按照电气装置安装工程施工及验收规范要求,钢管内壁应刷防腐漆。由于现场操作、工艺及客观条件的限制,要做到这一点往往比较困难。现介绍一种简便易行的操作方法。用角钢或钢管焊接成刷油操作架,可水平及倾斜搁置数层钢管,见图1。利用防腐漆在钢管内重力自流的原理,使钢管内壁涂上防腐漆。图中的细点划线是放置钢管的位置。将钢管搁在操作架最下层的A_1、B_1、C_1支架上,用透明半硬塑料管将 According to the electrical equipment installation engineering construction and acceptance requirements, the inner wall of the steel pipe shall be painted with anti-corrosion paint. Due to the limitations of on-site operations, processes, and objective conditions, it is often difficult to do this. Now introduce a simple and easy operation method. With angle steel or steel pipe welded into a brush oil operation, horizontal and inclined shelving several layers of steel, see Figure 1. The use of anti-corrosion paint in the principle of gravity gravity in the steel pipe, so that the inner wall of the steel pipe painted with anti-corrosion paint. The fine dotted line in the figure is where the steel pipe is placed. Put the steel pipe on the A_1, B_1, and C_1 brackets at the bottom of the rack and use a transparent semi-rigid plastic pipe.
