Umbhobho wensimbi unecandelo elingenanto, kwaye ubude bayo bukhulu kakhulu kunobubanzi okanye umjikelezo wentsimbi.Ngokwemilo yecandelo, ihlukaniswe kwiibhobho zetsimbi ezijikelezayo, zesikwere, ezixande kunye nezikhethekileyo;Ngokwezinto eziphathekayo, yahlulwe kumbhobho wensimbi ye-carbon structural, i-alloy low structural steel pipe, i-alloy iron pipe kunye ne-composite steel pipe;Ikwahlulwe kwimibhobho yentsimbi yokuhambisa imibhobho, izakhiwo zobunjineli, izixhobo ezishushu, ishishini lepetrochemical, ukuveliswa koomatshini, ukugrumba i-geological, izixhobo zoxinzelelo oluphezulu, njl.Ngokwenkqubo yokuvelisa, yahlulwe ibe yipayipi yentsimbi engenamthungo kunye nombhobho wentsimbi odityanisiweyo.Umbhobho wentsimbi ongenamthungo wahlulwe waba kuqengqeleka ashushu kunye nokuqengqeleka okubandayo (umzobo), kwaye umbhobho wentsimbi odityanisiweyo wahlulwe waba ngumbhobho wentsimbi odityanisiweyo othe tye kunye nomthungo wentsimbi ojijekileyo.
I-China ngumvelisi oyintloko wemibhobho yentsimbi emhlabeni.Ngo-2020, imveliso yesizwe ibizizigidi ezingama-89.5427 zeetoni, kunye nokunyuka konyaka-nyaka nge-3.73%, kubalelwa malunga ne-60% yemveliso yehlabathi.Ngexesha elifanayo, umjikelo wokubonelela kwishishini lombhobho wensimbi uhambelana ngokusondeleyo nenzuzo yeziseko zophuhliso, ulawulo lukamasipala kunye noshishino lokuvelisa.Ngoko ke, phantsi kokuphunyezwa kwe "isicwangciso se-14 seminyaka emihlanu" kunye nomgaqo-nkqubo omtsha weziseko ezingundoqo, ukunikezelwa kweshishini lombhobho wensimbi yaseChina kuya kuqhubeka nokugcina ukukhula.
