Ingcaciso yeMveliso

1. 321 umbhobho wentsimbi.Umbhobho wentsimbi ongenamthungo (GB14976-2002) usetyenziselwa ukwenza imibhobho yomphunga eshushu kakhulu, imibhobho yamanzi abilayo kunye nemibhobho yebhoyila eshushu kakhulu, imibhobho yomsi emikhulu, imibhobho emincinci yomsi kunye nemibhobho yezitena zearch yezakhiwo ezahlukeneyo.Ikhabhoni yolwakhiwo lwentsimbi eshushu-isolwe ngokubanda (eqengqelekayo) iityhubhu zentsimbi ezingenamthungo.

2. 321 imibhobho yensimbi engenasici: umgangatho ophezulu we-carbon structural steel, i-alloy structural steel kunye nentsimbi engenakunqanda ukushisa kwentsimbi engenamthungo imibhobho yentsimbi esetyenziselwa kakhulu ukwenza uxinzelelo oluphezulu kunye nemibhobho yebhoyila yomphunga.Le mibhobho yebhoyila ihlala iphantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu.Umsebenzi kunye nemibhobho iya kungena kwi-oxidation kunye nokuhlwa phantsi kwentshukumo yegesi yobushushu obuphezulu kunye nomphunga wamanzi.Ngoko ke, imibhobho yentsimbi iyadingeka ukuba ibe namandla aphezulu okunyamezela, ukuxhathisa okuphezulu kwe-oxidation, kunye nokuzinza okulungileyo kombutho.Imibhobho yepropu ye-hydraulic.

3. Amabakala ensimbi asetyenziselwa i-321 imibhobho yensimbi engenasici: 304 321 316 317 310, njl.

4. I-alloy yesakhiwo sentsimbi yombhobho wensimbi amabakala 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njl.;kukho i-stainless heat-resistant-resistant steel 1Cr18Ni9, 1Cr18Ni11Nb high-pressure boiler tubes, ngaphezu kokuqinisekisa ukubunjwa kweekhemikhali kunye neempawu zemishini, uxinzelelo lwamanzi kufuneka lwenziwe nganye nganye.Uvavanyo, uvavanyo lokuvutha kunye nokulinganisa kufuneka lwenziwe.

5. Iipayipi ze-321 zensimbi ezingenasici zihanjiswa kwimeko yokushisa ukushisa.Ukongeza, kukho iimfuno ezithile ze-microstructure, ubungakanani beengqolowa, kunye ne-decarburized layer yombhobho wensimbi ogqityiweyo.Imibhobho yentsimbi engenamthungo yokugrumba ijoloji kunye nolawulo lokwemba ioli;sebenzisa izixhobo zokugrumba ukugrumba amaqula ukuze kuphononongwe ubume bamatye angaphantsi komhlaba, amanzi aphantsi komhlaba, i-oyile, igesi yendalo kunye nemithombo yezimbiwa.Ukuhlola i-petroleum nerhasi yendalo akunakwahlulwa nangakumbi ekugrunjweni kwamaqula.Imibhobho yentsimbi engenamthungo yokugrumba kunye nokulawula zezona zixhobo ziphambili zokomba, kubandakanywa iityhubhu ezingundoqo zangaphandle, iityhubhu zangaphakathi ezingundoqo, ii-casings, kunye nemibhobho yokomba.Kuba umbhobho wokomba kufuneka ube nzulu kubunzulu bokwenziwa kweekhilomitha eziliqela ukuze usebenze, umbhobho wealloyi oyi-1cr5mo.

6. Iimeko zokusebenza zinzima kakhulu.Umbhobho wokugrumba uphantsi koxinzelelo olufana noxinzelelo, ukucinezelwa, ukugoba, ukushukuma, kunye nomthwalo wempembelelo engalinganiyo, kunye nokunxitywa kodaka namatye.Ngoko ke, umbhobho kufuneka ube namandla okwaneleyo, ukuqina, ukumelana nokunxiba kunye nokuqina kweMpembelelo, umbhobho wensimbi osetyenziswayo "DZ" (i-Geological Pinyin prefix) kunye nenombolo enye yokumela isivuno sentsimbi, amabakala ensimbi asetyenziswa ngokuqhelekileyo yi-45MnB, 50Mn DZ45;DZ50 40Mn2, 40Mn2Si;DZ55 40Mn2Mo, 40MnVB;40MnMoB ye-DZ60, 27MnMoVB ye-DZ65.Imibhobho yentsimbi ihanjiswa kwimeko yokushisa.

7. Imibhobho yokuqhekeka kwepetroleum: imibhobho engenamthungo yemibhobho yesithando somlilo, imibhobho yokutshintsha ubushushu kunye nemibhobho esetyenziswa kwiindawo zokucokisa i-petroleum.Ngokuqhelekileyo isetyenziselwa i-carbon steel high-quality (10, 20), i-alloy steel (12CrMo, 15CrMo), i-heat-resistant steel (12Cr2Mo, 15Cr5Mo), insimbi engenasici (1Cr18Ni9, 1Cr18Ni9Ti) yokuvelisa.

8. Imibhobho yentsimbi engenamthungo kwimibhobho engama-321 yensimbi engenasici (GB3087-1999) isetyenziselwa ukwenza imibhobho yomphunga eshushu kakhulu, imibhobho yamanzi abilayo kunye nemibhobho yebhoyila enobushushu obuphezulu, imibhobho yomsi emikhulu, imibhobho emincinci yomsi kunye nemibhobho yezitena ye-arch kwizakhiwo ezahlukeneyo eziphantsi kunye nezisezantsi. iibhoyila zoxinzelelo oluphakathi.Umgangatho ophezulu we-carbon structural steel hot-rolled and cold-drawn (role) iityhubhu zentsimbi ezingenamthungo.Umbhobho wentsimbi ye-321: Isetyenziselwa ikakhulu ukwenza umgangatho ophezulu wekhabhoni yentsimbi, i-alloy structural iron kunye nentsimbi engasimiyo ekwaziyo ukumelana nobushushu kwimibhobho yebhoyila yomphunga yoxinzelelo oluphezulu nangaphezulu.Le mibhobho yebhoyili isebenza phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu., Umbhobho uya kuba ne-oxidized kwaye i-corrod phantsi kwesenzo segesi ephezulu yokushisa kunye nomphunga wamanzi.Ngoko ke, umbhobho wensimbi kufuneka ube namandla aphezulu okunyamezela, ukuxhatshazwa kwe-oxidation ephezulu, kunye nokuzinza kombutho olungileyo, umbhobho we-hydraulic prop.

9. Iipayipi ze-321 zensimbi ezingenasici zihanjiswa kwimeko yokushisa ukushisa.Ukongeza, kukho iimfuno ezithile ze-microstructure, ubungakanani beengqolowa, kunye ne-decarburized layer yombhobho wensimbi ogqityiweyo.Imibhobho yentsimbi engenamthungo yokugrumba ijoloji kunye nolawulo lokwemba ioli;sebenzisa izixhobo zokugrumba ukugrumba amaqula ukuze kuphononongwe ubume bamatye angaphantsi komhlaba, amanzi aphantsi komhlaba, i-oyile, igesi yendalo kunye nemithombo yezimbiwa.
