highly valued in critical industries.
Types of Spiral Wound Gasket
B Style
Style B gasket consists of sealing element only. It comes with some additional layers of winding strip when used in tongue and groove and male/female flanges. It is available in various shapes, including oval, obround, and diamond.
OB Style
This type of gasket consists of outer ring and sealing element. It is most suitable for RF and FF flanges. We made it accordingly standards to guarantee its quality.
BI Style
The standard BI style consists of an inner ring and a sealing element. This ring is heat and corrosion resistant. This ring is also available in various shapes such as oval, obround, diamond, etc.
OBI Style
The standard OBI style consists of outer ring, sealing element, and inner ring. The outer ring is color coded based on the material that constructs it. It is heat and corrosion resistant due to its extra inner ring fitted that provides an additional compressions stop.
Spiral Wound Gasket Components
Spiral wound gaskets consist of three key parts :
1. Metal Winding
Materials :
- Stainless Steel: The most common choice due to its corrosion resistance and extreme temperatures. Commonly used types include SS304, SS316, and SS316L.
- Description: The metal winding forms the main structure of the gasket, providing mechanical strength and pressure resistance. The winding shape is usually V or W, which clamp the filler material.
2. Filler Material
Materials :
- Graphite: Resistant to high temperatures and has good compression capabilities, suitable for applications with extreme temperatures and pressure fluctuations.
- PTFE (Polytetrafluoroethylene) : Chemically resistant and has a low coefficient of friction, ideal for applications with corrosive fluids.
- Ceramic Fiber: Withstands very high temperatures and has good thermal insulation properties.
- MICA : is a group of silicate minerals that have a layered structure and Some common types of mica are muscovite and phlogopite. Mica has good heat resistance, high electrical insulation, and is chemically stable.
- Other Non-Asbestos Materials : Other materials can also be used as filler materials, depending on the application and working conditions.
- Description: The filler material acts as the primary seal, filling small gaps on the flange surface and preventing leakage. The filler material should be selected according to the type of fluid, temperature, and working pressure.
3. Ring
Materials :
- Carbon Steel: used for the inner ring or outer ring due to its strength and economical price.
- Stainless Steel: Used for the inner ring or outer ring if better corrosion resistance is required.
- Description: The ring serves to provide additional stability to the gasket and protect the winding from damage. The outer ring also helps center the gasket when installed on the flange.
Together, these components create a durable and flexible sealing system.
Choosing the Right Materials
Selecting the correct gasket material is crucial for performance. Consider these factors:
Type of fluid sealed.
Operating temperature range.
Working pressure conditions.
Environmental exposure risks.
Proper material choice ensures reliable sealing and longer gasket life.
High-Quality Materials We Use
Our spiral wound gaskets use only top-grade materials:
Metal Winding: Stainless steel (SS304, SS316, SS316L).
Filler Material: Graphite, PTFE, ceramic, or MICA.
Rings: Carbon steel or stainless steel for added durability.
These materials ensure maximum performance in demanding applications.
