Kammprofile gaskets

Kammprofile gaskets, which are also commonly known as serrated metal gaskets or grooved gaskets, are used for high-pressure and high-temperature sealing applications. They typically consist of a one-piece metallic core with concentric serrations or grooves on both sealing faces, often covered with a soft sealing material such as graphite or PTFE (polytetrafluoroethylene).  

These gaskets are specifically engineered to provide reliable sealing performance under pressure conditions, whereas conventional gaskets are liable to distortion or displacement failure. 

Kammprofile gaskets are manufactured in different materials and noncircular shapes with accuracy. They can also be custom-engineered to fit various applications.

Product Details

Style RK1 

RK1 is manufactured without a guide ring for tongue and groove, or recessed flange applications such as male and female. It is typically used in heat exchanger applications and applied as an upgrade to double jacketed gaskets. It is highly suggested to have the nubbin (if present) machined out as a good practice.  Where pass partitions are required, they are also kammprofiled and laminated. They are the same thickness as the ring, and securely held in place with welds. 

Style RK2 

RK2 is constructed with an integral guide ring for aligning purposes. It is suggested to be used in raised face flanges. The gasket is typically designed and sized per EN12560-6 spec for ASME B16.5 flanges, but can be manufactured to fit other standards. 


Style RK3 

RK3 utilizes a loose fit guide ring. This popular design is preferred for nominal pipe size and pressure class raised face flanges and is used in equipment with excessive radial shear characteristics, thermal cycling, and expansions.  The gasket is typically designed and sized per EN12560-6 spec for ASME B16.5 flanges, but can be manufactured to fit other standards.

Kammprofile gaskets Industry knowledge

In industrial production, kammprofile gaskets are a high-performance sealing element, which is widely used in various harsh working conditions due to its unique serrated design. However, to give full play to the sealing performance of kammprofile gaskets and extend their service life, correct use and maintenance are essential. Ningbo Rilson Sealing Material Co., Ltd., not only provides high-quality kammprofile gasket products, but also understands its use and provides customers with comprehensive professional guidance.
Precautions for the use of kammprofile gaskets:
1. ChoRilsonose the right material and specifications
First, users should choose the right kammprofile gasket material according to the specific use environment and medium characteristics. Ningbo Rilson Sealing Material Co., Ltd. provides kammprofile gaskets of various Material, such as stainless steel, alloy steel, flexible graphite composite, etc., to meet the needs of different working conditions. At the same time, users also need to pay attention to the specifications and dimensions of the gasket to ensure that it is fully matched with the flange sealing surface to avoid leakage or damage.
2. Correct installation and tightening
When installing kammprofile gaskets, it is necessary to ensure that the surface of the joint is clean, flat, free of scratches and rust. The gasket should be placed correctly on the flange sealing surface without any offset or distortion. When tightening the bolts, the principles of symmetry, cross, and gradual force should be followed to ensure that the gasket is evenly stressed and to avoid leakage caused by local overtightening or over-loosening. Ningbo Rilson's technical team can provide customers with professional installation guidance to ensure that every step of the operation is in compliance with the specifications.
3. Regular inspection and maintenance
During use, the kammprofile gasket will be affected by various factors such as medium pressure, temperature, and chemical corrosion, and its performance will gradually decline. Therefore, users should regularly check the wear, deformation, and sealing performance of the gasket to see if they meet the standards. Once the gasket is found to be aging, damaged, or the sealing performance has declined, it should be replaced in time. Ningbo Rilson not only provides high-quality kammprofile gasket products, but also pays attention to after-sales service, and can provide customers with regular maintenance inspections and necessary replacement services.
