10、10個等級（2）：不銹鋼管每米重量的計算公式：（若數字后面加S，表示不銹無縫鋼管）；W（kg/m）=0.02491*壁厚*（外徑壁厚）對于不銹鋼壁厚系列有：5S、10S、40S、80S四個等級(3):厚壁鋼管的計算方式：（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）=邊長*4*厚度*0.00785（3）以無縫鋼管壁厚尺寸表示，即“管外徑壁厚”，如89X4鋼管的規格有幾個因素確定：1鋼管的工程直徑，對應有兩種表示方法，公制和英制。公制管用DN來表示，像你所說的，DN50的鋼管外徑是57毫米。英制管用英寸來表示2鋼管的外徑是60.3毫米。公制管與英制管有

11、一個對應關系如下：NPS-DN1/2-153/4-201-2511/4-3211/2-402-5021/2-653-804-100當NPS4時，DN=25(NPS)兩種規格的管子可以通過法蘭進行連接。2使用壓力。使用壓力決定了壁厚得選取。選擇太薄的管子，強度不能達到使用要求，選用太厚的管子又浪費。公制管用X多少毫米來表示壁厚，英制管用SCH10、SCH20等來表示。至于多粗的管子在多大的實用壓力下選用哪種規格的壁厚，可以從管子壁厚規格表中查到，在工藝設計手冊中有。公稱通徑是管路系統中所有管路附件用數字表示的尺寸，公稱通徑是供參考用的一個方便的圓整數，與加工尺寸僅呈不嚴格的關系。公稱通徑用字母“

12、DN”后面緊跟一個數字標志。公稱通徑(nominaldiameter)，又稱平均外徑(meanoutsidediameter)。這是緣自金屬管的管璧很薄，管外徑與管內徑相差無幾，所以取管的外徑與管的內徑之平均值當作管徑稱呼。DN是公稱通徑，公稱通徑(或叫公稱直徑),就是各種管子與管路附件的通用口徑。同一公稱直徑的管子與管路附件均能相互連接，具有互換性.它不是實際意義上的管道外徑或內徑，雖然其數值跟管道內徑較為接近或相等；為了使管子、管件連接尺寸統一，采用公稱直徑（也稱公稱口徑、公稱通徑)。例如焊接鋼管按厚度可分為薄壁鋼管、普通鋼管和加厚鋼管。其公稱直徑不是外徑，也不是內徑，而是近似普通鋼管內徑

13、的一個名義尺寸。每一公稱直徑，對應一個外徑，其內徑數值隨厚度不同而不同。公稱直徑可用公制mm表示，也可用英制in表示。管路附件也用公稱直徑表示，意義同有縫管。外徑 壁厚 重量英寸 毫米. 單位 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
