Definition and purpose of gasket sheets

Gasket sheets are fundamental elements in engineering and construction that are used to create an effective seal between two surfaces, preventing the leakage of fluids, gases or the entry of contaminants. They act as a sealing component, thus allowing the correct operation and durability of equipment, pipes, structures and construction systems.

These sheets can be made of different materials and have various configurations depending on the specific application, the type of fluid or gas they must contain, the service pressure and temperature, as well as the environmental conditions to which they will be exposed. Its main function is to guarantee the integrity and safety of the joints, avoiding problems that could lead to structural failures or operational losses.

Metal materials

Gasket sheets made of metallic materials are used in applications where high mechanical and thermal resistance is required. These materials include stainless steel, copper, aluminum and special alloys that offer good corrosion and pressure resistance.

The use of metals allows the creation of joints that withstand high temperatures and aggressive environments, such as in petrochemical plants, industrial plants or in steam systems. In addition, metal sheets can be designed with specific geometries to improve sealing, such as spiral joints or with inserts of other materials for greater tightness.

Another advantage of sheet metal is its durability and ability to withstand thermal cycling and fluctuating pressures, making it ideal for critical applications where sealing failure can lead to serious consequences.

Non-metallic materials

Non-metallic gasket sheets are composed of materials such as elastomers, graphite, fibers, rubber, PTFE (polytetrafluoroethylene) and composite materials. These materials offer excellent flexibility, adaptability and chemical resistance properties, making them suitable for sealing irregular surfaces or where corrosive fluids are handled.
