Pipe Size inotsanangurwa nenhamba mbiri dzisiri-dimensional:
Nominal Pipe Size (NPS) yedhayamita zvichienderana nemainch.
Nhamba Yekuronga (SCH kutsanangura ukobvu hwemadziro ePipe.
Zvose ukuru uye purogiramu inotarisirwa kunyatsotsanangura imwe chidimbu chepombi.
Nominal Pipe Size (NPS) ndiyo yazvino North America Seti yemasaizi akajairwa emapombi anoshandiswa kune yakakwirira uye yakaderera kumanikidza uye tembiricha.Imwezve hurukuro yeizvi iri pano.
Iron Pipe Size (IPS) yaive yekutanga chiyero kupfuura NPS kuratidza saizi.Saizi yacho yaive yakaenzana nepakati pedhayamita yepombi mumainji.Pombi imwe neimwe yaive neukobvu humwe, hwainzi (STD) Standard kana (STD.WT.) Standard Weight.Paingova nemadziro matatu chete panguva iyoyo.Muna Kurume 1927, American Standards Association yakagadzira hurongwa hwairatidza ukobvu hwemadziro zvichibva pamatanho madiki pakati pehukuru uye yakaunza Nominal Pipe Size iyo yakatsiva Iron Pipe Size.
Nhamba yehurongwa hwemadziro ukobvu kubva paSCH 5, 5S, 10, 10S, 20, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160, STD, XS (Yakawedzera Yakasimba) UYE XXS (Double Strong).
