Flexible metal pipes of our catalogue
Flexible metal pipes Gnali Bocia: the reference standard for the welding of fittings and the protective sheath
For a safe connection of user equipment both to the water supply and to the methane gas, we may use a wide range of flexible metal pipes available in the GNALI BOCIA catalogue. The advantage of their use is the fact of having a continuous wall that ensures a better connection security.
Construction technology, in fact, stipulates that in the flexible metal pipes the fittings at the ends should be welded directly to the pipe; the precision is provided by the TIG welding technique that makes it possible to obtain a clean junction necessitating no subsequent treatments. The construction is regulated by the EN 14800 standard which prescribes, for use with combustible gases, fixed-length flexible pipes.
The same standard also lays down that flexible metal pipes must be protected with a sheath in plastic material that helps preserve the metal from any abrasions, also because any abrasion or damage, including a partial one, will void compliance and makes its replacement compulsory.
The catalogue further includes flexible metal pipes, but in this case they cannot be used for the conveyance of gaseous fuels.
