Eyona isetyenziswa ngokuqhelekileyo kwinkqubo yokugaya ioli yi-API ye-oil casing enikezelwa yi-Hunan Great Steel Pipe Co., Ltd. Ikwasetyenziswa ngokubambisanaimibhobho yokomba, iikhola zokomba, imibhobho engundoqo, kunye nemibhobho yentsimbi yokomba enobubanzi obuncinane.Umsebenzi oyintloko we-API ye-oil casing kukuxhasa udonga lweoli ye-oyile ngexesha lenkqubo yonke yokugaya kwaye emva kokugqitywa, enokuqinisekisa ukusebenza okuqhelekileyo kweoli yeoli.

Umbhobho we-oyile we-API owenziwe yi-Hunan Great Steel Pipe Co., Ltd luhlobo lombhobho ohambisa i-petroleum kunye nezinye izinto eziluhlaza.Iimfuno zobugcisa zombhobho we-oyile we-API obonelelwa nguHunan Great Steel Pipe Co., Ltd nazo zingqongqo.Phakathi kwazo, eyona mfuneko ingqongqo liqondo lobushushu, elifuna ubushushu obuhambelanayo kwinqanaba ngalinye lokucutshungulwa.Ngokomzekelo, i-AC1 yensimbi ye-27MnCrV ihambelana nokushisa kwe-736 degrees Celsius.Ubushushu bokufudumala kufuneka bulawuleke phakathi kwama-740-810 degrees Celsius ngexesha lokucima ubushushu obuphantsi.Qinisekisa ukuba iqondo lokushisa elingaphantsi kweqondo lokushisa liyi-780 degrees, kwaye ixesha lokufudumala lingaphezu kwemizuzu eyi-15;iqondo lobushushu lokuchithwa kwe-API ye-oyile ye-oyile enikezelwa yi-Hunan Great Steel Pipe Co., Ltd emva kokucima kufuneka ilawulwe kwii-degrees ze-630, kwaye ukutshisa kufuneka kulawulwe.Ixesha kufuneka libe ngaphezu kwemizuzu engama-50.Ukuba ufuna ukuphucula ukuqina kwe-oyile ye-API, ukushisa kufuneka kulawulwe phakathi kwe-α + γ, kwaye kuyafuneka ukuba ucime i-oil casing ye-API ngelixa ugcina inxalenye ye-ferrite edibeneyo.Ke ngoko, i-API ye-oyile ye-oyile iphathwa ngubushushu ngokucinywa kobushushu obungaphantsi, obunokuphucula ngcono amandla e-oyile ye-API, kunye nokuphucula ukuqina kwempembelelo kunye nokumelana nomonakalo we-API yeoli.

Ulawulo olungqongqo kufuneka lwenziwe ngexesha lokunyangwa kobushushu bombhobho we-oyile we-API onikezelwe ngu-Hunan Great Steel Pipe Co., Ltd. Kungale ndlela kuphela umgangatho we-API we-oyile yombhobho we-oyile onikezelwe nguHunan Great Steel Pipe Co., Ltd. iqinisekisiwe.Inokuqina okuphezulu kunye nokunye ukusebenza ngexesha lokusetyenziswa.I-API ye-oyile ye-oyile ebonelelwa ngu-Hunan Great Steel Pipe Co., Ltd ithatha indlela yokucima i-cryogenic yokunciphisa uxinzelelo ngexesha lokucima.Ngokuqhelekileyo, iqondo lokushisa lokucima i-cryogenic liphantsi kunokushisa okuqhelekileyo, ngoko akulula ukubangela i-Hunan ngexesha lokucima.I-deformation ye-API ye-oyile ye-oil casing ebonelelwa yi-Great Steel Pipe Co., Ltd. Ukusebenzisa le ndlela yonyango ayinakuqinisekisa kuphela imveliso eqhelekileyo kodwa inikezela ngezinto eziphathekayo zokucutshungulwa kwecingo olulandelayo.
