What do the model numbers of outdoor fire hydrants, such as SS150/80-1.6, mean?
Thread Content
The model of the outdoor fire hydrant is SS150/80-1.6. May I ask: what do each of these letters and numbers mean? What does the number 80 represent? Could it represent the specifications of the fire hose? But after checking, there are no fire hoses with an 80-millimeter caliber?
: SS stands for above-ground fire hydrant; 150/80 indicates that the inlet diameter is 150 mm and the outlet diameters are 80 mm and 150 mm; 1.6 represents a nominal pressure of 1.6 MPa. Fire hydrants of this specification are not commonly used; generally, they have a diameter of 65 mm.
Question: Is a 80-mm fire hose not commonly used? Is this specification still not available?
The diameter of mobile fire hoses is generally 80 mm. In addition, ordinary fire hydrants usually have two outlets, one with a diameter of 80 mm and the other of 65 mm
Yes, the diameters of fire hydrant outlets, fire hose connections, and fire nozzle connections must be standardized. There are three types: 80, 65, and 50.
SS150/80-1.6 —— Outdoor above-ground fire hydrant, with outlet sizes of 150 and 80, nominal pressure of 1.6 MPa :)
We have this type of fire hydrant outdoors, and we need a adapter from DN80 to DN65
