11.10. Bevel with hose
As an alternative to "standard" bevels it is possible to use hoses by following the instructions below.
DL = DT x 0,02 x L B = (2xR) + DL1 + DL2 Y
KEYWORDS L1-L2 = LENGTHS (mt)
DL1-DL2 = EXPANSIONS (mm) DT = TEMPERATURE RANGE (°C) M = BRACKET R = RADIUS A-B = UNITS (mm)

CAUTION For flexible hoses, refer to the manufacturer's data.
11.11. Curve with hose
It is possible with the use of the hose to manage the change of direction and simultaneously compensate for the thermal expansion.
L min = 1000 mm
KEYWORDS L1-L2 = LENGTHS (mt) DL1-DL2 = EXPANSION (mm) M = BRACKET R = RADIUS L = FLEXIBLE DEVELOPEMENT (mm)
Avoid curves which are too "closed" and too "stretched".
