FLEXIBLE SPRINKLER HOSE WITH
FIRE SPRINKLER
Flexible sprinkler hoses enhance work efficiency compared to conventional piping. Because it shortens work period by omitting several processes that conventional system used to work through. Flexible sprinkler hoses allow engineers, architects to work efficiency by reducing labor cost and installation time.
Fire sprinklers are used to stop flames in the event of a fire. They deliver a high-pressure amount of water to a fire and are heat-activated and part of a fire prevention and safety system. Fire sprinkler reservoir contains water or some other chemicals like carbon dioxide (CO2), argon (Ar), or high-expansion foam. They attach to other pipes that end at a pressure regulator that controls how much water comes out from the fire suppression reservoir.

DongWoo has become one of the best fire sprinkler fittings manufacturers and suppliers in Korea. DongWoo has developed its own supporting fire sprinkler fittings to hold all hoses firmly in any conditions and more importantly to install it conveniently. The sprinkler can be attached to the hose prior to the installation of the hose
Good design supporting bracket system / easy and fast
installation and re-installation
Dongwoo has developed its own supporting fittings to hold the hose firmly in any circumstances but also we didn't forget that it should be easy and convinient to install and re-install. The sprinkler can be attached to the hose prior to the installation of the hose.
When a automatic sprinkler has to be installed prior to install the flexible hose to ceiling structure, and the sprinkler is bigger than the hole of the cen ter bracket, the reducer of the hose has to be inserted from side, not from top of the center bracket. And it is essential for the bracket to be "open" to take the 'sprinkler pre assembled reducer from side as shown in the picture above
Conventional design which doesn't allow 'inserting the reducer from side' because of its closed structure of the center bracket will make the general installation and reinstallation very inefficinet.
"Round" ends of the hose for worker's safty
