Iyo inonyanya kushandiswa mukuchera mafuta ndeye API mafuta casing inopihwa neHunan Great Steel Pipe Co., Ltd. Inoshandiswawo pamwe chetedhirai mapombi, makorokoza, pombi dzepakati, uye pombi dzesimbi dzine dhayamita diki.Basa guru re API mafuta casing ndere kutsigira tsime remafuta madziro panguva yese yekuchera uye mushure mekupedzwa, iyo inogona kuve nechokwadi chekushanda kwese kwemafuta mutsime.

Iyo API mafuta casing pombi inopihwa neHunan Great Steel Pipe Co., Ltd imhando yepombi inotakura peturu uye zvimwe zvigadzirwa.Izvo zvinodiwa zvehunyanzvi zveiyo API mafuta casing pombi inopihwa neHunan Great Steel Pipe Co., Ltd zvakare yakasimba.Pakati pavo, chinonyanya kuomesesa tembiricha, inoda tembiricha inoenderana mune yega yega nhanho yekugadzirisa.Semuenzaniso, iyo AC1 ye27MnCrV simbi inoenderana nekudziya kwe736 degrees Celsius.Kupisa kwekushisa kunofanirwa kudzorwa pakati pe740-810 madhigirii celsius panguva yekudzima tembiricha.Ita shuwa kuti tembiricha yekudzima tembiricha ndeye 780 madhigirii, uye nguva yekudziya inodarika maminitsi gumi nemashanu;kupisa kwekuparadza kweiyo API mafuta casing yakapihwa naHunan Great Steel Pipe Co., Ltd mushure mekudzima kunofanirwa kudzorwa pa630 madhigirii, uye kupisa kunofanirwa kudzorwa.Nguva yacho inofanira kuva pamusoro pemaminitsi makumi mashanu.Kana iwe uchida kuvandudza kuoma kweiyo API mafuta casing, tembiricha yekudziya inofanirwa kudzorwa pakati pe α + γ, uye inodiwa kudzima iyo API mafuta casing uchichengeta chikamu cheyakanyungudika ferrite.Naizvozvo, API oiri casing inorapwa nekupisa-kupisa nekudzimisa, izvo zvinogona kuvandudza simba rekusimba reAPI mafuta casing, uye kugadzirisa kuoma kwemhedzisiro uye kukuvadza kuramba kweAPI mafuta casing.

Kudzora kwakasimba kunofanirwa kuitwa panguva yekupisa kwepiipi yepiipi yepiipi yemafuta inopihwa neHunan Great Steel Pipe Co., Ltd. Nenzira iyi chete ndipo panogona kuita mhando yepiipi yepiipi yemafuta yeAPI inopihwa neHunan Great Steel Pipe Co., Ltd. guaranteed.Iyo ine yakanyanya kuoma uye kumwe kuita panguva yekushandiswa.Iyo API mafuta casing inopihwa naHunan Great Steel Pipe Co., Ltd inotora cryogenic quenching kugadzirisa nzira yekudzikisa kushushikana kwekuchinja panguva yekudzima.Kazhinji, tembiricha yakadaro cryogenic quenching yakaderera pane yakajairika tembiricha, saka hazvisi nyore kukonzera Hunan panguva yekudzima.The deformation of API oil casing inopiwa neGreat Steel Pipe Co., Ltd. Kushandisa nzira iyi yekurapa haigoni kungoita kuti ive nechokwadi chekugadzirwa kwemazuva ose asiwo kupa zvinhu zvakasvibirira zvekuzotevera kugadzirisa waya.
