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。

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。
