Umbhobho wentsimbi yeCarbon, into esetyenziswa ngokubanzi esisiseko kwicandelo loshishino, idlala indima ephambili kumashishini afana nepetroleum, ubunjineli beekhemikhali kunye nolwakhiwo. Imibhobho yentsimbi yekhabhoni eqhelekileyo yahlulahlulwe yaba ziindidi ezimbini:umbhobho wentsimbi ongenamthungokwayeumbhobho wentsimbi odityanisiweyo.
Ngokumalunga nenkqubo yokuvelisa kunye nesakhiwo, umbhobho wensimbi ongenamthungo wenziwa ngokusebenzisa i-integrated rolling okanye i-extrusion, ngaphandle kwe-welded seams. Inika amandla aphezulu kunye nokuqina, inokumelana noxinzelelo oluphezulu kunye namaqondo obushushu, kwaye ifanelekile kwizicelo ezifuna iimfuno ezingqongqo zokhuseleko lombhobho.
Umbhobho wentsimbi odityanisiweyo, kwelinye icala, uveliswa ngokujiya kunye neepleyiti zentsimbi, kunye ne-welds enye okanye ngaphezulu. Ngelixa oku kubonelela ngokusebenza kakuhle kwemveliso kunye neendleko eziphantsi, ukusebenza kwayo phantsi koxinzelelo oluphezulu kunye neendawo ezingqongileyo ezigqithisileyo zingaphantsi kancinci kunombhobho ongenamthungo.
Kwipayipi yensimbi engenamthungo, i-Q235 kunye ne-A36 ngamabakala aziwayo. Umbhobho wensimbi we-Q235 yibakala eliqhelekileyo elisetyenziswa kwi-carbon structural steel e-China. Ngamandla isivuno 235 MPa, inika weldability okugqwesileyo kunye ductility ngexabiso elifikelelekayo. Isetyenziswa ngokubanzi kwisakhiwo senkxaso yesakhiwo, imibhobho yamanzi yoxinzelelo oluphantsi, kunye nezinye izicelo, njengemibhobho yokuhlala yamanzi kunye nokwakhiwa kwesakhelo sentsimbi kwizakhiwo eziqhelekileyo zefektri.
Umbhobho wentsimbi ye-A36libakala elise-US. Amandla ayo esivuno ayafana ne-Q235, kodwa inika amandla okuqina aphezulu kunye nokuqina kwempembelelo. Isetyenziswa kakhulu kwimibhobho yoxinzelelo oluphantsi kwimveliso yoomatshini kunye nokuveliswa kwe-oyile, njengokusetyenzwa kwamalungu amancinci omatshini kunye nemibhobho yeoli enoxinzelelo oluphantsi kwiindawo zeoyile.
Ngombhobho wentsimbi odityanisiweyo,Q235 umbhobho wentsimbi odityanisiweyoikwalibakala elidumileyo. Ngenxa yexabiso eliphantsi kunye nokusebenza kakuhle kwe-welding, isoloko isetyenziselwa ukuhanjiswa kwegesi yesixeko kunye neeprojekthi zokuhambisa amanzi ezinoxinzelelo oluphantsi. Umbhobho odityanisiweyo we-A36, kwelinye icala, usetyenziswa ngokuqhelekileyo kwimibhobho yoxinzelelo olusezantsi eneemfuno ezithile zamandla, njengemibhobho yokuhambisa imathiriyeli enoxinzelelo oluphantsi kwizityalo ezincinci zekhemikhali.
| Imilinganiselo yokuthelekisa | Q235 umbhobho wentsimbi | A36 Carbon Steel Pipe |
| Inkqubo esemgangathweni | iChina National Standard (GB/T 700-2006 "Carbon Structural Steel") | Umbutho waseMelika woVavanyo kunye neZixhobo (ASTM A36/A36M-22 "I-Carbon Steel Plate, iiMilo, kunye neeBhari zokuSetyenziswa kweZakhiwo") |
| Isivuno Amandla (Ubuncinci) | 235 MPa (ubukhulu ≤ 16 mm) | 250 MPa (kulo lonke uluhlu olugcweleyo) |
| Uluhlu lwamandla okuqina | 375-500 MPa | 400-550 MPa |
| IiMfuno zokuqina kwempembelelo | A-40°C uvavanyo lwempembelelo lufuneka kuphela kumabakala athile (umz., Q235D); akukho mfuneko yesinyanzelo kumabakala aqhelekileyo. | Iimfuno: -18 °C uvavanyo lwempembelelo (imigangatho eyinxenye); Ubushushu obuphantsi kokuqina bungcono kancinci kunamabanga aqhelekileyo e-Q235 |
| Iimeko zeSicelo eziPhambili | Ulwakhiwo loluntu (izakhiwo zentsimbi, izixhaso), imibhobho yoxinzelelo oluphantsi lwamanzi/yegesi, kunye neenxalenye zoomatshini ngokubanzi | Ukwenziwa koomatshini (amalungu amancinane naphakathi), indawo yeoli yoxinzelelo oluphantsi lwemibhobho, imibhobho yolwelo oluphantsi kweshishini |
Ngokubanzi, imibhobho yentsimbi engenamthungo kunye ne-welded nganye ineenzuzo zayo. Xa kuthengwa, abathengi kufuneka baqwalasele uxinzelelo kunye neemfuno zokushisa kwesicelo esithile, kunye nohlahlo lwabiwo-mali lwabo, kwaye bakhethe ibakala elifanelekileyo, njenge-Q235 okanye i-A36, ukuqinisekisa umgangatho weprojekthi kunye nokhuseleko.
