Ukukhetha Okubalulekile Kwezindololwane Zezinqe Zokushisela

Ukukhethwa kwezinto zokushisela izindololwane ze-butt kuncike ezintweni ezifana nokucindezela kwesistimu yamapayipi, izici ezimaphakathi, nezimo zemvelo. Izinto ezijwayelekile zifaka:

 

Insimbi ye-carbon: Izindleko eziphansi kodwa ukumelana nokugqwala okungekuhle, kulungele-ingcindezi ephansi,{1}}izinga lokushisa elivamile,{2}}nezimo ezingagqwali.

Insimbi engagqwali: Ukumelana nokugqwala okuhle kakhulu kanye{0}}nokuqina kwezinga lokushisa okuphezulu, okusebenzayo endaweni ebolayo, izidingo-zezinga lokuhlanzeka, kanye{2}}nezinga lokushisa eliphezulu,{3}}izimo zengcindezi ephansi.

Insimbi ye-alloy: Amandla-ezinga lokushisa eliphezulu, ukumelana nokunyakaza, noma{1}}ukumelana nezinga lokushisa eliphansi, kulungele{2}}izinga lokushisa eliphezulu/eliphezulu{3}}ingcindezi noma ephansi{4}}izinga lokushisa/{5}}phezulu{5}}amapayipi okucindezela.

Izinto ezikhethekile(isb., i-nickel-ama-alloys asekelwe, i-titanium, ne-titanium alloys): Isetshenziswa ezimweni ezimbi kakhulu njengokugqwala okuqinile noma amazinga okushisa aphakeme-.
Zonke izinto ezisetshenziswayo zihambisana nezindinganiso ezihambisanayo zasekhaya nezamazwe ngamazwe.

 

Izidingo Zobuchwepheshe

Lezi zihlanganisa yonke inqubo yokukhiqiza:

Izinqubo zokukhiqiza: Kuhlanganisa ukusunduza (-kuya{1}}kububanzi obumaphakathi, obuncane-izindololwane ezinezindonga), ukucindezela (okukhulu-okubanzi,{4}}izindololwane ezinezindonga), kanye nokwakheka okushiselwe ({5}}ngezindololwane ezinkulu ezinobubanzi ezinezigaxa zokushisela).

Ukubekezelelana kwe-Dimensional: Ukuvumelana nezindinganiso ezifanele, ezinezidingo ezicacile zokuchezuka kwe-engeli, ububanzi bangaphandle, ukujiya kodonga, nerediyasi yokugoba.

Izidingo zokushisela: Ukugxila ekwakhiweni kwe-groove, ukufaniswa kwezinto zokushisela, izindlela zokushisela, nokwelashwa{0}}ngeposi.

Ukwelashwa kokushisa: I-Annealing, ukwelashwa kwesixazululo, njll., ukususa ingcindezi noma ukukhulisa ukusebenza kahle, kuye ngezinto ezibonakalayo.

Ukwelashwa kwendawo: Ukucekela phansi, ukupenda, noma ukwenza uthayela ngensimbi ye-carbon; pickling kanye passivation for insimbi engagqwali.

 

Ukuhlola

Ukuhlola kusebenza kuyo yonke inqubo kusukela ezintweni ezingavuthiwe kuye emikhiqizweni eqediwe:

Ukuhlola impahla eluhlaza: Ukuqinisekisa izitifiketi zekhwalithi nokwenza ukuhlolwa ngokomzimba namakhemikhali.

-Iyahlolwa: Kubandakanya ukuhlola kobukhulu nokuqapha inqubo yokushisela.

Iqedile ukuhlola umkhiqizo: Okuhlanganisa ukuhlolwa okubonakalayo, ukuhlola{0}}okungonakalisi (i-radiographic, i-ultrasonic, izinhlayiyana zikazibuthe/ukuhlola ukungena, njll.), ukuhlolwa kwengcindezi (i-hydrostatic noma i-pneumatic), nokunye ukuhlola okufana nokuhlola ubulukhuni nokuhlaziywa kwe-metallographic.
