JI3G3452:1997Carbon steel pipes for ordinary pipingIntroduction This Standard comes to be conformed with "unifying perfarmance testmetbiod of the equipments for water supply service"established following the revision of"standard of the strocture and material of water supply facility hased on Water WorksLow".However,since steel plpes of this Standard are not suitable for water supply servieebased on the Water Works Law,water supply service is eliminated from the appllcable rangeby this revision.1 Scope This Japanese Industrial Standard specifies the carbon ateel pipes (hereafterreferred to as the "pipes")used for the pipings for conveying steam,water (excepting publicwater spply service),oil,gas,air,etc.at comparatively low working pressures.2 Nermative references Tbe standsrds shown in Attsched Table 1 contain provisiocswhich,through refereace in this Standard.constitute provisions of this Standard.The mostrecent editions of the standards indicated below shall be applied.3 Grade and designation The pipe shall be classified into one grade and its letter symbolshatl be as given in Table 1.and subdivided into black pipes and galvanized anes accordingto nonexistenee or existence of ginc-coated layers.Table 1 Letter symbol of gradeLemer symbol of cradeDivisionRemarksac立piePipe without zinc coatingSGPCalvasized pipeBlhc线pipe with zinc co四tir尾Remarks:Where it is necessary to identify the galvanized pipeby the letter symbol on the drawing and other docu-ments,"-ZN"shall be suffixed to the letter aymbolof the grade.This notation,however,shall not beapplied to the produet itself.4 Chemieal composition The pipe shall be subjected to the test of 11.1 and the resultingLadle analysis values shall be as given in Table 2.Table 2 Chemical compositionUnit:%Lemer symbol of geadeSOP0040ma%.0.040层e元s Mechanical properties5.1 Temstle strength and elongation The black pipe shall be subjected to the test of 11.3and the resulting tensile strengtb and eloogation shall be as given in Table 3.一153一
