- Abstract:
- The fire water supply of a petrochemical wharf upgrading project takes advantage of the fire pumping station and foam station behind. According to the review of the new fire protection specification, the fire water volume shall be increased, resulting in the increase of fire pressure, so it is necessary to transform the fire pumping station and pipe network. However, it is difficult to reconstruct the current fire pumping station and pipe network. The strategy of low pressure usage of high pressure water and foam monitors was thus proposed to maximize the utilization of the existing facilities. The working pressure of the water and foam monitors were reduced by transforming the flow rate and working pressure of existing water and foam monitors from 80 L/s and 1.0 MPa into 98 L/s and 0.8 MPa. Finally, the design pressure of the whole pipe network was reduced, and the problems of difficult reconstruction of fire pumping station and foam station were effectively solved, which not only saved the project cost, but also shortened the construction period. At present, the project has been put into operation.
