Umbhobho wentsimbi yekhabhoni engenamthungo ubhekisa kumbhobho owenziwe ngentsimbi yekhabhoni ngaphandle kwamalungu adityanisiweyo okanye imithungo, kunye nebillet eqinileyo ikhutshelwa kwidiyizi ukuze yenze umbhobho wobume obufunwayo kunye nobukhulu.Umbhobho wentsimbi ongenamthungo weCarbon uthandwa ngenxa yokuqina kwawo okugqwesileyo, ukomelela kokuqina kunye nokumelana nomhlwa, oko kuyenza ilungele uluhlu olubanzi lwamashishini kubandakanya ioyile negesi, iimoto kunye nolwakhiwo.
Elinye lawona manqaku adumileyo ebhobho yentsimbi engenamthungo yiA106 iBanga B, eyona mgangatho we-ASTM wepayipi yentsimbi ye-carbon engenamthungo kwinkonzo yokushisa okuphezulu.Inomlinganiselo ophezulu wekhabhoni we-0.30%, okwenza kube yinto efanelekileyo kwizicelo ezifuna ukushisa okuphezulu kunye noxinzelelo.Ikwafanelekile kuxinzelelo oluphantsi kunye nezicelo zokushisa eziphantsi, kunye ne-welding kunye ne-brazing.
Elinye ibakala elidumileyo liAPI 5L iBanga B, okusemgangathweni wombhobho wensimbi ongenamthungo kunye ne-welded kwiinkqubo zokuhanjiswa kwemibhobho kwishishini leoli kunye negesi.Inomlinganiselo ophezulu wekhabhoni we-0.30%, okwenza kube yinto efanelekileyo yokusetyenziswa kuxinzelelo oluphezulu kunye neendawo zokushisa eziphezulu.
Ukongeza kwibakala, izinto zombhobho we-carbon seamless steel pipe nazo zibaluleke kakhulu.Izinto eziqhelekileyo zibandakanya i-SAE 1020, enomxholo ophantsi wekhabhoni kwaye ilungele ukugoba, i-flanging kunye nemisebenzi efanayo yokwenza, kunye ne-SAE 1045, enomxholo ophezulu wekhabhoni kwaye ilungele izicelo ezifuna ubunzima, ubunzima kunye nokuchasana nokugqoka.
Ezinye izinto zibandakanya i-ASTM A519 iBanga le-4130 kwimigca ye-hydraulic ephezulu yoxinzelelo kunye ne-oilfield tubing, kunye ne-ASTM A106 iBanga C elinomxholo ophezulu wekhabhoni we-0.35% kwizicelo ezifuna ukuxhathisa kwe-corrosion.
Ukuqukumbela, iibhobho zensimbi ezingenamthungo zekhabhoni ziyimfuneko kuluhlu olubanzi lwamashishini kunye nokukhethwa kwebakala kunye nezinto eziphathekayo kuxhomekeke kwisicelo esithile.I-A106 iBanga B kunye ne-API 5L iBanga B ngamabakala athandwayo, ngelixa izixhobo ezifana ne-SAE 1020, SAE 1045,I-ASTM A519 iBakala 4130, kunye ne-ASTM A106 iBanga C lukhetho oludumileyo.
