Umwirondoro w'ivyuma n'uruhara rw'inganda
Inconel 625, nayo izwi nka Nickel Alloy 625 canke UNS N06625, ni igikoresho gikomeye gikomeye gikomeye gikoreshwa n’umunyu gikomeye cane, gikoreshwa mu bikorwa aho ubushuhe n’ubushuhe bikomeye cane. Igumya inkomezi zidasanzwe, ubushobozi bwo guhangana n’ugukwegakwega, n’ugushikama kw’imitsi kuva mu bihe vy’ubukonje gushika ku bushuhe bwa degre 1000 (1832℃F).
Iryo shure rikoreshwa cane mu bikoresho vyo mu kiyaga, mu buryo bwo gutunganya imiti, mu bikoresho vyo kugenzura ubuhumane, mu bikoresho vy’imishwarara, no mu bikoresho vyo gusohora umwuka w’indege-aho ubutungane bw’imibumbe n’ugucungera ubuhumane bitegerezwa gukorana. Uburinganire bwayo bwa Ni-Cr-Mo-Nb buratuma haba igice c’umubiri civura kandi kigahagarika igitero co mu karere mbere no mu bihe vy’aside n’ivyuma vy’amazi.
Igishushanyo c'imiti n'ibiranga ivyuma
| Ikintu | % Ibipimo | Igikogwa |
|---|---|---|
| Nikeli (Ni) | Ikuruta canke ingana na 58,0. | Igishushanyo c'ishimikiro; gusenyuka n'ugushikama kw'ubushuhe |
| Koromu (Cr) | 20.0–23.0 | Ikora oxide idakora kugira ngo igenzure oxidation |
| Molibideni (Mo) | 8.0–10.0 | Irananira gusenyuka kw'ibinogo n'ibinogo |
| Niyobiyumu (Cb + Ta) | 3.15–4.15 | Ikomeza umuti ukomeye; ibuza guhinduka |
| Icuma (Fe) | Muto canke bingana na 5.0 | Kunoza ibiranga uguhingura |
| Karboni (C) | Muto canke bingana na 0,10 | Igenzura uguhingura carbide |
| Mn / Si / S | Muto canke bingana na 0.5 / 0.5 / 0.015 | Kubungabunga isuku n'uburyo bwo gusudira |
Ingaruka zihuriweko za molybdenum na niobium zitanga inkomezi nyinshi ata gukomera kw’imvura, bikaba vyemeza guhingura vyoroshe no gukora neza mu gihe kirekire-gushirwa mu bushuhe. Iyi microstructure igumya intete nziza kandi igakingira intete-urubibi rwo gusenyuka inyuma yo gusudira canke gutera.
Ukwizigirwa kw'ubuhinga mu gihe c'ubushuhe n'imibabaro
| Umutungo | Igipimo (iminota) | Umwami (min) | Imvugo |
|---|---|---|---|
| Inkomezi zo gukwega | 827 MPa | 120 ksi | Gukomeza ubunyankamugayo ku rugero rwa 870 |
| Inkomezi z'umwimbu (0,2 %) | 414 MPa | 60 ksi | Kunanira guhinduka mu gihe c'umuzigo |
| Ugukura | Irengeye canke ingana na 30 % | Irengeye canke ingana na 30 % | Ugukomera neza cane inyuma y'ugushirwa ahabona |
| Ubukomezi | Muto canke bingana na 95 HRB | Muto canke bingana na 95 HRB | Itanga ubushobozi bwo gukoreshwa n'imashini n'ubushobozi bwo guhingura |
Mu bihe vy’ibikorwa vy’ingendo, Inconel 625 igumya inkomezi z’urushe n’ugushikama kw’ingero n’ugutakaza guke mu kugenzura oxidation.
Uburyo bwo gukora n'uguvura n'ubushuhe
Amatiyo n’imiyoboro bihingurwa biciye mu gusohora bishushe canke gushushanya bikonje hanyuma bigaca bishirwa ku bushuhe bwa degre 1090–1150 (1995–2100℃F) hanyuma bikazimya vuba kugira ngo bisubire guhangana n’ugusenyuka. Ubwoko bw’amabuye y’agaciro bukorwa n’uburyo bwa TIG canke plasma munsi y’uburinzi bw’umuyagankuba udakora.
Guhingura neza no gupima uburebure bukonje bituma uruhome ruguma rumwe, mu gihe gutera ivyatsi no gutera ivyatsi bishasha bisubira gukora igipande co ku ruhande c’uruhome Cr2O3. Gukora no gusuzuma bihuye n'ASTM B444, B705, na B704ingingo mfatirwako.
Uguhangana n'ubumara mu binyamakuru vyose
Igikorwa kibiri c'ivyo bihimba -nickel-chromium oxide film ku bihe vy'ugutera oxidation n'ugukomeza kwa molybdenum-niobium kugabanya ibidukikije-bituma bigira ubushobozi bwo gukomera:
- Amazi y’ikiyaga n’amazi y’ikiyaga:Irwanya gusenyuka, gusenyuka, n'imibabaro-ugusenyuka kw'ugusenyuka.
- Asidi zitera umwuka (nitirike, chrome):Chromium irazigama ukuntu oxide ifatanye n’ubushuhe.
- Asidi zigabanya (amazi, fosifori):Molybdenum ibuza igitero co mu karere.
- Gazi isharira (H2S):Ishikamye ku bijanye n’ugusenyuka kw’imibabaro ya sulfide ku bijanye n’ibikorwa vy’amavuta na gazi.
- Ubushuhe bwinshi-buhinduka:Ishobora guhangana n'ugukura n'ugutakaza ivyuma kugera kuri degre 1000 .
Urutonde rw'ingero n'ugutanga ibicuruzwa
| Ubwoko | Inyuma y'umurongo | Uburebure bw'uruhome | Uburebure | Ibisobanuro |
|---|---|---|---|---|
| Umuyoboro udafise umugozi | 6-610 mm | 1-50 mm | Kugeza kuri m 12 | ASTM B444 / ASME SB444 |
| Umuyoboro w'amazi | 25-1200 mm | 1,5-60 mm | Kugeza kuri m 12 | ASME B705 / ASME SB705 |
| Tube (Igihindura Ubushuhe / Igikoresho) | 6-76 mm | 0.8-10 mm | Igipfukisho / Igororotse | ASME B704 / ASME SB704 |
Ivyiyumviro bikomeye-vy'ukwihangana biraboneka ku bikoresho n'ubushuhe-bihindura amakoraniro bisaba gushirwa neza no guheza ku ruhande.
Igerageza, Icemezo, n'Ukwizera Uburyo
Ibintu vyose birageragezwa kuASTM B829kubera ubutungane butagira -ubusenya n'ukuri kw'ingero.
Ivyo gusuzuma bimenyerewe birimwo isuzuma ry’amazi canke ry’amajwi, igenzura rya PMI ku bijanye n’ibirimwo nickel, n’igerageza ry’ugusenyuka kw’ibihimba vy’umubiri (ASTM G28 Method A/C).
Octal Pipe itanga ibikoresho n'RU 10204 3.1 / 3.2 MTC, gukurikirana neza, n'uburyo bwo gusuzuma ubw'uwundi muntu (BV, SGS, TUV).
Ishirwa mu ngiro ry'inganda n'ugushigikira umugambi
Inconel 625 ikoresha ibikorwa remezo bihambaye harimwo n’imiyoboro yo mu kiyaga mu mazi y’amazi y’umunyu w’amazi, ibihimba vy’umuyaga wo mu kirere, ubwato busubira gukora ibirwanisho vya kirimbuzi, ibikoresho vyo gukura umunyu, n’ibikoresho vyo gusukura ibihumanya.
Octal Pipe itanga inyishu z’ubuhinga zifise ubushobozi bwo gusudira, uguhuza ibikorwa vya NDE, n’inyandiko z’ubuhinga zigenewe imigambi ya EPC n’inguvu. Ubugenzuzi bw’imigenderanire budahinduka buratuma habaho ugusubiramwo kw’ubuhinga n’ugusenyuka mu gice cose c’ubushuhe.
IBIBAZO bibazwa
