Umbhobho wentsimbi yekhabhoni, into esetyenziswa kakhulu kwicandelo lemizi-mveliso, udlala indima ebalulekileyo kumashishini afana nepetroleum, ubunjineli beekhemikhali, kunye nolwakhiwo. Imibhobho yentsimbi yekhabhoni eqhelekileyo yahlulwe kakhulu yaba ziintlobo ezimbini:umbhobho wentsimbi ongenamthungokwayeumbhobho wentsimbi odibeneyo.
Ngokwenkqubo yemveliso kunye nolwakhiwo, umbhobho wentsimbi ongenamthungo wenziwa ngokuqengqeleka okanye ukukhupha i-integral, ngaphandle kwemithungo edibeneyo. Inika amandla aphezulu kunye nokuqina, inokumelana noxinzelelo oluphezulu kunye namaqondo obushushu, kwaye ifanelekile kwizicelo ezifuna iimfuno ezingqongqo zokhuseleko lombhobho.
Kwelinye icala, umbhobho wentsimbi odibeneyo wenziwa ngeepleyiti zentsimbi ezijijekileyo nezijijekileyo, kunye ne-weld enye okanye ezingaphezulu. Nangona oku kunika imveliso esebenzayo ephezulu kunye nexabiso eliphantsi, ukusebenza kwayo phantsi koxinzelelo oluphezulu kunye neendawo ezixineneyo kungaphantsi kancinci kunombhobho ongenamthungo.
Kwimibhobho yentsimbi engenamthungo, i-Q235 kunye ne-A36 ziimpawu ezidumileyo. Umbhobho wentsimbi we-Q235 ludidi lwentsimbi yesakhiwo sekhabhoni esetyenziswa rhoqo eTshayina. Ngamandla okuvelisa angama-235 MPa, unika ukudityaniswa okuhle kunye nokuguquguquka ngexabiso elifikelelekayo. Usetyenziswa kakhulu ekwakheni inkxaso yesakhiwo, imibhobho yolwelo oluphantsi koxinzelelo, kunye nezinye izinto ezisetyenziswayo, ezifana nemibhobho yamanzi yokuhlala kunye nokwakhiwa kwesakhelo sentsimbi kwizakhiwo zefektri eziqhelekileyo.
Umbhobho wentsimbi yekhabhoni i-A36yinqanaba eliqhelekileyo lase-US. Amandla ayo okuvelisa afana ne-Q235, kodwa inika amandla okutsalwa kunye nokuqina okuphezulu. Isetyenziswa kakhulu kwimibhobho enoxinzelelo oluphantsi kwimveliso yoomatshini kunye nemveliso yeoyile, njengokucubungula iindawo ezincinci zoomatshini kunye nemibhobho yeoyile enoxinzelelo oluphantsi kwiindawo zeoyile.
Kwipayipi yentsimbi edibeneyo,Umbhobho wentsimbi odibeneyo we-Q235ikwayindlela ethandwayo. Ngenxa yexabiso layo eliphantsi kunye nokusebenza kwayo kakuhle kokuwelda, idla ngokusetyenziswa kwiiprojekthi zokuhambisa igesi yesixeko kunye nokuhambisa amanzi ngoxinzelelo oluphantsi. Kwelinye icala, umbhobho we-A36 welded usetyenziswa kakhulu kwiipayipi zoshishino ezinoxinzelelo oluphantsi ezineemfuno ezithile zamandla, njengemibhobho yokuthutha izinto ezinoxinzelelo oluphantsi kwizityalo ezincinci zeekhemikhali.
| Ubukhulu bokuthelekisa | Umbhobho wentsimbi we-Q235 | Umbhobho wentsimbi ye-A36 Carbon Steel |
| Inkqubo esemgangathweni | Umgangatho weSizwe waseTshayina (GB/T 700-2006 "Intsimbi yoLwakhiwo lweKhabhoni") | I-American Society for Testing and Materials (ASTM A36/A36M-22 "Ipleyiti yentsimbi yekhabhoni, iiMilo, kunye neeBhari zokusetyenziswa kwesakhiwo") |
| Amandla Okuvelisa (Ubuncinci) | 235 MPa (ubukhulu ≤ 16 mm) | 250 MPa (kuyo yonke indawo yobukhulu) |
| Uluhlu lwamandla okuThamba | 375-500 MPa | 400-550 MPa |
| Iimfuneko zoBulukhuni beMpembelelo | Uvavanyo lwempembelelo oluyi--40°C lufuneka kuphela kwiimabakala athile (umz., Q235D); akukho mfuneko inyanzelekileyo kwiimabakala aqhelekileyo. | Iimfuneko: -18°C uvavanyo loxinzelelo (imigangatho engaphelelanga); ukuqina kobushushu obuphantsi kungcono kancinci kuneeklasi ze-Q235 eziqhelekileyo |
| Imizekelo ephambili yokusetyenziswa | Ulwakhiwo lwezakhiwo (izakhiwo zentsimbi, izixhaso), imibhobho yamanzi/igesi enoxinzelelo oluphantsi, kunye nezixhobo zoomatshini ngokubanzi | Ukwenziwa koomatshini (izinto ezincinci neziphakathi), imibhobho ye-oyile enoxinzelelo oluphantsi, imibhobho ye-industrial fluid enoxinzelelo oluphantsi |
Ngokubanzi, imibhobho yentsimbi engenamthungo nedibeneyo nganye ineenzuzo zayo. Xa bethenga, abathengi kufuneka baqwalasele iimfuno zoxinzelelo kunye nobushushu besicelo esithile, kunye nohlahlo lwabiwo-mali lwabo, baze bakhethe uhlobo olufanelekileyo, olufana ne-Q235 okanye i-A36, ukuqinisekisa umgangatho kunye nokhuseleko lweprojekthi.
