Amapuleti ensimbi engagqwali namashidi namakhoyili

I-Duplex Scices inokumelana okuphezulu ezinhlotsheni ezahlukahlukene zokugqwala. I-Duplex Steel S31803 iyi-alloy evimbela kakhulu, enobunzima obuqine. Ama-Flanges we-Duplex Steel S31803 Butt Weld Flanges anezindawo ezinhle zokushisa eziphakeme.

AmaFuplex Flanges aqukethe uhlobo lwezinto ezibonakalayo ezibizwa ngokuthi Duplex. Izinto ezibonakalayo zinezinhlaka zombili ze-Ferritic kanye ne-auntenitic ezenziwe nge-metallurgy. Kunamabanga ahlukene wokuDuplex ngokuya ngokwakheka kwezinto ezibonakalayo. Ama-Flanges ensimbi engagqwali anezakhiwo ezinhle kakhulu ze-ferrititic ne-auntenitic. Zisetshenziswa njengokufaka okunye esikhundleni sama-alloys aphezulu abizayo ezihlolweni eziningi zezimboni.

I-Butt Weld Flanges iyindlela ethandwa kakhulu ye-Pipeline Pepineline Flange. I-Tapered Hub Design of Butt Weld Flanges ihlinzeka ngokuxhumana okuqinile kakhulu, futhi ama-FLD we-Butt Weld angakhokhwa futhi agobe kaningi ngaphandle kokuyekethisa impahla kanye nekhwalithi yokuxhumanisa. I-Butt Weld Flanges nayo inenzuzo yokumelana kakhulu namazinga okushisa aphezulu aphezulu nangaphansi.

I-S32205 Duplex Steel Asme SA182 Butt Weld Flanges ilungele amanzi olwandle nemishini yokukhiqiza amandla ngoba izindawo zabo ezibushelelezi zingamelana namazinga okushisa aze afike ku-600¡ãf, ngenkathi enezimpawu ezinhle kakhulu zokugeleza.

Yize kubalulekile ukukhumbula ukuthi ukugqwala okukhonkotha kungaba ukukhathazeka ngezixazululo ze-chloride lapho imithombo ye-oxidizing ikhona. Kulezi zimo, ungqimba lwe-Passive (lokuvikela) lwe-Duplex 305 Izinto ezibonakalayo zingahle zincishiswe ekuphaphemeni kwasendaweni kungenzeka.

I-A182 gr. I-F51 \ S31803 Izinto ezibonakalayo ziyinsimbi evamile engenacala, equkethe cishe ama-50% Ferrite no-50% Austonite.

2022 unyaka othengiswayo othengisayo ngokunemba okuphezulu kwekhwalithi ephezulu ye-carbon intambo flange

Abahlinzeki bensimbi engagqwali i-flain flainle ancoma leli banga elingenamicikilishelwa imisebenzi ngoba uhla lwamabanga angenasici lufana nohlu lokumelana olungenasici lufana nohlu lokuphikiswa lwensimbi olungenacala, isb.

Njengensimbi ye-alloy ephakathi nendawo, ama-dueplex blind aphakanyiselwe ubuso be-flanges anikela ngokumelana kahle nokugqwayiza kanye namandla emishini kwabezindaba abaningi uma kuqhathaniswa ne-astm evamile ye-astm 316l.

Ama-Flanses ensimbi engagqwali asetshenziswa kabanzi ezinhlelweni zamapayipi, ama-Risers, ama-manholds, njll. Embonini kagesi aphesheya kwezimboni kanye nemboni yamafutha, futhi nasembonini ye-petrochemical ngendlela yemikhumbi yengcindezi namapayipi. I-Duplex 2205 Izinto ze-Flange zinamandla amahle kanye nokumelana okuphezulu ekugqwaneni, okukhonkotha kanye nokugqwala kwe-crevice. Ukwakheka kwamakhemikhali okuhlangene kwe-Duplex 2205 kungama-22% Chromium, 3.2% molybdenum, ama-5% ama-nickel nezinye izinto ezengeziwe ezinjenge-manganese ne-nitrogen.

I-Duplex 2205 kanye ne-Super Duplex 2507 I-Stirless Butt Weld Flanges ifaka amandla aphezulu avuthayo aphindwe kabili amandla okuthela okuvundwa kwamandla ezinsimbi ezijwayelekile ze-auntenitatic ezinjengezinsimbi ezingama-304 kanye nama-3 ezingenazinsimbi ze-butt Weld Weld. Ngenxa yalokhu, i-duplex 2205 ne-super duplex Ama-steelos angama-2507 ngamanye amamaki ajwayelekile asetshenziselwa ama-butt weld flanges, ane-super duplex 2507 butt Weld Weld

I-ASTM A182 F53 VS F55 ingangena ngamadayimane ahlukene asuka? amasentimitha kuya kwangama-intshi angama-48 anamakilasi ahlukene wokucindezela asuka ekilasini 150 ngokusebenzisa isigaba 2500.

I-Duplex 2205 ibonakala ngokumelana okuphezulu ekuqhekezweni kwe-Chloride Screen Corning, i-chloride pitting and crevice corring ukumelana, ukumelana nokugqwala okujwayelekile, ukumelana nokugqwala okuhle kwe-sulfide, amandla aphezulu nokusebenza okuhle.

Le alloy exotic isetshenziswa ekuhlolweni kwamafutha kanye negesi futhi isetshenziswa embonini yokucubungula amakhemikhali. Imishini eminingi yokucubungula isebenzisa i-Duplex 2205. Iphinde isetshenziswe yi-Industrial Storage kanye namayunithi okuhamba. Ama-pulp kanye namaphepha okugaya, amathangi awuketshezi nemishini yamaphepha nawo asebenzisa i-duplex 2205. Ilungele ukusetshenziswa ezindaweni zasolwandle.

Ukusetshenziswa kwe-Duplex kanye ne-Super Dumplex Steel engenacala kufanele kukhawulelwe ngaphansi kuka-570¡ããf, njengoba ukuvezwa isikhathi eside kumazinga okushisa aphezulu kungenza okuthe xaxa.

Amandla okuvutha nawo aphakeme, avumela abaklami bengxenye ukuthi banciphise usayizi wesigaba ngezinhlelo zokusebenza ezithwele umthwalo.

I-Duplex S31803 Butt Weld Flanges ihlanganisa amandla ne-decticity enhle ngokulinganisela ekulweni nokugqwala okuhle ezindaweni ezahlukahlukene. Ama-Flanges ahlanganisiwe we-Duplex S31803 ane-Dreangen iyona esetshenziswa kakhulu ye-Dumplex Grainless grade. I-Duplex S31803 I-FLANGE YOKUXHUMANISA I-FLANES ifaka amandla aphezulu avuthayo aphindwe kabili lokho kwamabanga ajwayelekile we-aututenitic angenasici.
