Application of Maxiprofile Gasket
- Standard flanges, Heat exchanger and vessel applications
- High and low temperatures
- Pressures of up to 400 bar
- Low bolt loads
- Narrow flange widths
- Damaged flanges
- Have a wide range of seating stresses under which the seal is effected and maintained.
- Can be used when there is insufficient bolt load to seal conventional gasket materials.
- Easy to handle and fit
- Suitable for a wide range of operating conditions.
- The soft facing layer prevents damage to the flange.
- Provide a high integrity seal including in thermo cycling and shock loading conditions.
- Can be refurbished with a new facing layer and reused.
- Can be manufactured in a very wide variety of sizes and shapes according to customer design
Styles of Maxiprofile’s available.
All can be supplied with bars to suit heat exchanger configurations.
CA1,2&3 Convex profiled joints in the same style as LA 1, 2 and 3. The convex profile is designed to assist sealing in bolt load applications.
Lateral profiled joint with guide ring for raised and flat face applications
Lateral profiled joint without guide ring for male and female, tongue and groove and groove flanges
Lateral profiled joint with floating guide ring for raised and flat face applications.
Standard core design
The core design for the standard Maxifrofile style 109 is parallel and shown below
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 duties.
