Phakathi kwemibhobho emininzi, eyona nto isebenzayo ngumbhobho wensimbi ongenamthungo, ongumbhobho oqinileyo, kungekhona nje ngenxa yoluhlu olubanzi lwemimandla yesicelo kunye nobubanzi balo mbhobho, kodwa kubaluleke kakhulu ngenxa yomgangatho ophezulu wombhobho wensimbi ongenamthungo. .Emva koko, umgangatho wepayipi yensimbi engenamthungo isizathu sokuba olu hlobo lombhobho lunokukhuthazwa kwaye luphuhliswe kwintsimi yoshishino.Umgangatho wemibhobho yensimbi engenamthungo ulunge kakhulu, ochongwa yinkqubo yokuvelisa eyinkimbinkimbi yemibhobho yensimbi engenamthungo.Isici esikhulu semibhobho yensimbi engenamthungo kukuba udonga lombhobho alunamibhobho (lunokumelana noxinzelelo oluphezulu), ngelixa iibhobho eziqhelekileyo zinemibhobho ecacileyo.Ngenxa yobukhulu obuncinci bombhobho wensimbi ongenamthungo, olu hlobo lombhobho lunokusetyenziswa kwaye lukhuthazwe kwintsimi yoshishino.
Imibhobho yentsimbi engenamthungo isetyenziswa kakhulu.Imibhobho yentsimbi engenamthungo yenjongo ngokubanzi iqengqeleke ukusuka kwintsimbi eqhelekileyo yekhabhoni okanye intsimbi yealloy enemveliso enkulu.Intsimbi yekhabhoni eqhelekileyo yahlulwe kakhulu ibe:I-ASTM A106 / A53 GR.B ipayipi yentsimbi engenamthungo, API 5L GR.B umbhobho wentsimbi ongenamthungo, intsimbi yengxubevange yahlulwe ikakhulu: 15CrMo ingxubevange umbhobho intsimbi ingenamthungo, 30CrMo ingxubevange umbhobho intsimbi engenamthungo, 42CrMo ingxubevange umbhobho intsimbi ingenamthungo,20Cr ingxubevange intsimbi umbhobho ingenamthungo, 40Cr ingxubevange intsimbi umbhobho ingenamthungo, 27SiMn ingxubevange umbhobho wentsimbi engenamthungo.
Zisetyenziswa ikakhulu njengemibhobho okanye iinxalenye zesakhiwo sokuhambisa ulwelo.Umbhobho wensimbi osemgangathweni ophezulu owenziwe ngolu hlobo lwensimbi lusetyenziswa kakhulu kwiipropu ze-hydraulic, iisilinda zegesi eziphezulu, i-boilers ephezulu yoxinzelelo, izixhobo zesichumisi, ukuchithwa kwepetroleum, i-automobile half-axle sleeves, iinjini ze-diesel, njl.
