排烟管道展开步骤基本上可以分为熟悉图形，形体分析，求直线的实长或平面的实形，确定展开方法和画展开图这几个部分。在进行展开下料前，首先要熟悉施工图纸，这是一项准备工作，主要是对将要展开的关键和部件有所了解，如管道在图纸上的尺寸大小、制作材料等。而对于比较复杂的管件，则需要对施工图纸进行反复阅读和分析，针对有关问题要及时提出和解决。由于通风管件及其部件在图纸上都是几何图形，而对形体进行分析的主要目的就是将复杂的几何图形简单化。通过分析，以便找到恰当的展开方法。

The expansion steps of smoke exhaust pipe can be basically divided into familiar graphics, shape analysis, finding the real length of a straight line or the real shape of a plane, determining the expansion method and drawing the expansion drawing. Before unfolding and blanking, first of all, be familiar with the construction drawings, which is a preparatory work, mainly to understand the key and components to be unfolded, such as the size of the pipeline on the drawings, manufacturing materials, etc. For the more complex pipe fittings, it is necessary to read and analyze the construction drawings repeatedly, and put forward and solve the relevant problems in time.
