Material selection
The choice of materials is dependent on
the metallurgical requirements, specific
circumstances, media etc.
The following table lists the material
grades preferably used by the aircraft and
aerospace industry.

Cleaning and packing
The requirements for cleanliness of the
piping components for the aircraft and
aerospace industry are very high. Therefore
BUTTING produces the relevant piping
components in a separate workshop.
In order to guarantee freedom from internal
surface irregularities and residual and
foreign matters, a visual inspection is carried
out using a video endoscope having a
diameter of 6 mm and a length of 7.5 metres.
If required, the cleaning of the piping
components is carried out in a cleanroom
< Class 100 000 by rinsing using filtered
liquids at a controlled room atmosphere.
It is possible to determine the purity of
the rinsing agent, i. e. quantity and size
of the particles in accordance with the
relevant requirements, as well as the non
vaporizable residual matters of the testing
Inspection/measuring equipment for ARIANE 4,
PAL-BOOSTER piping
Inspection/measuring equipment for
upper stage simulation model ARIANE
5, EPS-piping
Despatch of piping components using special containers
liquid used, and a relevant test report can
be provided.
The cleaning of the piping components is
followed by drying. For this purpose the
components are evacuated and flushed
with filtered dry nitrogen (2 microns).
The proof of freedom from alcohol is provided
as well.
After completion of the testing, inspection
and cleaning, the material can be packed
under cleanroom conditions using sabotage
safe packing in accordance with the
customer`s instructions and requirements.
The traceability of all handling and cleaning
operations, including packing of the
piping components is thus ensured.
