BS EN 13348:2016 Tubi di rame medicale sgrassato
BS EN 13348:2016 Tubi di rame
Si tratta di uno standard europeo e britannico relativo ai tubi di rame rotondi senza saldatura in rame e leghe di rame per gas medicali o applicazioni sottovuoto.
Il British Standard è l'implementazione nel Regno Unito della EN 13348:2016 ed è stato pubblicato sotto l'autorità dello Standards Policy and Strategy Committee il 30 giugno 2016.
Lo standard europeo è stato approvato dal CEN il 28 febbraio 2016, i membri del CEN come Austria, Belgio, Bulgaria, Finlandia, Francia, Germania, Grecia e così via sono tenuti a rispettare questo standard. Esistono tre versioni ufficiali, tra cui inglese, francese e tedesco.
I tubi di rame conformi a questa norma europea sono adatti per saldatura capillare, brasatura o assemblaggio mediante compressione meccanica o raccordi a collare.
Applicazione
La presente norma specifica i requisiti, il campionamento, i metodi di prova e le condizioni di consegna per i tubi di rame .
Gamma di dimensioni: diametro esterno da 6 mm fino a 219 mm inclusi
Tubi di rame tondi senza saldatura per sistemi di tubazioni sottovuoto o distribuzione dei seguenti gas medicali destinati ad essere utilizzati a pressioni di esercizio fino a 2000 kPa:
- ossigeno, protossido di azoto, azoto, elio, anidride carbonica, xeno;
- aria medica
- miscele specifiche di questi gas sopra menzionati
- aria per l'azionamento di strumenti chirurgici
- gas e vapori anestetici
Requisiti del materiale in rame
La composizione del tubo di rame deve essere conforme a quanto segue:
Cu+Ag: min. 99,90%
0,015% ≤ P ≤ 0,040%
Il grado di rame è designato Cu-DHP o CW024A, uguale al grado di rame americano C12200 e al grado di rame cinese TP2.

Notes:
- EN13348 does not require hardness figures in parentheses, the datas are given for guidance purpose only
- 1 MPa is equivalent to 1 N/mm²
- Tolerances for copper pipes with a nominal outside diameter higher than 108mm in material condition R220 (annealed temper) are not specified.
- Half hard temper refer to straight lengths copper pipes only
Dimensions and tolerance of copper pipe
Dimensions could be supplied upon agreement between the copper pipe buyer and supplier. However, EN13348 has provided standardized nominal outside diameters, nominal wall thickness, and nominal lengths.

Notes:
- Tolerances for copper pipe in R220(annealed) material condition are applicable only to mean diameter
- In case of dispute, to improve the accuracy when determining the mean diameter, the tube may be re-rounded before measurement
- Tolerances for tubes with a nominal outside diameter higher than 108mm in material condition R220(annealed) are not specified.
- a: including 6mm
EN13348 provides copper pipe's wall thickness tolerances in percentage of the nominal thickness,
Nominal outside diameter d, mm | Tolerance on wall thickness (e) e＜1mm, % | Tolerance on wall thickness (e) e ≥1mm, % |
|---|---|---|
| ＜18mm | ±10 | ±13 |
| ≥18mm | ±10 | ±15a |
Notes:
- Concentricity (uniform of wall thickness) of copper pipe is controlled by tolerance on wall thickness.
- a: ±10% for R250(half hard) copper pipes of 35mm, 42mm and 54mm diameter with a wall thickness of 1.2mm.
Surface quality of copper pipe
To avoid contamination of the gas passing through the pipeline and avoid contain any detrimental residue, Winland's medical copper pipes are clean & smooth of inner and outer surface of the tubes.

Terms and definitions
Seamless round copper pipe
Pipe made of copper, hollowed semi-finished product, circular in cross-section, having a uniform wall thickness, which at all stages of production has a continuous periphery.
Brazing
Joining process using filler metal with a liquidus temperature above 450℃
Mean Diameter

Marking of copper pipe
Example:
Copper tube EN13348 - R290 12 x 1.0
The copper marking starts with product name "copper tube", following standard name "EN13348", then the copper product temper "R290", and end with copper pipe's dimensions, or outside diameter & wall thickness.
Ordering copper pipe with Winland, please specify the marking, we use black ink to mark the content, which follows instructions of clients. For permanently marking, Winland will charge a marking cost.
Packing of copper pipe
Winland supplies EN13348 copper pipes of capped or plugged at both ends, in order to maintain the tube's internal cleanliness under normal conditions of handling and storage.
Further more, to ensure the straight copper pipe's fine condition after long distance transportation, Winland offers wooden case packing for each bundles of copper pipes.
Per i tubi in bobina di rame, Winland sigilla i tubi in plastica e, se necessario, mette le bobine su pallet o scatola di cartone.
