Borosilicate glass 3.3 is a most suitable and a longtime proven material in the chemical and pharmaceutical industry due to its universal corrosion resistance, smoothness and transparency. The special material properties of borosilicate glass 3.3 require specially adapted manufacturing processes providing specific shapes of the connecting glass flanges. Due to the fact that glass systems have been manufactured since decades, numerous different types of glass flanges are still in use and comply with e.g DIN and TA-Luft standards. In the course of our company history 4 glass systems had already been established since the mid-50s. They have been replaced 2012 by the QVF® SUPRA-Line.
The QVF® SUPRA-Line combines the technical advantages of these former glass systems. Furthermore, the QVF® SUPRA-Line permits not only to connect the former glass systems to the QVF® SUPRA-Line but also to interconnect the different former glass systems among each other.
The operation of existing glass plants is secured by the supply of original QVF® spare parts. The different types of PTFE-gaskets suitable for different applications are still available as QVF® standard components.
The range of flange couplings DN15 up to DN1000 with flange rings made of steel or stainless steel is complemented up to DN300 with flange rings made of plastic.
As an example the couplings and gaskets DN25 for the QVF® glass systems QVF® WPR and QVF® SUPRA-Line are shown.
