Spiral/Metal-Toothed/Corrugated Metal Gaskets: High-Performance Sealing Solutions

Metal gaskets are critical components in industrial applications where high pressure, extreme temperatures, or corrosive environments demand reliable sealing. Among the most effective types are spiral wound, metal-toothed, and corrugated metal gaskets, each offering unique advantages depending on the application.

1. Spiral Wound Gaskets: Flexibility and Strength

Stainless steel spiral wound gaskets are among the most widely used sealing solutions in piping systems, pressure vessels, and flanges. They consist of alternating layers of metal (typically stainless steel) and a soft filler material (such as graphite or PTFE), providing both resilience and compression resistance.

Key Benefits:
High pressure and temperature resistance – Ideal for oil & gas, chemical, and power plants.
Excellent sealing performance – The spiral design allows for flexibility while maintaining a tight seal.
Vibration and thermal cycling resistance – Prevents leaks in dynamic systems.

2. Metal-Toothed Gaskets: Bite into Leakage

Metal-toothed gaskets (or serrated gaskets) feature a grooved surface that "bites" into flange faces, creating a strong mechanical seal. They are commonly used in high-pressure bolted connections.

Key Benefits:
Enhanced sealing under high pressure – The serrations improve grip and prevent blowouts.
Reusability – Unlike softer gaskets, metal-toothed variants can often be reused.
Minimal creep relaxation – Maintains seal integrity over long periods.

3. Corrugated Metal Gaskets: Versatile and Durable

Corrugated metal gaskets have a wavy or ridged design, allowing them to conform to flange irregularities while maintaining a strong seal. They are often used in heat exchangers, boilers, and exhaust systems.

Key Benefits:
Conforms to uneven surfaces – Compensates for minor flange imperfections.
Handles thermal expansion – Ideal for applications with frequent temperature fluctuations.
Wide material options – Available in stainless steel, copper, and other alloys.

Stainless Steel Spiral Wound Gasket: The Go-To Choice for Industrial Sealing

Spiral wound gaskets, particularly those made from stainless steel, dominate industries requiring leak-proof performance under harsh conditions. Their layered construction ensures durability, making them a preferred choice for:

Oil refineries & petrochemical plants
Power generation systems
High-pressure steam applications

Metal Gasket vs Rubber Gasket Comparison: Which One Should You Choose?

While metal gaskets excel in extreme environments, rubber gaskets are better suited for low-pressure, non-corrosive applications.

When to Choose Metal Gaskets:
Extreme heat/pressure conditions
Corrosive chemicals or steam applications
Long-term durability needed

When to Choose Rubber Gaskets:
Low-cost, low-pressure sealing
Vibration damping (e.g., automotive)
Food-grade or sanitary applications
