Ipayipi lomugqa: Kuwukuthutha uwoyela, igesi noma amanzi akhishwe emhlabathini aye emabhizinisini embonini kawoyela negesi ngepayipi lomugqa. Amapayipi omugqa ahlanganisa amapayipi angenamthungo nahlanganisiwe. Amaphethelo amapayipi ayiziphetho ezisicaba, amaphethelo anentambo kanye namaphethelo esokhethi; izindlela zokuxhuma ukushisela kokuphela, ukuxhumana kokuxhuma, ukuxhumana kwesokhethi, njll.

Igama lesiShayina Ipayipi yomugqa Imininingwane yepayipi yomugqa 10.3-2032×1.7-39.7mm Izinga lokusebenzisaGB/T9711-2017/I-API SPEC 5LSebenzisa ukuthuthwa kwegesi, amanzi kanye namafutha embonini yegesi yemvelo

Isifinyezo sepayipi lomugqa
Ukusetshenziswa: Kusetshenziselwa ukuthuthwa kwegesi, amanzi kanye namafutha embonini kawoyela negesi

I-API SPEC 5L-2018(Incazelo yepayipi lomugqa) ihlanganiswa futhi ishicilelwe yi-American Petroleum Institute futhi isetshenziswa kakhulu emhlabeni jikelele.

Ngokuya ngezimfuneko zokusebenza ezahlukene zeGB/T9711-2017Amapayipi ensimbi epayipi, ukufudumala kungahlukaniswa ngezinhlobo ezilandelayo ngokuya ngokushisa kokufudumala:
1. Ukushisa okuphansi (ama-degree angu-150-250)
Isakhiwo esitholakala ngokushisa okuphansi yi-martensite eqinisiwe. Inhloso yaso ukunciphisa ukucindezeleka kwangaphakathi kokucima kanye nokuqhekeka kwensimbi eqinisiwe ngenkathi kugcinwa ubulukhuni obuphezulu kanye nokumelana nokuguguleka okuphezulu kwensimbi eqinisiwe, ukuze kugwenywe ukuqhekeka noma ukulimala kwangaphambi kwesikhathi ngesikhathi sokusetshenziswa. Isetshenziswa kakhulu kumathuluzi ahlukahlukene okusika anekhabhoni ephezulu, amathuluzi okulinganisa, amapayipi ensimbi epayipini le-GB/T9711, amabheringi ajikelezayo kanye nezingxenye ezifakwe i-carburized, njll. Ubulukhuni ngemva kokushisa ngokuvamile yi-HRC58-64.
2. Ukushisa okuphakathi nendawo (ama-degree angu-250-500)
Isakhiwo esitholwe ngokushisa okuphakathi yi-troostite eqinisiwe. Inhloso yaso ukuthola amandla aphezulu okukhiqiza, umkhawulo wokunwebeka kanye nokuqina okuphezulu. Ngakho-ke, sisetshenziswa kakhulu ekwelapheni amapayipi ensimbi ahlukahlukene epayipi le-GB/T9711 kanye nezikhunta zokusebenza ezishisayo, kanti ubunzima ngemva kokushisa ngokuvamile yi-HRC35-50.
3. Ukushisa okuphezulu (ama-degree angu-500-650)
Isakhiwo esitholakala ngokushisa okuphezulu yi-troostite eqinisiwe. Ukwelashwa kokushisa okuhlanganisa ukucima kanye nokushisa okuphezulu kuvame ukubizwa ngokuthi ukucima kanye nokwelashwa kokushisa, inhloso yaso ukuthola izakhiwo eziphelele zemishini ezinamandla amahle, ubulukhuni, i-plasticity kanye nokuqina. Ngakho-ke, isetshenziswa kabanzi ezingxenyeni ezibalulekile zesakhiwo sezimoto, amapayipi ensimbi epayipi le-GB/T9711, amathuluzi omshini, njll., njengezinduku zokuxhuma, amabhawodi, amagiya kanye nemishayo. Ubulukhuni ngemva kokushisa ngokuvamile buyi-HB200-330.
Amazinga ayinhloko okukhiqiza amapayipi epayipi (API5L/I-GB/T 9711-2017):

Qaphela: Kunezinhlamvu eziningi ezengeziwe ngemva kwe-Izinga elijwayelekile le-API 5Lizinga lensimbi yepayipi, okumelela okulandelayo:
Kusho ukuthini ukuthi izinga lensimbi yepayipi u-N? "N" lisho ukuthi kujwayelekile ukwelashwa kokushisa
Kusho ukuthini ukuthi izinga lensimbi yepayipi elithi Q? Igama elithi "Q" lisho ukuthi ukucima + ukufudumala kokushisa
Kusho ukuthini ukuthi i-NS yensimbi yombhobho isho ukuthini? Igama elithi "NS" lisho ukuthi "normalizing" kanye nokumelana ne-asidi nokugqwala,
Kusho ukuthini i-QS yezinga lensimbi yepayipi? Igama elithi "QS" limelela ukucima + ukwelashwa kokushisa okushisayo kanye nokumelana ne-asidi nokugqwala
