Pre-stressed DURATAN® special glass tubing

With DURATAN^®, SCHOTT shows its expertise in glass for demanding applications. Borosilicate glass tubing is based on the well known DURAN^®, and a thermal toughening process additionally pre-stresses the tube wall. The pre-stressed glass is thus two to three times more resistant to tension and mechanical shock than untreated glass. Since the diverse features of DURAN^® are preserved, DURATAN^® also provides advantages over plastics such as high scratch resistance and light stability, high resistance to UV radiation, as well as high chemical resistance and temperature-change resistance.

These features make DURATAN^® ideally suitable for exterior applications such as:

Safety lights in explosive atmospheres
Sight glasses and display cylinders for product presentations
Sight glasses in pipeline construction
Tunnel lighting
Outdoor lighting
Interior and exterior architecture
Art and design

Hardened glass provides enhanced safety: If damaged, it shatters into fine fragments, similar to tempered safety glass. Shock resistance has been tested with ball-drop tests. Upon customer request, we will perform statistically-based strength tests on defined tube dimensions.

Tube diameters of 100 - 150mm, tube lengths of 300 to 1,300mm and wall thicknesses of 5 to 9mm are standard dimensions for DURATAN^® glass tubing. More sizes are available upon request.

You can find additional information and technical data in our brochure and in our Glass Tubing Explorer under the key word DURATAN^{^®}.
