Important Precautions for correct dimensioning

Due to the gradual prohibition of the use of asbestos in the sealing elements, there were several alternatives for its replacement and it caused the need for a deeper understanding of different types of materials that are now used.
While asbestos was extremely flexible and adaptable, new materials, more specific, however they do not tolerate mistakes sizing and installation. On the other hand, These new materials - such as laminated graphite and modified PTFE - have guaranteed quality seal gains in emissions to the environment.
both, Klinger provides the most complete range of hydraulic cardboards. The sealing strip line KLINGERSIL® They consist of materials with synthetic and natural fibers and meet the general industry applications.
The products KLINGERGRAPHIT® They have graphite seal with high purity, and offer high resistance and safety for applications subject to high pressures and temperatures.
Already based seals PTFE modified (KLINGER TOP-CHEM®) and PTFE expandido (staff), They offer high chemical resistance and are ideal for systems exposed to acids, or corrosive contaminants.

The secret of tightness
Every good seal must have an appropriate relationship between the different elements that comprise it (fibers, chemical products, Additional rubbers and), so that it is reliable in every application.
Like this, for the gasket to operate efficiently, is essential apply appropriate surface pressure during the installation. Thus the system will have good tightness keeping however the flexibility.
Likewise it is also necessary to observe the pressure and working temperature of the process and the correct type of sealing material to be used.

Avoid installation errors

For greater efficiency and lifetime joints, try to avoid the following common mistakes:
• Follow established standards for asbestos-containing materials in the selection of asbestos materials. This causes them to use together with greater thicknesses than necessary;
• Apply incorrect torque values ​​- The correct surface pressure applied to the joint is important that the seal operates efficiently. In addition, the screws must be tightened crosswise with steps 30%, 60% and 100% of the nominal torque.
• Inadequate screws - all screws must be equal, Flange according to the standard used.

Software helps select seals
The KLINGER provides its users with the program KLINGER Expert, allowing you to select easily and practical way the materials to be used in seals applied to valves and other pressure vessels. The software calculates and displays the optimal design considering all the points that influence the sealing performance. It's possible to identify the type of flange seal that influence the performance, the class of screws, Recommended torque values, etc. The program shows including graphics, which material and surface pressure more suitable for the best performance and durability of the gasket.
