Pressure Apparatus made from Borosilicate Glass3.3: General Principles for Calculation, Production and
Inspection
Pressure Resistance (P) can be impaired, for example, by the following:
-Different in temperature between inside and outside wall
-Surface Quality; -End Finish; -Tubing Length
-Observance of Conditions of Installation as per Pressure Vessel Regulations.
Resistance to Thermal Shock
2
3. As per DIN 52313, 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 k. For large wall thickness, this
temperature is limited to lower values.

Hints on Processing
The excellent properties of LINUO tubing, capillary and rod provide for good word ability
when forming and cutting the glass with the normal techniques for technical glass. To
eliminate temporary stress as a result of the working process, the glass should be well heated
to a maximum temperature of 550 and kept at this level for a maximum of 30 minutes; for
A thinner wall only a fraction of this period is necessary. In order not to affect the chemical stability of the
glass, annealing time should be kept as short as possible. We recommend the annealing temperatures given
in the table below:

PACKING
Glass tubes are layered into bundles with a square or rectangular cross-section. They are packed into the
geometrically tightest space and then covered at each end with transparent shrink film. Then they are packed
into carton. This means that no movement of the tubing is possible during transportation, so that the package
is more stable and reliable. The shrinks film at each end of the bundle cover each tube and provide the very
best protection against contamination.
