Ukwethulwa kwepayipi lensimbi engagqwali i-321

321 amapayipi ensimbi engagqwaliyenziwe ngezinto ezingama-321 zensimbi engagqwali.

1. Ipayipi lensimbi engenamthungo engu-321 lisetshenziselwa ukukhiqiza ipayipi lesitimu elishisa kakhulu le-boiler enengcindezi ephansi nemaphakathi, amapayipi amanzi abilayo namapayipi esimusi ashisa kakhulu asetshenziswa kumabhoyela esitimela, amapayipi intuthu amakhulu namancane, namapayipi amahle ekhabhoni abandayo namapayipi ensimbi angenamthungo agoqiwe.
2. 321 ipayipi lensimbi engagqwali: lalivame ukukhiqiza izinsimbi ezinhle ze-carbion, izinsimbi ze-alloy nezinsimbi ezingenasici ezishisayo ezisetshenziselwa ukucindezela ipayipi likabhayela.Le mibhobho ye-bolier ivame ukusetshenziswa ekushiseni okuphezulu nokucindezela okukhulu.Amapayipi azokhipha i-oxyd futhi agqwale ngenxa yentuthu yokushisa ephezulu nesitimu.Ngakho-ke, amapayipi kufanele abe nezinga eliphezulu lokumelana, i-oxideze reistence ikhono, futhi abe nokuzinza okuhle kwenhlangano, i-hydraulic prop tube.
3. Izinombolo zensimbi ze-321 insimbi engagqwali: 304, 321, 316, 317, 310, njll.
4. Izinombolo zamapayipi ensimbi ye-Alloy: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njll. Izinombolo zensimbi engagqwali eshisayo: 1Cr18Ni9,1Cr.Lindela ukuqinisekisa izakhi zamakhemikhali kanye nezakhiwo zemishini, sizokwenza ukucindezela kwamanzi, ukuhlola ukuvutha kanye nokuthambisa.
5. 321amapayipi ensimbi engagqwaliizolethwa ekucutshungulweni okushisayo.Uma kungenjalo, ukwakheka kwe-microscopic, usayizi wokusanhlamvu kanye nesendlalelo se-decarburized kudinga ukufika ezingeni elijwayelekile.Amapayipi ensimbi engenamthungo asetshenziselwa ukubhola komhlaba kanye nokubhola uwoyela.Ukumba ukwakheka kwamadwala, amanzi angaphansi komhlaba, uwoyela, igesi yemvelo kanye nemithombo yamaminerali ngokuqinisekile, sizomba kahle ngomshini wokumba.

Ukubuyisela uphethiloli kanye negesi yemvelo kudinga ukumba kahle, ipayipi lensimbi engenamthungo elisetshenziselwa ukubhola komhlaba kanye nokubhola uwoyela liyithuluzi eliyinhloko lokumba umthombo.Kubandakanya ishubhu elingaphakathi eliwumgogodla, ishubhu elingaphakathi elingaphakathi, uphayiphi, induku yenkunzi, njll. Ngenxa yokuthi amapayipi omthombo wokumba adinga ukubekwa endaweni eyizinkulungwane zamamitha ukuze asebenze, sidinga amapayipi alloy angu-1cr5mo.
