nickel alloy hastelloy c276 ngama-flanges

Amapayipi aluhlaza anqunywe osayizi abadingekayo futhi ahanjiswe ngamapayipi etafuleni elifanele, lapho ezinye zezakhi zihlanganiswa ndawonye (I.E. zixhunywe okwesikhashana). Umhlangano ongaphansi ophumelelayo (ingxenye yepayipi lokugcina lepayipi) uyaqhubeka nokusebenza kwe-welding (i.e. exhunywe ngokuphelele) ngaphambi kokuthi ibuyele etafuleni elifanele futhi lilinganiswe nezinye izingxenye ze-spool.

I-Hastelloy B2 ivimbela ukwakheka kwe-carbide ye-carbide yokusanhlamvu endaweni ye-weld Heart athintekile zone, okwenza kube lulungele izinhlelo eziningi zenqubo yamakhemikhali esimweni se-as-welded. Indawo ethintekayo ye-Weld Ethintekile yehlisa indawo yemvula ye-carbides nezinye izigaba ukuqinisekisa ukumelana nokugqwala okufanayo.

Ukumelana ne-Chloride Ion Corrision kungenye yezinto eziphambili ezenza kube lula ukusetshenziswa kwamabanga we-incoloy ezihlolweni ezahlukahlukene zezimboni.

Lesi sigaxa sepayipi esingenasici sivame ukuthathwa ukuze sikwazi ukwenza ukuxhumana kwamanye ama-spools futhi sithanda kakhulu ezisetshenziselwa izimboni ezahlukahlukene ezinjengezitshalo zamandla kanye nokuhlaziywa kukaphethiloli zidinga amapayipi afudumele.

I-Incons 718 iqukethe ngokuyinhloko i-nickel (52%). Izakhi zezabelo zifaka i-iron (19%), i-chromium (18%), i-niobium + tantalum (5%), i-aluminium (0.5%), ngaphezu kwezinye izindlela zokulandela umkhondo njengeBaron, iCobalt, i-MANnganese kanye ne-Silicon.

I-NIKEL- NE-CORLOSION esekelwe ku-corovion-, ama-alloys wokushisa- kanye nokugqoka - okuvinjelwe, anjenge-hastelloy B2, ahlukaniswa njengomanzi okulinganiselwe ukukhiqizwa ngejubane eliqinile, kepha kufanele kukhiqizwe ama-alloys akhiqizwa ngezindlela ezikhulayo ezisebenzisa izindlela ezenzelwe ukukhiqizwa. Ngesikhathi semishini, lezi zinhlaka ziqinisa ngokushesha, zikhiphe ukushisa okuphezulu ngesikhathi sokusika, i-weld kuya ebusweni ithuluzi lokusika, futhi kunikeze ukumelana okuphezulu kokukhishwa kwensimbi ngenxa yamandla abo aphezulu.

Le alloy iyamelana nokwakhiwa kwemingcele yokusanhlamvu ethambekele endaweni ephazamiseka ukushisa, ngaleyo ndlela okwenza kube lulungele izinhlelo eziningi zenqubo yamakhemikhali esimweni se-welded.

Amandla ale ncwadi yensimbi ye-nickel igcinwa ku-1200¡Ã fy kodwa ihlala i-ructile futhi igxile emazingeni okushisa ka-400¡Ã f. Ibanga layo elincibilikayo lingu-2400-460¡Ã f.

I-Alloy 800 inokumelana ngokulinganiselayo kokuphikiswa kwemidiya eminingi enamanzi futhi iyamelana nokuqhekeka kokuphazamiseka ngenxa yokuqukethwe kwayo kwe-nickel. Emazingeni okushisa aphezulu, inokumelana ne-oxidation, ukuqeqeshwa kanye nokuvuselela kanye nokuqhekeka kanye namandla okuqina.

I-Alloy K500 yacwengiswa ngu-Electro Slag Refining (ESR), ukuqinisekisa ukuthi ikhwalithi ehlanzekile futhi ephezulu kakhulu yezinto ezibonakalayo iyahlinzekwa.

Ama-flanges ahlangene ane-lap anesimo esilinganayo esifana neSocket Weld Flenges ngaphandle kwegebe le-Weld. Ngakho-ke, ukusetshenziswa kwabo kuzinhlelo zokusebenza ezingadala ukugqwala kunzuzo. Olunye uhlobo lwe-flange amafulethi afakwe intambo. Ama-flanges ahlanganisiwe asiza kakhulu kwizicelo ezithile ngoba azidingi ukuthutha ukulungiswa.

I-HT izokwakha lezi zinhlaka futhi izonikeza njengephakethe eliphelele njenge

Izidingo zeklayenti¡. Futhi singanikeza okususwayo kokusebenza okuqukethwe okuqukethwe okuqukethwe, kufaka phakathi amamojula wokusika amapayipi, ukubheja, ukuhlangana futhi

I-ASTM A790 S32205 ipayipi elingenamikhumbi lensimbi engenasici

Ama-spools ensimbi angenasici asebenza kumakhasimende ngoba awaphuthelwa noma yiziphi izingxenye futhi asusa ubunzima bokufakwa kwe-inkazi.

Inani lama-welds ku-spool kumele ligcinwe ukubala okuncane. Ubukhulu besikhala phakathi kwezindawo eziphakathi nendawo kanye nemigqa yesikhungo akumele ibe mikhulu kuneziphindwe kane udonga lwepayipi noma efanele. Ngemuva kwama-welds amakhulu, ama-tacks welds kumele enziwe ngokunembile. Zonke ama-welds e-spools kumele zisetshenziswe ngokuya ngokucaciswa kwenqubo ye-welding efanele (i-WPS). Ngemuva kokuthi inqubo ye-welding yenziwe, ukulawulwa kwekhwalithi kwezakhi kwenziwa ngochwepheshe.

Ezinye izinhlelo zokusebenza ezijwayelekile ze-Incontel 625 zifaka ukucubungula kwamakhemikhali, i-aerospace kanye nobunjiniyela basolwandle, imishini yokulawula ukungcoliswa kanye nokuphendula kwenukliya.

Enye yezinto ezehlukanisa ukwahlukanisa kwe-Incon 718¡¯s ukwakheka kwe-niobium ukuvumela ubusuku obuvumayo obuvumela ukuhlanganisa nokushiswa ngaphandle kokuqina kokushisa nokupholisa.

Amapayipi spools yizingxenye zangaphambi kokwakha kohlelo lwamapayipi. Amapayipi, ama-flanges, kanye nokufakelwa abizwa ngokuthi ama-Pipe Spools futhi akhiqizwa ngaphambi kokuthi asetshenziswe ohlelweni lwamapayipi.

I-Plasma Arc Cutter isetshenziselwa amapayipi amakhulu (ngenhla kwama-intshi angama-28 wosayizi wepayipi oyisikhonkwane) nokusetshenziswa kwayo nakho kuzuzisa ukusika amagatsha. Uma kungenzeka, icala langaphakathi kumele libe ngamapayipi noma ukufakwa, ukuze livikeleke eziswindi ezidalwe yi-plasma arc cutter. Ngemuva kokusika, nokulungiselela onqenqemeni kumele kugcinwe.

Imiphetho engaphezulu yezakhi kumele ibe nokungcola komhlaba kufanele kususwe. Inqubo ebhekisisa isetshenziswa emaphethelweni ezingxenye. Kuqashwa umshini wokugaya inqubo ye-Beving. Uhlobo lwemishini yokugaya ye-beveling yehluka ngezakhi zensimbi ezingagqwali nezakhi zensimbi zekhabhoni.

Isici seHastelloy B3 esihlukanisayo amandla asilo okugcina isikhala esihle ngenkathi kuchayeka ngokushisa okuphakathi nendawo.

Amapayipi angama-304 enziwe ngensimbi engama-304 engagqwali, impahla ejwayelekile futhi ethandwayo kuzinhlelo eziningi zezimboni ezidinga ukumelana nokugqwala kanye noximation. Lawa mapayipi amapayipi e-S30400 ahlanganiswe asebenzisa imishini ekhethekile nezinqubo, eziqinisekisa ukuthi zinembe kakhulu futhi zithembekile.

I-Hastelloy C-22 ne-C-276 yizinto kuphela ezivimbela ukugqwala kumanzi chlorine, i-hypochlori, kanye ne-chlorine dioxide solutions, ngokumelana okukhulu kwezixazululo eziphakeme ze-chloric ezinjengama-forric nama-cupric. Ukumelana nokugqwala.

I-Al6xn isetshenziselwa ikakhulukazi ukumelana nokugqwala kwayo okuthuthukile kanye ne-crevice in clorides. Kuyinsimbi enobunzima futhi engakhathali.

Inani lama-welds ku-spool kumele ligcinwe ukubala okuncane. Ubukhulu besikhala phakathi kwezindawo eziphakathi nendawo kanye nemigqa yesikhungo akumele ibe mikhulu kuneziphindwe kane udonga lwepayipi noma efanele. Ngemuva kwama-welds amakhulu, ama-tacks welds kumele enziwe ngokunembile. Zonke ama-welds e-spools kumele zisetshenziswe ngokuya ngokucaciswa kwenqubo ye-welding efanele (i-WPS). Ngemuva kokuthi inqubo ye-welding yenziwe, ukulawulwa kwekhwalithi kwezakhi kwenziwa ngochwepheshe.

Amabanga amabili ajwayelekile ensimbi ajwayelekile angama-304 no-316. Umehluko omkhulu ukufakwa kwe-molybdenum, i-alloy ethuthukisa kakhulu ukumelana nokukhulisa, ikakhulukazi ezindaweni ezinosawoti noma nge-chloride.

Alloy 347 (uns s34700) nguColumbium waqinisa ipuleti yensimbi engenacala engenacala ngokumelana kahle nokuphikiswa okujwayelekile kanye nokuphikiswa okungcono ezimweni eziqinile ze-oxidizing eziqinile kune-321 (uns s32100).
