Kwakhelwe ukuhlinzeka ngokumelana okuhlukile kokugqwayiza kuzo zombili izimo oxidizing kanye nokunciphisa izindawo.
I-A515 GR.70 isetshenziswa ekwakhiweni kwama-boilers aklanyelwe ukumelana nengcindezi yangaphakathi yemikhumbi yengcindezi, ama-boilers nama-valve.
Ngenxa yokuqukethwe okuphezulu kwe-chromium, la ma-carbon sten anokumelana kahle nokugqwala.
I-ASTM A516 CS 70 Ibanga lama-Flanges lisetshenziselwa izinhlelo ezahlukahlukene ezinjengamabhuloho, izakhiwo, izimoto zeloli, izimoto, ama-surcases, amapontshi, amapayipi elokwakha, amapayipi enhlaka kanye nezigxobo zamandla, njll.
Insimbi engu-316l ihlanganisa izakhiwo ezinhle kakhulu zemishini ngokukhononda okuhle ngolunye lwezinhlaka ezinhle kakhulu zamakhemikhali emndenini wensimbi.
Ngaphandle kwalokho, kukhona ezinye izehlakalo zebanga ezifana ne-F, N, H kanye nabanye abaningana, ngokulungisa ukucaciswa kwekhabhoni, i-mulfur, i-phromiro, i-chromium, i-molybdenum, nickel, njll. Ukuthola izakhiwo ezifunwayo.
I-316l yaziwa kakhulu phakathi kwabakhiqizi bokumelana nokuqhekeka ngemuva kokuthi inqubo yokufaka i-welding iphelele. Lokhu kwenza i-316L ukukhetha kokuqala kwabakhiqizi abafuna ukwakha izakhiwo zensimbi zezicelo zezimboni.
Empeleni kuyinsimbi evamile yekhabhoni futhi akumelani nokugqwala. Kuzogqwala ngaphandle kokuthi kuvikelwe. Ingagudluzwa kalula noma ibanda kakhulu njengensimbi ejwayelekile yekhabhoni.
Ukwenza insimbi kuqala ngokubhema kwensimbi ore, okususa ukungcola okufana ne-phosphorus, i-silica nesibabule.
I-A182 F316L i-Flange ekhethekile efanelekile yezicelo zesikhathi eside ezizobhekana nezinto
Lapho kudingeka i-welding, insimbi inempahla yokuqhekeka njengoba ipholisa. Amazinga okushisa aphezulu wenqubo yokufaka i-welding abangela lokho okwaziwa ngokuthi "ukufezekiswa okushisayo" njengopholile wensimbi. Lokhu kwenza izakhiwo zakhiwe ngensimbi ephezulu yokuqukethwe kwekhabhoni zithambekele ekulimaleni ngenxa yokwakhiwa kwemifantu ezindaweni lapho insimbi ifakwa khona insimbi. I-Alloy yensimbi engagqwali isetshenziswa ezinhlobonhlobo zezicelo njengoba ilungele kahle ukugwema ukugqwala kwe-weld. Futhi ingamelana namazinga okushisa aphezulu futhi inendawo ephezulu yokuncibilika cishe ngama-degrees Celdius acishe abe ngu-2,500 ama-degrees acishe abe ngu-1,370. Ngaphezu kwekhabhoni, le alloy iqukethe u-2% manganese futhi aze afike ku-0.75% salicon.
Okuqukethwe okuphansi kwekhabhoni ka-316L kunikeza isixazululo esisebenzayo senkinga evamile yobunjiniyela ngensimbi engama-316 yensimbi engagqwali. Lolu shintsho oluncane kuhlelo lwakho lokusebenza lungaba nomthelela omkhulu kwizindleko zakho zokusebenza kanye nemingcele yokuqinisekiswa kwekhwalithi njengenhlangano yebhizinisi. Ngokungafani nezinye izinhlobo zensimbi ezifana ne-304 no-306, i-altoy yensimbi engama-316l ingasetshenziswa ezinhlobonhlobo zezicelo lapho ukumelana nokugqwala okuphezulu kudingeka khona. Isibonelo, ochwepheshe kwizimboni zamakhemikhali nezemithi bayisebenzisa ukwenza amathuluzi okuhlinza kanye nezimpawu zokwelashwa.
Ishidi le-nickel alloy lisetshenziselwa izimboni ezinjengokulawulwa kokungcoliswa komoya, amakhemikhali kanye nama-petrochemical, ukucubungula ukudla, ukucubungula ama-petrolise, ukucwilisa uphethiloli kanye nokulahlwa kukadoti kanye nokulahlwa kukadoti.
Yize zombili lezi zinsimbi zithathwa njengezinhlamvu zensimbi ephansi yekhabhoni, zihlukile kakhulu. Isibonelo, "l" umele "ophansi" ngensimbi engama-316l, okusho ukuthi i-alloy inokuqukethwe okuphansi kakhulu kwekhabhoni. I-316l ehlukile futhi imelana nokugqwala okukodwa futhi ingamelana namazinga okushisa aphezulu kune-316. Yingakho i-316l ivame ukusetshenziswa kumaphrojekthi wasolwandle nezakhiwo.
I-Stainless, Duplex, Alloy ekhethekile, Info, Monel, Monel, Hastelloy, Nitronic & Carbon Insimbi - I-Zhengzhou Huitong Pipeline Equipment Co, Ltd.
I-ASTM 515 GR 70 iyi-carbon ephakathi nayo equkethe amanani athile ama-manganese, phosphorus, isibabule kanye ne-silcon.
Ngefomu le-ore, ukugcwala kwekhabhoni kudlula izinga elidingekayo kwizakhiwo ezihlukile zensimbi. Ngakho-ke, abenzi bensimbi baphindisele insimbi encibilikisiwe ukuze banciphise okuqukethwe kwekhabhoni kunani elifunekayo.
Ama-alloys afana ne-monel 400 flanges enza kahle ezindaweni zasolwandle ngenxa yokwakheka kwamakhemikhali. Okuqukethwe yi-Copper kuphakathi kuka-28% no-34% futhi kwaziwa njenge-superelloy ngenxa yokumelana nakho kokugqwala okuhle.
Uhlobo lwensimbi engu-316 lungenziwa kwelinye ibanga ngenxa yobubanzi bawo obukhulu obunamandla futhi buhlukaniswe ukusetshenziswa kwencwadi "l" egameni layo. L imele okuqukethwe okuphansi kwekhabhoni ngensimbi.
Izicelo ezijwayelekile zensimbi zifaka: Imishini yokulungiselela ukudla, imishini yelebhu, iziqukathi zamakhemikhali zokuhamba, iziphethu, izikrini zokushisa, izitifiketi zokugula, ukugcwaliswa kwasolwandle, ukugcwaliswa kwamanzi. Omunye womehluko omkhulu phakathi kwensimbi engama-316l yensimbi engenacala nensimbi engama-316 eyenziwe ngeziqhingi ukuthi okuqukethwe yi-carbon kwangaphambili kuphakama ngo-0,03%, kanye nokuqukethwe kwekhabhoni okugcina kuphakeme njenge-0.08%. Lo mehluko ubanikeza izakhiwo ezahlukahlukene. Masifunde kabanzi nge-alsoy yensimbi engama-316l engenasici.
Ukulandela umkhondo wezimpawu ezihlukanisayo zensimbi, abakhiqizi badale uhlelo lokuqamba oluhlelekile nokwenza okuphelele.
Ezinye izinto zingangezwa kwisakhiwo esishisayo se-Iron Ore ukukhiqiza izinhlobo ezahlukene zensimbi. Uhlobo ngalunye lwensimbi lungasetshenziselwa izinhlelo ezithile zemboni ezisukela ekwakhiweni ukuze ziqiniswe ukwakheka.
Ngoba i-alloy kulula ukuyisebenzisa futhi ithambekele ekulimaleni, izinkampani zigoba ngezimo namafomu ahlukahlukene. Isibonelo, insimbi engagqwali engama-316l iyatholakala ku-strip, ucingo, ishidi, ibha kanye nezinye izimo. Yonke imboni ihlise ngempumelelo le nsimbi ukudala imikhiqizo ehlukahlukene eqediwe.
I-A515 Ibanga lama-70 Carbon Carbon lingafakwa emikhunjini yokucindezela ukuze uthole insiza yokushisa ephezulu. Imishini yayo ilungile, ifana nensimbi evamile yekhabhoni.
Isetshenziselwa ikakhulukazi imithambo yengcindezi ye-welded lapho kudingeka khona ubunzima be-notch.
Thayipha insimbi engamakhemikhali engamakhemikhali nangokwemishini efana nebanga lamabanga angama-316.
I-A182 F316L Flange ekhethekile kuzinhlelo zokusebenza ezibeka engcupheni yokuchayeka kwe-chloride
Alloy 825 (uns n08825) yi-auntenitic nickel-iron-chromium alloy enokwengezwa kwe-molybdenum, ithusi ne-titanium.
Lawa ma-ASTM A516 Carbon Ibanga lama-60 Flanges atholakala ngesitifiketi sefekthri e-EN10204 3.1 noma EN10204 3.2. Ama-Flanges ethu alandelwa ngokuphelele, imvamisa enezitembu ezinzima, futhi sigqugquzela noma yimuphi umuntu wesithathu noma ukuhlolwa kwamakhasimende.
I-ASTM A515 Ibanga lama-70 Carbon Insimbi lisetshenziswa ezitshalweni ze-boiler zamakhemikhali nakumboni we-petrochemical. Kuyamelana ngisho nasekushiseni okuphezulu emkhakheni wohlelo lokusebenza.
