Ama-304l Tees ane-redechers

Ukucaciswa kwezinhlobo ze-Flange kwenziwa nge-ASME B16.5 Standards. Ngakho-ke ama-flanges ahlukaniswa ngokuthi; Intamo ye-Weld, ukushelela, iSocket Weld, i-Lap-Joint-Joint. Ama-flanges e-weld entamo kulula ukubona. Ukuqhuma kwe-cylindrical okunokwanda kancane kancane kuxhumeke engxenyeni eyinhloko eyize.

I-Alloy C-276 ichazwa futhi njenge-Alloy C276, i-Inxote C76 noma i-Hastelloy C, okuyi-superlosiy enenhlanganisela ephelele ye-molybdenum, i-nickel ne-chromium. UTungsten ungeziwe, oklanyelwe ukuhlinzeka ngokumelana kahle nokugqwala okuphezulu ngisho nasezindaweni ezinokhahlo.

Izakhiwo ze-alloy zikwenza kube yisinqumo esihle kakhulu sezicelo zamanzi olwandle, kufaka phakathi ukukhululeka ekuhlaseleni kwasendaweni (okukhohlisayo kanye nokugqwala kwama-croring)

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

Le alloy lensimbi ye-nickel isetshenziswe kalula futhi ingahle ifakwe kunoma yisiphi isimo se-annealed noma semvula (yobudala).

Ngakho-ke, ukulungiswa kwama-flanges ashelelayo-on kulula. Kodwa-ke, amandla ama-flanges ashelelayo anama-flanges amabili e-Weld Coud Flanges, ngaphansi kwengcindezi yangaphakathi ngenxa yokugeleza. Okunye okubi kwama-flanges okushelelayo ukuthi kungukuthi izingxenyana ezingenzeki ukuthi zilungise i-flange ku-elbow noma zilungise i-flange ku-tee ngoba indawo yokugcina ye-slip-on the slittings ayiqondile. Iqembu lesithathu le-Flange i-Socket Weld Flanges. Lawa ma-flanges asetshenziselwa amapayipi amancane okumele athele izingcindezi eziphakeme. Amandla we-Socket Weld Flenges ngokubhekisisa izingcindezi zangaphakathi alingana nokushelela-ama-flanges.

IHastelloy C-276 iphinde imelane kahle nokugqwala okukhohlisayo, ukugcwala kokugqwala kwengcindezelo nokuqhekeka kwe-oxidizing atmosheres, kanye nokumelana okuhle kwezindawo eziningi zamakhemikhali.

Akunakuba lukhuni ukwelashwa okushisa; nokho? Izinto ezibonakalayo zizoqina ngenxa yokusebenza kubanda.

I-Monel K500 iyinhlangano ye-nickel-Copper Alloy ehlanganisa isimilo esihle kakhulu sokulwa nokugqwala kwe-monel 400 ngenzuzo eyengeziwe yamandla amakhulu nobulukhuni.

Kodwa-ke, amandla abo okukhathala aphakeme kunama-flanges ashelelayo. Inkinga enkulu yeSocker Weld Flanges yingozi yokugqwala. Igebe phakathi kwe-flange nokufaneleka noma ipayipi kufanele ligcinwe ngaphambi kokushiswa. Uketshezi olulimazayo noma umswakama lungathola kulezi zindawo zokukhosela. Ngakho-ke, lesi sibonisi esinamanzi aqinile singadala ukugqwala emzimbeni.

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.

I-Alloy 254 SMO ukuphela okuphezulu, i-molybdenum ne-nitrogen allOred Super Auntenitic insimbi engenacala ngokuqukethwe okuphansi kwekhabhoni.

Ukuze uthole insizakalo edinga ama-creep alungile kanye nokuqhuma kwezakhiwo, incoloy 800h noma ama-800 ht asetshenzisiwe. Okuqukethwe okuphezulu kwe-nickel ne-chromium kuma-allomium kunikeza nokumelana okuhle kokugqwala.

Lokhu kuxhumana kufakwa ngaphakathi kwezindonga zikakhonkolo ngaphambi kokuthululwa kokhonkolo. Lolu hlelo kumele luhambisane kahle ngaphambi kokuthulula ukhonkolo ngoba ludinga ukumelana nesisindo namandla wesakhiwo.

I-Incontol 625 2.4856 PIPE NE-SPOOL DIBALLS YOKUQHAWULA KAKHULU

I-Hastelloy C276 ingenye yama-alloys ambalwa amelana ne-wet chloride gesi, i-hypochlori ne-chlorine dioxide solutions.

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.

Ama-Tees nawo asetshenziselwa ukuguqulwa kwe-angle yokugeleza nokusatshalaliswa kwento egelezayo kungaba esiteshini esisodwa noma ngaphezulu. Tees ingahlukaniswa ngamaqembu amabili aphambili okuyi-butt welded tees kanye ne-socket i-Welded Tees. I-Butt Welded Tees isetshenziswa ukwenza ukusatshalaliswa kwe-perpendicular kokugeleza. Benza amagatsha angu-90¡Ã0¡Ã axhumano ngepayipi futhi asabalalise udaba oluzayo kusuka ku-mainline.

I-Inxotemensi 718 2.4668 I-Pipe Peabrication ewusizo ebangeni eliwusizo emikhathini

Ine-nickel ephezulu (24%), i-molybdenum (6.3%), i-nitrogen kanye nokuqukethwe kwe-chromium okunikeza ukumelana kahle nokuqhekeka kokugqwala kwe-chloride, i-chloride ukumelana, kanye nokuphikiswa okujwayelekile kokugqwala.

I-Hastelloy iyinhlangano ye-nickel engamelana ne-cororion equkethe ezinye izinto zamakhemikhali ezifana ne-chromium ne-molybdenum. Lokhu okuqukethwe kunokumelana okuphezulu kokushisa kanye nokuphikiswa okuhle kakhulu kokugqwala. I-Hastelloy C276 ingenye yamabanga aseHastelloy asetshenziswa embonini kawoyela negesi.

Isetshenziselwa izakhi ezidinga ukuvezwa kwamanzi olwandle kanye nengcindezi ephezulu yemishini.

I-Chromium, i-molybdenum ne-nitrogen kukhulisa ukumelana nokugqwala okukhonkotha. I-nickel ifaka isakhiwo se-auntenitic.

Ukumelana nohlobo oluthile lwemidiya elonakalisayo. Okuqukethwe kwe-chromium kunikeza ukumelana okungcono kune-alloy 200 nango-201 ngaphansi kwezimo ezi-oxidizing, ngasikhathi sinye, isikhathi esiphakeme i-nickel inikeza ukumelana kahle nokunciphisa izimo.

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).

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.

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

Yakhelwe ukumelana nokuvuselelwa okuthuthukile kanye namandla aphezulu emazingeni okushisa angenhla kwe-1000¡Ãf (537¡Ãc).

Inokumelana okukhulu ekuqhekekeni kwengcindezi - ukuqhekeka kokugqwala nokukhonkotha. Hastelloy B-2? Futhi ifaka ukumelana ne-hydrochloric acid kuwo wonke amazinga okuhlala kanye namazinga okushisa.
