Aloyi 28 (Wst 1.4563)

Aloyi 28ndi high-aloyi multi-purpose austenitic zosapanga dzimbiri zitsulo kuti azitumikira mu nyengo zowononga kwambiri. Gululi limadziwika ndi:

• Kukana kwa dzimbiri kwambiri mu ma asidi amphamvu
• Kukaniza kwabwino kwambiri kupsinjika kwa corrosion cracking (SCC) ndi intergranular corrosion m'malo osiyanasiyana.
• Kukana kwakukulu kwa pitting ndi corrosion
• Weldability wabwino

Miyezo

Chifukwa cha dzimbiri zake zapamwamba, Sanicro® 28 itha kugwiritsidwa ntchito m'malo osiyanasiyana. M'munsimu muli zitsanzo zingapo za ntchito zomwe alloy iyi ili yoyenera kwambiri.

Phosphoric acid

Lero,Aloyi 28 kapenaSanicro 28 ndizitsulo zomwe zimagwiritsidwa ntchito kwambiri popanga machubu a evaporator popanga asidi wa phosphoric pogwiritsa ntchito njira "yonyowa". Mayunitsi angapo akhala akugwira ntchito kwa zaka zoposa 10. Osinthira kutentha kwa graphite, m'malo mwa Sanicro 28, nthawi zambiri amakhala ndi mavuto mobwerezabwereza ndi machubu osweka komanso kutayika kwa kupanga.

Sulfuri asidi

Aloyi 28 kapenaSanicro 28 ndi zinthu zoyenera zopangira mapaipi ndi zotenthetsera kutentha, makamaka pakati pa 40 ndi 70% ya asidi wa deaerated ndi kupitirira 85%.Aloyi 28 kapenaSanicro 28 ili ndi kukana kofanana ndi Aloyi C mu asidi wambiri (98% H2SO4).

Mafuta ndi gasi

Aloyi 28 kapenaSanicro 28 imagwiritsidwa ntchito popanga machubu, ma casing ndi ma liner m'zitsime zakuya, zowawasa. Zinthuzi zimalimbikitsidwanso pazitsime zamafuta zomwe zimakhala ndi malo owononga. Pazifukwa izi, machubu amaperekedwa ozizira atakulungidwa ndi mphamvu yayikulu. M'malo mwa njira yothetsera vutoli,Aloyi 28 kapenaSanicro 28 imagwiritsidwanso ntchito ngati mapaipi onyamula mafuta owononga ndi gasi komanso osinthanitsa kutentha m'malo ochizira. Mawaya a Sanicro 28 amagwiritsidwa ntchito potsitsa zida ndi zida zowongolera m'zitsime zakuya zamafuta ndi gasi.

Media yokhala ndi fluoride

Mipweya yokhala ndi fluoride imatha kupanga popanga phosphoric acid ndi feteleza wosakanikirana. Mipweya yakunja imeneyi iyenera kutayidwa pazifukwa za chilengedwe. Sanicro 28 ndi yabwino pazifukwa izi. Mayeso awonetsa kuti ndi yabwino kuposa magiredi apamwamba a CrNiMo kuti abwezeretse gypsum yokhala ndi fluoride.

Zida zamagetsi za nyukiliya

Chifukwa cha kukana kwambiri kwa SCC, pitting ndi corrosion, Sanicro 28 yasankhidwa kuti ikhale yosinthanitsa kutentha m'mafakitale amagetsi a nyukiliya.

Madzi ozizira a m'nyanja ndi chloride

Kukaniza kwake kuipitsidwa ndi dzimbiri kumapangitsa Sanicro 28 kukhala chinthu choyenera kwambiri pamapaipi onyamula madzi am'nyanja ndi zotenthetsera zoziziritsa kunyanja. Izi zimatsimikiziridwa ndi chokumana nacho chothandiza.

Sanicro 28 yalowa m'malo mwa ma aloyi a faifi tambala, CuNi, machubu a bimetallic ndi machubu okhala ndi chitsulo cha carbon, omwe adalephera chifukwa cha dzimbiri. Kuchita kwa Sanicro 28 kwakhala kopambana.

M'madzi ozizira otenthetsera madzi a m'nyanja ndi zotenthetsera zomwe zimagwira ntchito ndi madzi ozizira okhala ndi chloride, Sanicro 28 imapereka kukana kwa dzimbiri m'madzi onse komanso sing'anga yozizira.

Chomera chozizidwa ndi madzi a m'nyanja chikazimitsidwa, sipafunikanso kukhetsa mapaipi kapena kuthira madzi abwino, malinga ngati nthawi yotsekerayo ndi yaifupi kuposa mwezi umodzi ndipo kutentha kwamadzi kumakhala kotsika kuposa 30 ° C (85 ° F) .

Chitsulo chosapanga dzimbiri cha duplex 2507 chimakhala cholimba kuposa Sanicro 28 m'madzi am'nyanja.
