Umbhobho wentsimbi engenamthungo wekhabhoni ubhekisa kumbhobho owenziwe ngentsimbi yekhabhoni engenazo naziphi na izihlanganisi okanye imithungo edibeneyo, kwaye i-billet eqinileyo ikhutshwa ngedayethi ukuze yenze umbhobho onemilo nobukhulu obufunekayo. Umbhobho wentsimbi engenamthungo wekhabhoni uthandwa ngenxa yokuqina kwawo okugqwesileyo, amandla okutsalwa kunye nokumelana nokugqwala, okwenza ukuba ulungele uluhlu olubanzi lwamashishini kuquka ioyile negesi, iimoto kunye nolwakhiwo.
Enye yezona ntlobo zidumileyo zombhobho wesinyithi ongenamthungo wekhabhoni yiIbanga B le-A106, eyimigangatho ye-ASTM yepayipi yentsimbi yekhabhoni engenamthungo yenkonzo yobushushu obuphezulu. Inomxholo ophezulu wekhabhoni oyi-0.30%, nto leyo eyenza ukuba ilungele ukusetyenziswa okufuna ubushushu obuphezulu kunye noxinzelelo. Ikwafanelekile ukusetyenziswa koxinzelelo oluphantsi kunye nobushushu obuphantsi, kunye nokuwelda kunye nokurhawuzelela.
Elinye ibakala elidumileyo leliI-API 5L Ibanga B, eyindlela eqhelekileyo yemibhobho yentsimbi engenamthungo nedibeneyo kwiinkqubo zokuhambisa imibhobho kwishishini leoyile negesi. Inomxholo ophezulu wekhabhoni oyi-0.30%, nto leyo eyenza ukuba ilungele ukusetyenziswa kwiindawo ezixineneyo nezishushu kakhulu.
Ukongeza kudidi, izinto zombhobho wentsimbi engenamthungo yekhabhoni nazo zibaluleke kakhulu. Izinto eziqhelekileyo ziquka i-SAE 1020, enomxholo ophantsi wekhabhoni kwaye ilungele ukugoba, ukuflanga kunye nemisebenzi efanayo yokwenza, kunye ne-SAE 1045, enomxholo ophezulu wekhabhoni kwaye ilungele ukusetyenziswa okufuna ubulukhuni, ukuqina kunye nokumelana nokuguguleka.
Ezinye izinto ziquka i-ASTM A519 Grade 4130 yemigca ye-hydraulic enoxinzelelo oluphezulu kunye neetyhubhu ze-oyile, kunye ne-ASTM A106 Grade C enomxholo ophezulu wekhabhoni we-0.35% kwizicelo ezifuna ukumelana nokugqwala okuphezulu.
Ukuqukumbela, imibhobho yentsimbi engenamthungo yekhabhoni ibalulekile kuluhlu olubanzi lwamashishini kwaye ukhetho lomgangatho kunye nezinto ezisetyenzisiweyo luxhomekeke kwisicelo esithile. I-A106 Grade B kunye ne-API 5L Grade B ziimpawu ezidumileyo, ngelixa izixhobo ezifana ne-SAE 1020, i-SAE 1045,Ibanga le-ASTM A519 4130, kunye ne-ASTM A106 Grade C zikhetho ezidumileyo.
