中国金属学会铸铁管委员会与中国城镇供水协会于1998年7月8日在京召开座谈会,就有关铸铁管的发展方向等问题进行了研讨。中国水协秘书长肖绍雍、中国金属学会铸铁管委员会秘书长李长和、北京市政工程研究院、首钢、鞍钢、北京市自来水公司、四川简阳铸管厂等部分领导同志参加了此次会议。会议就铸铁管今后在自采水行业的发展方向问题进行了讨论。中国水协秘书长肖绍雍重申:在供水行业管材的选用上仍然按《城市供水行业2000年技术进步发展规划》中指出的那样:“选择管材的基本原则是:能承受要求的内压和外荷载;使用性能可靠,维修工作量少,施工方便;使用年限长;内壁光滑,输水能力能基本保持不变;造价低。考虑上述因素,从我国国情出发,一般考虑如下:(1)≤200mm 的水管只要使用柔性接口,目前连续浇铸铸铁管仍能使用。但基本趋势是用塑料管。(2)300～1000mm 水管球墨铸铁管是理想的管材,铸态球墨铸铁管已能基本避免爆管等因素,价格较便宜,是当前可选用的管材。”国家科委蓝皮书中指出要优先发展球墨铸铁管。
The China Metal Society’s Cast Iron Pipe Committee and China Town Water Supply Association held a symposium in Beijing on July 8, 1998 to discuss the development direction of cast iron pipes. The leaders of the Chinese Water Association, Xiao Shaojun, the Secretary-General of the China Iron Council, Li Changhe, the Beijing Municipal Engineering Research Institute, Shougang, Angang, Beijing Water Supply Company, and Sichuan Jianyang Casting Plant attended the meeting. . The meeting discussed the development direction of the cast iron pipe in the self-produced water industry in the future. The Chinese Water Association secretary-general Xiao Shaoyu reiterated that the selection of pipes in the water supply industry is still based on the “Technical progress and development plan of the 2000 urban water supply industry”: “The basic principle for selecting pipes is: Can withstand the required internal pressure And external loads, reliable performance, low maintenance workload, convenient construction, long service life, smooth internal walls, basically the same water supply capacity, and low cost, taking into consideration the above factors, starting from China’s national conditions, the general considerations are as follows: ) Pipes with ≤ 200mm can be used as long as the flexible interface is used, but the basic trend is to use plastic pipes.(2) 300～1000mm ductile iron pipe is the ideal pipe, and the as-cast ductile iron pipe can basically Avoid pipe explosion and other factors, the price is cheaper, is the current choice of pipe. " The National Science Council Blue Book pointed out that priority should be given to the development of ductile iron pipes.
