10、10个等级（2）：不锈钢管每米重量的计算公式：（若数字后面加S，表示不锈无缝钢管）；W（kg/m）=0.02491*壁厚*（外径壁厚）对于不锈钢壁厚系列有：5S、10S、40S、80S四个等级(3):厚壁钢管的计算方式：（2）以管子重量表示，如STD(尺度重量)，XS(加厚管)，XXS(特厚管)W（kg/m）=边长*4*厚度*0.00785（3）以无缝钢管壁厚尺寸表示，即“管外径壁厚”，如89X4钢管的规格有几个因素确定：1钢管的工程直径，对应有两种表示方法，公制和英制。公制管用DN来表示，像你所说的，DN50的钢管外径是57毫米。英制管用英寸来表示2钢管的外径是60.3毫米。公制管与英制管有

11、一个对应关系如下：NPS-DN1/2-153/4-201-2511/4-3211/2-402-5021/2-653-804-100当NPS4时，DN=25(NPS)两种规格的管子可以通过法兰进行连接。2使用压力。使用压力决定了壁厚得选取。选择太薄的管子，强度不能达到使用要求，选用太厚的管子又浪费。公制管用X多少毫米来表示壁厚，英制管用SCH10、SCH20等来表示。至于多粗的管子在多大的实用压力下选用哪种规格的壁厚，可以从管子壁厚规格表中查到，在工艺设计手册中有。公称通径是管路系统中所有管路附件用数字表示的尺寸，公称通径是供参考用的一个方便的圆整数，与加工尺寸仅呈不严格的关系。公称通径用字母“

12、DN”后面紧跟一个数字标志。公称通径(nominaldiameter)，又称平均外径(meanoutsidediameter)。这是缘自金属管的管璧很薄，管外径与管内径相差无几，所以取管的外径与管的内径之平均值当作管径称呼。DN是公称通径，公称通径(或叫公称直径),就是各种管子与管路附件的通用口径。同一公称直径的管子与管路附件均能相互连接，具有互换性.它不是实际意义上的管道外径或内径，虽然其数值跟管道内径较为接近或相等；为了使管子、管件连接尺寸统一，采用公称直径（也称公称口径、公称通径)。例如焊接钢管按厚度可分为薄壁钢管、普通钢管和加厚钢管。其公称直径不是外径，也不是内径，而是近似普通钢管内径

13、的一个名义尺寸。每一公称直径，对应一个外径，其内径数值随厚度不同而不同。公称直径可用公制mm表示，也可用英制in表示。管路附件也用公称直径表示，意义同有缝管。外径 壁厚 重量英寸 毫米. 单位 毫米. 英寸. 公斤/米. 磅/英尺. 1/8”10.3 10S1.240.0490.280.19 1/8”10.3 STD-401.730.0680.370.25 1/8”10.3 XS-802.410.0950.480.32 1/4”13.7 10S1.650.0650.50.34 1/4”13.7 STD-402.240.0880.640.43 1/4”13.7 XS-803.020.1190.8
