Flexible water tubes made of stainless steel

Flexible water tubes, extendible and suitable for use with drinking water

Flexible tubes for water can certainly be found among our particularly important articles. Made of corrugated stainless steel, they connect devices to the water or heating systems. One of their uses, for example, is to connect the boiler to the domestic water and heating system.
The material used to make the flexible water tubes guarantees water drinkability, especially if the water is used for food or personal consumption. Two nuts are welded to the corrugated tube extremities using the TIG welding system because particularly clean. This guarantees repeatability and product quality.
Production is regulated by the UNI-CIG 7129 standard, which has remained valid only for flexible water tubes because extendable. Tubes for connection to lines where the fluid is gassy can no longer be extendible.
In addition to flexible tubes for water, the GNALI BOCIA catalogue also contains versions that can be used with gas that correspond to European Directive EN 14800, which came into force recently.
