The PTFE filler provides superior chemical resistance and sealabining with strongly corrosion resistant metals, it can be applied for corrosive fluids, pure oxygen gas and vacuum lines.     Feature 1. Sealability is superior to that of other SWG gasket. Usage is possible even with vacuum lines. 2. Excellent corrosion resistance makes it suitable for almost all types of fuild by selecting appropriate hoop materials. 3. Not used for glass or rubber lined flange, glass or porcelain flange.   Service Range fluid Maximum service temperature °C Maximum service pressure Water type fluids 300 Class 600 Oil type fluids 300 Class 600 Gas type fluids 300 Class 600   GRAPHITE SPIRAL WOUND GASKET SL NO.: G400 SERIES     The gasket uses expanded graphite tape as the filler material which provides superb sealability even under severe conditions such us high temperature, high pressure, cryogenic temperatures, heat cycles, temperature cycles and so on.     Feature 1. Sealing, especially gas sealing, is superior to that of asbestos gaskets. 2. Little deterioration of the filler material at high temperatures, outstanding long-term sealability even under high temperatures and high pressures. 3. Sealing remains outstanding even under servere conditions such as pressure fluctuations and heat cycles. 4. Excellent sealability is maintained making it possible to apply this for corrosive fluids by selecting the appropriate materials. 5. Outstanding sealing even at cryogenic temperatures.   Service Range fluid Maximum service temperature °C Maximum service pressure Water type fluids 450(650) Class 2500 Oil type fluids 450(800) Class 1500 Gas type fluids 450(800) Class 1500 Cryogenic temperature fluid -240 20 Mpa Notes: The values in brackets() are maximum service temperature under a non-oxidizing atmosphere. When using with RF flanges in open air, the Max. service temperature is 450°C.   01    02    03     04       　 Copyright © SinoSeal.com  All Rights Reserved.  TEL: 0086-571-82372789　 82371789 FAX: 0086-571-82376833　 E-mail: info@sinoseal.com ADD: B-901, TAIGU GUANGCHANG, JINCHENGLU 451 HAO, XIAOSHAN,HANGZHOU,ZHEJIANG,CHINA. 浙ICP备05084306号
