Advantages of Static gaskets LATTY
LATTY cut gaskets are manufactured according to the specific dimensions, standards, or drawings of each installation. Thanks to our cutting capabilities and material expertise, we offer custom solutions guaranteeing reliable and durable sealing in the most demanding industrial environments.
- Custom cutting according to drawings, standards, or samples
- Wide choice of materials adapted to temperature, pressure, and chemical compatibility constraints
- Manufacture of standard gaskets or complex geometries
- Specific solutions for the nuclear, chemical, petrochemical, and energy sectors
- Patented LATTYmultirating Design innovation to reduce stock references
Manufacturing adapted to your operating constraints
The primary function of a cut gasket is to ensure sealing between a liquid or gaseous fluid and the atmosphere while maintaining its performance despite the mechanical, thermal, and chemical constraints of the installation.
Our range of industrial sealing gaskets provides solutions for numerous applications. Whether for gaskets intended for piping flanges in the oil or chemical industries, valve bodies for gas networks, or pump bodies for the chemical industry, GROUPE LATTY systematically offers a suitable industrial sealing solution.
Similarly, the selection and performance of an industrial sealing gasket depend on very specific criteria: temperature, pressure, fluid type, various constraints (vibrations, water hammer, cycles), and finally, thickness.
The strength of a network of gasket cutting specialists
To ensure the marketing and cutting of gaskets, GROUPE LATTY relies on a dense network that perfectly masters the characteristics and applications of LATTY sealing gaskets.
This network allows GROUPE LATTY to offer its clients, both in France and internationally, a gasket cutting service that matches the quality of its products. Our partners market and cut gaskets of all shapes and materials according to the specific needs of our clients.
Specific solutions for nuclear applications
A long-standing partner of energy production players, GROUPE LATTY offers a range of cut gaskets and materials approved for nuclear applications. These solutions meet the qualification, purity, and reliability requirements imposed by this particularly demanding sector.
Beyond standard gaskets, our cutting capabilities allow for the rapid manufacture of custom gaskets in all shapes and dimensions. Our technical teams also assist users in defining gasket characteristics to optimize sealing performance and equipment lifespan.
LATTYmultirating Design: a patented innovation
The LATTYmultirating Design concept represents a major evolution in flange gasket management.
For the same nominal diameter, ASME B16.5 or EN 1092-1 standards impose several pressure classes associated with different outer diameters and bolt hole patterns. Traditionally, this requires multiple gasket references.
Thanks to its patented geometry, the LATTYmultirating Design gasket allows a single reference to be used for multiple pressure classes. This innovation reduces stock, simplifies maintenance operations, and limits the risk of errors during assembly.
Frequently asked questions about Static gaskets
What is the difference between a flat gasket and a gasket sheet?
The gasket sheet is the base material. The cut gasket is obtained after cutting this sheet according to a precise geometry that meets the dimensions and constraints of the application.
What parameters are necessary to define a cut gasket?
To best determine the most suitable sealing gasket for its clients’ needs, LATTY technical teams have developed internal software to respond quickly to your requests.
Therefore, certain data are essential for processing requests: Temperature, pressure, fluid, flange dimensions, tightening conditions, operating cycles, and mechanical constraints are indispensable for selecting the appropriate material and design.
What materials can be used for cut gaskets?
Gaskets can be made from aramid fiber, carbon/aramid, PTFE, expanded graphite, metal/graphite, technical elastomers, or specific materials for critical applications.
Can you manufacture custom gaskets?
Yes. GROUPE LATTY manufactures cut gaskets from drawings, standards, sketches, or samples, in a wide range of dimensions and thicknesses.
In which sectors are LATTY flat gaskets used?
Our gaskets are used in the chemical, petrochemical, energy, nuclear, food, pharmaceutical, and paper industries, as well as in steam networks and fluid treatment facilities.
