Umwirondoro wa Alloy hamwe ninshingano zinganda
Inconel 625, izwi kandi nka Nickel Alloy 625 cyangwa UNS N06625, ni igisubizo gikomeye - igisubizo - gishimangira nikel - chromium - molybdenum - niobium ivanze ryakozwe mubikorwa aho ruswa nubushuhe bukabije bibana. Ikomeza imbaraga zidasanzwe, irwanya ibinyabuzima, hamwe na okiside ituruka kumiterere ya kirogenike igera kuri dogere 1000 (dogere 1832 F).
Uru rwego rukoreshwa cyane mubikoresho byo mu nyanja, sisitemu yo gutunganya imiti, ishami rishinzwe kurwanya umwanda, ibyuma bya kirimbuzi, hamwe n’iteraniro rya moteri y’indege - aho usanga uburinganire bw’imiterere no kurwanya ruswa bigomba gukorera hamwe. Ni - Cr {{3} Mo
Igishushanyo cya Shimi na Metallurgical Ibiranga
| Ikintu | Urwego | Imikorere |
|---|---|---|
| Nickel (Ni) | Birarenze cyangwa bingana na 58.0 | Matrix ishingiro; ruswa hamwe nubushyuhe bwumuriro |
| Chromium (Cr) | 20.0–23.0 | Gukora paside ya oxyde yo kugenzura okiside |
| Molybdenum (Mo) | 8.0–10.0 | Irwanya gutobora no kwangirika |
| Niobium (Cb + Ta) | 3.15–4.15 | Gushimangira igisubizo gihamye; Irinda guhindagurika |
| Icyuma (Fe) | Ntibiri munsi cyangwa bingana na 5.0 | Kunoza ibiranga guhimba |
| Carbone (C) | Ntibiri munsi cyangwa bingana na 0.10 | Igenzura imiterere ya karbide |
| Mn / Si / S. | Ntibiri munsi cyangwa bingana na 0.5 / 0.5 / 0.015 | Komeza kugira isuku nubwiza bwa weld |
Ingaruka zifatika za molybdenum na niobium zitanga imbaraga nyinshi nta mvura iguye, bigatuma guhimba byoroshye no gukora neza mugihe kirekire - igihe cyo guhura nubushyuhe. Iyi microstructure igumana ibinyampeke byiza kandi ikabuza ingano - kwinjiza imbibi nyuma yo gusudira cyangwa gufunga.
Imashini yizewe munsi yubushyuhe na Stress
| Umutungo | Ibipimo (min) | Imperial (min) | Ibisobanuro |
|---|---|---|---|
| Imbaraga | 827 MPa | 120 ksi | Igumana ubunyangamugayo kugeza kuri dogere 870 |
| Imbaraga Zitanga (0.2%) | 414 MPa | 60 ksi | Irwanya guhindagurika munsi yumutwaro |
| Kurambura | Kurenza cyangwa bingana na 30% | Kurenza cyangwa bingana na 30% | Inyandiko nziza zidasanzwe - kwerekana |
| Gukomera | Ntibiri cyangwa bingana na 95 HRB | Ntibiri cyangwa bingana na 95 HRB | Itanga imashini kandi ikora |
Mubihe bya serivise ya cycle, Inconel 625 igumana imbaraga zumunaniro hamwe nigihagararo gihamye hamwe nigihombo gito mukugenzura okiside.
Uburyo bwo gukora no kuvura ubushyuhe
Imiyoboro hamwe nigituba bikozwe muburyo bushyushye cyangwa gushushanya ubukonje hanyuma igisubizo kikaba gishyizwe kuri dogere 1090–1150 (dogere 1995–2100 dogere F) hagakurikiraho kuzimya vuba kugirango bigarure ruswa. Ubwoko bwo gusudira bukorwa na TIG cyangwa plasma murwego rwo gukingira gaz inert.
Gukora neza hamwe nubunini bukonje bikomeza uburinganire bwurukuta, mugihe gutoragura no kumurika neza byongera gukora firime ikingira Cr₂O₃. Gukora no kugenzura byubahirizaASTM B444, B705, na B704ibipimo.
Kurwanya Ruswa Kurwanya Itangazamakuru
Amavuta abiri ya alloy - nikel - firime ya chromium oxyde ya okiside hamwe na molybdenum - niobium ishimangira kugabanya ibidukikije - itanga imiti ihamye yimiti:
- Amazi yo mu nyanja na chloride:Irwanya gutobora, gutobora, no guhangayika - guturika.
- Oxidizing acide (nitric, chromic):Chromium irinda okiside yubushyuhe.
- Kugabanya aside (hydrochloric, fosifori):Molybdenum irinda igitero cyaho.
- Gazi isukuye (H₂S):Ihangane na sulfide ihangayikishijwe na serivisi ya peteroli na gaze.
- Hejuru - okiside yubushyuhe:Kurwanya gupima no gutakaza ibyuma kugeza kuri dogere 1000.
Urwego ruringaniye hamwe no gutanga ibicuruzwa
| Andika | Hanze ya Diameter | Uburebure bw'urukuta | Uburebure | Ibisobanuro |
|---|---|---|---|---|
| Umuyoboro utagira ikizinga | Mm 6-610 mm | 1-50 mm | Kugera kuri m 12 | ASTM B444 / ASME SB444 |
| Umuyoboro wo gusudira | Mm 25–1200 | 1,5-60 mm | Kugera kuri m 12 | ASTM B705 / ASME SB705 |
| Tube (Ubushyuhe bushya / Igikoresho) | Mm 6-76 | 0.8-10 mm | Igiceri / Igororotse | ASTM B704 / ASME SB704 |
Kurangiza - kwihanganira birahari kubikoresho nubushyuhe - inteko zungurana ibitekerezo zisaba guhuza neza no kurangiza neza.
Kwipimisha, Kwemeza, hamwe nubwishingizi bufite ireme
Ibicuruzwa byose bipimwa kuriASTM B829kubitari - ubunyangamugayo bwangiza kandi bwuzuye.
Igenzura rya buri murongo ririmo ibizamini bya hydrostatike cyangwa ultrasonic, kugenzura PMI kubirimo nikel, no gupima ruswa hagati (ASTM G28 Method A / C).
Umuyoboro wa Octal utanga ibikoresho hamweEN 10204 3.1 / 3.2 MTC, ibisobanuro byuzuye, na gatatu - amahitamo yo kugenzura amashyaka (BV, SGS, TUV).
Gushyira mu bikorwa inganda no gutera inkunga umushinga
Inconel 625 ikora ibikorwa remezo bikomeye birimo imiyoboro yo mu nyanja ya chloride, ibikoresho byo mu kirere biva mu kirere, ubwato butunganya ingufu za kirimbuzi, inganda zangiza, hamwe na scrubbers zo kurwanya umwanda.
Umuyoboro wa Octal utanga ibisubizo byubushakashatsi bufite impamyabumenyi yo gusudira, guhuza NDE, hamwe nibyangombwa bya tekiniki bigenewe EPC n'imishinga y'ingufu. Igenzura rihoraho ryerekana imikorere yubukorikori hamwe na ruswa muri buri cyiciro cyubushyuhe.
Ibibazo
Q1: Ni ubuhe buryo ngomba kwerekana kuri Alloy 625 pipe vs tube?
Q2: UNS N06625 (Alloy 625) irashobora gukoreshwa muri serivisi isharira (H2S)?
