Amalungu ensimbi engenasicizisetyenziswa ikakhulu ukudibanisa imibhobho eyahlukeneyo kwimibhobho.Ngophuhliso olukhawulezayo lokwakhiwa koqoqosho lwezihlanganisi zensimbi ezingenasici, izixhobo zensimbi ezingenasici zisetyenziswe ngokubanzi.Ngokuhlalutya ukuxhatshazwa kwe-corrosion layer ye-passivation ebusweni bensimbi engenasici, edityaniswe nokusetyenziswa kweteknoloji yemveliso ephezulu kunye nezixhobo, imveliso ihlangabezana neemfuno zemveliso kunye nobomi.Izixhobo ezikumgangatho ophezulu zensimbi ezingenasici zigcwalisa isithuba sasekhaya.
Izifakelo zentsimbi engenasiciluhlobo lwetyhubhu.Yenziwe ngensimbi engenasici, ngoko ibizwa ngokuba yimibhobho yensimbi engenasici.Kubandakanywa: ingqiniba yentsimbi, intsimbi yentsimbi, umnqamlezo wentsimbi, isinciphisi sentsimbi, ikepusi yentsimbi, njl njl. izixhobo zemibhobho yensimbi engenasici ngokwendlela yokudibanisa.I-elbows yensimbi engenasici isetyenziselwa ukugoba kombhobho;iiflange zisetyenziselwa ukudibanisa inxalenye yepayipi kwaye idibanise ekupheleni kombhobho.Ukudityaniswa kwemibhobho emithathu kwamkela umbhobho weti yentsimbi;ukudityaniswa kwemibhobho emine kwamkela umbhobho weti yentsimbi;umbhobho wokunciphisa insimbi engenasici isetyenziselwa ukudibanisa imibhobho emibini yobubanzi obuhlukeneyo.
Izihlanganisi zensimbi ezingenasici zisetyenziswe ngokubanzi kwiinkalo ezahlukeneyo zokwakha uqoqosho lwesizwe, ezifana namayeza, ukutya, ibhiya, amanzi okusela, i-biotechnology, ishishini lemichiza, ukuhlanjululwa komoya, ukuhamba ngeenqwelomoya, ishishini lenyukliya, njl. ubomi.
Izixhobo zensimbi ezingenasici zineenzuzo ezinkulu malunga nokumelana nokubola.I-petrochemical, i-aerospace, kunye nemizi-mveliso yamandla enyukliya iyacetyiswa ngakumbi ukuba isebenzise intsimbi engatyiwa.
1. Kutheni intsimbi engagqwali ingavuthi?
Undoqo wensimbi engagqwali engagqwaliyo kukuba xa insimbi engenasici ibonakaliswe kwigesi, ifilimu ye-passivation yenziwa ngokukhawuleza kumphezulu, ngaloo ndlela ikhusela i-oxidation eyongezelelweyo.Le filimu ye-passivation inokumelana ne-asidi eqinile.Ukumelana nokubola.Kodwa iyagqwala kwiindawo ezithile ezikhethekileyo, ezinje: indawo efumileyo kunye nenkungu yolwandle enetyuwa.
2. Malunga nama-304, 316, 316L
I-304 insimbi engenasici yinto eqhelekileyo eyaziwayo kwishishini njenge-18/8 yensimbi engenasici.Ineempawu zokwenziwa komsebenzi olungileyo kunye nokuqina okuqinileyo, kwaye ngokuqhelekileyo ifanelekile kwimizi-mveliso kunye neendawo zokuhombisa ifenitshala.
Umxholo wekhabhoni we-316 mkhulu kune-0.08%, kwaye amandla e-316 ngokuqhelekileyo angaphezulu kancinane kunezinto ze-316L.Ngokubanzi, izinto ezingama-316 zisetyenziselwa ukuhlangana kwe-ferrule.
I-316L inomxholo omkhulu wekhabhoni we-0.03% kwaye inokumelana nokugqwala okungcono.Kucetyiswa ukuba usebenzise i-316L kwizinto zemveliso ekufuneka zidityaniswe.
3. Imbonakalo
Xa kuthelekiswa namalungu entsimbi yekhabhoni, iintsimbi zetsimbi ezomeleleyo zinokugutyungelwa kwaye zikhazimliswe ukuze zibonakale ziqaqambile, zikhazimle, kodwa intsimbi yekhabhoni idinga ukugqunywa ngokukhawuleza ngengubo ecacileyo okanye ipeyinti emva kokupolisha, kungenjalo intsimbi yekhabhoni iya kuthi ekugqibeleni iphulukane nokubengezela kwayo kwaye ekugqibeleni ibe nomhlwa. , Intsimbi engatyiwayo ayiyomfuneko.
