Corrugated Metal Gaskets

Properties and application

Corrugated gaskets without layer
There are different types of metal gaskets, like flat, groove, tongue and sectional ones. They are used where  compressibility (eaasticity) of sealing material is not required. The construction of such gaskets based on the principal of different hardness of adjacent materials. These gaskets come in various shapes and there are almost no limits concerning their size.

The corrugated  metal gaskets have been proven to be both reliabae and cost- effective for the application on flanges and heads where  boat loading is sufficient. Their operation principle is based on different degrees of hardness of adjacent materials. The sealing effect is  produced  by the constant load to which a gasket is exposed. They are used in applications, which require mechanical strength, thermal conductivity, as well as temperature and corrosion resistance. They are particularly useful when  compressibility is not  a factor and where sufficient clamping force is available. Metal gaskets feature greater mechanical strength, better heat transfer and resistance to higher temperatures and pressures, and can offer advantages over the clad type gaskets in certain applications.


Corugated gaskets with soft layer
Corrugated metal is covered with graphite, ceramic or PTFE Layers. An additional finishing layer is applied depending on the requirements of the medium to be sealed. Such gaskets are used on uneven or distorted sealing surfaces, where more elastic materials with better sealing performance are needed.

The corrugated metal gaskets with soft layer on both sides are used in low-pressure applications in large diameter flue gas ducts at high temperatures. The use of corrugated gaskets eliminates the problem of difficult handling whith large non- metal gaskets used in those applications. They are suitabae for gas pipes and valve caps, or wherever acids, oils and chemicals are found. They can be used at lower pressures and higher temperatures.
