For carbon graphite rings you have come to the right place at Qgraphites. We supply custom graphite rings from two categories for various applications: graphite rings for seals and segment rings made of carbon graphite.
The graphite rings in both categories are of high quality and can be produced entirely according to your requirements. Thanks to our many years of experience and versatile expertise in this field, we dare to guarantee that our graphite rings fully meet your specific requirements.
Carbon graphite rings for seals
A feature of Qgraphites seal rings is that they are impermeable to gases and liquids. In addition, they are characterized by the absence of deformation and flexibility. Combined with the fact that these graphite rings are virtually maintenance-free, they are ideal for use in wear-prone seals. Moreover, you can have them fully custom-made with us.
Any geometry and dimension
Our graphite rings for seals are available in any desired ring geometry and in any desired size. Due to its special physical properties, carbon graphite is very suitable for use in seals. Think of pumps, exhaust systems and fittings. In addition, high temperatures and/or aggressive liquids have no adverse effect on the graphite rings of Qgraphites.
Safety
The high quality of our graphite rings ensures that people and the environment are protected against polluting substances, such as gases and liquids. The outer diameters of the graphite rings of Qgraphites are between 3 and 1,150 millimeters. These graphite rings feature beveled surfaces and can be specified by you to inner or outer diameter. In addition, they can withstand pressure heights up to 700 bar.
Carbon graphite segment rings
Like our graphite seal rings, our carbon graphite segment rings are impermeable to gases and liquids. Another characteristic that both graphite rings have in common is that they are virtually maintenance free. This makes segment carbon graphite rings ideal for use with seals that need to last a long time. This ensures that you have as little downtime as possible.
Ideal gaskets for steam turbines
The Qgraphites segment rings made of carbon graphite are the ideal packing rings for steam turbines, among other things. Our carbon graphite is considered the perfect component for high-quality segmented seals. Each and every one of them is equipped with special high-quality materials and precision production. This results in the most optimal sealing. In addition, this also ensures the most optimal lifespan.
High-quality materials
Characteristics of these carbon graphite rings from Qgraphites are the fine grain structure with excellent mechanical properties. The springs or ‘garters’ are made of, among other things, stainless steel. These are therefore suitable for temperatures of more than 370 ° Celsius. The so-called ‘stops’ can also be made of stainless steel. Other materials used for this are cadmium plated steel or bronze.
Precision manufacturing
The sealing effectiveness of our carbon graphite segment rings is achieved through the combination of careful design and pure craftsmanship during production. Qgraphites takes the shaft clearance calculations and the coefficient of thermal expansion into account. This, from both the materials used for the shaft and the selected quality of carbon graphite. The exact temperature height is also taken into account. In short, at Qgraphites you are also assured of the highest quality carbon graphite segment rings. We would like to hear which high-quality graphite ring we can serve you with.
