$Category: Borosilicate sight glass <o:p></o:p> <o:p> </o:p><o:p></o:p> Given its low coefficient of thermal expansion, borosilicate glass known as borosilicate 3.3, is internationally recognized as the most suitable for the manufacture of most sight glasses for industrial purposes. Borosilicate sight glasses have thermal stability, and it allows their use in temperatures up to 500 º C and up to 550 º C for short periods of time, coupled with its chemical stability that allows their use under severe corrosion.

They are also produced in curved shapes, blasting, steps, and bevels on request. All edges are polished to ensure minimal dimensional tolerance. We can make prints on the glasses, as well, in baked paint or sand blast. REFMEX GL BR flat glass hardly expands under thermal pressure, however it is necessary to use packaging as a shield between the metal box and the glass. It needs to be made of a material resistant to the task required and resistant enough to absorb the metal contractions due to the temperature.<o:p></o:p> <o:p></o:p> <span lang="EN-US" style="line-height: 115%; mso-ansi-language: EN-US; mso-fareast-font-family: Calibri; mso-bidi-font-family: 'Times New Roman'; mso-fareast-language: EN-US; mso-bidi-language: AR-SA; mso-ascii-theme-font: minor-latin; mso-fareast-theme-font: minor-latin; mso-hansi-theme-font: minor-latin; mso-bidi-theme-font: minor-bidi">Besides the working temperature of the borosilicate glass, a relevant factor to consider is the thermal shock, meaning by this the sudden change of temperature, which is expressed as a temperature gradient and for this type of glass is a maximum value of 120 ° K , exceeding this value there are chances to fracture the crystal. <o:p></o:p>$
