Ngemuva kokuthi isikhwama sikawoyela samukele le ndlela yokwelapha ukushisa, ingathuthukisa ngempumelelo ukuqina komthelela, amandla aqinile, nokusebenza okulwa nokucekela phansi kwegobolondo likawoyela, iqinisekise inani elihle elisetshenziswayo.I-petroleum casing iyimpahla yepayipi edingekayo yokumba uwoyela negesi yemvelo, futhi idinga ukusebenza kahle uma isetshenziswa.Ukulawulwa kwezinga lokushisa okuhlukile kukhethelwa izigaba zokushisa ezihlukene ze-oyela casing.Ukushisa kudinga ukukhiqizwa ngokwezinga elithile lokushisa.Ngensimbi engu-27MnCrV, AC1=736℃, AC3=810℃, izinga lokushisa kufanele libe ngu-630℃emva kokucisha, nokushisa ukushisa Isikhathi sokubamba imizuzu engama-50;izinga lokushisa lokushisa likhethwa kusuka ku-740 kuya ku-810°C ngesikhathi sokucisha izinga lokushisa elingaphansi.Izinga lokushisa lokushisisa le-sub-temperature quenching ngu-780℃, futhi isikhathi sokubamba sokucisha ukushisa imizuzu eyi-15.Ngoba i-sub-temperature quenching iyashiswa ku-α+γ indawo enezigaba ezimbili, ukucisha kwenziwa endaweni ye-ferrite yendawo engancibilikisiwe, igcina amandla aphezulu ngenkathi ifinyelela ukuqina.ngcono.

Ukwelashwa kokushisa kwesikhwama samafutha kufanele kwenziwe ngokuqinile ukuze kuqinisekiswe ukuthi isikhwama sikawoyela esikhiqiziwe sinekhwalithi enhle kakhulu nokusebenza kahle komkhiqizo, futhi kuphela lapho sisetshenziswa lapho singabonisa khona ukusetshenziswa okuhle nokusebenza kahle, ukunamathela kumandla aphezulu kanye nokuqina, kanye nokwelashwa kokushisa izindlela ezahlukene.Ngesikhathi esifanayo, izinga lokushisa eliphansi lokushisa eliphansi liphansi kunokushisa okujwayelekile, okunciphisa ukucindezeleka kokucisha futhi kunciphisa ukuguqulwa kokucisha.Lokhu kuqinisekisa ukusebenza kahle kokukhiqizwa kokwelashwa kokushisa kwe-oil casing futhi kunikeza izimo ezinhle zokucubungula ucingo olulandelayo.impahla eluhlaza.

Njengamanje, le nqubo isetshenziswe ezindaweni ezahlukene zokucubungula amapayipi ensimbi.Idatha yokuqinisekisa ikhwalithi ikhombisa ukuthi amandla aqinile wepayipi lensimbi eliphethwe ukushisa ngu-Rm910-940MPa, amandla okukhiqiza i-Rt0.6820-860MPa afaneleka ngo-100%, kanye nokuqina komthelela we-Akv65-85J kubonisa ukuthi Ipayipi lensimbi elingu-27MnCrV selivele i-petroleum casing yezinga eliphezulu lensimbi ephezulu kakhulu.Ngakolunye uhlangothi, iphinde ibonise ukuthi inqubo yokucisha izinga lokushisa elingaphansi kuyindlela enhle kakhulu yokugwema ukushisa okuphezulu kwezinga lokushisa ekukhiqizeni imikhiqizo yensimbi.
