Intsimbi engenasitali inokufunyanwa kuyo yonke indawo ebomini, kwaye zonke iintlobo zeemodeli ezisisidenge ukwahlulahlula. Namhlanje ukwaba nenqaku lokucacisa amanqaku olulwazi apha.
Intsimbi engenasimo sisifinyezo sensimbi enganyangekiyo ye-acid, umoya, isitya, amanzi kunye nezinye iintsimbi ezingenantlonelo okanye intsimbi engenazibala; kwaye iya kuba yinyameko kwimithombo yeendaba zekhemikhali (Acids, ialkalis, iityuwa, kunye nenye i-station yokungena kunye nentsimbi ebizwa ngokuba yintsimbi ye-Acid-i-Acid-i-Acid-i-Acid-i-Acid-i-Acid-i-Acid-i-Acid-i-Acid-Portiver -untrant ebizwa ngokuba yintsimbi ye-Acid.
Intsimbi engenasitali ibhekisa kumoya, i-steam, amanzi kunye nezinye iindaba ezibuthathaka zobuthathaka kunye ne-acids, ialkalis, i-ialkalis, iityuwa kunye nentsimbi engaqhelekanga ye-acid. Xa uziqhelanisa, amaxesha amaninzi abuthathaka kwimidiya yosasazo ye-corrosion yosasazo enokuyichaphazela intsimbi engenasitayile, kunye ne-scoresion yensimi ye-comrosion ye-corrosion yokungakwazi ukuchasana nentsimbi ebizwa ngokuba yintsimbi ye-Acid. Ngenxa yomehluko ekubunjweni kwamachiza kwezi zimbini, eyangaphambili ayinyanzelekanga ukuba inganyangeki ekubonakalisweni kweendaba zekhemidimikhali, ngelixa le nto ibaluleke kakhulu. Ukuchasana ne-corrosion yensimbi engenanto kuxhomekeke kwizinto ezabelweyo ezikwintsimbi.
Ukwahlulahlula
Ngokutsho kombutho we-metricjeal
Ngokubanzi, ngokombutho weqonga, izitho eziqhelekileyo ezinamandla zahlulwe zangamacandelo amathathu: i-Austititic Staiels, i-Ferrictic Staiels kunye neMartiaticic Steiels. Kwisiseko soMbutho weMetrolical osisiseko kwezi ndidithu, ii-Deppex Speels, ukulinganisa ukwenza izinto ezingenasitali kunye nezibetho eziphezulu ezinama-50% i-iron yentsimbi ethathwe kwiimfuno neenjongo ezithile.
I-1. Intsimbi engathandekiyo
Imatrix ukuya kwi-Crystic egxile kwi-cubictal ye-cubictal ye-austeriting yombutho (iSigaba seCY) ilawulwa yi-agnetic, ikakhulu ngokusebenza kwe-magnetism) yentsimbi engenasiseko. I-American Iron kunye ne-Iron Institute i-200 kunye ne-300 yeelebheli ezingama-300, ezinjengama-304.
I-2. Intsimbi engenasitayile
I-Matrix ukuya kwi-Crystal egqwesileyo ye-cuic ye-frielic yombutho (isigaba) inamandla, i-magnetic, ngokubanzi ayinakukhumbula unyango, kodwa ukusebenza kubanda kungayenza iqinile intsimbi engenasinga. I-American yentsimbi kunye nentsimbi yentsimbi ukuya kwi-430 nelama-446 kwileyibhile.
I-3. Martianiticic Stainess
I-Matrix yintlangano yeMartixic (i-cubic egqwesileyo okanye i-cubic), i-magnetic), i-magnetic, ngonyango lobushushu linokuhlengahlengisa iipropathi zayo ezingenamatshini. I-American yentsimbi kunye ne-Iron Institute ukuya kwi-410, 420, kunye nama-440 amagqabantshintshi aphawulwe. UMartines unentlangano ye-austentitic kwiqondo lobushushu eliphakamileyo, elinokuguqulwa ukuba i-marterite (okt ilukhuni) xa ipholile kubushushu begumbi ngenqanaba elifanelekileyo.
I-4. I-Austeritic i-ferrite (i-duppex) yohlobo lwentsimbi engenasitali
IMatrix inomanyano lwesigaba kunye ne-Ferrite Triteritic kunye ne-Ferrite Tripter, yomxholo we-matrix ye-anser inkulu kune-15%, i-magnetic, inokusomelezwa kukubanda isebenza ngentsimbi engenasitayile. Xa kuthelekiswa nentsimbi engenasitayile engenasitayile, i-Dulplex yentsimbi ephakamileyo, ukumelana ne-Countrasion Sormosion kunye ne-chloride uxinzelelo loxinzelelo kunye nokuthambisa kuphuculwa kakhulu.
I-5. Ukunyanzeliswa kwentsimbi engenasitali
IMatrix ingumbutho okanye uMartiatic, kwaye unokulukhuni ngokwenza lukhuni unyango lokwenza ukuba lukhuni intsimbi engenasigaba. I-American yentsimbi kunye ne-Iron Institute ukuya kwiilebheli ezingama-600 zeelebheli zedijithali, ezinje nge-630, oko kukuthi, 17- 17ph.
Ngokubanzi, ukongeza kuma-Alloys, ukuxhathisa i-corrosion yentsimbi engenasiseko i-austenitic iphezulu, kwimeko enobunkunkqele, ukuba i-ferritive yendawo engathandekiyo, unokusebenzisa i-stailitive yentsimbi, ukuba unokusebenzisa intsimbi engenasitayile kunye ne-martians.
Iimpawu kunye nokusetyenziswa
Inkqubo yomphezulu
Ubukhulu becala
1. Kuba oomatshini bokuzima kwentsimbi kwinkqubo eqengqelekayo, iirowu zishushu ngokusebenza kancinci, okukhokelela ekuqhubeni ipleyiti ubuqhetseba, ngokubanzi embindini wamacala amabini amabini amatye. Ukulinganisa ubukhulu beMigaqo yeLizwe lePleti kufuneka ilinganiswe embindini wentloko yeplate.
2. Isizathu sokunyamezelana kusekwe kwimarike kunye nemfuno yabathengi, ngokubanzi yahlulwahlulwa yangamanyala amakhulu.
V. Imveliso, iimfuno zokuhlola
I-1. Iplate yombhobho
① I-Tube ye-tube ye-tube ye-tube ye-tube ye-tube ye-rute ye-100% yokuhlola i-ray, inqanaba elifanelekileyo: RT: ⅱ UT: ⅰ Inqanaba;
② Ukongeza kwintsimbi engenasitali, i-Piped Pipe Doul Preser Hible yonyango;
③ I-Tube ye-tube ye-puble ye-bridge phaidge: Ngokwefom yefomula yokubala ububanzi bebhulorho yeHool Bridge: B = (D) - D1
Ubuncinci bobubanzi be-HALEBIDGE: B = 1/2 (S - D) + C) + c;
I-2. I-Tube Box
I-Carbon Steel, i-alloy ye-alloy ye-waldy ye-weldare yokwahlulahlula ibhokisi yombhobho, kunye nokusetyenziswa kwe-pump yebhokisi ye-pumeral, ekusebenziseni i-Deding Sures, kwi-Flange kunye neSahlulo lokwahlula-hamba emva konyango lwetywina.
3. Uvavanyo loxinzelelo
Xa inkqubo ye-Shell yoyilo iphantsi koxinzelelo lungaphantsi koxinzelelo lwe-tube, ukuze kuhlolwe umgangatho wobushushu ityhubhu ye-tube kunye ne-tube ye-tube
I-Shell yenkqubo ye-Shell ye-Shell yonyusa uxinzelelo lovavanyo ngenkqubo ye-pipe ihambelana novavanyo lwe-hydraulic, ukujonga ukuba ngaba ukuvuza kombhobho. (Nangona kunjalo, kuyimfuneko ukuqinisekisa ukuba uxinzelelo lwefilim yeqokobhe ngexesha lovavanyo lwe-hydraulic yi-Hydraulic ≤0.9relφ)
Xa le ndlela ingentla ayilunganga, iqokobhe linokuba luvavanyo lwe-hydrostatic ngokwengcinezelo yoqobo emva kokudlula, kwaye ke iqokobhe lovavanyo lwe-Ammonia lokuvuza okanye i-halogn lokuphumeza.
Luhlobo luni lwentsimbi engenasiseko akukho lula?
Zintathu izinto eziphambili ezichaphazela ukutyhoboza kwentsimbi engenasimo:
1.Umxholo wezinto zokwabelana. Ngokubanzi, umxholo we-chromium kwi-10,5% yentsimbi akukho lula ukungcungcutheka. Ukuphakama komxholo weChromium kunye ne-Nickel Corrosion ilunge ngakumbi, njengo-304 umxholo we-85 ~ 10%, umxholo we-18%, i-chromium ye-18%, intsimbi engenasimo ngokubanzi ayikho ruel.
2. Inkqubo yokunyibilikisa yomenzi iya kuchaphazela inyathelo lokunganyangeki kwentsimbi engenasigaba. Itekhnoloji yokunyibilika ilungile, izixhobo eziphezulu, itekhnoloji enkulu, isityalo esikhulu esingaqhelekanga solawulo lwezinto zokwabelana, ukususwa kobushushu be-billet kuya kufuneka kuqinisekisiwe, ngokomgangatho wobushushu obuqinisekileyo, akukho lula ukungqubana. Ngokuchasene noko, ezinye izityalo ezincinci zentsimbi zibuyela umva, itekhnoloji engasemva, inkqubo yokunyibilika, ukungcola akunakususwa, ukuveliswa kweemveliso kuya kuba yintsika engathandekiyo.
I-3. Indawo yangaphandle. Indawo eyomileyo nenomoya ayilula ukuba irhuqa, ngelixa i-suidity yomoya, imozulu eqhubekayo eqhubekayo, okanye umoya oqulathe i-acidity kunye no-alkality yendalo kulula ukurhuqa. I-304 intsimbi engenasiphelo, ukuba indawo engqongileyo ihlwempu kakhulu kakhulu nayo ikwangusohlwayo.
Ibala lentsimbi engenasitali linjani?
1. Indlela ye-1.IC
Ngokukhetha i-paste okanye ukutshiza ukuze kuncede amalungu ayo athobileyo ukuba anyanzelise ukwenziwa kwefilimu ye-chromium oxidileyo, emva kokuyisusa, kubaluleke kakhulu ukwenza ukuba kufike amanzi afanelekileyo ngamanzi. Emva kokuba yonke into iqhubekile kwaye iphinde iphindwe ngesixhobo sokuphumeza, inokuvalwa nge-poling wax. Kuba amabala asekuhlaleni asekuhlaleni anokusetyenziswa 1: 1 ipetrol, umxube weoyile kunye nerag ecocekileyo ukuze ucime amabala arhabayo.
I-2. Iindlela zoomatshini
Ukucoca i-Santibal, ukucoca ngeglasi okanye i-ceramic amasuntswana avuthayo, ukubhabha, ukuxubha kunye nokushicilela. Iindlela zoomatshini zinokubakho ukusula ungcoliseko olubangelwa zizixhobo ezazikhutshiwe, izixhobo zokuphumeza okanye izixhobo ezikhutshiweyo. Zonke iintlobo zongcoliseko, ngakumbi amasuntswana e-Iron yamanye amazwe anokuba ngumthombo wokukhula, ngakumbi kwiindawo ezinomswakama. Ke ngoko, ukucocwa kobuchwephesha ekucocekeni kufanele ukuba kucocwe ngokusesikweni phantsi kweemeko ezomileyo. Ukusetyenziswa kweendlela zoomatshini zicoca kuphela umphezulu kuphela kwaye azitshintshi ukuxhathisa i-corosion yezinto ezenziwayo. Ke ngoko, kuyacetyiswa ukuba iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde ibe nezixhobo zokuposa kwaye ivale nge-wingling wax emva kokucoca umatshini.
