Fire Protection
Container Valve
Adopt CuZn39Pb3, the working pressure is not less than 15Mpa.
The hydraulic strength test is carried out at 1.5 times the working pressure kept for 5 minutes without deformation or leakage.
The salt spray corrosion test shows that there is no obvious corrosion damage in each part of the container valve and no performance decline.
Fire extinguisher
Steel seamless cylinders that complt with the GB5099-1994 standard.
The maximum working pressure of the cylinder is 15 MPa. When subjected to a hydraulic strength test at 1.5 times the working pressure for 3 minutes, there is no leakage or significant residual deformation.
When subjected to a hydraulic strength test at 1.1 times the working pressure, the container should have no bubble leakage.
