钢管壁厚表示方法

钢管壁厚表示方法有管子表号、钢管壁厚尺寸和管子重量三种方法

1）是以管子表号"Sch"表示壁厚。

管子表号是管子设计压力与设计温度下材料许用应力的比值乘以1000,并经圆整后的

数值。

即: Sch＝P/[σ]t×1000

ANSI B36.10壁厚等级：Sch10、Sch20、Sch30、Sch40、Sch60、Sch80、Sch100、

Sch120、Sch140、Sch160十个等级;

ANSI B36.19壁厚等级：Sch5s、Sch10s、Sch40s、Sch80s四个等级;

2）以钢管壁厚尺寸表示 中国、ISO、日本部分钢管标准采用

3）是以管子重量表示管壁厚度,它将管子壁厚分为三种：

a.标准重量管,以STD表示

b.加厚管， 以XS 表示

c.特厚管， 以XXS表示。

对于DN≤250mn的管子，Sch40相当于STD，DN<200mm的管子,Sch80相当于

XS。

8"SCH40":是DN200,外径为8.625in=219 mm 壁厚为0.322in=8.1788mm

没有8“SCH40 12” 8"SCH40 14"的规格!
