Ubungakanani bombhobho bucaciswe ngamanani amabini angena-dimensional:
Ubungakanani bombhobho oqhelekileyo (NPS) ngokwedayamitha esekwe kwii-intshi.
Inombolo yeShedyuli (SCH ukucacisa ubukhulu bodonga loMbhobho.
Bobabini ubungakanani kunye neshedyuli iyafuneka ukucacisa ngokuchanekileyo isiqwenga esithile sombhobho.
Ubungakanani bombhobho obizwa ngokuba yiNPS (NPS) yiSeti yangoku yaseMntla Melika yobungakanani obuqhelekileyo bemibhobho esetyenziselwa uxinzelelo oluphezulu kunye nobushushu obuphantsi.Ingxoxo eyongezelelweyo yoku ilapha.
Ubungakanani bombhobho we-Iron (IPS) ibingumgangatho wangaphambili kune-NPS yokumisela ubungakanani.Ubungakanani bebumalunga nedayamitha yangaphakathi yombhobho ngee-intshi.Umbhobho ngamnye unobunzima obunye, ogama lingu (STD) uMgangatho okanye (STD.WT.) Ubunzima obuMgangatho.Kwakukho ungqimba lwamadonga olu-3 kuphela ngelo xesha.NgoMatshi ka-1927, i-American Standards Association yenza inkqubo etyunjwe ubukhulu bodonga ngokusekelwe kumanyathelo amancinci phakathi kobukhulu kwaye yazisa ubungakanani bombhobho obizwa ngokuba yi-Nominal Pipe Size eyathatha indawo yeSize ye-Iron Pipe.
Inombolo yeShedyuli yobunzima bodonga ukusuka kwi-SCH 5, 5S, 10, 10S, 20, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160, STD, XS (Eyongezelelweyo Eyongezelelweyo) KUNYE neXXS (Double Strong) Yomelele).
ImiGaqo yoMdla yePipe kunye neTubing
BPE – Black Plain End Pipe
I-BTC-I-Black Threaded & Coupled
I-GPE – Isiphelo esiNcinci seGalvanized
I-GTC-Imisonto eGalvanized & Idityanisiwe
I-TOE-I-Treaded One End
Imibhobho yoKwaleka kunye nokuGqiba:
I-Galvanized - Igqunywe nge-zinc ekhuselayo yokukhusela kwintsimbi yokukhusela izinto eziphathekayo.Inkqubo inokutshisa-i-dip-galvanizing apho izinto zifakwe kwi-zinc etyhidiweyo okanye i-Electro-Galvanized apho i-sheet yensimbi eyenziwe kuyo umbhobho yayifakwe i-galvanized ngexesha lemveliso nge-electro-chemical reaction.
Ukungagqunywanga – uMbhobho ongagqunywanga
I-Black Coated - Igqunywe nge-iron-oxide enombala omnyama
I-Red Primed -I-Red Oxide Primed esetyenziswa njengesambatho sesiseko sesinyithi, inika umphezulu wentsimbi kunye nentsimbi umaleko wokhuselo.
