Maxiprofile (Kammprofile)

The Klinger Maxiprofile is a composite gasket, which utilises a serrated metal core with a soft facing material.

The metal core is machined on each contact face with concentric serrations which provides high pressure areas, ensuring that the soft coating flows into any imperfection in the flange even at relatively low bolt loads.

The result is a gasket, which combines the benefits of soft, cut material with the advantages of seal integrity associated with metallic gaskets.

Expanded graphite is the most common facing material used for Maxiprofile gaskets. However, other materials can be used, such as PTFE for chemically aggressive duties or mica for high temperature.

General Properties of Maxiprofile (Kammprofile) Gaskets:

• Maxiprofile gaskets have a wide range of seating stresses under which the seal is effected and maintained
  
• Maxiprofile can be used when there is insufficient bolt load to seal conventional gasket materials
  
• Easy to handle and fit
  
• Maxiprofile Gasket is suitable for a wide range of operating conditions
  
• The soft facing layer prevents damage to the flange
  
• Provide a high integrity seal including thermocycling and shock loading conditions
  
• Sealing is not sensitive to uneven bolt loading conditions

• Maxiprofile Gasket can be refurbished with a new facing layer and reused.
•  

Applications of Maxiprofile (Kammprofile) Gaskets:

• Heat Exchanger and Vessel applications
  
• High and low temperatures
  
• Pressures of up to 250 bar
  
• Low bolt loads
  
• Small flange widths
   
• Damaged flanges

Maxiprofile Core Design

Standard core design is parallel which offers the advantages of even stress distribution across the gasket face. Convex Maxiprofiles are also available which have a reduced depth of grooves towards the profile centre.

This type of profile ensures a high seating stress in the middle of the profile and is effective for low bolt load applications.
