11. TECHNICAL STANDARDS FOR INSTALLATION

11.1. Preamble

All theoretical calculations and considerations contained in this manual are valid at an ambient temperature of installation between 15 and 25°C.

Range due to thermal expansion

CAUTION In the event that the installation takes place at temperatures outside the range indicated above, necessary corrections will have to be made.

11.2. Clamping of the pipe

The minimum distance from the fitting of the bracket must be 100/150 mm to allow for the slipping of the pipe due to thermal expansion. When the piping is longer than 30 metres, you must insert the appropriate means of compensation for expansion (expansion coefficient of the aluminum K = 0.000023). When planning the system, you should consider the minimum clearances necessary to ensure the proper expansion of the pipe.

11.3. Calculation of bending points

In order to allow the proper operation of the system, absorption points must be sized and prepared on long sections to take care of expan- sion caused by temperature changes.

KEYWORDS A-B * = UNIT (mm)

* The B unit is not binding for the operation

L-L1-L2 = LENGTHS (mt) DL = EXPANSION (mm) DT = TEMPERATURE RANGE (°C) M = MOBILE BRACKET F = FIXED BRACKET

EXEMPLES:

L1 = 40 mt DT = 50°C DL = DT x 0.02 x L = 50 x 0.02 x 40 = 40 mm L2 = 40 mt

DL = DT x 0.02 x L A = DL x 23 B = 0.7 x A

A = DL x 23 = 40 x 23 = 920 mm B = 0.7 x A = 0.7 x 920 = 640 mm
