316L - 316Ti - 316Hi Umuyoboro w'icyuma - BLOG

Ubushishozi

Yatejwe imbere kugirango ihangane n’imiti ikaze ,.Urukurikirane 316ibyuma bidafite ingese - bigizwe316L, 316H, na 316Ti- itanga imbaraga zidasanzwe zo kurwanya chloride na okiside.

Buri cyiciro gikora ubushyuhe butandukanye cyangwa ibihimbano, bitanga injeniyeri guhinduka mumashanyarazi, sisitemu y'amashanyarazi, hamwe nibidukikije byo mu nyanja.

316L:Hasi - variant ya karubone igabanya imvura ya karbide mugihe cyo gusudira.
316H:Urwego rwo hejuru - urwego rwa karubone rwashyizwe hejuru kurwego rwo hejuru - imbaraga zubushyuhe hamwe no guhangana n’ibikurura.
316Ti:Titanium - verisiyo itajenjetse yongerera ingirabuzimafatizo hagati yubushyuhe bwa serivisi.

Igishushanyo mbonera hamwe nimyitwarire ya ruswa

Amavuta18% chromium na 12% nikelumusingi ukora imiterere ihamye ya austenitis, mugihemolybdenum (~ 2.0–3.0%)byongera cyane pitingi na crevice kurwanya ruswa muri chloride - itangazamakuru.

Titanium cyangwa igenzurwa rya karubone itanga imikorere idahwitse - haba mumashanyarazi ya kirogenike cyangwa inteko zidasanzwe.

Ibyiza bya metallurgiki:

Kurwanya bihebuje kurwanya acide, fosifori, na acide sulfurike
Ubudahangarwa bukabije kuri chloride - butera guhangayika
Firime ihamye ya firime igera kuri dogere 870 (dogere 1600 F)
Ubudasanzwe bugaragara weld hamwe nibibazo bike byo gukangurira

Ibigize imiti (kuri ASTM A312 / A213 / A269)

Uburyo bwo kureba:

316L nibyiza kubiterane byo gusudira hamwe numuyoboro wa kirogenike; 316H na 316Ti bihebuje mubihe bikomeza ubushyuhe - hamwe nubushyuhe bwimikorere.

Inzira yo gukora no guhimba

Gukora imiyoboro 316 yuruhererekane idafite ibyuma bisaba kugenzura neza ibyuma bya metallurgji kugirango ibungabunge ruswa kandi ihure.

Bitandukanye nicyuma cya karubone, ayo mavuta ya austenitike arasaba ibidukikije bishonga neza, kugenzura ubushyuhe bukabije, no kugenzura ubukonje kugirango birinde ubukangurambaga cyangwa guhunika ingano.

Umusaruro usanzwe:

Vacuum cyangwa Argon Furnace Gushonga:Itunganya chimie ya aliyumu kandi igabanya azote cyangwa sulfure.
Gutobora Bishyushye no Kurambura:Hindura fagitire zikomeye mu mwobo utagira ingano hamwe n’intete zerekeza ku kwihanganira umuvuduko mwinshi.
Igishushanyo gikonje n'ubunini:Kugera ku kwihanganira neza, kunonosora ibitekerezo, no kuzamura ubuso bwiza.
Igisubizo Annealing:Ikorwa hagati ya dogere 1040 na dogere 1120, hagakurikiraho amazi yihuse cyangwa kuzimya ikirere kugirango ushonga karbide kandi igarure ruswa yuzuye ya ruswa.
Gutoranya no gutambuka:Kuraho oxyde kandi igarura chromium - firime ikungahaye cyane ya passiyo ikomeye kugirango irambe muri acide cyangwa chloride - ibidukikije bikungahaye.

Imiyoboro isudira ihimbwa ukoreshejeGTAW (TIG)cyangwagusudirahamwe nibikoresho byuzuza bihuye nibigize shingiro (ER316L cyangwa ER316Ti).

Kohereza - gusudira igisubizo hamwe no gusya birashobora gukoreshwa kugirango ugarure ruswa mu bikorwa bigoye nka sisitemu yo kuvura imiti n’imiti.

Kwipimisha no Kugenzura Ubuziranenge

Igenzura ryuzuye ryemeza ko buri 316 - urukurikirane rwumuyoboro wibyuma bitagira umuyonga bigumana ituze ryumuriro kandi ntirishobora kumeneka mbere yo kubyara.

Uburyo bwo kwipimisha burahuyeASTM A312, A999, kandi bihuyeASME SAibisobanuro, bikubiyemo ibyangiza kandi bitari - ibyiciro byo kugenzura.

Kugenzura ubuziranenge busanzwe:

Hydrostatike cyangwa Eddy {{0} Test Ikizamini kigezweho:Yemeza ubunyangamugayo bwimbere kandi ikamenya guhagarara hejuru.
Ibizamini bya Tensile, Gukomera, no Kuringaniza:Kwemeza guhuza imashini muburyo bwo gukora.
Ikizamini cyo Kwangirika hagati (ASTM A262 Imyitozo E):Kugenzura ubudahangarwa bwimvura ya karbide, cyane cyane kuri 316L na 316Ti.
Kumenyekanisha Ibikoresho byiza (PMI):Iremeza ko alloy yubahiriza nomero Cr - Ni - Mo ibirimo.
Kugenzura Amashusho n'Ibipimo:Gupima kugororoka, kurangiza kurangiza, hamwe nurukuta hamwe nugupima neza.

Kuri hejuru - ubuziranenge cyangwa inzira - porogaramu zikomeye, birashobokaisesengura rya ferrite, kwipimisha radiografi, cyangwaisuzumabumenyi ryo hejuru (Ra Ntibisanzwe cyangwa bingana na 0.8 μ m)birashobora gutomorwa.

Amakuru yikizamini yose yanditswe munsi ya QA igenzurwa kandi yatanzwe nkukoEN 10204 3.1 / 3.2 ibyemezoKuri Byuzuye.

Imikorere muri serivisi

316L, 316H, na 316Ti buriwese yerekana kwihangana kudasanzwe mukibazo cyibikorwa:

316L:Indashyikirwa mu gusudira - ibikoresho biremereye, kugabanya imvura igwa.
316H:Irwanya kunyerera no guturika munsi yumuriro muremure.
316Ti:Igumana guhindagurika no kurinda ruswa nubwo nyuma yubushyuhe bwinshi.

Igice cya oxyde ihamye hamwe nubushobozi buke butuma bikwiranye byombiibiryo - urwegonasisitemu yo gutunganya imiti.

Porogaramu

Guhindura ubushyuhe bwa peteroli na kondenser tubing
Imirongo itunganya imiti nibiribwa
Ibikoresho byo kumena impapuro
Offshore platform hamwe na sisitemu yo gusohora marine
Hejuru - ubushyuhe bwo kugarura ubushyuhe na flue - sisitemu ya gaze
Ubwinshi bwumuryango 316 butanga serivisi zizewe mu nganda zisaba kwangirika no kwihanganira ubushyuhe.

Gutanga Ubwubatsi no Gukurikirana

Nkigice cyacyo kitagira umwanda - ibyuma byicyuma,Umuyoboro wa Octalitanga imiyoboro ya 316L, 316H, na 316Ti ifite ibisobanuro byuzuye, ibyemezo by'urusyo (EN 10204 3.1 / 3.2), hamwe no kugenzura NDE.

Buri cyiciro gikorerwa munsi ya ISO - inzira igenzurwa, ikemeza kubahiriza code ya ASTM na ASME kubikorwa byinganda nu mushinga - urwego rusaba.
