I-ASME B16.5 I-Standard Covers Insimbi Flanges ye-Steel Flanges kanye nokufakwa kwamapayipi okuvela ku-NPS 1 \ 2 kuya ku-NPS 24 metric
Njengoba sonke sazi, ama-flanges asetshenziselwa ukuxhuma amapayipi amabili, amaphampu nama-valve. Lokhu kungukumelana nokukhulisa, ngakho-ke izinto ezisezingeni eliphezulu zisetshenziselwa ukwenza lo mkhiqizo. I-SA 182 F304 FLANSEs, eyaziwa nangokuthi ama-flanges wensimbi engenasici, ayatholakala kumabanga ahlukahlukene, amasayizi nezingcindezi eziphakeme. Amasayizi ahlukahlukene kanye namapharamitha alo mkhiqizo ayatholakala.
Ama-flases we-hastelloy C276 enziwe nge-nickel-chromium-molybdenum alloy ebizwa nge-hastelloy. Ukwakheka kufaka phakathi i-50.99% nickel, i-14.5% chromium, i-15% molybdenum nekhabhoni, i-manganese, i-silicon, isibabule, i-cobalt, i-irosphorus. I-Hastelloy C276 FLANES inendawo ephezulu yokuncibilika yama-degree angama-1370 Celsius.
Ezindaweni ezinzima kakhulu ezilimazayo, inhlanganisela ye-nickel ne-chromium inikezela ukumelana namakhemikhali oxidizing, kanti okuqukethwe okuphezulu kwe-nickel kanye ne-molybdenum kunikeza ukumelana nezimo ezingezona zoxidizing.
Thayipha insimbi engama-304 engagqwali ibizwa ukwakheka kwayo, okubandakanya i-chromium engu-18% ne-8% nickel. Le nsimbi engenacala inokwakheka okuhle nokushaywa kwe-weldatiability. Ngenxa yokwakheka kwayo, ama-flain angenasici angama-304 ama-flanges angama-304 amelana kakhulu nokuqina okuhlala isikhathi eside.
I-ASTM A182 insimbi engagqwali i-304l iyi-carbon flange ephansi engekho-nonmagnetic lapho incishwa kepha ukhula lapho kubanda. Ikhabhoni ephansi inciphisa amandla okulima amakhabhisi ayingozi.
Okuqukethwe okuphezulu kwe-Alloy Flanges ama-Infol Akukacishe kungabikho ukugcwala okwanele ama-Flanges ezindaweni ezithambile ezinjengomoya, amanzi olwandle, usawoti ongathathi hlangothi, kanye nemidiya ye-alkali.
Ama-flases ethu we-SS 317 amukelwa kahle ngamakhasimende ekusebenzeni kwawo okuthembekile, ukuqina kanye nokumelana okuhle nokugqwala nokugqoka. I-SS 317 i-auntenitic-equkethe i-auntenitic alloy enamandla akhuphuke kakhulu ngokuqhathaniswa nama-general Chromium-Nickel Alloys afana ne-SS 304 ne-SS 316l.
317 \ 317l yi-molybdenum equkethe insimbi ye-autenitic enokuqukethwe okuphansi kwekhabhoni. Okuqukethwe okwengeziwe kwe-chromium, i-nickel ne-molybdenum kwenza ukugcwala kwebanga lonke kanye nokungabekezeleleki kwamakhemikhali. Inokuqina okuthembekile emazingeni okushisa aphezulu futhi inikezela ngezinga elingenakuqhathaniswa lokulwa. Lezi zindawo ze-SS317 \ 177l zisiza ukusetshenziselwa kwayo kwizimboni ze-aerospace nensimbi. Ngaphezu kwalokhu, ama-SS 317 \ 17l Flanges anokumelana okuhle kakhulu ekugqwalisweni kwezinto zokugqwala.
Ama-flauses we-253ma ensimbi ajwayele ukuklanywa ngokucindezela okuphansi, izinhlelo ezingezona ezijikelezayo zezimboni. Lawa ma-253ma Flanges asetshenziswa ngokujwayelekile ezimweni zokucindezela eziphansi.
Ama-flanges we-buttless butt we-butt akhiqizwa eBangeni le-304 ne-316 auntenitutic agninlessnsimbi. Kodwa-ke, kunezinye izinhlobo zezinto ezibonakalayo ezinjengensimbi yekhabhoni, i-duplex steel kanye nensimbi ephezulu yensimbi esetshenziselwa ukwenza ama-flaseses.
Ama-Flanges ensimbi angama-316l ayindlela yokuxhuma amapayipi, ama-valve, amaphampu neminye imishini yokwenza uhlelo lwamapayipi. Kusiza nokuhlanza, ukuhlola noma ukuguqulwa.
Ngensimbi engagqwali engama-316 Flanges, i-molybdenum yinto ebanikeza okuthile okukhethekile: ukuthuthukiswa kokugqwala okuthuthukisiwe. Ama-flanges ethu we-SS 316
I-SA182 F304 inezakhiwo ezinhle kakhulu kanye ne-welding. I-autenitic ye-auntenitic microscucture yama-304 ama-flanges ensimbi engenasici inika amandla umdwebo ojulile ngaphandle kwesidingo sokuvela okuphakathi.
I-Stainless Steel 316 yibanga elingenamikhawulo elingenacala eline-4% molybdenum ekwakhiweni kwalo. Okuqukethwe kwe-chromium, i-nickel ne-molybdenum yenza insimbi engagqwali engama-316 inamandla, ukumelana nokugqwala kanye ne-ductile.
Ama-flainless angenasici angama-317l yindlela yokuxhuma amapayipi, ama-valve, amaphampu neminye imishini yokwakha uhlelo lwamapayipi. Kusiza nokuhlanza, ukuhlola noma ukuguqulwa.
Lawa ma-flanges anokumelana okuhle kakhulu kokugqwala uma kuqhathaniswa nama-flanges ensimbi angama-304. Senza insimbi engenasici angama-316l ama-Flanges aphezulu asezingeni eliphakeme ukuze asetshenziswe kumapayipi ezimeni ezibucayi. Le ngensimbi engenacala.
