SCH是美标钢管的壁厚系列
SCH是美标钢管的壁厚系列
钢管壁厚的分级，在不同标准中所表示的方法也各不相同。但主要有三种表示方法。
1．以管子表号(Sch.)表示壁厚系列
这是1938年美国国家标准协会ANSIB36.10(焊接和无缝钢管)标准所规定的。
管子表号(Sch．)是设计压力与设计温度下材料的许用应力的比值乘以1000，并经圆整后的数值。即
Sch .=P/[ó]t×1000 （1-2-1）
式中 P—设计压力，MPa；
[ó]t—设计温度下材料的许用应力，MPa。
无缝钢管与焊接钢管的管子表号可查资料确定。
ANSI B36.10和JIS标准中的管子表号为；Schl0、20、30、40、60、80、100、120、140、160。
ANSI B36.19中的不锈钢管管子表号为：5S、10S、40S、80S。
管表号(Sch．)并不是壁厚，是壁厚系列。实际的壁厚，同一管径，在不同的管子表号中其厚度各异。不同管子表号的管壁厚度，在美国和日本是应用计算承受内压薄壁管厚度的Barlow公式计算并考虑了腐蚀裕量和螺纹深度及壁厚负偏差-12.5％之后确定的，如公式
(1-2-2)和(1-2-3)所示。 tB=D0P/2[ó]t （1-2-2）
t=[D0/2（1-0.125）×P/[ó]t]+2.54 （1-2-3）
式中 tB t——分别表示理论和计算壁厚，mm
D0——管外径，mm
P——设计压力，MPa
[ó]t——在设计温度下材料的许用压力，MPa
计算壁厚径圆整后才是实际的壁厚。
如果已知钢管的管子表号，可根据式（1-2-1）计算出该钢管所能适应的设计压力，即 P=Sch.× [ó]t/1000 （1-2-4）
例如，库存Sch40，碳素钢20无缝钢管，当设计温度为350oC时给钢管所能适应设计压力为：

钢管标号sch80表⽰什么意思？SCH20-SCH40-SCH80-SCH160 （附对照表）
表⽰英制管壁厚系列：Sch.20----全称：Schedule 20
Sch.10s--带s的系列为不锈钢专⽤，碳钢不⽤。
举个例⼦：2" sch.10s 表⽰2”接管的壁厚为2.9mm,材质为不锈钢；
2" sch.40 表⽰2”接管的壁厚为4.0mm。
顺便再说⼀下钢管壁厚的表⽰⽅法：
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×1000ANSI 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。
