- Abstract:
- Selection standards of PSP chemical pipe nominal pressure grade are inconsistent in fire-fighting water supply systems. Therefore, a general method for determining the PSP chemical pipe pressure grade in a temporary high-pressure fire-fighting water supply system was proposed through investigating the differences in test pressure standard name and test duration among specifications, pipeline standards and regulations. The PSP chemical pipe nominal pressure grade determined in Technical Specification for Buried Plastic Pipeline of Water Supply Engineering(CJJ 101-2016) was greater than that in Technical Code for Fire Protection Water Supply and Hydrant Systems(GB 50974-2014). Therefore, the PSP chemical pipe pressure grade determined in Technical Specification for Buried Plastic Pipeline of Water Supply Engineering(CJJ 101-2016) should be selected in order to meet the engineering needs.
