本标准适用于以碳钢、低合金钢制造的无缝对焊管件。包括三通(等径与异径),90°弯头(长半径和短半径),异径管(同心与偏心)和管帽四种,分公制和英制两个系列。 根据目前国内生产情况和使用情况,这四种管件的直径范围定为:等径三通、异径三通主管;90°弯头;同心异径管、偏心异径管大端;管帽的公称直径为50~600mm(2″~24″),异径三通其支管的最小公称直径为大端公称直径之半。公制管件公称压力分为PN25。40、64、100kgf/cm2(即2.5MPa,4.0MPa,6.4MPa、10MPa)四档。璧厚按材料许用应力〔σ〕=1310kgf/cm2,介质腐蚀裕度取1.5mm算出,英制管件接管标号(Schedule Number简写为Sch××)分为Sch40,Sch80、Sch160兰种。 本标准中所采用的单位:长度为mm(注明cm除外)、荚寸:压力为kgf/cm^(2)(1kgf/cm^(2)≈O.1MPa);重量为kg。 所有管件的管接口厚度见管件接管规格表,订货者如有特殊要求可另提。
