● The pipes are glued to the pipe connection
● Material: Typically PVC or ABS depending on
the ambient conditions
3.4.2 Branches and bends
90° bend
● For changes of direction in the pipe system
● 90° bend angle
● Flange for holding the pipe at both ends
● The pipes are glued to the bend
● Recommendation: Use a bend with the largest
possible radius, e.g.,70mm
● Material: Typically PVC or ABS depending on
the ambient conditions
