High-pressure gasket material made from expanded graphite for maximum performance and perfect handling. novaphit® SSTCTA L and novaphit® AAST TECHNICAL TEXTILES EXPANSION JOINTS

Environmental protection optimised by gaskets of maximum quality throughout the company High-quality gaskets make a major contribution to protec- tion of the environment. Rules like the German regulations about air pollution ("TA Luft") specify demanding sealing criteria. It is particularly important that these criteria are met in applications involving media that endangerthe envi- ronment and are harmful to health. Demonstration of the high quality of novaphit® AAST and novaphit® SSTCTAL in component testing The component test involves leakage measurement following 48 hours of exposure to a...

High-quality graphite gaskets made from high-quality graphite novaphit® gaskets made from expanded pure graphite are suitable for high chemical, thermal and mechanical stresses. They do their job reliably even when there are extreme fluc- tuations in conditions, novaphit® gaskets do not contain any bonding agents, incidentally. There can be substantial differences in the quality of expanded graphite. An explanation is given below of how expanded graphite is made and what criteria need to be Where does graphite come from? Graphite is obtained in both open-cast and underground mines. The choice...

Material profile of novaphit® SSTC Advantages of the expanded metal insert used Gasket material made from expanded graphite (purity level 99 %) with internal impregnation and an acid-resistant expanded metal insert made from chrome- nickel steel (material no. 1.4404 / AISI 316L). Expanded metal made from acid-resistant stainless steel Rust- and acid-resistant material (material no. 1.4404). Thickness of the expanded metal insert used Stretching the stainless steel film used (original thick- ness 0.15 mm) leads to a three-dimensional structure with a projected height of about 0.4 mm, as a result...

Material profile of novaphit® AAST Advantages of the unique combination of expanded metal and smooth metal inserts Multilayer gasket material made from expanded graphite (purity level 99.5%) with several expanded metal and smooth metal inserts made from stainless steel (material no. 1.4404 / AISI 316L) and intelligent internal Excellent handling Thanks to the multilayer structure, gaskets made from novaphit® MST have extremely good dimensional stability properties and do not buckle.This can be an advantage over single-layer, reinforced graphite gaskets. Outstanding adaptability The logical arrangement...

Technical information Application recommendations, depending on the pressure and temperature The application recommendations for different temperature and pressure levels in the graphs apply toa gasket thickness of 2.0 mm and with smooth flanges. Higher limits are possible when thinner gaskets are used! Application recommendation for water/steam Application recommendation for other media* Cold compressibility novaphit® SSTCT^ * Example for the most common other media.
