Incoloy 825 (Nickel Alloy 825 / UNS N08825) Ruswa - Umuyoboro wa Nickel Alloy Umuyoboro na Tube - BLOG

Iriburiro: Amavuta meza yo Kurengera Ibidukikije bya Shimi

Incoloy 825, bizwi kandi nkaNickel Alloy 825cyangwaUNS N08825, ni hejuru - imikorerenikel - icyuma - chromiumyazamuye hamwemolybdenum, umuringa, na titanium.
Yashizweho byumwihariko gukora munsiacide, chloride, hamwe na - ubushyuhe bwangirika, kuyigira kimwe mubikoresho byinshi muburyo bwa chimique, peteroli, na marine.

Amavuta yerekana ibintu bidasanzwe bihuza imitungo:

Kurwanya bihebuje kurikugabanya no guhagarika aside(harimo aside sulfurike na fosifori).
Umutekano muke urwanyagutobora, kurigata kwangirika, no guhangayika - guturika.
Imikorere idasanzwe nyumagusudira cyangwa kumara igihe kininiku bushyuhe bwo hejuru.

Kwizerwa kwayo kwatumye Alloy 825 ibikoresho bikundwa kuriguhanahana ubushyuhe, kondenseri, ibyuka, hamwe nu miyoboro yo hanze, aho ruswa n'umunaniro wa mashini bibana.

Ibigize imiti nuburyo buhamye

Imikorere ya Alloy 825 ituruka kubitondekanye neza:

Ikintu	Ibirimo (%)	Uruhare rwa Metallurgical
Nickel (Ni)	38.0 – 46.0	Kurwanya ruswa, ituze ryimiterere
Chromium (Cr)	19.5 – 23.5	Kurwanya Oxidation, gukora firime ya pasiporo
Icyuma (Fe)	Kuringaniza	Matrix yuburyo bwo gukomera
Molybdenum (Mo)	2.5 – 3.5	Kurwanya kugabanya itangazamakuru no gutobora
Umuringa (Cu)	1.5 – 3.0	Itezimbere kurwanya acide sulfurike na fosifori
Titanium (Ti)	0.6 – 1.2	Ihamye kurwanya ruswa
Mn, Si, C, S.	Ntabwo ari munsi cyangwa bingana na 1.0 / 0.5 / 0.05 / 0.03	Komeza kugira isuku no gukora

Uwitekatitaniumitanga uburyo bwo kurwanya ubukangurambaga no gutera ibitero nyuma yo gusudira cyangwa guhura na dogere 540-870.

Uburyo bwo gukora no kuvura ubushyuhe

Incoloy 825 imiyoboro nigituba bikozwe binyuzeIbisobanuro - bigenzurwa gushonga, gukora, no gukemura annealingkwemeza microstructure imwe nimyitwarire isumba iyindi.

Incamake yumusaruro

Vacuum cyangwa Argon Gushonga- Kuraho umwanda kandi birinda gutandukana mugihe cyo kuvanga.
Gushyuha Bishyushye / Igishushanyo gikonje- Iremeza kugenzura neza no kwibanda.
Automatic Orbital Welding(kubwoko bwo gusudira) - Bitanga neza, byuzuye byuzuye.
Igisubizo Annealing (dogere 940–980)- Kumenagura karbide no kugarura guhindagurika.
Kuzimya Umuyaga Wihuta cyangwa Amazi- Irinda re - imvura nuguhagarika umutima.
Gutoranya na Passivation- Kugarura chromium - firime ikungahaye kuri okiside hejuru.
Ikizamini cya nyuma cya NDT na Hydro- Yemeza ubunyangamugayo bwimbere no gusudira neza.

Buri cyiciro cy'umusaruro gihuye naASTM B423 / B705 / ASME SB423kandi biranyuraultrasonic, eddy iriho, hamwe na hydrostatike yipimishankuko ASTM B829 ibivuga.
Microstructure yavuyemo ni amatrike imwe ya austenitishamwe no gukwirakwiza karbide hamwe nicyiciro cya intermetallic, bitanga ihame ryiza muri serivisi ya acide.

Kurwanya Ruswa n'imyitwarire ya serivisi

Alloy 825 ikozwe muburyo bwo kurwanya ibintu byinshi byangiza inganda:

Ibidukikije	Imyitwarire yo Kurwanya Ruswa
Amazi ya sulfuru, fosifori, aside aside	Imikorere idasanzwe murwego rwa okiside no kugabanya ibihe
Amazi yo mu nyanja na Chloride Ibisubizo	Kurwanya cyane guhangana, gutobora, no guhangayika - kumeneka
Sour Gas / H₂S	Nickel na molybdenum birinda sulfide guhagarika umutima
Ibidukikije bivanze na Acide	Umuringa na molybdenum byongera imbaraga zo kugabanya aside
Kohereza - Kumenyekanisha gusudira	Titanium irinda igitero hagati yizunguruka

Amavuta avanze akwikorera - gukiza oxyde, kwemeza kurinda - kurinda igihe na nyuma yo gukanika imashini cyangwa kugaragara.
Ibi bituma Alloy 825 nziza kuriaside - ibice bitunganya, imirongo ikonjesha amazi yinyanja, sisitemu yo kurwanya umwanda, hamwe nubushakashatsi bwimiti.

Imikorere ya mashini na Dimensional

Ikizamini cyo Kwangirika hagati (ASTM G28 Uburyo A)
Ihitamo rya gatatu - Kugenzura Ishyaka (SGS, TUV, BV)

Ibicuruzwa byose byatanzwe hamweEN 10204 3.1 / 3.2 MTC, ibisobanuro byuzuye, hamwe na ISO 9001 ibyangombwa byujuje ubuziranenge.

Inganda

Ubwinshi bwa Alloy 825 butuma ikoreshwa mubikorwa bitandukanye byinganda:

Ibimera n’ifumbire- Impumuro ya aside, iminara ya reaction, scrubbers
Sisitemu ya peteroli na gazi- Gukonjesha amazi yo mu nyanja, byakozwe - inshinge
Ubushyuhe bwo guhinduranya hamwe na konderesi- Uturere twinshi twangirika mu nganda n’amashanyarazi
Sisitemu yo kurwanya umwanda- Flue gas desulfurisation, ibice byo kugarura aside
Ubwubatsi bwo mu nyanja- Gukonjesha gukonjesha hamwe nu miyoboro ya desalination

Ihuriro ryayokwihanganira ruswa, gusudira, hamwe nubushyuhe bwumuriroitanga serivisi zizewe mubirere byangiza cyane cyangwa bivanze.

Tanga kwizerwa no gutera inkunga umushinga

Umuyoboro wa Octal uratangaIncoloy 825 / Nickel Alloy 825 / UNS N08825imiyoboro hamwe nigituba binyuze munzira zemewe zo gukora, inyandiko zuzuye, no kubahiriza imishinga mpuzamahanga.
Buri cyiciro cyubushyuhe kirashobora gukurikiranwa, kugeragezwa, no gutangwa hamwe na dosiye yo kugenzura ikwiranyeImishinga ya EPC hamwe nubushobozi bwo gutunganya inganda.

Hamwe nigihe kirekire - ubufatanye bwigihe hamwe nuburambe bwibikoresho, Umuyoboro wa Octal utanga itangwa rihoraho hamwe nubufasha bwa tekiniki kuriimiti, marine, hamwe na - ubushyuhe bukoreshwakwisi yose.
