3. Heat treatment:
If specified, we are equipped to carry out heat treatment of bends plus min. 150 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 12.7-38 mm
Bending radii from 1.5xOD up to 1250 mm. Minimum bending radii for OD's over 28 mm after agreement.
Leg length min. 1,000 mm
Leg length max. 12,000 mm
Heat treatment for radii up to 1,000 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.
