钢管尺寸

管道系统用钢管的外径、壁厚和内径参考尺寸。

steelpipesdimensions

概述

钢管尺寸由 ASME/ANSI B36.10（焊接和无缝锻钢）和 ASME/ANSI B36.19（不锈钢）标准化。无论表号如何，给定公称尺寸的所有管道都具有相同的外径。随着表号增加，壁厚增加，内孔减小。

使用三种传统的重量标识：

  • STD（标准）——给定尺寸的基准壁厚
  • XS（加厚）——较厚的壁，有时称为 XH（特厚）
  • XXS（双倍加厚）——最厚的壁，有时称为 XXH

关键公式

横截面积

A=π4(Do2−Di2)A = \frac{\pi}{4}\left(D_o^2 - D_i^2\right)

由壁厚计算内径

Di=Do−2tD_i = D_o - 2t

单位长度重量

W=ρsteel⋅AmetalW = \rho_{steel} \cdot A_{metal}

其中钢的密度约为 490 lb/ft³ (7850 kg/m³)。

工程要点

  • 制造公差对外径的影响很小但不为零；所列数值为 ASME/ANSI B36.10/19 的公称值。
  • 不锈钢管（B36.19）使用与碳钢相同的外径，但在某些 B36.10 中不存在的表号（如 5S、10S）下壁更薄。
  • Schedule 160 和 XXS 的壁厚显著增加，适用于高压工况。对于 1/2 in 至 6 in 的尺寸，XXS 壁厚大于 Sch 160。
  • 管道重量取决于材料密度；表格假定碳钢密度为 490 lb/ft³。其他合金应按密度比例调整。
  • 水的重量按管道满流且密度为 62.4 lb/ft³ 计算。
  • 公制换算：1 in = 25.4 mm；1 lb/ft = 1.488 kg/m。
