 Application
Gauge glasses are designed for continuous service temperatures up to 280℃.
Temperature exceeding 280℃ may cause the induced compressive stress to be relieved, reducing
it to approximately 90% of its initial value following a service of 300 hours at 300℃,  or about 70% for
service temperature up to 320℃.

TGI Ilmadur Gauge Glasses (e.g. Transparent type, width 34mm) can be used for

Media	Pressure (bar)	Temperature (℃)
Media with no significant glass attack (e.g. oil, hydrocarbon)	345	35
	290	120
	180	400

* For media with significant glass attack (e.g. saturated steam, alkali) we recommend to use
  Transparent Gauge Glasses only with protective mica shields for service pressure ＞35 bar.

* Delivery
   NO.2 and 4 to 11 Reflex & Transparent Type: Stock
