镀锌钢管广泛地被应用于水、煤气及油的输送管道,电缆管道和暖气管道等.它是工业和公共建筑事业,水利工程和化工设备等所需要的经济钢材之一。故辨识镀锌管的质量好坏,对工业建设、公用与民用建筑工程等,都有一定的现实意义.镀锌管的质量,主要是由锌层量、硫酸铜浸蚀试验,水压试验,冷弯试验和尺寸精度来决定的.锌层量一般每平方米
Galvanized steel pipe is widely used in water, gas and oil pipelines, cable ducts and heating pipes, etc. It is one of the economic steel required for industrial and public construction, water conservancy projects and chemical equipment. Therefore, the quality of galvanized pipe is good or bad, which has some practical significance for industrial construction, public and civil engineering, etc. The quality of galvanized pipe is mainly composed of zinc layer, copper sulfate etching test, hydrostatic test , Cold bend test and dimensional accuracy to determine the amount of zinc layer per square meter
