Tube Diameter	Wall Thickness	Bending Radius	Straight Leg Length	Tube Length before Bending
9.52 / 31.75 mm 0.37 / 1.25 in	0.70 / 3.40 mm 0.027 / 0.133 in	Min. 1.5 mm x OD 0.06 in x OD	Max. 13300 mm 523.6 in	Max. 30000 mm 1181 in

For different technical specifications, please feel free to contact us. Together we can find the most suitable solution.

Our company meets the generally required standards for determining U-bend tolerances, namely:

ASTM A556/556M
ASTM B395/B395M
ASTM A688/688M
ASTM A803/803M
TEMA Section 5 § RCB 2.31
DIN 28179

After the bending, which is a cold processing, heat treatment of the bending portion can be requested.
Pantani Divisione Tubi is equipped with two heat treatment machines and a nitrogen generating machine, which is used especially in the treatment of stainless steel tubes to protect their inner surface. Upon request, it is possible to carry out a pickling process or mechanical removal of browning after the heat treatment.

The following table shows the tube dimensions for which heat treatment can be carried out:

Tube Diameter	Wall Thickness	Center-to-Center Distance
9.52 / 31.75 mm 0.37 / 1.25 in	0.70 / 3.40 mm 0.027 / 0.133 in	Max. 2300 mm 90.55 in
