Grooved Metal Gasket With Covering Layers

At Kriloha Ltd., we understand that “Severe-Service” demands a gasket that is both rigid and adaptable. Our Grooved Metal Gaskets with Covering Layers (often referred to as Kammprofile or Camprofile gaskets) are our engineered answer for “High-Pressure-Containment” and “Cyclic-Thermal-Reliability.” As a premier global provider of industrial components, Kriloha has developed a grooved technology that balances mechanical invincibility with the sealing agility required for modern industrial plants.

The engineering of our grooved series is based on Concentric Pressure-Pointing. By machining precise V-shaped grooves into the metallic core, we concentrate the bolt load onto a smaller surface area, significantly increasing the sealing stress. At Kriloha, we verify that our covering layers—whether high-purity graphite or expanded PTFE—are bonded with precision to prevent “layer-slip” during installation. This creates a “Hybrid-Seal” barrier that offers the blowout safety of a metal gasket with the sealing ease of a soft gasket.

Manufacturing these gaskets involves strict Groove-Pitch Calibration. We ensure that the depth and spacing of the grooves are optimized for the specific flange finish and available bolt load of your system. Whether you are sealing a critical heat exchanger or a high-pressure valve bonnet, Kriloha Grooved Metal Gaskets provide the mechanical durability your facility demands. By choosing Kriloha Ltd., you are investing in a “High-Integrity” technology that secures your assets against the most punishing operational cycles.

Primary Use Cases

- Heat Exchangers: Managing the thermal expansion and contraction cycles in shell-and-tube exchangers.
- High-Pressure Valve Bonnets: Providing a robust seal for the primary pressure-containing joints in industrial valves.
- Steam Headers: Handling superheated steam in power generation facilities where standard gaskets might suffer from “creep.”
- Petrochemical Flanges: Used in refinery piping where a combination of high pressure and volatile hydrocarbons requires a fire-safe, high-integrity seal.

FAQ's

Is this the same as a Kammprofile gasket?
Yes. “Grooved Metal Gasket with Covering Layers” is the technical descriptive term for what is commonly known in the industry as a Kammprofile or Camprofile gasket.

Can these gaskets handle flange misalignment?
While the soft layers help compensate for minor surface imperfections, these gaskets are very rigid; significant flange misalignment should be corrected to ensure uniform loading across the grooves.

Why choose this over a Spiral Wound Gasket?
Grooved metal gaskets are often preferred for heat exchangers because they are easier to handle, do not require a compression stop (outer ring), and provide superior seal integrity in high-vibration environments.

Are these gaskets fire-safe?
Yes. When used with graphite or metallic covering layers, these gaskets are inherently fire-safe and can maintain a seal even after extreme heat exposure.

What information is needed for a custom order?
Kriloha requires the Outer Diameter (OD), Inner Diameter (ID), Core Thickness, and the desired Covering Layer material to provide a precision-fit solution.
