镀锌薄壁钢管用于排灌输水管路,具有重量轻、坚固耐用、适应性强、操作方便等优点。它是由1毫米冷轧钢板辊压成型、高频堆焊成管,切成所需长度,经镀锌而成。此种钢管由水利部科技局下达镇江农机学院和南京轧钢厂共同研制,经过两年来的努力已研制成功,经机械、金相、水力、腐蚀等试验,各项指标均符合设计要求,并于1981年12月通过鉴定。本文主要叙述镀锌薄壁钢管的生产工艺、主要技术关键及各项性能测试。
Galvanized thin-walled steel pipe for irrigation and drainage pipelines, with light weight, durable, adaptable, easy to operate and so on. It is rolled by 1 mm cold-rolled steel forming, high-frequency surfacing into a tube, cut into the required length, made of galvanized. This kind of steel pipe is jointly developed by Zhenjiang Agricultural Machinery Institute of Ministry of Water Resources and Nanjing Steel Mill and has been successfully developed after two years of hard work. All the indexes are in accordance with the design requirements through the experiments of mechanical, metallurgical, hydraulic and corrosion. December 1981 passed the appraisal. This article mainly describes the production process of galvanized thin-walled steel pipe, the main technical key and various performance tests.
