Flange gaskets are flat gaskets that have a very specific application - sealing flanges. Their use is thus particularly widespread in pipeline or apparatus construction. Flange gaskets are the sealing element between two flanges or between the mounting surface and the flange. Depending on what is conveyed through the pipeline, these gaskets must be highly resistant to thermal or chemical stress. For this reason, at Rehm Dichtungen Ehlers GmbH you have a choice of various materials with different specifications.
Properties of flange gaskets
Flange gaskets are static gaskets that ensure absolute tightness at the joints of pipelines. Flange gaskets are particularly indispensable where liquids, gases or pasty media run through pipes or lines. Leakages must be prevented, especially in the case of media that are harmful to health or critical to the environment. Just like flat gaskets, flange gaskets can be used flexibly and are low-wear.
Application areas of the seals
This type of flat gasket is used in particular in pipeline construction in a wide variety of industries - be it in the oil industry, gas or waterworks or also in the context of food processing. Pipes or lines are firmly connected to each other via flanges at the end of a pipe. The flange gaskets sit exactly between these flanges, or between the flange and the mounting surface, and seal the joint.
Flange gaskets made to measure
With the help of our various manufacturing processes, we at Rehm Dichtungen can produce customised flange gaskets for you. Thanks to the different manufacturing processes, we can supply flange gaskets in a wide range of shapes and sizes. Before manufacturing your individual gasket, it is important to determine the suitable gasket material with regard to resistance to the medium to be sealed and the planned application, because both the contour and the resistance of the gasket are important factors for the tightness of the flange gasket.
Depending on the area of application, the seals must be able to withstand various media as well as temperature and pressure ranges to ensure long-term and optimal sealing.
If the seals are used in environments with high operating temperatures or in the food industry, then silicones, for example, are a good choice. For high thermal and chemical loads, rubbers such as EPDM, NR or NBR are suitable sealing materials. If good resistance to moisture and high deformability are important, sponge rubber is recommended. Depending on the material compound, sponge rubber is also oil-resistant, among other things.
The list of sealing materials that can be used for flange gaskets is long. Find out here about the gasket materials available from us, Rehm Dichtungen Ehlers GmbH, or let us advise you. Together we will find the most suitable material for your purposes.
