Flange insulation kit types

Ridderflex supplies different types of flange insulation kits according to DIN and ANSI sizes:

Type DType D is intended for the standard ring type joint flanges. The section of the seals can have an oval shape.
Type EThis set has flat gaskets for full face flanges (with bolt holes).
Type FThis set has flat gaskets for raised face flanges (without bolt holes). Type F is not as efficient as type E, but it has the advantage that it can be mounted without disassembling the entire flange.

Mounting

The flange insulation set has to be mounted at strategic points. We are happy to advise you. Please contact our sales department!
