Gasket Sheets

Grafex - Graphite Sheets

Expanded graphite is used in high temperatures and has a very good level of chemical resistance. It is a soft material that has a better compression rate than gaskets made out of fiber mixtures, thus assuring a higher level of tightness.

Gaskets

Grafex - Flat Gaskets

After choosing the right type of gasket sheet suitable for your application, this is processed by stamping or cutting, thus obtaining the desired flat gasket. When choosing the right material, one must take into consideration the working temperature (peak and under continuous operation temperature), pressure, working environment and other critical conditions specific to the application.

Grafex - Grafoil Type Rings

Grafoil type rings are manufactured using a specific technology, from graphite by centrifugation or compression molding. What is characteristic of these type of rings is their small section and small tolerances when fabricated small dimensions.

Grafex - Spiral Wound Gaskets

Semi-metallic gaskets are used for applications that require an increase in temperature and pressure, and high loads on the flanges. The most often used semi-metallic gasket for high-pressure joints is the spiral wound gasket. Spiral wound gaskets are manufactured by winding an alternating combination of a metal strip and soft filler material. The material is to be selected in order to fit the application – Teflon or graphite, dependent on running parameters.

Grafex - Model GG - Grooved Gaskets

Grooved Gaskets GG (kammprofile) are manufactured from a metal core with concentric grooves on both sides, covered with sealing material on both sides. The grooved gaskets can resist to pressures of up to 350 bar and temperatures of up to 800°C, depending on the sealing material type. Their application is for difficult sealing environments where performance is critical or where sealing stresses are low.

Grafex - Model CG CG - Corrugated Gaskets

Corrugated gaskets CG CG are manufactured from a core of profiled metal plate in order to ensure the rigidity and durability of the gasket. The shape of the profile and the thickness of the gasket depend on the diameter and width of the gasket. Graphite layers can totally cover the metallic profile or, by request, just the inside part so that the gasket could also have a centre ring.

Other Products

Grafex - Braided Packings

Braided packings are generally used for valves stuffing box and pump shafts for various liquid and gaseous mediums.

Grafex - Flange Insulation Kits

The standard kit consists of:

Grafex - Model GC - Friction Gaskets

Friction gaskets are manufactured from non-asbestos material, shaped according to the customers’ specifications or under the form of a plate. The mixing and compression technologies help obtain a homogenous and reliable material, with a high degree of friction, in a wide variety of temperatures, with a reduced uniform depreciation and a silent and stable operation. The usage of aramid fibres provides the proper maintaining of elasticity and resistance to cracking.
