1800 Mm Unbraided Flexible Sprinkler Hose

Safe On 1800 Mm Unbraided Flexible Sprinkler Hose are composed of the same components: a sealing assembly or ‘plug’ that prevents water from escaping, a heat-sensitive element that allows water to flow at a given temperature, a deflector that distributes water effectively, and a frame. Fire sprinkler heads feature heat-sensitive parts – either a glass bulb or a fusible link – that cause them to activate at a specific temperature. When a sprinkler head has a glass bulb, that bulb typically contains a glycerin-based liquid. Once the air around the sprinkler reaches a certain temperature – often 155F (68C) – the liquid expands which causes the glass to break. The water held back by the bulb then escapes and flows toward the deflector, which disperses it throughout the room. Fusible link fire sprinklers replace that bulb with metal components secured to the sprinkler by a heat-sensitive alloy. Rising temperatures cause the alloy to melt, allowing the metal elements to fall from the sprinkler head and activate the sprinkler. Our fire sprinklers is available in 1/2″ (12.7 mm) size. A 1/2″ model is the most common size for office buildings, hotels, and schools.
