管道相对标高的画法：

1、在无法标注垂直尺寸的图样中，应标注标高。标高应以m为单位，并应精确到cm或mm。

2、标高符号应以直角等腰三角形表示。当面标准层较多时，可只标注与本层楼（地）板面的相对标高。

3、水、汽管道所标高未予说明时，应表示为管中心标高。

4、水、汽管道标注管道外底或顶标高时，应在数字前加“底”或“顶”字样。

5、矩形风管所注标高应表示管底标高；圆形风管所注标高应表示管中心标高。当不采用此方法标注时，应进行说明。

6、平面图中无坡度要求的管道标高可标注在管道截面尺寸后的括号内。必要时，应在标高数字前加“底”或“顶”的字样。

1、低压流体输送用焊接管道规格应标注公称通径或压力。公称通径的标记应由字母“DN”后跟一个以亳米表示的数值组成；公称压力的代号应为“PN”。

2、输送流体用无缝钢管、螺旋缝或直缝焊接钢管、铜管、不锈钢管，当需要注明外径和壁厚时，应用“D（或Φ）外径×壁厚”表示。在不致引起误解时，也可采用公称通径表示。

3、塑料管外径应用“de”表示。

4、圆形风管的截面定型尺寸应以直径“Φ”表示，单位应为mm.

5、矩形风管（风道）的截面定型尺寸应以“A×B”表示。“A”应为该视图投影面的边长尺寸，“B”应为另一边尺雨。A、B单位均应为mm。

6、水平管道的规格宜标注在管道的上方；竖向管道的规格宜标注在管道的左侧。双线表示的管道，其规格可标注在管道轮廓线内。
