Le nsimbi ine-nickel ephezulu kanye ne-chromium enikeza ukumelana nokuqina okuqhathaniswa, ukumelana ne-oxidation kanye nokugcinwa kwengxenyana enkulu yamandla okushisa asekamelweni anjenge-alloys evamile ye-auntenitic njengohlobo 304.

I-Monel 400 Alloy inezindawo eziningi ezinhle kakhulu zemishini, okwenza kwadume ngokufakwa kwamapayipha. Ama-monel 400 amapayipi ukufakwa kwamapayipi anganikeza ukusebenza okuphezulu. Kuyi-alloy ye-nickel ne-zethusi, ngenani elincane lensimbi, i-manganese, ikhabhoni kanye ne-silicon okuqukethwe. Ukwakheka kwamakhemikhali kwama-alloy 400 amapayipi okufakwayo kuphumela emandleni ayo aphezulu. Umkhiqizi okhethekile we-Monel Fittings e-India futhi ugxile ekukhiqizeni ikhwalithi ephezulu yalezi zinto ezifunwa ngepayipi ngenxa yokufunwa kwayo okuphezulu ezimbonini ezahlukahlukene- ama-alkali yisizathu esikhulu ngemuva kwalokho. I-alloy 400 buttweld elbow nayo ine-decticiled enhle, ukuqhutshwa okushisayo, futhi kungaqiniseka kuphela ngokusebenza okubandayo.

I-Welding of Incoloy 825 kumele yenziwe esimweni esivelele futhi ihlanzwe ngebhulashi lensimbi engenasici ukuze lisuse amabala, uthuli kanye nokumaka okuhlukahlukene. Lapho i-welding impande ye-weld, kufanele ithathwe kakhulu (i-argon 99.99) ukuthola ikhwalithi engcono kakhulu ye-root weld ukuze i-weld ayikhiqizi oxides ngemuva kwempande yelded. Umbala ovela endaweni ephazamiseka ukushisa okushisayo kufanele ususwe ngebhulashi lensimbi engenasici ngenkathi indawo ye-weld ayipholile.

Incoloy 800ht, eyaziwa nangokuthi ¡° alloy 800ht¡ ±, kukhethwe njenge-UN CIN N08811 noma Din W.nr. 1.4959. Kuyinto i-iron-nickel-chromium alloy enokwakheka okufanayo okuyisisekelo njenge-incoloy 800 ne-incoloy 800h kodwa ngamandla aphezulu kakhulu wokuqhuma kwamandla.

Lokhu kufanelekile kusetshenziswa ezinhlelweni zamapayipi ukushintsha ukuqondisa noma ukusebenza futhi kuxhunywe ngomshini ohlelweni. Indlela elula yokwenza lokhu ukugoba ipayipi endaweni oyifunayo, kepha le nqubo izokwelula futhi ibe mncane udonga lwangaphandle lwepayipi ngenkathi luqina futhi luphambana nodonga lwangaphakathi lwepayipi. Umugqa wethu wama-22055 wokufakelwa kwama-duplex ufaka ama-radius ama-radius ama-elbows amade kanye ne-radius radius elbows.

I-ASTM A234 iyindinganiso yezinto ezifanelekile ngepayipi. Kodwa-ke, lokhu kukhombisa izakhiwo zezinto ezibonakalayo zezinhlobo ezahlukahlukene zensimbi yensimbi ne-carbon. I-WPB yibanga lensimbi lapho w imele i-weldable, b i-grading b futhi p imele ingcindezi. Ngakho-ke idlulisela amandla asezingeni eliphansi.

Ukufakelwa okungu-321 kuhlanganisa indinganiso ye-auntenitic auntenitic acrenings ukufakwa kwezinsimbi kwezicelo zokucindezela kwamapayipi. Izinto zokufakelwa kwamaphayipha zizobandakanya ukujeziswa, imigoqo, amapuleti noma amapayipi angenamthungo noma anezinwele. Ukwakha noma ukwakha imisebenzi kuzokwenziwa ngesando, ukucindezela, ukubhoboza, ukukhiphela, ukuqeda, ukuqeda amandla, ukugoqa, ukugoqa ukuthuka, imishini, noma inhlanganisela yemisebenzi emibili noma ngaphezulu. Zonke izesekeli kufanele zithathwe ukushisa.

I-Monel 400 iyi-alloy ye-nickel-Copper (cishe ngo-67% NI ¨c 23% Cu) emelana namanzi asolwandle kanye nama-caustic solutions ezindaweni eziningi ze-acidic ne-alkaline ezifanelekile ngokunciphisa izimo. Ukuhlehlisa okuhle nokusebenza okushisayo okulungele izinhlelo zokusebenza zamanzi olwandle.

Ukuze izinhlelo zokusebenza ze-Pers Mill ezidinga amamaki aphansi angenawo ukumelana nokwanele. Kususelwa kokuqukethwe kwe-chromium engama-22%, bane-auntenitic ehlanganisiwe: i-fisscitic fickscucture enikeza amandla amakhulu, ukumelana nokugqwala kanye nokusebenza kwezindleko.

Ngaphezu kwezindawo ezingama-304, 316 zensimbi engagqwali kanye neziphetho ze-tube ziphelile zikhule ukumelana nokukhulisa ukubhujiswa ngenxa yokungezwa kwe-molybdenum ekubukeni kwabo. Kukhona ama-flanges e-duplex esifushane kanye nokufakelwa.

Kune-ASTM evamile kakhulu ye-ASTM A234 WPB Ellow isemfunweni ikakhulukazi, i-45¡Ã, 90¡Ã no-180¡Ã futhi 180¡Ã futhi 180¡Ã elbows, bobathathu kunguqulo "ende Radius" kanye no-180¡Ã no-180¡Ã no-180¡Ã futhi ngo-180¡Ã elbows zombili inguqulo "emfushane radius" version.

I-Alloy 400 inokumelana nokugqwala, amandla aphezulu kanye nokusheshisa okuhle. I-Monel 400 inezakhiwo ezinhle kakhulu zemishini emazingeni okushisa ayi-zero. Inendawo yokuncibilika ye-2370-2460¡ãf futhi isetshenziswa kalula emazingeni okushisa afinyelela ku-1000¡ãf.

Phakathi kwamabanga ahlukahlukene wensimbi engenasici, ibanga elilodwa yinsimbi ye-auntenitic equkethe i-columbium. Ukufakelwa okwenziwe kusuka kuyo kubizwa ngokuthi ukufakwa kwensimbi engagqwali 347. Zisetshenziswa kabanzi emazingeni okushisa aphezulu futhi zinekhwalithi emangalisayo ne-welding. Ukufakwa kweColumbium kuya kokufiphala kwensimbi engagqwali 347 Weld Kubonisa nokumelana okuthuthukile kokugqwala ezindaweni ezinamandla kakhulu. Kusetshenziswa kabanzi ukufaka, xhuma futhi kulungiselele eminye imikhiqizo.

Uma kuqhathaniswa ne-Chromium-Nickel Auuntenitic Steel engenasici, i-316l yensimbi engenasici inikeza ama-creep aphezulu, ukucindezelwa ukugqokwa kanye namandla ashubile emazingeni okushisa aphakeme.

Ukuze udlulise ipayipi, kuyadingeka ukususa i-hose eqondile epayipini. Lapho usebenzisa amapayipi ahlukahlukene, kufanele kusetshenziswe amapayipi ahlukahlukene. Lapho kusetshenziswa ipayipi, i-elbow kumele isetshenziselwe ukushintsha usayizi wepayipi. Lapho u-bifurcating, ipayipi elinezindlela ezintathu i-Flange uxhumano olusetshenzisiwe lapho i-joint isetshenziswa ama-pipeline ahlukahlukene amahle, ukuze ifinyelele ekukhuliseni okuhlangene noma ukugcwaliswa okuhlangene okuhlangene noma ukukhishwa okusebenzayo okubandayo kanye nokuhlangana okubandayo okuhlanganisiwe kusetshenziselwa ukuxhumana kwepayipi. , Ekuxhumaneni kwamathuluzi ahlukahlukene, kukhona nezixhumi nama-plugs esigaba sensimbi.

I-304 I-Ellow Engagqwali yensimbi iyinto efanelekile yepayipi exhuma amapayipi amabili nge-diameter efanayo noma ehlukile ohlelweni lwamapayipi, ukuze amapayipi agobeke engela ethile. Ngokusho kwe-angle, esetshenziswa kakhulu yi-45¡Ã, 90¡Ã, 180¡Ã. Ngaphezu kwalokho, ngokuya ngezidingo zobunjiniyela, ezinye izindolo ezingejwayelekile ezinjenge-60¡Ã nazo zifakiwe. Izindlela zokuxhumeka ngepayipi zifaka ukufudumeza okuqondile (indlela evame kakhulu), ukuxhumana kwe-flange, ukuxhumeka kwe-thraused, ukuxhumana kwesokhethi, njll.

I-Cuni 70 \ 3 ama-elbows anamandla amakhulu okubekezelela isivinini esiphakeme emanzini olwandle.

Lokhu kufanele kube yingxenye yohlelo lokuhambisa uketshezi (uwoyela, igesi, umusi, amakhemikhali, ...) ngendlela ephephile futhi ephumelelayo, amabanga amafushane noma amade.

I-Alloy 800h ingukushisa kwesixazululo okuphathwe (2100¡ÃÇf \ 150¡Ãc) Ithuthukise kangcono izici ze-creep ne-persert-strupture in the 1100¡Ãf (593¡Ãc) ku-1800¡Ãf (982¡Ãc) uhla lokushisa.

I-Butt Weld Pipe Fitting yenzelwe ukuthi ifakwe kwisayithi ezindaweni zayo (ama) ukuxhuma amapayipi (s) ndawonye futhi avumele ushintsho kububanzi obuhle noma ngepayipi, noma ephepheni noma ekuphelisweni.

Ukufakelwa kwama-contel 600 kwenziwa nge-nickel-chromium alloy equkethe ubuncane bama-72% nickel kanye ne-14% chromium ekwakhiweni ngekhabhoni, i-manganese, isibabule, ithusi nensimbi.

Ukuchithwa kwamapayipi we-N04400 butt Futhi kubhekiswe njenge-WNR 2.4360 Butt Weld Pipe Fittings, inezakhiwo ezinhle kakhulu zemishini ezivela kumazinga okushisa aphezulu afinyelela ku-1020¡oà f. I-Alloy 400 (ukuncishiswa kwe-eccentring) Ukufakwa kwamapayipi we-Weld, ukufakwa kwamapayipi we-butt welt weld, nokuningi.

Lezi zinto ezifakiwe do¡¯t deform noma dislociate kalula ezingcindezi eziphezulu kanye namazinga okushisa aphakeme. Ukufakwa kwama-alloy 600 kunamandla aphakeme kanye nezakhiwo ezinhle kakhulu zemishini. Banekhono elisezingeni eliphansi le-655mpa kanye namandla aphansi wesivuno angama-310 MPA.

I-ASTM A403 WPP310 \ 310s iyi-autenituric ukushisa okumelana nokuphika okunamandla okuphikisana ne-oxidation ngaphansi kwezimo ezi-2000.

I-Incol600 ilungele ukufudumala ngendwangu efanayo noma ezinye izinsimbi nganoma iyiphi inqubo ye-welding yendabuko, e-arc ye-arc i-welding, i-arc ye-arc ye-arc, i-arc ye-arc i-arc ishiziwe, futhi i-arc ye-arc ishiziwe. I-Welding yisisombululo esithandwayo. Lapho usebenzisa i-ARC WELDIT ye-ARC, kunconywa ukusebenzisa igesi evikelekile exutshwe nezakhi ezahlukahlukene (i-AR + he + H2 + CO2).

Ukuchithwa kwamapayipi we-N04400 butt Futhi kubhekiswe njenge-WNR 2.4360 Butt Weld Pipe Fittings, inezakhiwo ezinhle kakhulu zemishini ezivela kumazinga okushisa aphezulu afinyelela ku-1020¡oà f.

I-S31803 uhlelo lokufaka izinombolo oluhlanganisiwe (ama-UNS) lwensimbi yokuqala yensimbi engenacala. Uhlelo olungeyena lwakhiwa amaqembu amaningi okuhweba ngawo-1970s ukunciphisa ukudideka lapho i-alloy efanayo ibizwa ngezinto ezahlukene, futhi okuphambene nalokho. Insimbi ngayinye imelelwa yincwadi elandelwa izinombolo ezinhlanu, lapho incwadi imele uchungechunge lwensimbi, i.e. s ngensimbi engagqwali.
