Proper selection of a spiral seal is critical to its successful application.
There are many different styles of gaskets and types of materials available to offer a wide range of options to achieve the best seal.
To select a suitable spiral wound for the application, it is necessary to analyze the application information. Typically, the more information that can be gathered, the more success you will have in determining the best option.
The important information required for the selection of a spiral wound is the temperature, the operating pressure, the chemical substance inside, the type with the dimensions and the materials of the flange, the limits of the clamping force of the flange, the number of bolts and the type of bolts.
