Ngokweemeko ezahlukeneyo, izinto zetsimbi zifudumala kwiqondo lokushisa elifanelekileyo kwaye zigcinwe zifudumele, kwaye zipholile ngeendlela ezahlukeneyo zokutshintsha isakhiwo se-metallographic yezinto zetsimbi kunye nokufumana iimpawu ezifunekayo zesakhiwo. Le nkqubo ibizwa ngokuba yintsimbi yonyango lobushushu. Ziziphi iinkqubo ezintathu ezibandakanyiweyo kunyango olushushu lwe-carbon steel tubes?

Ukunyangwa kobushushu bezinto zetsimbi kuhlulwe kunyango lobushushu ngokubanzi, unyango lobushushu bomhlaba kunye nonyango lobushushu bekhemikhali. Unyango olushushu lwe-carbon seamless steel tubes luthatha ngokubanzi unyango lobushushu.

Imibhobho yentsimbi kufuneka ihambe kwiinkqubo ezisisiseko ezifana nokufudumeza, ukugcinwa kobushushu kunye nokupholisa ngexesha lonyango lobushushu. Kwezi nkqubo, iibhobho zentsimbi zinokuba neziphene ezisemgangathweni. Iziphene zokunyanga ukushisa kweemibhobho zetsimbi zibandakanya ubukhulu becala isakhiwo esingafanelekanga kunye nokusebenza kweemibhobho zetsimbi, imilinganiselo engafanelekanga, i-face cracks, i-scratches, i-oxidation enzima, i-decarburization, i-overheating okanye i-overburning, njl.

Inkqubo yokuqala yonyango lwe-carbon steel ityhubhu yokushisa kukufudumala. Kukho amaqondo obushushu amabini ahlukeneyo: enye kukufudumeza ngaphantsi kwendawo ebalulekileyo i-Ac1 okanye i-Ac3; enye ifudumeza ngaphezu kwendawo ebalulekileyo i-Ac1 okanye i-Ac3. Ngaphantsi kwala maqondo okushisa amabini, ukuguqulwa kwesakhiwo sombhobho wensimbi kuhluke ngokupheleleyo. Ukufudumala ngaphantsi kwendawo ebalulekileyo ye-Ac1 okanye i-AC3 ikakhulu ukuzinzisa isakhiwo sensimbi kunye nokuphelisa uxinzelelo lwangaphakathi lombhobho wensimbi; Ukufudumeza okungaphezulu kwe-Ac1 okanye i-Ac3 kukwenza intsimbi.

Inkqubo yesibini ye-carbon steel ityhubhu yonyango lokushisa kukugcina ubushushu. Injongo yalo kukufaniswa kobushushu bokufudumala kombhobho wensimbi ukufumana isakhiwo sokufudumeza esifanelekileyo.

Inkqubo yesithathu yonyango lwe-carbon steel ityhubhu yokushisa iyapholisa. Inkqubo yokupholisa yinkqubo ephambili yonyango lobushushu bombhobho wentsimbi, omisela ubume be-metallographic kunye neempawu zomatshini wombhobho wentsimbi emva kokupholisa. Kwimveliso yangempela, kukho iindlela ezahlukeneyo zokupholisa kwimibhobho yensimbi. Iindlela zokupholisa eziqhelekileyo ezisetyenziswayo ziquka ukupholisa isithando somlilo, ukupholisa umoya, ukupholisa ioli, ukupholisa i-polymer, ukupholisa amanzi, njl.
