Ukucaciswa kwe-Invar 36: Ama-K93600, W.NR 1.3912
I-Alloy 20 (Alloy 20) iyinhlangano ye-autenquitic esekwe ngensimbi eyenzelwe ukumelana nokugqwala kwe-sulfuric acid. Inokumelana okuhle kakhulu kwe-sulfuric acid corrision; Inokumelana okuqinile kwe-phosphoric acid, i-nitric acid kanye ne-chloride ezindaweni, ukugqwala okucindezela kwe-chloride, ukugqwala okukhonkotha kanye nokugqwala kwe-crack. Ngakho-ke, Alloy 20 unegama le-anti-corriosion alloy; Inezinhlobonhlobo zezicelo: njenge: Chemical, ukudla, umuthi, ukukhiqizwa kwamandla kanye nezimboni zepulasitiki kuzoyisebenzisa. Ukuze ukumelana nokugqwala okukhonkotha kanye nokugqwala kwe-chloride, izinkinga zokugqwayiza kwengcindezelo, njll., Alloy 20 kuvame ukusetshenziswa.
Indlela yokumaka yensimbi engagqwali i-American Iron ne-Institute yensimbi isebenzisa izinombolo ezintathu ukumaka amamaki ajwayelekile ahlukahlukene wensimbi engenacala. Phakathi kwazo: ¢ Ama-Steautusnitic ama-stainless angenazimpawu amakwe ngezinombolo ze-200 neze-300. Isibonelo, ezinye izinsimbi ezijwayelekile ze-auntenitic ezingenasici zimakwe ngo-302, 304, 316 no-310, ¢ úferritic kanye ne-martensitic ama-sterments anyatheli asetshenziswa inani lochungechunge lwe-400 limelelwa. Ng ûferritic insimbi engagqwali imakwe ngo-430 no-446, insimbi engenacala elingenacala imakwe ngo-410, 420 no-440c, i-duplex (i-auceple-ferrite), ¢ Insimbi evuthayo yensimbi engenasici kanye nama-alloys aphansi avame ukuba nelungelo lobunikazi noma afakwe uphawu
Amapayipi ensimbi ye-alloy asetshenziselwa ukushisa okuphezulu kanye nensizakalo yokushisa ephansi kakhulu (lokushisa eliphansi) embonini yamandla, noma izicelo eziphakeme kakhulu zokucindezela. I-ASTM A335 Alloy Steel Pipe ilungele ukufakwa kwezinsimbi ze-ASTM A234 WPX Butt Weld Zonke lezi zinto zokwenziwa zinezakhiwo ezifanayo zamakhemikhali nezemishini futhi zingajoyina noma zifakwe.
Ukumelana okuhle kokugqwala kuma-acid kanye ne-alkalis futhi kuwusizo kakhulu ngaphansi kwemibandela yokunciphisa. Ukumelana okuvelele kwe-caustic alkalis kuze kufike futhi kufaka phakathi isimo esincibilikisiwe. Ku-acid, i-alkali kanye nezixazululo zikasawoti ezingathathi hlangothi Izinto ezibonakalayo zibonisa ukumelana okuhle, kepha kuzixazululo zikasawoti oxegatizing aspar attack kuzokwenzeka. Ukumelana nawo wonke amagesi owomile emazingeni okushisa asekamelweni nase-chlorine eyomile ne-hydrogen chloride kungasetshenziswa emazingeni okushisa aze afike ku-550c. Ukumelana nama-acid angamaminerali kuyahlukahluka ngokuya ngokushisa nokuhlushwa nokuthi ikhambi liyabonakala noma cha. Ukuphikiswa kokugqwala kungcono e-acid ye-de aerated.
I-A335 I-Pipe yensimbi ingasetjenziswa kwizicelo ze-NACE ekushiseni okuphezulu kanye nengcindezi ephezulu ezindaweni ezihlonishwayo, zingasetshenziswa ku-NACE-MRO 175 insizakalo emuncu, ikwazi ukuphatha amazinga okushisa aphezulu, angakwazi ukubhekana namazinga okushisa aphezulu anokuqina okuphansi kakhulu.
Sinikezela ngohlobo olubanzi lwe-ASTM A335 P9 ALLOY STORE STE STIAMLET PIPS usebenzisa izinto ezisezingeni eliphakeme eziluhlaza. Lawa mashubhu wensimbi ensimbi ye-alloy e-alw akhiwe phakathi kuka-2250¡Ãf \
12¡Ãc \
1230¡Ãc \
955¡Ãc Lawa ngamapayipi e-P9 e-A335 akhiqizwa kumazinga wekhwalithi yamazwe omhlaba. Lawa ma-alloy ensimbi p9 amapayipi angenamthungo nawo ayatholakala ngosayizi ahlukene, amamaki, ubukhulu kanye nokucaciswa ngokuya ngezidingo zamakhasimende.
I-SA182 Plate Flanges ingasetshenziswa ezindaweni lapho kunamakhompiyutha anolaka olunolaka. Ingasetshenziswa futhi kuzicelo ezingezona ezonakalisayo kanye nezicelo ezinolaka emazingeni okushisa aphakathi kuka-30? C kuya +650? C.
