Product Description

Fire protection watering flexible metal hose mainly used in fire control system as an important equipment, it’s a high quality flexible pipe in modern piping system. Fire protection watering flexible metal hose has advantages of good flexibility, anti-corrosive, anti-fatigue, anti high and low temperature, absorb shock and reduce noise, good sealing and long service life. Watering flexible metal hose’s inner pipe is spiral or annular shape thin-walled bellows, and the bellows is made from thin-walled seamless or welding stainless steel pipe. Bellows elasticity determines that flexible metal hose has good flexibility and anti-fatigue, making it easy to absorb all kinds of cyclic loading, in this way to guarantee the stability of pipeline connection.

Related regulation states that some public places must be equipped with automatic fire extinguishing system, it’s better to have sprinkler system, then our fire protection watering flexible metal hose becomes the necessary fire control equipment.

Product features of fire protection watering flexible metal hose:

  1. Whole stainless steel structure helps reduce dust and pollutant, 100% anti-corrosive, ensure erupting water in emergency circumstances;
  2. Good flexibility, efficiently reduce stress caused by pipe arrangement error, and prevent fracturing;
  3. Easy to install, fast assemble, reduce labor cost;
  4. Good low temperature resistance, shock resistance;
  5. Convenient and fast displacement when reassemble and change design;
  6. When come across earthquake, watering flexible metal hose can move between ceiling and main pipe, avoid leakage and protect sealing;
  7. Long service life.
