济南镀锌管实际上就是将钢管镀锌,为的是提高钢管的耐腐蚀性。镀锌管分为电镀锌管和热镀锌管。首先根据现场进度情况在适当的时候进入安装。预先将支架固定好,根据实际尺寸,绘好草图,进行预制管道,尽可能减少在管道上上管件,焊死口。管子预先调直,安装中断时应封闭敞口,设计要求加套管的在安装过程中加好套管,根据设计和设备的要求,预留好接口,上好堵,准备下一步工序的试压工作。

In fact, the galvanized pipe in Ji'nan is to galvanize the steel pipe to improve the corrosion resistance of the steel pipe. Galvanized pipes are divided into galvanized and hot-dip galvanized pipes. First of all, according to the site progress in the appropriate time to enter the installation. Fix the bracket well in advance, draw a sketch according to the actual size, make the prefabricated pipe, reduce the pipe fittings on the pipe as far as possible, and weld the die. When pipes are pre adjusted, they should be closed when the installation is interrupted. The casing is designed and installed. During the installation process, bushing is set up. According to the requirements of design and equipment, the interface is reserved, and the upper part is blocked up, so as to prepare for the pressure test of the next step.
