Flexible sprinkler piping is UL Listed under product category VENF as “Flexible Sprinkler Hose with Fittings”. This category covers flexible sprinkler hose with fittings intended for use in sprinkler systems between the branch line and sprinkler when installed in accordance with safety standards. A flexible sprinkler hose assembly consists of a flexible hose, inlet fitting for connection to the branch line and an outlet fitting for connection to the sprinkler. These flexible hose fittings are intended to be installed using the anchoring devices referenced in the manufacturer’s installation instructions. To a maximum of 6 feet, flexible hose length is limited so as to minimize the potential for inadequate support and undesirable movement of a sprinkler after installation. As indicated in the individual Listings, these products may have high flexibility or limited flexibility. Products having high flexibility are intended for use in applications where frequent movement between the two ends of the hose is expected after installation. Products having limited flexibility are intended for use in applications where little or no movement between the two ends is expected after installation.
These products are intended for use in hydraulically-designed sprinkler systems. The hydraulic pressure loss associated with these devices needs to be included in the hydraulic design calculations. Pressure loss is published in equivalent length, in feet of 1-in. diameter Schedule 40 steel pipe (where the Hazen-Williams coefficient of friction is C equals 120).
The Sprinkler Flexible Hose & Fittings offered by us is used for the purpose of extinguishing the fire of different classes. The unique sprinkling action of these hose pipes ensures that large areas affected by the fire are covered at a time.
Automatic fire sprinklers are individually heat-activated and attached to a network of piping with water under pressure. When the heat of a fire raises the sprinkler temperature to its operating temperature (usually 186°F - 86°C), a solder link will melt or a liquid-filled glass bulb will shatter to open that sprinkler, releasing water and sounding an alarm. By acting automatically at the origin of a fire, sprinklers prevent a fire from going to a dangerous size.
