Ukufakwa kwamapayipi wensimbi

I-800H ingamelana nokugqwala kwemidiya eminingi eqinile. Okuqukethwe kwalo okuphezulu kwe-nickel kwenza ukuthi imelane nokugqwala kokugqwala kokuqhekeka ezimweni zokugqwala ezinamanzi. Okuqukethwe okuphezulu kwe-chromium kunikeza ukumelana okungcono ekuqhekekeni ngokukhonkotha kanye nokuqhekeka kwe-crevice. I-alloy inokumelana kahle nokugqwala kwe-nitric acid kanye nama-organic acid, kepha ukumelana okulinganiselwe kwe-sulfuric acid ne-hydrochloric acid. Ukumelana nokugqwala okuhle ku-oxidizing kanye nosawoti ongasho lutho, ngaphezu kwamandla okugqwala okukhonkotha kuma-halides. Iphinde ibe nokuphikiswa okuhle kokugqwala emanzini, umusi kanye nokuxutshwa komusi, umoya kanye nekhabhoni diok dioxide.

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.

Ukubuyisa ukumelana nokugqwayiza okungokwemvelo kokusakazwa kwensimbi engenasici. Ukumelana nokugqwala kwensimbi engenasici kuncipha ngemuva kokuphonswa kwezimali. Ukumelana nokugqwala kokuncishiswa kwensimbi engenasici kutholakale ku-statemus enhle ngemuva kokwelashwa kwesisombululo.

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.

1.4529 Ikhodi Yezinombolo ZaseJalimane. Insimbi embi kakhulu ye-Super Dumplex, izakhi eziphambili: 20cr-25ni-6mo-1cu-0,2N ezihambelana ne-United States: N08926, 254smo ...
1.4529 (uns N08926) Unokumelana okuphezulu kakhulu ekugcekeni okukhohlisayo kanye nokugqwala kwama-crevice emithonjeni yezemithombo ye-halide nasezindaweni ezinama-acidic aqukethe isibabulfur ne-hydrogen
Kungamelana ngempumelelo nokugqwayiza kwe-chloride ion ukuqina, futhi kubuye kube nokumelana kahle nokugqwala nokuqina okuhle ku-oxidizing kanye nokunciphisa imidiya.
Izakhiwo zemishini zingcono kancane kune-904L, futhi zingasetshenziswa ekwenziweni kwemikhumbi yengcindezi kusuka ku--196 kuya ku-400 ¡Ãc.

I-Alloy 20 (Alloy 20) iyinhlangano ye-autenquitic esekwe ngensimbi eyenzelwe ukumelana nokugqwala kwe-sulfuric acid. Inokumelana okuhle kakhulu kwe-sulfuric acid corrision; Inokumelana okuqinile kwe-phosphoric acid, i-nitric acid kanye ne-chloride ezindaweni, ukugqwala okucindezela kwe-chloride, ukugqwala okukhonkotha kanye nokugqwala kwe-crack. Ngakho-ke, Alloy 20 unegama le-anti-corriosion alloy; Inezinhlobonhlobo zezicelo: njenge: Chemical, ukudla, umuthi, ukukhiqizwa kwamandla kanye nezimboni zepulasitiki kuzoyisebenzisa. Ukuze ukumelana nokugqwala okukhonkotha kanye nokugqwala kwe-chloride, izinkinga zokugqwayiza kwengcindezelo, njll., Alloy 20 kuvame ukusetshenziswa.

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.
Ukufakwa kwamapayipi wensimbi kuyindlela ejwayelekile yezakhi ohlelweni lwamapayipi odlala izindima zokuxhumana, ukulawula, ukuguqulwa kokuqondisa, ukuphambukiswa, ukubekwa uphawu kanye nokusekelwa. Umsebenzi: Ukuxhumeka, ukuguqulwa kwenkomba, ukubekeka, ukubekwa uphawu, ukusekelwa, njll. Ukufakwa kwamapayipi kusetshenziswa kabanzi ku-Petroleum, amakhemikhali, ama-Metallurgy, amandla kagesi kanye nezinye izimboni, futhi yizinto eziphambili zokwakhiwa kwezimboni. ^ - Zhengzhou Huitong Pipeline Equipment Co, Ltd.

Iningi lezinsimbi ezisekelwe kwinsimbi zisabela ngamanzi ukukhiqiza i-iron oxide ebomvu eyaziwa kangcono njengokugqwala. Ama-athomu omoya-mpilo emanzini adonsela insimbi yensimbi eyisisekelo ukwakha isakhiwo sokugqwala esinamandla ngaphandle kwamandla angempela.

I-ASTM A105 (eyaziwa nangokuthi i-ASME SA 105) ihlanganisa izakhi ze-carbon ezingenamthungo ze-carbon zensimbi ebekwe ekusetshenzisweni kwezinhlelo zokucindezela ku-ambient kanye nensizakalo ephezulu yokushisa.

I-nickel ibaluleke kangangokuba amamaki aqukethe ama-nickel akha ama-75% wokukhiqizwa kwensimbi engagqwali. Ukwaziwa kakhulu kwalokhu kunguhlobo lwe-304, olune-8% nickel kanye nohlobo lwe-316, olune-11%.

I-ASTM A105 I-Carbon Carbon ingakhiwa emazingeni okushisa alona angu-2200 kuya ku-1700 F alandelwa ngokucimana nokuguga noma okujwayelekile.

Lokhu okucacisiwe kuhlanganisa amazinga wezakhi ze-carbon zensimbi ye-carbon, okungukuthi, ama-flanges, ukufakwa, ama-valve, kanye nezingxenye ezifanayo, ukuze zisetshenziswe ezinhlelweni zokucindezela ezimeni eziphakeme nezimo eziphakeme zokushisa.

I-A105 izothathwa ukwelashwa okushisa (ukunqwabelana, okujwayelekile, ukufutheka, noma ukucima). I-A105 izovumelana nekhabhoni, i-manganese, phosphorus, isibabule, i-silicon, ithusi, i-nickel, i-chromium, okuqukethwe kwe-molybdenum nokuqukethwe kwe-khromium.

I-A105 izolandela amandla ashubeni, amandla okuthela, ukunwebeka, ukuncishiswa kwendawo, kanye nezidingo zobulukhuni. Imihlahlandlela yokubuyiselwa emuva, ukulungiswa ngokufudumala, nokumaka komkhiqizo kunikezwa.

I-A105 iyinombolo evamile yaseMelika,

Izicucu ze-Carbon zensimbi ASTM A105 ezifakiwe zingama-carbon aphansi, ama-manganese kanye ne-silicon angezelwa ukusetshenziswa kwezicelo ezingabucayi kepha zokucindezela, njengokufaka amazinga okuvimbelani.

I-Carbon Insimbi Esetshenzisiwe ukuze kwazo. Lokhu okuqukethwe kungaba ngesimo sebha noma ngesimo sengoma yokuhlangabezana nesidingo sahlukene sokwakha. Banikela ngemishini ephezulu kanye nokushiswa.

Into ethokozisayo eyenza i-steel ¡®Stainless¡ss¡ i-chromium; Kodwa-ke, ukwengeza i-nickel enika insimbi engagqwali ukuba ibe yi-alloy eguquguqukayo.

I-Carbon Steel A105 Ibanga yonke imikhiqizo efana ne-Flanges, ukufakwa kwezilwandle ze-butt, ukufakwa kwezindawo, izitolo, ibha eliyindilinga enziwe ngezinto zokwenziwa ezisezingeni eliphakeme. Imikhiqizo ye-Carbon I-A105 iyatholakala ngokucaciswa okulandelayo, ibanga nosayizi.

I-ASTM A105 ibanga lensimbi yensimbi ye-carbon enokusetshenziswa okukhulu kakhulu futhi okusabalele. Lokhu kusetshenziselwa ekwakheni izakhi zamapayipi.

Insimbi engenasici isetshenziswe iminyaka engaphezu kwekhulu.

Ngakho-ke, izinto zokwakha ezinokuqukethwe okuphansi kwekhabhoni ezinjengezinto eziphansi ze-ASTM A105 azinconywa ukuthi zisetshenziswe kulezo zinhlelo zokusebenza ezinesidingo sokuvulelwa njalo emazingeni okushisa angenhla kwaleli nani.

Ezinye zazo ziyi-flange futhi zakha ama-fittings. Zingamapayipi amancane abubanzi. Le Carbon Steel Material Grade ye-ASTM A105 ilungele kahle izinhlelo zokucindezela ezidinga insizakalo emazingeni okushisa aphezulu.

Ukufakwa kwe-A105 SOCKET Welld Fittings okujwayelekile yi-Under ± ephathekayo ukwelashwa okushisa, okungenayo noma yikuphi ukucindezelwa kwangaphakathi futhi ngenxa yalokho kube nokwenza izinto eziphakeme.

Ukucaciswa kwe-UNS S31803 (ASTM F51) kudluliselwe kakhulu yi-UNS S32205 (1.4462, ASTM F60). Lokhu kukhombisa isifiso sabo sokwandisa izakhiwo zokugqwala kwe-alloy, ngenxa yokuthuthukiswa kwenqubo yokwenza insimbi ye-AOD, okuvumela ukulawulwa okunzima kokwakheka. Ngaphezu kwalokho, kuvumela ukuthonya izinga lesengezo le-nitrogen kunokuba nje likhona njengento yangemuva. Ngakho-ke, amamaki aphezulu aphezulu kakhulu afuna ukukhulisa okuqukethwe kwe-chromium (CR), i-molybdenum (mo) ne-nitrogen (n).
