Umbhobho wentsimbi ungahlulwahlulwa ube ziindidi ezimbini ngokwendlela yokuvelisa: umbhobho wentsimbi ongenamthungo kunye nombhobho wentsimbi engenamthungo, umbhobho wentsimbi engenamthungo ubizwa ngokuba ngumbhobho wentsimbi othe tye.

1. Umbhobho wentsimbi engenamthungo unokwahlulwa ube: umbhobho ongenamthungo ojijekileyo oshushu, umbhobho otsalwa ngokubandayo, umbhobho wentsimbi echanekileyo, umbhobho wokwandisa oshushu, umbhobho ojikelezayo obandayo kunye nombhobho wokukhupha, njl. Iityhubhu zentsimbi ezingenamthungo zenziwe ngentsimbi yekhabhoni esemgangathweni ophezulu okanye intsimbi ye-alloy, enokujijelwa ngokushushu okanye ngokubandayo.

2. Umbhobho wentsimbi yokuwelda wahlulwe waba ngumbhobho wokuwelda wesithando somlilo, umbhobho wokuwelda ngombane (ukuwelda kokumelana) kunye nombhobho wokuwelda we-arc ozenzekelayo ngenxa yesimo sawo esahlukileyo sokuwelda wahlulwe waba ngumbhobho wokuwelda we-seam othe tye kunye nombhobho wokuwelda ojikelezayo iintlobo ezimbini, ngenxa yesimo sawo sokugqibela wahlulwe waba ngumbhobho wokuwelda ojikelezayo kunye nombhobho wokuwelda onemilo ekhethekileyo (isikwere, isicaba, njl.njl.). Umbhobho wentsimbi ngokwezinto zetyhubhu (umz. intsimbi) unokwahlulwa ube: ityhubhu yekhabhoni kunye netyhubhu ye-alloy, ityhubhu yentsimbi engagqwali, njl. Umbhobho wekhabhoni unokwahlulwa ube ngumbhobho wentsimbi yekhabhoni oqhelekileyo kunye nombhobho wesakhiwo sekhabhoni osemgangathweni ophezulu. Umbhobho we-alloy unokwahlulwa ube:umbhobho we-alloy ophantsi, umbhobho wesakhiwo se-alloy,umbhobho we-alloy ephezulu, umbhobho onamandla aphezulu. Ityhubhu yokuthwala, ityhubhu engatyiwayo enganyangekiyo kubushushu nakwi-asidi, ityhubhu ye-alloy echanekileyo (efana ne-cutting alloy) kunye netyhubhu ye-alloy yobushushu obuphezulu, njl.

Ngokweempawu zokugquma

Umbhobho wentsimbi ngokweempawu zokugquma umphezulu ungahlulwahlulwa ube: umbhobho omnyama (ongagqunywanga) kunye nombhobho ogqunyiweyo.

Ityhubhu yokugquma inepayipi ye-galvanized, ipayipi ye-aluminium plating, ipayipi ye-chrome plating, ipayipi ye-aluminizing kunye nolunye umaleko we-alloy yombhobho wentsimbi.

Ityhubhu yokugquma inetyhubhu yokugquma yangaphandle, ityhubhu yokugquma yangaphakathi, ityhubhu yokugquma yangaphakathi neyangaphandle. Iingubo ezisetyenziswa rhoqo yiplastiki, i-epoxy resin, i-coal tar epoxy resin kunye nezinye izinto zokugquma ezichasene nokugqwala zohlobo lweglasi.

Uhlulo ngokwendlela olusetyenziswa ngayo

Inyathelo 1 Umbhobho wokufaka imibhobho. Ezifana: amanzi, umbhobho wegesi, umbhobho womphunga onombhobho ongenamthungo,umbhobho wokuhambisa ioyile, umbhobho weoyile kunye negesi. Itephu yamanzi okunkcenkceshela ezolimo enepayipi kunye nombhobho wokunkcenkceshela we-sprinkler.

2. Imibhobho yezixhobo zobushushu. Njengebhoyila eqhelekileyo enombhobho wamanzi abilayo,umbhobho womphunga oshushu kakhulu, umbhobho wobushushu webhoyila yelocomotive, umbhobho womsi, umbhobho womsi omncinci, umbhobho wezitena ze-arch kunye nobushushu obuphezulu kunyeityhubhu yebhoyila yoxinzelelo oluphezulu, njl. njl.

3. Umbhobho weshishini loomatshini.Njengombhobho wesakhiwo seenqwelomoya (umbhobho ojikelezayo, umbhobho we-ellipse, umbhobho we-ellipse othe tyaba), umbhobho we-half shaft yemoto, umbhobho we-axle, umbhobho wesakhiwo setrektara yemoto, umbhobho opholileyo weoyile yetrektara, umbhobho we-transformer kunye nombhobho wokuthwala, njl.

4. Umbhobho wokugrumba we-petroleum geology. Ezifana: umbhobho wokugrumba i-petroleum, iityhubhu ze-petroleum, isingxobo se-petroleum kunye nee-joints ezahlukeneyo ze-pipe, umbhobho wokugrumba we-geological (isingxobo, umbhobho wokugrumba osebenzayo, ukugrumba, ii-hoop kunye nee-pin joints, njl.njl.).

5. Umbhobho weshishini leekhemikhaliEzifana: nombhobho wokuqhekeka kwepetroliyam, umbhobho wokutshintsha ubushushu kunye nombhobho wombhobho wezixhobo zeekhemikhali, umbhobho ongenasinyi ongena-asidi, isichumiso esinombhobho woxinzelelo oluphezulu kunye nombhobho ophakathi wekhemikhali yokuthutha, njl.

6. Amanye amasebe asebenzisa imibhobho. Ezifana: umbhobho wesikhongozeli (umbhobho wegesi oxinzelelweyo kunye nombhobho wesikhongozeli jikelele), umbhobho wezixhobo njalo njalo.
