管道壁厚等级对照表
管道是用管子、管子联接件和阀门等联接成的用于输送气体、液体或带固体颗粒的流体的装置。
通常，流体经鼓风机、压缩机、泵和锅炉等增压后，从管道的高压处流向低压处，也可利用流体自身的压力或重力输送。
管道的用途很广泛，主要用在给水、排水、供热、供煤气、长距离输送石油和天然气、农业灌溉、水力工程和各种工业装置中。
1、以钢管壁厚尺寸表示，即“管外径×壁厚”，如φ89X4
钢管壁厚不可能各处相同，在其横截面及纵向管体上客观存在壁厚不等现象，即壁厚不均。
为了控制这种不均匀性，在有的钢管标准中规定了壁厚不均的允许指标，一般规定不超过壁厚公差的80%。
2、以管子表号Sch表示：
对于碳钢管壁厚有：Sch10、zhi20、30、40、60、80、100、120、140等10个等级（若数字后面加S，表示不锈钢管）。
对于不锈钢壁厚系列有：5S、10S、40S、80S四个等级。
3、以管子重量表示，如STD(标准重量)，XS(加厚管)，XXS(特厚管)。

管道壁厚等级对照表
钢管壁厚标准有三种衡量方式：
1、以钢管壁厚尺寸表示，即“管外径×壁厚”，如φ89X4
钢管壁厚不可能各处相同，在其横截面及纵向管体上客观存在壁厚不等现象，即壁厚不均。
为了控制这种不均匀性，在有的钢管标准中规定了壁厚不均的允许指标，一般规定不超过壁厚公差的80%。
2、以管子表号baiSch表示：
对于碳钢管du壁厚有：Sch10、zhi20、30、40、60、80、100、120、140等10个等级（若数字后面加S，表示不锈钢管）。
对于不锈钢壁厚系列有：5S、10S、40S、80S四个等级。
3、以管子重量表示，如STD(标准重量)，XS(加厚管)，XXS(特厚管)。
扩展资料：
尺寸
1、公称尺寸：是标准中规定的名义尺寸，是用户和生产企业希望得到的理想尺寸，也是合同中注明的订货尺寸。
2、实际尺寸：是生产过程中所得到的实际尺寸，该尺寸往往大于或小于公称尺寸。
这种大于或小于公称尺寸的现象称为偏差。
3、米重：每米重量=0.02466*壁厚*（外径-壁厚）
偏差和公差
1、偏差：在生产过程中，由于实际尺寸难于达到公称尺寸要求，即往往大于或小于公称尺寸，所以标准中规定了实际尺寸与公称尺寸之间允许有一差值。
差值
为正值的叫正偏差，差值为负值的叫负偏差。
2、公差：标准中规定的正、负偏差值绝对值之和叫做公差，亦叫"公差带"。
偏差是有方向性的，即以"正"或"负"表示；公差是没有方向性的，因此，把偏差值称为"正公差"或"负公差"的叫法是错误的。

19壁厚等级：Sch5s、Sch10s、Sch40s、S2）以钢管壁厚尺寸表示中国、ISO、日本部分钢管标准采用ch80s四个等级；表示英制管壁厚系列：Sch。
20——-—全称:Schedule 20Sch.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。
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≤250mm的管子，Sch40相当于STD,DN<200mm的管子，Sch80相当于XS。
