Corrugared Gasket with PTFE Coating

Corrugared Gasket with PTFE Coating

Description

CORRUGARED GASKET WITH PTFE COATING

Corrugated metal gaskets have been proven to be both reliable and cost effective for the application on flanges and heads where boat loading is sufficient.

Corrugated metal is covered with PTFE, ceramic or graphite layer. An additional finishing layer is applied depending on the requirements of the medium to be sealed. The gaskets with soft layer on both sides are used in low pressure applications in large diameter flue gas ducts at high temperatures

 

ADVANTAGES

* Outstanding mechanical strength and thermal conductivity.

* Capable of withstanding high temperatures.

* There are almost no limitation regarding size

* Solid construction provides stability even for large diameters and ensures trouble-free handing and installation

 

APPLICATIONS

HEROOS corrugated metal gasket in the flange and the exchanger of large-size device is widely used,Paricularly in the smoke,gas,low pressure,high temperature and distorting the flange uneven conditions, the application better. At the same time, large size can be solved and easily installed occasions and replacement problems.
