Product Data Sheet

Application

Steel and enamel flanges, Heat exchanger, Plant / Containers, For high surface stress, For highly aggressive media, For damaged sealing surfaces. Food and Farma

Advtantages

Compressable and good resistance behaviour of the material leads to increased operating safety, even in changing operating conditions.

Chemical Compatiblity

Patricularly suitable for use with hydrofluoric acid, but not pure hydrogen fluoride. Best for use with string alkalis, solvents, fuels, water, steam and chlorine. Other applications include solvents, fuels, water, oil, chlorine and caustics. A chemical resistance list is available upon request.

Delivery Options

Flange gaskets and sheets are available in thickness of 1/32",1/16", 1/8". Other thicknesses available on request. Standard gaskets can be supplied in accordance with ASME B16.21. Non-standard or special gaskets can be manufactured according to customer drawings, or by given sizes or Edrawing.
