- Abstract:
- The design, installation, inspection and testing of fire water supply system in a foreign founded auto parts factory was introduced in this paper based on the requirements of both Chinese codes and National Fire Protection Association (NFPA) standards. The differences on fire water supply system between the Chinese codes and NFPA standards were compared and studied from the following aspects: construction of fire pump house, selection of fire pumps, the installation of fittings on the suction & outlet section and the control of fire pumps. The selection and position of pressure gauges, reducing pipe, check valve and control valves on suction and outlet side of fire pump were emphasized. The design and installation of main relief valve and flow meter in NFPA 20 were adopted by comparison. The unique design and installation of circulation relief valve and pressure sensing lines in NFPA 20 were supplemented. The purpose of all the recommendations was to improve the reliability of fire water supply system reasonably.
