Tubes and cylinders

Standard size range

Large diameter tubes are sometimes called cylinders. The standard tubes sizes are given below. Choose the right outer diameter (OD) range and get to know the other data (available wall thickness (WT), weight, etc.)

The standard tube length is 1500 mm, but we can supply tubes of different lengths.

Below were reminded properties of DURAN glass described on page Borosilicate glass in section Our offer/Technical glass /Types of materials

DURAN® - DIN 7080

It is a glass highly resistant to water, neutral and acidic environment, solutions and concentrated acid and alkalies, chlorine, bromine, iodine and organic substances. The chemical resistance of the glass Duran® resistance is higher than most metals, even during a prolonged period and at higher temperatures (> 100 ° C). Only hydrofluoric acid, concentrated phosphoric acid, and strong alkaline materials may cause   decrease the surface of glass (glass corrosion) of temperature above 100 ° C.

Maximum working temperature of glass DURAN® is 500 °C. At temperatures above 525 ° C, glass begins to soften, and a temperature above 860 ° C liquefies. May be cooled to a very low freezing temperatures and is therefore suitable for use in contact with liquid nitrogen (about -196 ° C). In general DURAN® products are recommended for use down to - 70 °C, while defrosting must be ensured that the temperature difference does not exceed 100 K.

DURAN® glassware is suitable for use in microwaves.

DURAN® glass is highly resistant to changes of temperature  (ΔT = 100 K). Thanks to the very low coefficient of linear expansion (3.3 x 10-6 1/K) in the articles of this material in practice there are no stresses during rapid temperature changes (e.g. not crack the vessel when filled with boiling water).

DURAN ® is a commercial version 3.3 borosilicate glass, hence the majority of the properties and composition is similar to the type of glass.

Chemical resistance

Due to the high content of silica (SiO2), DURAN glass is very resistant to water, acids, organic solvents and halogens. Only hydrofluoric acid, hot concentrated phosphoric acid and strong alkaline solutions cause significant corrosion of the glass. 

Hydrolytic resistance
