Bending
Process Part 2
Maximum pipe bend angle is normally
90 degrees. This is a commonly used process where high
levels of cross section ovality are acceptable such as
furniture tubing, conduit and handrails.
During roll pipe bending, a series of spool-like rollers
apply pressure to the pipe as it passes through them.
Operators change the location of the rollers to produce
pipe of the desired radius. This process is ideal for
forming helical pipe coils for heat transfer applications
as well as long sweeping sections such as those used in
steel construction-curved trusses and roof components
for structures requiring large open spaces. It deforms
the pipe cross section very little for such sweeping sections.
