Emva kokuba i-oyile ye-oyile yamkele le ndlela yonyango lobushushu, inokuphucula ngokufanelekileyo ukuqina kwempembelelo, amandla okuqina, kunye nokusebenza okuchasene nokutshabalalisa kwe-oyile, ukuqinisekisa ixabiso elihle elisetyenziswayo.I-petroleum casing yimathiriyeli yombhobho efunekayo yokugaya ioli kunye negesi yendalo, kwaye kufuneka ibe nokusebenza kakuhle ekusebenziseni.Ulawulo oluhlukeneyo lokushisa lukhethwa kumacandelo ahlukeneyo obushushu be-oyile ye-oyile.Ukufudumeza kufuneka kuveliswe ngokweqondo elithile lobushushu.Yentsimbi ye-27MnCrV, AC1=736℃, AC3=810℃, iqondo lokushisa kufuneka libe ngama-630℃emva kokucima, kunye nokufudumala ukufudumeza Ixesha lokubamba yimizuzu engama-50;ubushushu bokufudumala bukhethwa ukusuka kwi-740 ukuya kwi-810°C ngexesha lokucima ubushushu obuphantsi.Ubushushu bobushushu bokucima kobushushu obungaphantsi bungama-780℃, kwaye ixesha lokubamba ukucima ukufudumala yimizuzu eyi-15.Kuba sub-ubushushu quenching ishushu kwiα+γ ummandla wesigaba ezibini, ukucima kwenziwa kwimeko ye-ferrite yendawo enganyibilikiyo, ukugcina amandla aphezulu ngelixa ufezekisa ukuqina.ukuphucula.

Unyango olushushu lwe-oyile ye-oyile kufuneka lwenziwe ngokungqongqo ukuqinisekisa ukuba i-oyile ye-oyile eveliswayo inomgangatho ophezulu wemveliso kunye nokusebenza, kwaye kuphela xa isetyenzisiweyo ingabonisa ixabiso elihle lokusetyenziswa kunye nokusebenza, ukunamathela kumandla aphezulu kunye nokuqina, kunye nonyango lobushushu iindlela ezahlukeneyo.Ngelo xesha, ukushisa okuphantsi kweqondo lokushisa kuphantsi kunokushisa okuqhelekileyo, okunciphisa uxinzelelo lokucima kunye nokunciphisa ukucima ukucima.Oku kuqinisekisa ukusebenza kakuhle kwemveliso yonyango lobushushu lwe-oyile ye-oyile kwaye ibonelela ngeemeko ezilungileyo zokucutshungulwa kocingo olulandelayo.Impahla engekasilwa.

Okwangoku, inkqubo isetyenziswe kwiindawo ezahlukeneyo zokulungisa umbhobho wensimbi.Idatha yoqinisekiso lomgangatho ibonisa ukuba amandla okuqina kombhobho wensimbi ophethwe ngubushushu yi-Rm910-940MPa, amandla okuvelisa i-Rt0.6820-860MPa yi-100% efanelekileyo, kunye nokuqina kwempembelelo ye-Akv65-85J idatha ibonisa ukuba i-27MnCrV ipayipi yensimbi sele isingxobo sepetroleum esikumgangatho ophezulu kakhulu.Ngakolunye uhlangothi, ikwabonisa ukuba inkqubo yokucima ubushushu obungaphantsi kobushushu buyindlela ebalaseleyo yokuphepha ukunyanzeliswa kobushushu obuphezulu ekuvelisweni kweemveliso zetsimbi.
