P reci s ion. . .... in glass

SCHOTT Medica GmbH in Wertheim, a subsidiary of SCHOTT Glasin Mainz, has the know-how and the technical equipment at itsdisposal to manufacture glass components at highest precision andwith dimensional tolerances in the micrometer range. As a result, itis possible to achieve a degree of precision for the glass that isequivalent to the precision of metals.

Thus glass tubing is attractive as a versatile material for constructionwhere highest precision is required in addition to

- Excellent resistance to corrosion- Resistance to temperature change- Smooth surface- Transparency and- Chemical resistance.

Tolerances achieved inprocessing glass tubing

Internal diameter (ID)from 0.15 mm ..... 240 mm

Smallest possible tolerance± 0.003 mm(depending on the ID)

Outside diameter (OD)from 2 mm ..... 260 mm

Smallest possible tolerance± 0.002 mm(depending on the ID and wallthickness)

Lengthmax. 1,000 mm

Smallest possible tolerance± 0.05 mm

Manufacturing method

In order to manufacture precision bore glass, DURAN®-tubes areheated under vacuum and then are shrunk onto precisely tooledmandrels. The KPG®-tubes manufactured in this manner have adefined internal diameter. The accuracy depends on the cross-section and the actual bore size.

KPG®-tubes can be manufactured with various cross-sections andaxial sections and they can be processed further in many ways.

Take advantage of our precision and variety

Besides the tight tolerances of the precision boreglass, SCHOTT Medica GmbH offers a largenumber of possible processing methods, for

example processing of the ends of the tubes orof the glass surface. It goes without saying thatthe precision capillaries and the standard tubescan be processed as well.

End processing - cold working

1. Cracked-off or cut

The cut or cracked-off surface has arough texture and sharp edges.Intended mainly for further processing

2. Ground square and parallel andarris edges

The cut surface has got a smoothtexture. Slight arris edges preventthem from spalling during handling.

3. Ground, arris edges inside andoutside, also available fire-polished

Smooth surfaces and edges. Thearris edges provide protection againstchipping and other damage.

4. Ground square and parallel, arrisedges inside and outside, alsoavailable fire-polished

The cut surface has got a smoothtexture. Slight arris edges preventthem from spalling during handling.

5. Ground square and parallel andat right angles to the longitudinalaxis, arris edges, also available fire-polished.

Smooth surfaces and edges. Thearris edges provide protection againstchipping and other damage.

6. Defined special arris edges

The tube ends have arris edges onthe inside and / or on the outside,according to your specifications.

7. External or internal step

According to your specifications,steps are ground on the inside orthe outside of the tube ends.This permits exact centering wheninstalling the tubes.

8. External or internal groundmulti-step

At the ends of the tubes, multi-steps are ground on the inside orthe outside, according to yourspecifications.

End processing - heat working

1. Ends fire-polished and round

After cracking-off or cutting, theends are fire-polished.The result is a very smooth, roundedge.

2. Defined constriction or flare atthe ends

The tube ends are constricted orflared, according to yourspecifications.

Other possible processing methods

The examples given here show only a very small ex-

cerpt from the various possible methods for proces-

sing glass tubes and tube segments. On request we

offer you, for example, different cross-sectional

forms.

Surface treatment

Matt finished surface

A range of finishes at different degrees of roughness

on the inner and/or outer surface can be obtained

via blasting the item using different grain sizes. The

effect of the matt finished surface is an even distri-

bution of light. This finish also provides a more ad-

hesive surface for mastics.

Ground surface

Very tight tolerances (in the µµµµµm range) on the ex-

ternal diameter can be achieved by grinding. This

processing method is used, for example, to produce

samples to an exact fit. According to your specifica-

tions, we will realize different degrees of roughness.

Polished surface

Ground tubes receive a smooth, see-through

surface when being polished. Typical applica-

tions are, for example, cylindrical conveyors or

film carriers.

Plastic coating

When ordering from us, you automatically get

a high degree of safety. A plastic coating war-

rants you an effective protection against cracks

or other damages to the surface.

Physical Data

Calculation of pressure resistance (p)

for a given Wall Thickness (WT)

and a given Outside Diameter (OD)

Calculation of the Wall Thickness (WT)

at a given pressure resistance (p)

and Outside Diameter (OD)

OD = Outside Diameter in mm WT = Wall Thickness in mm

p = Pressure Resistance in bar K/S = Resistance Parameter in N . mm-2

Resistance parameter for DURAN® Borosilicate Glass 3.3: K/S = 7 N · mm-2 as

per EN 1595 Standard: Pressure equipment made from Borosilicate Glass

3.3: General rules for design, manufacture and testing.

Pressure Resistance of DURAN® Tubing and Capillary

Pressure resistance (p) is also influenced by the following:

Difference in temperature between inside and outside wall

Surface Quality

End Finish

Exact calculations are available on request.

Other points to be considered:

AD leaflet N 4, edition 9.83: Pressure vessels made of glass, with encl. 1,

edition 6.85: Evaluation of faults in walls of glass pressure containers

AD leaflet B 1, edition 6.86: Cylindrical and spherial shell under internal

pressure overload

According to ISO 718, the resistance to thermal shock is the difference in

temperature between the hot test sample and the cold water bath (room

temperature) at which 50 % of all test samples show a tendency to crack

when quickly immersed. Resistance to thermal shock of tubing, capillary and

rod is dependent on the wall thickness, the shape and size of the quenched

area, the state of the surface, the stress which may be present and the end

finish. Fast, uneven heating or cooling can easily lead to breakage as a result

of tensile strength. It is recommended not to exceed a temperature

difference of 120 °C. For large wall thicknesses, this temperature is limited to

lower values. Listed below are some measured values to illustrate the

resistance to thermal shock of DURAN® Borosilicate Glass 3.3 tubing and

rod. These should be used only as reference values as considerable

differences between tubing/rod of the same dimensions are possible.

Physical and Chemical Properties

Chemical Composition(main components in approx. weight %)

Chemical Resistance

DURAN® Borosilicate Glass 3.3 is highly resistant to water, neutraland acid solutions, concentrated acids and acid mixtures, and tochlorine, bromine, iodine and organic substances. The chemicalresistance of this glass is superior to that of most metals and othermaterials, even when exposed to long processing periods andtemperatures above 100 °C.

A slight release of mainly monovalent ions takes place afterexposure of the glass to water or acids. A very thin layer ofimpervious silica gel is subsequently formed on the surface of theglass which in turn slows down further attack. Acid, hot phosphoricacid and alkaline solutions attack the glass surface as a function ofconcentration and temperature.

Transmission

Hints on Processing

The excellent properties of DURAN® tubing, capillary and rodprovide for good workability when forming and cutting the glasswith the normal techniques for technical glass. To eliminatetemporary stress as a result of the working process, the glass shouldbe well heated to a maximum temperature of 550 °C and kept atthis level for a maximum of 30 minutes; for a thinner wall only afraction of this period is necessary. In order not to affect thechemical stability of the glass, annealing time should be kept asshort as possible. We recommend the annealing temperatures givenin the table below:

If an article needs to be annealed several times, the sum of allannealing periods at 550 °C should not exceed 2 hours. DURAN®

products can be fused stress-free with borosilicate glasses of thesame type and can be processed and annealed at the sametemperatures. Printing on DURAN® tubing, capillary and rod can bedone with silver copper diffusion and screen-printing dyes.
