Connection using flexible non metal pipes
When the connection can be easily inspected in its full extent, there is the chance to use a flexible pipe according to the rules in force. The flexible pipe must be tightly fixed using clamps according to the rules in force.
The flexible pipe should be made ready for use in such a way that:
-nowhereitcanreachovertemperature, other than room temperature, higher than 30°C; if the flexible pipe, to reach the cock, must run behind the range, it must be installed as shown in the diagram;
-it is no longer than 1500 mm;
-it shows no throttles;
-it is not subject to traction or torsion;
-it doesn't get in touch with cutting edges or corners;
-it can be easily inspected in order to check its condition.
The control of preservation of the flexible pipe consists in checking that:
-it doesn't show cracks, cuts, marks of burnings both on the end parts and on its full extent;
-thematerialisnothardened,butshows its normal elasticity;
-the fastening clamps are not rusted;
-expiry term is not due.
If one or more abnormalities are seen, do not repair the pipe, but replace it.
