U-benttubes are widely used in heat-exchanger systems. Heat-exchanger equipment on the basis of seamless stainless U-tubes is essential in strategically important and critical fields — nuclear and petrochemical machine building.
A tube-bending line, that was installed at Centravis in the end of 2007, allows to produce U-tubes as per such standards:
1. ASTM A688/A688M
2. ASTM A803/A803M
3. ASTM A556/A556M, ASME SA-556
4. ASME SA-688
At present the company has purchased the equipment for production of the following product range:

A maximum lengths of straight part is 12 500 mm
The range of lengths of straight tubes before bending is 14 000 — 26 000 mm
