Standard round bends are available in 90, 60, 45, 30 and 15° angles. The turning radius R in a standard bend is equal to its diameter D. Note For D 100-315 A=40 mm, for D 355-800 A=60 mm, for D 900 and above A=100 mm. Bends are manufactured: 30-15° - from 2 segments, 60-45° - from 3 segments, 90° - from 4 segments. It is possible to produce bends on special order of any design.
