Corrugated Gaskets
Description
The 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 graphite, ceramic or PTFE 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
Available Styles:
One standard thickness of all applications : 3/32" (2.38mm), other thickness by 1/16" (1.6mm) and 1/8" (3.2mm) on required;
Corrugated core material: 0.6mm, 0.8mm, CS, 304, 316L;
Standard ANSI Class 150# & 300# ring gaskets: 1/2" ~ 60"
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
