Corrugated Metal Gaskets

Corrugated metal gaskets are designed for high-temperature and high-pressure sealing applications where reliability, durability, and long service life are critical. Manufactured from corrugated metal cores combined with soft facing materials, these gaskets provide excellent compressibility and recovery while maintaining the strength needed for demanding industrial environments.

M&P Sealing manufactures custom corrugated metal gaskets for applications across refining, petrochemical processing, chemical manufacturing, power generation, pulp and paper, water treatment, and general industrial markets. Available in a variety of materials and configurations, corrugated metal gaskets provide an effective sealing solution for flanges, heat exchangers, pressure vessels, and process piping systems.

Corrugated Metal Gasket for High-Temperature Industrial Sealing

What Are Corrugated Metal Gaskets?

Corrugated metal gaskets consist of a thin metal core formed with concentric corrugations that create sealing ridges across the gasket surface. These corrugations improve gasket resilience and sealing performance while allowing the gasket to conform to flange imperfections.

To enhance sealability, the metal core is commonly faced with soft sealing materials such as graphite, PTFE, mica, or other specialized facing materials. The combination of metal strength and soft sealing layers allows corrugated metal gaskets to perform in applications involving elevated temperatures, pressure cycling, thermal expansion, and aggressive process media. M&P Sealing also manufactures a wide range of soft gaskets and custom non-metallic sealing products for applications where metal reinforcement is not required.

 

Benefits of Corrugated Metal Gaskets

Excellent Blowout Resistance

The metal core provides structural stability and helps maintain sealing integrity under fluctuating pressure conditions.

High Temperature Performance

Corrugated metal gaskets are commonly used in applications where traditional soft gaskets cannot withstand operating temperatures.

Improved Recovery

The corrugated design allows the gasket to recover after compression, helping maintain sealing stress during thermal cycling.

Chemical Compatibility

By selecting the appropriate facing material, corrugated metal gaskets can be used in a wide range of chemical processing environments.

Long Service Life

The combination of metal reinforcement and premium facing materials provides durability and reliability in demanding industrial service.

Corrugated Metal Gaskets vs. Spiral Wound Gaskets

While both gasket styles are used in demanding industrial applications, corrugated metal gaskets provide a simpler construction that offers excellent sealing performance while reducing overall gasket complexity.

Corrugated metal gaskets are often preferred for heat exchanger applications, lower bolt load situations, and installations requiring excellent recovery characteristics. Spiral wound gaskets remain a popular solution for high-pressure flange connections where maximum sealing performance is required.

Corrugated Metal Gaskets vs. Kammprofile Gaskets

Kammprofile gaskets utilize a machined grooved metal core with soft facing layers, while corrugated metal gaskets use formed corrugations to create sealing stress.

Both designs provide excellent performance in elevated temperature and pressure service. Corrugated metal gaskets are often selected when flexibility, lower seating stress, and economical performance are desired. Kammprofile gaskets may be preferred in applications requiring extremely low emissions and high sealing stress concentration.

Corrugated Metal Gasket (CMG)

Who better to trust with your Corrugated Metal Gasket needs than the original developer of the Corrugated Metal Gasket known as the Graphonic Gasket developed in 1987 (See the history of Graphonic Gaskets). M&P Sealing has set the standard of metal gaskets for more than 3 decades This American made product and company’s product line is the standard in respect to corrugated metal gasket technology; an excellent choice for the 150 and 300 class. The substrate geometry promotes recovery and resilience through thermal cycles and extended service life. CMGs can be direct replacements for spiral wound gaskets and can eliminate inward buckling issues while creating a seal at moderate flange stresses.

As a world-class leader in sealing solutions, we not only stock the products needed most often in the petrochemical, aerospace, electrical and food-processing industries, but we also maintain close ties with leading manufacturers to ensure the fastest possible availability of products.  M&P can provide sealing products for a wide range of applications.  WE KNOW GASKETS!
