为了加快人畜饮水工程建设步伐,扭转在供水工程中钢管缺乏的被动局面,1984年9月4日由陕西省水利水保厅农水处、西安冶金建筑学院及西安新秦塑料厂三方共同协商成立《在供水技术中以塑代钢》试验研究课题组,进行无毒塑管的试验研究,并列入省水利水保厅1985年重点科研项目.经过一年多的努力,课题组对新配方研制的 UPVC一2型白色塑管进行了毒理学试验、抗老化试验、液压爆破强度试验、管道水力特性试验和现场安装、考核等一系列
In order to speed up the pace of construction of drinking water projects for humans and animals and to reverse the passive situation of the lack of steel pipes in water supply projects, the three sides of Shaanxi Provincial Water Conservancy and Water Conservation Office, Xi’an Institute of Metallurgy and Xi’an Xinqin Plastic Factory jointly negotiated on September 4, 1984 “In the water supply technology to plastic substitution steel” pilot research group, non-toxic plastic pipe experimental study, and included in the provincial water conservancy conservancy key research projects in 1985. After more than a year of hard work, the research group of the new formula Developed a UPVC-2 white plastic tube toxicology test, anti-aging test, hydraulic burst strength test, pipeline hydraulic characteristics of the test and site installation, assessment and a series of
