Duplex idafite ibyuma

Duplex Icyuma kitagira ingano bivuga ibikoresho bifite imishinga igizwe na Ferrite na Austete, buri gihe ibaruramira 50%. Mugukoresha nyabyo, birakwiye cyane kuri kimwe mubice biri hagati ya 40-60%.

Ukurikije ibiranga imiterere y'icyiciro cy'icyiciro cy'icyiciro cy'icyiciro cy'ibiciro byombi, nukugenzura neza imiti ifite neza imiti, ubushyuhe buhebuje kandi bukaba duharanira ibyuma bikabije hamwe n'ibyuma bikabije bitera imbaraga, imbaraga nyinshi kandi zitunganya. Imitungo yabo ifatika iri hagati yicyuma kidashira hamwe nicyuma kidafite umuvuduko, ariko hafi yicyuma cya Feritique na Karuboni. Kurwanya chlorideshiti ya chloride na crevice ya duplex ya duplex idafite ibyuma bidahuye nibikubiye muri chromium, Molybdenum na azote. Kurwanya kwangirika no kunanirwa bishobora kumera kubw'icyuma 316 bidafite ingaruka, cyangwa hejuru kuruta ibyuma bidafite amazi, nka 6% MO Auseling Stoel. Amababi yose adafite imbaraga arashobora kwihanganira cyane ko chloride ishimangiraga koroshya ibimera birenga 300 austenitic ibyuma bidafite ishingiro, kandi imbaraga zabo nazo zirenze ibyuma bidafite isuka, mugihe cyerekana plastike.

Imiterere itandukanye ya Duplex idafite ibyuma: amasahani hamwe na kaburimbo yasukuye imiyoboro hamwe nimiyoboro itagira imiyoboro yo kurwara imiyoboro hamwe na flanges inkoni ninsinga

Duplex Icyuma kitagira ingaruka zirashobora kugabanywamo ibyiciro bine:

Imwe: Ubushumu buke, Uhagarariye UNSS32304, ibyuma ntabwo irimo Molybdenum, ibanziriza: 24-25, irashobora gusimbuza Aisi 304 cyangwa 316 ukurikije guhangayikishwa no guhangayika.

Babiri: Ubwoko bwo hagati bwa Alloy, urwego ruhagarariye UNSS31803, mbere: 32-33, kurwanya ruswa biri hagati ya Aisi316L na 6% kubyuma bidafite ishingiro.

Batatu: Ubwoko bwa Alloy, muri rusange burimo 25% birimo Molybdenum na azote, bamwe barimo kandi umuringa w'igitugu n'idubunzi, 38-39, kurwanya ruswa iri hejuru ya 22%.

Bane: Super Duplex Ubwoko bw'icyuma butagira ingano, birimo Molybdenum na azote, amanota menshi ni UNSS32750, hamwe no kurwanya ruswa, 40, ugereranije n'imitungo yuzuye, ugereranije na super austenitique. (Icyitonderwa: ITANGAZO: Gurwanya Agaciro kangana nagaciro)

Ibigize imiti ibijyanye na minini ya duplex ibyuma bya duplex ni cr, ni, mo na N. Muri bo, Cr na Mo bakoreshwa mu kongera ibintu bya Ferrite, mugihe ari ibintu bihamye. Impamyabumenyi imwe n'icyuma nayo ifite ibintu nka mn, cu, na w. cr, ni, na mo irashobora kunoza indwara ya ruswa. Kurwanya kwacyo no kwangiriza ruswa ni byiza cyane mubidukikije birimo ibidukikije.

Ibyiza bya Duplex idafite ibyuma

1. Ugereranije na atelitic ibyuma

1) Imbaraga zitanga umusaruro zirenze ebyiri zubuti busanzwe butoneye, kandi ifite plastike ihagije nuburemere busabwa kugirango bukore. Ubunini bwibikoresho byo kubika cyangwa ibikoresho byimiti bikozwe muri duplex idafite imyaka 30-50 munsi yibyo bikunze gukoresha ibyuma bikunze gukoresha ibyuma bidafite ingaruka, bifasha kugabanya ibiciro.

2) Ifite imbaraga nziza yo guhangayikishwa no kunyeganyega kwangwa, cyane cyane mubidukikije birimo chloride ion. Ndetse na duplex idafite ibyuma hamwe nibikoresho byo hasi cyane bifite uruhare runini muguhangayikishwa no guhungabanya imyanda kuruta ibyuma bidafite ishingiro. Stress BRORROSONION ni ikibazo gikomeye kuburyo ibyuma bidafite ibyuma bitunguranye biragoye kubikemura. 3) Kurwanya ruswa ya 2205 duplex yakozwe na baltainless yanduye ikoreshwa mu bitangazamakuru byinshi biruta ibyuma bisanzwe 316L bikabije, kandi SUPEX SUPNOX YATANZWE CYANE. Mu bitangazamakuru bimwe, nka acide ya acetike na aside ya marike, birashobora no gusimbuza hejuru-aluy ausonitic ibyuma bidafite ingaruka kandi ndetse na porloys-irwanya ruswa. 4) Ifite imbaraga nziza zo kurwanya ruswa. Ugereranije n'icyuma kidafite aho gifatika, ahinduranya kimwe, kwambara ibintu byangiza no kurwanira kunanirwa no kurwanya ibitero bya garingizo biruta ibyuma bidafite ishingiro. 5.

2. Ugereranije n'ibyuma

1) Imashini yuzuye ihanishi iruta ay'icyuma cy'umugati, cyane cyane uburemere bwa plastike. Ntabwo byunvikana ku buntu nk'urusitsi rwa Ferritic.

2) Usibye guhangayikishwa no kurwanya ruswa, ibindi kurwanya ruswa biruta ibyuma byifuro.

3) Gutunganya imikorere yubukonje nubukonje bukora neza nibyiza cyane kuruta ibyuma.

4) Imikorere yo gusudira ni nziza cyane kuruta ibyuma. Mubisanzwe, nta miterere isabwa mbere yo gusudira kandi nta bushyuhe bukenewe nyuma yo gusudira.

5) Urwego rusaba ni ruriya kuruta iyo ibyuma bituje.

Gusaba

Kubera imbaraga nyinshi za duplex steel, birashobora kuzigama ibikoresho, nko kugabanya urukuta rwumubiri. Fata Saf2205 na Saf2507w nkingero. Saf22055 irakwiriye gukoreshwa muri chlorine-irimo ibidukikije. Ibi bikoresho birakwiriye kumavuta cyangwa ibindi bitangazamakuru bitunganya bivanze na chloride. Saf22020 irakwiriye cyane cyane guhanahana ubushyuhe bukoresha chlorine-irimo ibisubizo bya akeque cyangwa amazi make yo gukonjesha. Ibi bikoresho birakwiriye kandi kubisubizo bya sulfuric yavanze acide hamwe na acide nziza hamwe nurugingo ruvanze. Kurugero: imiyoboro ya peteroli mu nganda za peteroli na gaze: Gufata amavuta yubukorikori mubyo ufatanije, sulfure birimo kwezwa gaze, ibikoresho byo kuvura amazi; sisitemu yo gukonjesha ukoresheje amazi yumunyu cyangwa ibisubizo birimo ibisubizo.
