Kunezinhlobo eziningana zokuthambisa amapayipi

Ngokwezidingo zokusebenza kwepayipi lensimbi ye-GB/T9711.1, ngokuya ngezinga lokushisa elihlukile, lingahlukaniswa ngezinhlobo ezilandelayo zokushisa:

[1] Izinga lokushisa eliphansi (150-250 degrees)
I-microstructure etholwe ngokushisa okuphansi kwezinga lokushisa yi-martensite epholile.Inhloso yayo ukunciphisa ukucindezeleka okucishayo kanye nokuqina kwensimbi eqinile esakhiweni sokugcina ubulukhuni bayo obuphezulu nokumelana nokugqoka okuphezulu, ukuze kugwenywe ukuqhekeka noma ukulimala ngaphambi kwesikhathi ngesikhathi sokusetshenziswa.Isetshenziswa kakhulu kuzo zonke izinhlobo zamathuluzi okusika ikhabhoni ephezulu, amathuluzi okulinganisa, ipayipi lensimbi le-GB/T9711.1, amabhere aginqikayo kanye nezingxenye zokungcwaba, njll.

[2] Ukushisa okumaphakathi kwezinga lokushisa (250-500 degrees)
I-microstructure etholwe ngokufutheka okumaphakathi yi-trostite epholile.Inhloso ukuthola amandla esivuno esiphezulu, umkhawulo wokunwebeka kanye nokuqina okuphezulu.Ngakho-ke, isetshenziswa kakhulu kuzo zonke izinhlobo zepayipi lensimbi lepayipi le-GB/T9711.1 kanye nokwelashwa kwesikhunta esishisayo, ngemva kokuqina kokushisa ngokuvamile kuyi-HRC35-50.

[3] Ukushisa okuphezulu kwezinga lokushisa (500-650 degrees)
I-microstructure etholwe ngokushisa okuphezulu kwezinga lokushisa i-sortensite epholile.Ngokuvamile, ukwelashwa kokushisa okuhlangene nokucisha kanye nokushisa kubizwa ngokuthi ukucisha nokuthulisa.Inhloso yawo ukuthola izakhiwo eziphelele zemishini zamandla, ubulukhuni, ipulasitiki kanye nokuqina.Ngakho-ke, isetshenziswa kabanzi ezimotweni, ipayipi lensimbi le-GB/T9711.1, amathuluzi omshini nezinye izingxenye ezibalulekile zesakhiwo, njengenduku yokuxhuma, ibholiti, igiya kanye ne-shaft.Ubulukhuni ngemva kokushisa ngokuvamile buyi-HB200-330.

Okujwayelekile

I-API SPEC 5L -- American Petroleum Institute Standard

I-GB/T9711 -- Izinga likazwelonke lase-China

Isebenzisa

Isetshenziselwa i-oxygen, amanzi kanye nepayipi elihambisa uwoyela embonini ye-petroleum negesi yemvelo

Ukukhiqizwa okuyinhloko kwamabanga amapayipi ensimbi:

B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485
