Segmented chemically resistant bends are normally available with angles as follows: 30o, 45o, 60o i 90o, with connection couplers at both ends. It is recommended to use segmented bends in systems of high transport velocity / pressure and with side dimension A > 400 mm. The bend retains equal cross-section along its entire length (during the transport of air its speed does not change) and the standard radius equals R = A.
