Cleanliness and Resistance
In the sensitive healthcare areas and installations, it is imperative to use materials that safeguard cleanliness, neat appearance and durability. Schönn copper tubes, can withstand high operating pressures with unlimited durability, thanks to the naturel strength of copper, hence they are the ideal choice for the construction of medical gases distribution networks. Schönn copper tubes are manufactured according to the requirements of standard EN 13348. They are supplied with end caps to prevent contamination by foreing matter intrusion during storage or transportation.

Non-arsenical copper phosphorus deoxidised (DHP-Cu) with minimum copper content 99,90 % and P= 0,015% - 0,04%.

Medical Gas Pipes
The piped distribution system shall use copper pipes manufactured from phosphorous deoxidised non-arsenical copper to EN 1412:1996 grade CW024A (Cu-DHP), manufactured to metric outside diameters and having mechanical properties in accordance with EN 13348:2008 - R250 (half hard) for sizes 12-28 mm, R250 or R290 for sizes 35-54 mm and R290 for larger sizes of 76mm and above. Pipes shall be degreased suitable for oxygen use and cleanliness is to be maintained by filling each pipe with dry, clean, oil and oxygen free nitrogen, fitting suitable end caps and protectively wrapping. All pipework materials shall be manufactured by EN ISO 9001:2008 registered companies.

pipe ENmm

For sizes up to 54mm, copper pipes shall be permanently and durably marked at regular intervals along its length with the following information;

a) The harmonized standard number EN 13348,
b) DIN kitemark/statement/equivalent approval,
c) Temper designation to EN 1173,
d) Manufacturer’s identification,
e) Date of production: Year and month (1 to 12)
f) Confirmation of degreasing for oxygen.


Following installation, pipelines shall be clearly identified with 150mm wide adhesive labels. Labels shall be fitted near walls, rivers, valves, and junctions. Colour coding and labelling shall be in accordance whir BS 1710:1984. Arrows to identify the direction of gas flow shall be fitted adjacent to each identification label.

Identification of Medical Gas Pipelines
Pipeline should be identified in accordance with 1710:1984, and colour banding for the pipelines should be used. Colour band identification should be applied every 3 m. and bearing 6mm size letters should identify each gas. Self-adhesive plastic labels of approved manufacture may be used for his purpose. A band 150 mm wide is usually adequate all color - coded tapes applied by the pipe manufactures should be removed before the systems are identified, in accordance with this paragraph.

Care should be taken to maintain pipeline identification when periodical re-painting is undertaken. The direction of flow should be indicated.
