I-ASTM A240 304 304L amapuleti ashushuluzayo ama-US 20400 Sheet
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-Flanged Joint yakhiwa okuhlukile okuhlukile futhi okuzimele yize izingxenye ezihlangene; amafuvu, ama-gaskets, kanye ne-bolting; aqoqwe ngelinye ithonya, i-fitter. Izilawuli ezikhethekile ziyadingeka ekukhetheni nasekusetshenzisweni kwazo zonke izinto ezikhona ukuthola okuhlanganisiwe, okunokuqina okuvuzayo okwamukelekayo.
I-Al6XN iyinsimbi e-superAustonitic engenacala ngokumelana okuvelele kokuphamba kwe-chloride, ukugqwala kwe-crevice kanye nokuqhekeka kokugqwala kwengcindezelo. I-Al6xn ingu-Aloy ayi-6 olwenzelwe futhi asetshenziswa ezindaweni ezinolaka kakhulu. 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-Al6xn isetshenziselwa ikakhulukazi ukumelana nokugqwala kwayo okuthuthukile kanye ne-crevice in clorides. Kuyinsimbi enobunzima futhi engakhathali.
Insimbi engagqwali 304 \
30L Flanges ingahle yenziwe ngokuya nge-ASME B16.5 noma i-ASME B16.47 ngokuqanjwa okungu-18cr-8ni. Incwadi ¡° l¡ ± isho inguqulo ephansi yekhabhoni yensimbi engama-304 engagqwali. Ama-flanges angenziwa ngenxa yokuqapha, ama-castings, noma amapuleti amboza izinhlobo ezahlukahlukene namakilasi e-ASME B16.5 ne-ASME B16.47 (bobabili uchungechunge A no-Series B). Insimbi engagqwali 304 \
304l Flanges of Asme B16.5 ayatholakala emakilasini 150, 300, 400, 600, 900, 1500, 2500, 2500, 2500, 2500, 2500, 1500, 2500, 1500, 2500, 1500, 2500, 1500, 2500; Lokho kwe-ASME B16.47 Series A kuyatholakala emakilasini 150, 300, 400, 600, 900; Lokho kwe-ASME B16.47 B kuyatholakala ekilasini 75, 150, 300, 400, 600, 900.
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).
