I-Alloty 904l isebenza ngaphandle kwezinye izifuba ezingenanto ezingenanto ngenxa yenqanaba eliphezulu lokulwa kwe-nickel kunye ne-molybdenum.
Xa ukhetha iziqu ezingenazimpawu ezimele ukunyamezela iindawo ezinomhlaba, ii-austitotic stails zihlala zisetyenziswa.
Intsimbi engama-304 ingenalo ingenayo ubuthathaka obuthile: Ithathwa kukungabikho kwesisombululo se-chloride okanye imeko ye-saline efana nonxweme.
Imibhobho ye-SS enemibhobho yombhobho, i-Zhengzhou Huiitong Izixhobo zePipoliel I-Co., i-LTD
Ukuhanjiswa kwamanzi kunye neegesi ezinokutsha, imibhobho yentsimbi yeyona mibhobho iluncedo. Zisetyenziswa kumakhaya amaninzi kunye namashishini ukuze adlulisele igesi yendalo okanye ipetrone. Baye basebenzisa neenkqubo zomlilo ezivutha umlilo ngenxa yokumelana nobushushu bazo.
Ukuqina kwentsimbi yenye yezona zibonelelo zintle zenkqubo yemibhobho. Yomelele kwaye inokumelana neengcinezelo, amaqondo obushushu, othukayo, kunye nokuhlambela. Ikwanokuguquguquka okwahlukileyo okubonelela ngolwandiso olulula.
I-Alloty inolwazi oluhle lwe-oxidation kunye namandla e-cerp ukuya kwi-1500¡in (816¡cn). Ikwanolwazi lobushushu obuphantsi.
Intsimbi engama-316 ingenasinqwazi sinekhabhoni engaphezulu kwe-316l. Oku kulula ukukhumbula, njengoko i-L ime "iphantsi."
I-904l Austitic austenitic yentsimbi yentsimbi
Inani eliphezulu le-nickel kunye neChromium kwi-austentinitic stails ezingenazimpawu zinika iipropathi ezibalaseleyo, kunye nokunganyangeki kwengqondo.
Imibhobho yentsimbi engenasimo ingama-304 ngeflethi
I-ASTM i-A303 spools, i-SS ye-SS, i-Staine Spools, iBanga le-WP ye-SS ezingama-304, din2617 i-SS ye-SS ye-SS e-China.
Ezi ntsumali zengcali zivelisa inkqubo phantsi kweseti echaziweyo yomgangatho kunye nokuchaneka ukufumana ilungelo elifanelekileyo kwindawo nokugcina iipropathi ezifanelekileyo zobugcisa ezichazwe ngumthengi.
I-Stools yentsimbi yentsimbi ithunyelwa njengezinto ezakhe zaphakama zenkqubo yokufaka imibhobho, iflethi kunye nezixhobo zombhobho, kwaye zikhuliswe ngexesha lokwenza.
I-Prools ye-Pipe ifakwe kwangaphambili ukuba ihlanganiseke kube lula ukusebenzisa i-hoists, i-gaugus kunye nezinye izixhobo zokujoyina iinxalenye. Imibhobho ye-pubile idibanisa imibhobho emide eneeflethi ukusuka esiphelweni semibhobho emide ukuze ibonakaliswe kunye kunye neflethi ehambelana nayo.
I-316l ikwayintsimbi enkulu engaqhelekanga yobushushu obuphezulu, ukusetyenziswa okuphezulu kwe-corrosion, yiyo loo nto ithandwa kakhulu ngokusetyenziswa kwiiprojekthi zokwakha nezaselwandle.
Owona manqanaba mabini axhaphakileyo angama-304 nowama-316. Umahluko ophambili kukudibanisa i-molybdenum, isabelo esiphucula kakhulu ukunganyangeki kwetyiwa, ngakumbi ekubonakaliseni ityiwa.
Umxholo weChromium oPhakamileyo ukhuthazo kwaye ugcine ifilimu ekhusela umbandela kwiindawo ezininzi zoncedo.
Intsimbi engenasitali 904l \ / 1.4539 Izixhobo ezinokusetyenziswa ukwenza iphepha elishushu neliqengqelekayo, iimveliso ezigqityiweyo, ezigqityiweyo, kunye nemibhobho ye-weldied yezicelo zoxinzelelo.
Inokuchasana ngokugqwesileyo kwi-insosion engaphakathi emva kokuba ibonakalise amaqondo obushushu kwi-chromium ye-chromium ye-chromium ye-chromium ye-chromium ye-800 ¨C 1500 NORTNF (427 ¨c 816¡c).?
Iinxalenye ezihlanganisiweyo ziphathwa ngenjongo zokunciphisa uxinzelelo lwangaphakathi. Inkqubo yonyango lobushushu yenziwe ngokwemigangatho ye-ASTE B3.3. Emva koko, i-spools ye-pumele kufuneka ipeyintwe ngokukhusela umphezulu ovela kuwo nawuphi na umngcipheko wokungabikho.
Intsimbi engama-304 yeyona ndlela ixhaphakileyo yentsimbi engenasimo ehlabathini ngenxa yokunganyangeki kunye nexabiso. Ine-16% ukuya kwi-24% chromium ukuya kuthi ga kwi-35% i-nickel, kunye nexabiso elincinci lekhabhoni neManganese.
I-904l Ibanga elingafaniyo alifani nelinye intsimbi. Ngenxa yezixa zayo ezongezelelweyo zeChromium, iMolybdenum, i-nickel kunye nobhedu, i-904l yensimbi yokunganyangeki okuphezulu kwi-corrosion, i-rumps kunye ne-acids.
Ukongezwa kobhedu kweli nqanaba kunika ukumelana nokunganyangeki ngakumbi kunezifundo eziqhelekileyo zeChromium-Nikel Stail, ngakumbi ngokuchasene ne-sulfuric, phosphoric kunye ne-acetic acids. Nangona kunjalo, ukusetyenziswa kwe-hydrochloric acid ilinganiselwe.
Iifestile zombhobho ziinxalenye zangaphambi kokwakha inkqubo yenkqubo yokufaka. Imibhobho, iflethi, kunye nezixhobo zibizwa ngokuba zibizwa ngokuba zii-Pipe Spools kwaye ziveliswa ngaphambi kokuba zisetyenziswe kwinkqubo yokufaka.
Imiphetho yomphezulu yamacandelo kufuneka ibe nokungcola okungaphezulu kufuneka isuswe. Inkqubo yokuqiqa iphunyezwa kwimiphetho yamacandelo. Umatshini wokugaya uqashwe inkqubo yokuqubuka. Uhlobo loomatshini bokugaya ngokuthatyathwa kwenkanuko yahluka ngokwamacandelo entsimbi engenasitayile kunye nezinto ze-carbon.
I-Alloy 347 (ayingase-S34700) yi-Columbium ichithe i-austenitic plates yensimbi kunye nokunganyangeki kweyona meko inamandla kwi-321 (i-S32100).
Isikizi sePlasma Arc sisetyenziselwa imibhobho emikhulu (ngaphezulu kwe-Intshi ezingama-28 yobukhulu beepayipi zepayipi) kwaye ukusetyenziswa kwayo kukoyingenelo kumasebe. Ukuba kunokwenzeka, icala langaphakathi kufuneka ibekwe kwimibhobho okanye imibhobho, ukuze ikhusele kwizinto ezenziwe yi-Spatter edalwe yi-PROC ARC. Emva kokuba ukusikwa, kunye nokulungiselela umda kufuneka kugcinwe.
Inkqubo efanelekileyo yokuqina kunye ne-welding kufuneka isetyenziswe emva kokugqitywa kwamalungu. Ke ngoko, ngenxa yentsimbi engenasinqwizi kunye ne-carbon swipe spools, iinxalenye zinokuhlala kwiziseko zensimbi okanye iziseko zeplanga. Ngapha koko, nakuphi na ukunxibelelana phakathi kwekhabhoni ye-carbon kunye nentsimbi engenazinto kufuneka kuncitshiswe.
Inani le-wels kwi-spool kufuneka igcinwe kwindawo encinci. Ubungakanani besithuba esiphakathi kwe-Weltisontial Wels kunye nemigca emininzi ayifanele ibe nkulu kunexesha lane odongeni lombhobho okanye ofanelekileyo. Emva kwe-welds ephambili, iityhubhu ze-idlings kufuneka zenziwe ngokuchanekileyo. Zonke ii-wels kwi-spools kufuneka ziphunyezwe ngokwemigaqo efanelekileyo ye-welding (WPS). Emva kwenkqubo ye-welding yenziwa, ukulawulwa komgangatho wezinto kwenziwa ziingcali.
