This includes pressure vessels subjecteddimensional tolerances are guaranteed byto thermal and chemical stresses and liquid level gauge application.production and quality controls. With theseexceptional safety characteristics, MAXOS A high safety level is secured through the use of special borosilicate glass of highsafety sight and level gauge glasses canchemical durability, exceptional purity and homogeneity. The low thermalbe used under extreme operationalexpansion of our SUPRAX 8488 borosilicate glass, combined with thermalconditions. It is therefore mainly theseprestressing (tempering) creates a high resistance to sudden temperature changes.safety aspects which influence responsibletechnicians again and again to chooseMAXOS .2

Schott 03063 MAXOS E RZ.fh8 15.05.2003 15:26 Uhr Seite 5MAXOS Long form level gauge glasses,reflex and transparentTechnical characteristicsBending strength is determined by thesurface compressive stress and the inherentresistance of the glass. The inherentresistance is heavily dependent upon thesurface quality.For safety reasons, the stress to the glassescaused by internal forces, thermal stressand vessel pressure have to be totallyabsorbed by the surface compressive stressso that a tensile stress of the glass surfaceis prevented.Special tempered MAXOS glassesunder polarized light.Application conditions5700 psi345 barMaximum permissible Maximum permissibletransparentreflex4750 psi328 barpressure4500 psi310 bar4250 psi293 bartemperaturebarpsi C 004146,00038100Saturated steam or hot water in direct contact4000 psi276 barwith reflex or transparent sight glassesPressure psi and bar3750 psi259 barSaturated steam or hot water in contact with3500 psi241 bartransparent sight glasses protected with mica3250 psi224 bar3000 psi207 barNon-corrosive, non-steam service and no2750 psi190 bartechnically significant glass attack, with reflex ortransparent glasses100 F38 C188 F 275 F87 C 135 C363 F184 C450 F232 C538 F281 CTemperature in C and FTransparent sight glasses in contact with mediaswith no technically significant glass attackPressure temperature graph for MAXOS glasses.Range of application with no technically significantglass attack.4High pressure transparent sight glassesin special armatures (gauges)
