Flat gaskets play a crucial role in many industrial applications, as they are reliable components that provide a seal between two surfaces. They prevent the leakage of liquids or gases and thus contribute to the safe and efficient functioning of systems. Flat gaskets are particularly indispensable in industries such as chemicals, petrochemicals, food processing and mechanical engineering. In this guide, you will find a comprehensive overview of the most important selection criteria for flat gaskets and find out what you should look out for when choosing a manufacturer.
Flat gaskets are static gaskets that are used between two surfaces to create a tight connection. They are often made from materials such as elastomers, rubber, PTFE, graphite and metal in order to meet various requirements. Different types of material are used depending on the area of application and the requirements placed on the gasket. Flat gaskets are used in a wide range of applications, from water and gas pipes to high-pressure systems in industry. Their selection depends on factors such as pressure,
temperature and chemical resistance.
When purchasing flat gaskets, there are several aspects to consider to ensure that the gasket is optimally suited to the intended application. The five most important criteria are explained below:
The choice of material is crucial, as flat gaskets have to withstand various influences such as chemicals, temperature and pressure. PTFE gaskets, for example, are ideal for applications that require chemical resistance, while graphite gaskets can withstand high temperatures. Choose materials that meet the requirements of your specific application to ensure the longevity and efficiency of your equipment.
Depending on the operating conditions, flat gaskets should be able to withstand the corresponding temperatures and pressures. For applications with high temperatures, such as in the petrochemical industry or power generation, graphite or metal gaskets are advantageous. Gaskets for lower temperatures and pressures, on the other hand, can be made of rubber or elastomers. The pressure class and temperature limit of the gasket are decisive factors for its functionality and safety.
The correct fit of the gasket is crucial for effective sealing. Flat gaskets must be precisely matched to the flanges or surfaces they are intended to seal. Manufacturers often offer a variety of standard sizes, but customized solutions are also possible to ensure a precise fit for specific applications. Check the exact dimensions and tolerances of the gasket in advance to ensure optimum performance.
The choice of gasket should also be based on economic considerations. Gaskets that are made of high-quality materials and meet the exact requirements usually have a longer service life and help to minimize maintenance costs. A cost-effective choice is therefore a balance between the purchase price and the service life of the gasket. Careful consideration of the cost-benefit ratio can significantly reduce the total cost of ownership.
Depending on the area of application, flat gaskets must comply with certain certifications and industry standards. For use in the food and pharmaceutical industries, for example, certifications such as FDA conformity or KTW approval are required to ensure the safety and quality of the products. In the chemical industry, on the other hand, standards such as EN 13555 (for seal characterization) or API 6A (for high-pressure applications) can be important. Make sure that the manufacturer offers the necessary certifications and quality certificates that are required in your industry.
