novaphit® - high-pressure gasket material made from expanded graphite for maximum safety requirements.

Why using graphite as gasket material? Following the substitution of asbestos, no technically reli- able solutions were available initially for gasket applications in highertemperature ranges. Rubber-bonded gasket mate- rials have a natural maximum temperature limit.There was a particular need for better solutions for media that are hot, dangerous and have creep properties, such as steam or heat transfer oils.This was the reason for the tremendous success of gaskets made from expanded graphite. Properties of novaphit® gaskets made from expanded graphite • Suitable for temperatures between...

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...

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-resis- tant expanded metal insert made from chrome-nickel steel Expanded metal made from acid-resistant stainless steel Corrosion- and acid-resistant material (AISI 316L). 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 of which chambering of the gasket...

The TÜV-certified solution for oval This gasket, which is based on the classic novaphit® SSTC material, has become the widely used standard product for oval gaskets that require official approval sinceTÜV testing was introduced in connec- novaphit® SSTCTRD401 satisfies the requirements made in the highest testing category D (250 °C/40 bar) specified in TRD 401 without any difficulty. It can, however, also be used when the application parameters are more deman- ding than this (see the application recommendation below). Oval gaskets 2,4 or 6 mm thick are produced from the basic material,...

Technical information Application recommendations, depending on the pressure and temperature The application recommendations for different temperature and pressure levels in the graphs apply to a gasket thickness of 2.0 mm and with smooth flanges. Higher limits are possible when thinner gaskets are being used! Application recommendation for water/steam Application recommendation for other media* Cold compressibility * Example for the most common other media. Precise data for individual cases can be found in the Frenzelit novaDISC program or you can contact our application engineering...
