5.8 Bending<br />
Depending on the system, it may be necessary to bend the tube during installation. For this, commercially<br />
available manual, hydraulic or electric bending tools with the corresponding bending<br />
segments are used. The suitability of the bending tool is defined by the manufacturer. <strong>VSH</strong> <strong>Press</strong><br />
Sprinkler tubes for sprinkler installations are cold pliable in the sizes 22 and 28 mm.<br />
The minimum bending radius is as follows:<br />
Carbon and stainless steel tube<br />
<strong>VSH</strong> <strong>Press</strong> flexible hoses<br />
Rmin = 3,5 x d (max. 28 mm)<br />
22 mm = 70 mm<br />
28 mm = 85 mm<br />
Due to the danger of corrosion the tube must not be bent when it is warm<br />
