- Ukukhethwa kwezintoizifudumezi zemibhobhobuchaphazela ngokuthe ngqo ubomi benkonzo yabo, ukusebenza kakuhle kokufudumeza, kunye nokhuseleko, kwaye kufuneka bagwetywe ngokucokisekileyo ngokusekelwe kwizinto ezingundoqo ezifana neempawu zendlela yokusebenza, ubushushu, uxinzelelo, kunye nokuhlwa.
I-1, Izinto eziphambili ezichaphazela ukukhetha izinto
Iimpawu zendlela yokusebenza:
Nokuba i-medium inomhlwa (njenge-acid-base solutions, amanzi olwandle, ulwelo lwenkunkuma yeekhemikhali, njl.);
Ingaba i-medium iqulethe ukungcola (njengamaqhekeza, i-sediment, njl., enokubangela ukuguga);
Nokuba inqanaba lokutya linqanaba lokutya okanye ibakala lamayeza (kufuneka lihlangabezane neemfuno zococeko kwaye kungabikho mvula).
Ubushushu bokusebenza:
Ukusebenza kokumelana nokushisa okuphezulu kwezinto ezahlukeneyo kuyahluka kakhulu kwiqondo lokushisa (≤ 100 ℃), ukushisa okuphakathi (100-600 ℃), kunye nokushisa okuphezulu (> 600 ℃).
uxinzelelo lokusebenza:
Uxinzelelo oluphantsi (≤ 1MPa), uxinzelelo oluphakathi (1-10MPa), uxinzelelo oluphezulu (> 10MPa), izinto eziphathekayo kufuneka zihlangabezane neemfuno zamandla omatshini phantsi koxinzelelo oluhambelanayo.
2, Izinto eziqhelekileyo kunye neemeko ezifanelekileyo
Intsimbi engatyiwa (eyona isetyenziswa kakhulu)
Ukwahlulwe ngokweemodeli ezinje nge-304, 316, 310S, njl., ukuxhathisa umhlwa kunye nokumelana nobushushu obuphezulu kuyaphuculwa ngokulandelelana:
304 intsimbi engatyiwa:ukumelana ne-corrosion jikelele (njengamanzi, umoya, i-asidi ebuthakathaka kunye ne-alkali), ixabiso eliphakathi, elilungele ukufudumeza amanzi epompo, amanzi aqhelekileyo amashishini, umoya ocinezelweyo, njl., ubushushu bokusebenza ≤ 600 ℃, uxinzelelo ≤ 10MPa.
316 intsimbi engatyiwa:equlethe i-molybdenum element, enokumelana nokukhula okungcono kune-304, inokumelana namanzi olwandle, izisombululo zetyuwa ephantsi, i-sulfuric acid ehlanjululwayo, njl., ilungele indawo yaselwandle, i-media mediald corrosive, ubushushu ≤ 800 ℃.
310S intsimbi engatyiwa:ukumelana nobushushu obuphezulu (≤ 1200 ℃), ukuxhathisa okuqinileyo kwe-oxidation, ilungele iimeko zokufudumeza ezifana negesi yobushushu obuphezulu kunye netyuwa etyhidiweyo, kodwa ukuxhathisa okungaphantsi kancinane kwi-316.
Intsimbi yekhabhoni
Ixabiso eliphantsi, amandla omatshini aphezulu (anokumelana noxinzelelo> 20MPa), kodwa ethanda ukurusa (ifuna ipeyinti enqanda umhlwa okanye ukukhuselwa kwegalvanizing), ilungele kuphela into engonakalisiyo, ubushushu begumbi/ubushushu obuphakathi (≤ 300 ℃) kwimidiya, efana ne-oyile ye-injini yokufudumeza kunye neegesi eziqhelekileyo zeshishini.
3, Amanyathelo okukhetha kunye neereferensi zemeko
1. Cacisa iimfuno ezingundoqo:
Okokuqala misela i-medium (i-corrosiveness / cleanness), iqondo lokushisa (iqondo lokushisa kwegumbi / ukushisa okuphezulu), uxinzelelo (uxinzelelo oluphezulu / uxinzelelo oluphantsi?), kwaye emva koko udibanise iimpawu eziphathekayo.
2. Imizekelo yemeko eqhelekileyo:
Ukufudumeza amanzi ompompo / amanzi aqhelekileyo amashishini: i-304 insimbi engenasici (ixabiso lokulinganisa kunye nokumelana nokubola);
Ukufudumeza amanzi olwandle/amanzi amdaka aphantsi anetyuwa: 316 intsimbi engatyiwayo (emelana ne-chloride ion corrosion);
Ukufudumeza okugxininiswe kwi-hydrochloric acid / isisombululo se-alkali eyomeleleyo: i-titanium alloy okanye i-Hastelloy alloy (eneemfuno eziqinileyo zokuxhathisa ukubola);
Ibakala lokutya lokufudumeza kwamanzi ashushu: 316 intsimbi engatyiwayo (icocekile + i-corrosion-resistant);
Ubushushu obuphezulu berhasi yokufudumeza (800 ℃): 310S intsimbi engatyiwayo (imelana ne-oxidation yobushushu obuphezulu)
