Range
 

Tubes are produced in accordance with standard UNI EN ISO 10305–3 and 10305-5. Different types of shapes and dimensions can be produced after a feasibility analysis.

External Diameter°

° Tolerances different from the ones showed in the table are agreed with the client.

Thickness (T)

*max + 0.35 mm

Length (L)°

For standard length tube (i.e. from 6.000mm to 6.400mm) the tolerance is +100 -0mm, for non-standard length cut tubes see the following table:

 

° Tolerances different from the ones showed in the table are agreed with the client.

Internal seam

Tube internal seam could be supplied as normal, reduced or fin-cut.


Shape

Tubes with a shape different from the round have normally the following characteristics: 
• welding line is positioned on the short side (A’);
• for tubes with rectangular and semi-oval shapes the minimum edges ray is equal to 2*B.

Different shape tubes are illustrated in the pictures below. Any other peculiar shape can be produced after a feasibility analysis.
