太原水泥制管厂是1954年的新建厂。开始只生产排水工程水泥管,随着我国经济的高速度发展,水泥管的需用量大大增加,在国家还不能生产更多铸铁管、而各地工程紧迫需要的时候,该厂接受制造上水管的(一般把给水管称上水管)任务。但在56年试制阶段由于工程技术人员的水泥制管技术知识有限,没有获得显著收效。后来在各有关单位和兄弟厂的大力配合下,经多次试制,终于“双层装灰法”解决了质量关键。经过不断钻研,又提出了“夹砂浆”三次连续装灰法”的试制方案:
Taiyuan Cement Pipe Plant was a new plant in 1954. At the beginning, it only produced drainage engineering cement pipes. With the rapid development of China’s economy, the demand for cement pipes has increased greatly. When the country is unable to produce more cast iron pipes and the projects are urgently needed, the factory accepts the manufacture of water pipes. (Generally, the water supply pipe is called the water pipe). However, in the 56-year trial production stage, due to the limited technical knowledge of engineering and technical personnel in cement pipe manufacturing, no significant results were obtained. Later, with the strong cooperation of the relevant units and sister factories, after several trial productions, the “double-layer loading method” finally resolved the key to quality. After continuous research, we also proposed a trial production scheme for “three-time continuous loading of ash with mortar”.
