Custom made bends - Bilfinger

Piping Systems
Bilfinger Piping Technologies GmbH
Cold bending
The Bilfinger Piping Technologies manufacturing
portfolio is supplemented with a
CNC cold bending machine which is suitable
for bends between 10 and 168.3 mm pipe
outside diameter and a maximum bending
radius of 820 mm. We guarantee our cold
bends with R/D ratios larger than 3.0 wall
thickness reduction smaller than 20 % and
ovalities better than the VGB guidelines.
The next table indicates the options of
standard cold bending.
