Tgi Ilmadur Transparent Gauge Glasses

We are engaged in manufacturing, distributing and exporting excellent quality TGI ILMADUR Transparent Gauge Glasses to our valuable clients. Gauge Glasses are designed for continuous service temperature up to 280A C. Temperatures exceeding 280A C 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 300A C, or about 70% for service temperature up to 320A C. The reduced compressive stress will also decrease the thermal shock resistance of the glasses. However, in some special cases depending on the actual service conditions (pressure, temperature, kind of media, kind of frame) it may be possible to use the TGI Ilmadur Transparent Gauge Glass for temperatures higher than 280A C.

TGI Ilmadur Transparent Gauge Glasses (e.g. width 34mm) can be used for media with no significant glass attack (e.g. oil, hydrocarbon) under the following service conditions.

pressure (bar)temperature (A C)
34535
290120
180400
For media with significant glass attack (e.g. saturated steam, alkali) we recommend the use of TGI Ilmadur Transparent Gauge Glasses along with protective mica shields for service pressure >35 bar.

In any case the Service Operator has to check the actual and expected datas for the process, Gauge Glasses are used for.
