Tubes, U-Bending Available)
Bending radii from 1.5 X OD up to 1250MM. Minimum bending radii for
OD′s over 28MM after agreement.
Leg length min. 1,000MM
Leg length max. 12,000MM
Heat treatment for radii up to 1,000MM
Other specifications or special requirements available upon
request. Copies of common standard specifications are available on
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.
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.
In strong, open or closed, wooden boxes depending on destination -
max. 8,000 kg.
Ends of tubes protected by plastic caps.
Vertical separators for each radius.
Chloride free plastic separators between each row, every 2 meters.
Each bundle is covered with plastic.
Customers can provide a packing drawing.
Packing lists, covered with plastic, are placed on each wooden box
for easy identification of order details – including exact list of
radii and lengths inside.
