SEI-SCH-壁厚对应表

管道壁厚sch对照表一、引言管道壁厚(Schedule，缩写为SCH)是指管道在设计和制造过程中所采用的标准化厚度。

在工程领域中，使用统一的壁厚标准可以确保管道的质量和安全性。

本文将介绍常见的管道壁厚SCH对照表，以帮助读者更好地了解和选择适合的管道壁厚。

二、下面是常见的管道壁厚SCH对照表：管道尺寸（英寸） | SCH5S | SCH10S | SCH40S | SCH80S | SCH160 | SCHXS | SCHXXS-------------------|----------|-----------|-----------|----------|------------|---------|---------1/4 | 0.03 | 0.049 | 0.088 | 0.119 | 0.19 | 0.307 | 0.4143/8 | 0.049 | 0.049 | 0.091 | 0.126 | 0.23 | 0.337 | 0.4931/2 | 0.049 | 0.065 | 0.109 | 0.147 | 0.295 | 0.408 | 0.6223/4 | 0.049 | 0.065 | 0.113 | 0.154 | 0.308 | 0.493 | 0.3081 | 0.049 | 0.065 | 0.133 | 0.179 | 0.358 | 0.581 | 0.7141 1/4 | 0.049 | 0.065 | 0.14 | 0.191 | 0.382 | 0.61 | 0.8571 1/2 | 0.049 | 0.065 | 0.145 | 0.2 | 0.4 | 0.631 | 1.012 | 0.065 | 0.065 | 0.154 | 0.218 | 0.436 | 0.682 | 1.222 1/2 | 0.083 | 0.083 | 0.203 | 0.276 | 0.552 | 0.815 | 1.943 | 0.083 | 0.083 | 0.216 | 0.3 | 0.6 | 0.908 | 2.53 1/2 | 0.083 | 0.083 | 0.226 | 0.318 | 0.636 | 0.965 | 2.974 | 0.083 | 0.083 | 0.237 | 0.337 | 0.674 | 1.02 | 3.385 | 0.109 | 0.109 | 0.258 | 0.375 | 0.75 | 1.16 | 4.326 | 0.109 | 0.109 | 0.28 | 0.432 | 0.864 | 1.34 | 5.49三、结论通过以上的管道壁厚SCH对照表，我们可以清晰地了解到不同尺寸管道的标准壁厚。
