Kammprofile gasket offers a safe and effective seal under the most severe operating conditions for use in both standard pipe and equipment flanges.
These gaskets are suitable for use in Class 150 to 2500 flanges (ASME). They are frequently selected as a favorable replacement for double jacketed gaskets commonly used on heat exchangers and features excellent tightness providing high seal integrity and reduced emissions.
The Kammprofile gasket consists of a solid grooved metal core with soft conformable facing materials bonded on both sealing surface faces. The precise concentric machined grooves enhance sealing performance by means of inducing high stress concentrations across the peaks of the grooves during the seating of the gasket. Due to the precise machining of the grooves consistent and repeatable gasket stresses are achieved.
It is robust, blow out resistant, and does not require a compression stop to prevent over-compression.
The soft conformable facings require initial low stress for gasket seating, and the facing material is trapped within the grooves minimizing flow or extrusion.
Graphite is offered as the standard sealing face material and the metal core is grade 316L stainless steel. Other soft conformable facings offered are Thermiculite®, PTFE, Sigma®, compressed fiber, and soft metals.
Selection of facing and metal core material is dependent on application and design conditions, such as chemical compatibility and/or temperature.
The Kammprofile gaskets are manufactured with two types of core profiles: DIN and the more commonly used “shallow profile”.
