3. Heat treatment:
If specified, we are equipped to carry out heat treatment of bends plus min. **0 mm of leg.
· Furnace is computer controlled and all data is recorded.
· We use an argon protective atmosphere inside the tubes.
· We can provide all types of annealing: Solution; Stress relieving; Stabilization

4. Technical parameters:
OD *2.***8 mm
Bending radii from 1.5xOD up to ***0 mm. Minimum bending radii for OD′s over *8 mm after agreement.
Leg length min. 1,**0 mm
Leg length max. *2,**0 mm
Heat treatment for radii up to 1,**0 mm

5. Technical standards for bending:
Other specifications or special requirements available upon request. Copies of common standard specifications are available on request.

6. Hydrotesting:
· After heat treatment all U-tubes are hydrotested.
· Minimum holding time at the required pressure is 5 sec.
· All tubes are dried and carefully cleaned after testing.

7. Measuring, cutting, deburring, cleaning:
· U-bends are measured exactly in accordance with relevant standards, or to customer’s specification.
· All tubes are cut to the specified leg lengths, ends are deburred and the tubes are internally cleaned with air.
· Before packing, both ends are capped with plastic caps.
