S31803 Duplex Ibyuma bitagira umuyonga: Kurwanya ruswa irenze imbaraga nimbaraga nyinshi kubikorwa byinganda

S31803, izwi kandi nka Duplex 2205 cyangwa F60, ni urwego rwubahwa cyane rwa duplex idafite ibyuma ku isoko ryisi. Kumenyekana muri sisitemu ihuriweho na numero (UNS), ibi bikoresho byahawe agaciro kuberako birwanya ruswa idasanzwe, imbaraga za mashini zisumba izindi, hamwe nibikorwa bitandukanye mubidukikije.

Ibintu by'ingenzi bigize imiti n'imiterere

S31803 duplex idafite ibyuma biranga uruvange rwuzuye rwibintu bitanga ibintu byingenzi:

• Chromium (Cr):Hafi ya 22% - Yongera imbaraga zo kurwanya ruswa, cyane cyane kurwanya ruswa.

• Nickel (Ni):Hafi ya 5.0-6.0% - Itezimbere ubukana no guhindagurika.

• Molybdenum (Mo):Hafi ya 3.0% - Yongera imbaraga zo kurwanya ruswa, cyane cyane mubidukikije bikungahaye kuri chloride.

• Azote (N):Hafi ya 0.18% - Yongera imbaraga kandi igira uruhare mukurwanya ruswa.

Microstructure idasanzwe yibice bibiri, ihuza ibyiciro bya ferritic na austenitis, bivamo imiterere yubukanishi bwikubye kabiri ibyuma bisanzwe bya austenitike bitagira umuyonga mugihe bikomeza guhindagurika no gukomera.

Ibyiza Byiza ninyungu

Kurwanya Kurwanya Kurwanya

S31803 ntangarugero mukurwanya ubwoko butandukanye bwa ruswa, harimo:

• Gutobora no Gutobora:Chromium nini hamwe na molybdenum ibifasha gukora bidasanzwe mubidukikije bya chloride.

• Guhangayikishwa no Kwangirika:Imiterere ya duplex itanga imbaraga zo guhangana no gucika intege, nubwo bihura nibitangazamakuru bikaze.

Imbaraga Zikomeye

• Imbaraga Zirenze:Mubisanzwe, imbaraga zingana za S31803 zirenga 500 MPa, bigatuma biba byiza kubisabwa byumuvuduko mwinshi.

• Kunoza ubukana:Microstructure iringaniye ntabwo ishimangira imbaraga gusa ahubwo inashimangira gukomera no guhindagurika, bifite akamaro mubidukikije byinganda.

Weldability nziza

Mugihe hakenewe ubwitonzi budasanzwe mugihe cyo gusudira kugirango hirindwe kwangirika muri zone yibasiwe nubushyuhe, uburyo bukwiye bwo gusudira hamwe nubuvuzi bwa nyuma yo gusudira burashobora gutuma ingingo zikomeye, zitagira inenge. Ibi bituma S31803 ihitamo rifatika kubikorwa byo guhimba no gusana

Inganda

S31803 duplex idafite ibyuma isanga ikoreshwa cyane munganda zinyuranye bitewe nuburinganire bwuzuye bwimbaraga hamwe no kurwanya ruswa. Ibice by'ingenzi bisabwa birimo:

• Ibikoresho byo gutunganya imiti:Byiza kuri reaction, ibigega byo kubikamo, hamwe na sisitemu yo kuvoma aho bikenewe kurwanya imiti ikaze.

• Inganda za peteroli na gaze:Ikoreshwa cyane mumiyoboro, indangagaciro, hamwe na fitingi, cyane cyane mugihe cyumuvuduko mwinshi hamwe na chloride nyinshi.

• Ubwubatsi bwo mu nyanja no kubaka ubwato:Kurwanya kwangirika kwamazi yumunyu bituma bikwiranye ninyubako zo hanze, ibyuma byo mumazi, nibindi bikorwa byamazi.

• Ibikoresho bitanga ingufu:Gukoreshwa mu mashanyarazi n’ibikoresho bya kirimbuzi aho ubunyangamugayo bwimikorere nibikorwa byigihe kirekire ari ngombwa.

• Ibikoresho byubaka nubwubatsi:Kurangiza kwayo kuramba no kuramba byatumye ikoreshwa muburyo bwububiko bugezweho hamwe nuburyo bwiza

   

Kubahiriza amahame mpuzamahanga

S31803 duplex idafite ibyuma byujuje ubuziranenge mpuzamahanga mpuzamahanga ndetse nigihugu, byemeza ko byizewe kandi byiza. Urugero:

• ASME B16.11:Kugaragaza ikoreshwa ryayo mugukora sock weld hamwe nudupapuro twa pipe.

• ASTM A240 / A240M:Itanga umurongo ngenderwaho wibyuma bidafite ibyuma bikoreshwa mubikorwa bitandukanye.

• EN 10088-2:Ibisobanuro birambuye kubicuruzwa bitagira umwanda muburayi.

Uku gukurikiza amahame akomeye yemeza ko S31803 yujuje ibyifuzo byingirakamaro ku isi yose.

Umwanzuro

S31803 duplex ibyuma bitagira umuyonga bigaragara nkibintu byinshi kandi bikomeye bikenewe mubidukikije. Ihuriro ryiza cyane ryimbaraga nyinshi, kurwanya ruswa iruta iyindi, hamwe no gusudira kwizewe bituma ihitamo umwanya wambere mubice bitandukanye nko gutunganya imiti, peteroli na gaze, ubwubatsi bwo mu nyanja, kubyara ingufu, nubwubatsi. Mugihe inganda zikomeje gusunika imipaka yimikorere nigihe kirekire, S31803 ikomeje kuba ibikoresho byatoranijwe bitanga agaciro karambye numutekano.

Kubindi bisobanuro birambuye bya tekiniki hamwe nibisubizo byabigenewe, abanyamwuga barashishikarizwa kugisha amakuru yimibare no kuvugana nabatanga isoko bizewe.
