Gusudira Gupfuka Flange

A Gusudira gupfuka flangeni flange icuzwe n’ivyuma bishobora guhangana n’ugusenyuka-bishizwe ku ruhande rw’amazi-rukorana n’ugusudira. Igipande c’ishimikiro gitwara umuzigo w’umuvuduko n’inguvu z’ugutera, mu gihe igice c’imbere ca CRA kirinda ivyuma, mu maso hakingira, umurongo wa RTJ, umurongo w’izosi, canke ibindi bibanza bitose ku bimenyeshamakuru bishobora gusenyuka.

Ivyo bikoresho bikoreshwa iyo icuma c’umuyagankuba canke icuma c’umuyagankuba gitoyi gifise inkomezi zihagije z’ubuhinga, ariko uruhande rw’ubuhinga rusaba ko rushobora guhangana n’ugusenyuka. Ivyerekeye ibikorwa bimenyerewe ni gazi isharira, gazi irimwo CO2{1}}, gutera amazi yo mu kiyaga, amazi akomoka, amazi afise kloride-, ibikoresho vyo gusukura, imirongo y’ibikorwa vy’ubuhinga bwa peteroli, n’uguhuza imiyoboro yo mu kiyaga.

Ugereranije n’ivyuma bikomeye vy’ivyuma, gupfuka ivyuma bishobora gutuma umugambi ukoresha ivyuma bishobora gusenyuka-ku butaka busabwa gusa. Ivyo bifasha kugenzura igiciro c’ibikoresho mu gihe umubiri w’ibarabara uguma ukomeye bihagije ku bijanye n’umugwi w’umukazo usabwa. Ivyuma vy'umunanigusudira gupfuka amabuye y'agaciromu ijosi ry'ivyuma, impumyi, RTJ, gunyerera-ku, n'ubwoko bushingiye ku gishushanyo-, harimwoIvyuma 625 / Inconel 625 Gusudira Gupfuka Igipfukisho, Alloy 825, 316L, 904L, ivyuma bibiri bitagira ibara, n’ivyuma bibiri vy’ivyuma bitagira ibara vy’agaciro kanini.

Igipfukisho c’ivyuma cubatswe n’ibikoresho bibiri. Igikoresho co gucukura gitanga inkomezi z’ubuhinga, igipimo c’umuvuduko, uburebure bw’ibarabara, n’ugushikama kw’amabuye. Ivyo bikoresho vy’ugupfuka biratanga ubushobozi bwo guhangana n’ugusenyuka ku ruhande rwo gutonyanga.

Ivyo bikoresho vy’ishimikiro rusangi birimwo ASTM A105 ku bikoresho vy’ivyuma vy’ivyuma, A350 LF2 ku bikoresho vy’ubushuhe buke, A694 F52 / F60 / F65 / F70 ku bikoresho vy’ugutanga umuvuduko munini, na A182 ku vyuma vy’ivyuma, ivyuma bitagira ibara, ivyuma bitagira ibara.

Igikoresho co gupfuka CRA gikwiye gutorwa hakurikijwe uburyo nyabwo bwo gukora. Igiciro conyene si co gituma umuntu ahitamwo neza. H2S, CO2, ivyiyumviro vya chloride, ubushuhe bwo gukoresha, umuvuduko, amazi arimwo, pH, kwinjira kw’umwuka w’ikirere, n’ibikoresho vy’imiyoboro bihuye vyose birashobora kugira ico bikoze ku guhitamwo ibikoresho vya nyuma.

Kuberaflange gupfuka gusudira gupfukaimigambi, ivyuma vy’ugupfuka na vyo nyene bikwiye guhura n’igice gifatanye. Iyo flange ifatanye n’umuyoboro w’ivyuma, umuyoboro w’umurongo wa CRA{1}}, umuyoboro w’ivyuma, umuyoboro w’ivyuma ushobora guhangana n’ugusenyuka, umugozi w’ivyuma, canke umuyoboro w’ivyuma, urubibi rw’ivyuma bipfutse rukwiye gusubirwamwo kugira ngo icuma ca carbone kitarinzwe ntikiboneke mu nzira y’amazi.

Aho hantu hapfutse si ikintu gitoyi. Ifata ingingo y’igiciro, amahera yo gukoresha imashini, urugero rwo gusuzuma, be n’uko iyo flange ishobora vy’ukuri gukingira ahantu hatose. Ikete ry'ugugura rivuga ngo "CRA overlay irakenewe" akenshi ntirihagije. Ico gishushanyo gikwiye kwerekana neza aho igice co gupfuka ivyuma gikenewe.

RTJ weld gupfuka flanges bisaba kwitwararika cane. Igipfukisho c’impeta ni ikibanza co gukingira, si igicapo c’imashini gusa. Inyuma yo gupfuka n’ugukoresha imashini ya nyuma, umurongo ukwiye gusuzumwa kugira ngo umenye uburebure, uko ubuso buri, igisubizo ca PT, n’uburemere busigaye bw’ugupfuka.

Ku bijanye na flanges z’imbere ziduzwe, ahantu h’ugukorana n’igipfukisho hakwiye kugenzurwa inyuma y’uguhangana kwa nyuma. Igipande ca CRA kigaragara neza ntikihagije iyo uburinganire bw’isura y’ikidodo, iherezo canke uburemere inyuma yo gukoreshwa n’imashini bidahuye n’ibisabwa vyo gushushanya.

Ivyo guhinguragusudira gupfuka amabuye y'agacironi itandukanye n’ugukoresha imashini zisanzwe z’amaflanje. Ivyo bitegerezwa gufatwa nk’ivy’ugusudira, ivy’ugukoresha imashini, ivy’ubuhinga bwa nyuma, n’ivy’ugukingira ahantu igihe kimwe.

Inzira y’uguhingura ikora mu bisanzwe irimwo intambwe zikurikira:

1. Isubiramwo ry'ishingiro

2. Gupfuka-akarere n'ivyemezo vy'amashini
Igipfunsi, mu maso haduze, umurongo wa RTJ, mu maso h’imbere hahumye, uguhinduka kw’izosi, canke ibindi bice vy’amazi birasubirwamwo ku gishushanyo. Ivyuma bihagije vyo gukoresha imashini bitegerezwa gutegurwa kugira ngo igice ca nyuma gikozwe n’imashini kigumye gifise igice ca CRA gikenewe.

3. WPS / PQR n'ugutegura ivyuma vy'ukuzuza
Uburyo bwo gusudira, ivyuma vy’ukuzuza, uburyo bwo gusudira, urugero rw’ubushuhe, urutonde rw’ibice, n’ubushobozi bwo gusudira bikwiye gutegurwa imbere y’uko bikorwa. Ivyo birahambaye canecane ku bikorwa vyo gutera ivyatsi 625, 825, ivyumba bibiri, n’ivyumba bibiri vyinshi.

4. CRA gupfuka gupfuka
Igipande ca CRA gishirwa n’abasudira canke abasudira bafise ubushobozi. Multi-layer overlay ikoreshwa kenshi kubera ko igice ca mbere gishobora gusenyuka n'icuma c'ishimikiro. Ukwemera kwa nyuma gukwiye gushingira ku ruhande rwarangije gukoreshwa n’imashini.

5. Gusukura hagati no kugenzura amaso
Gusukura hagati y’ibibanza bicako birafasha kwirinda ivyuma, ubuhumane, ukubura ivyuma bifatanye, n’utunenge two ku ruhande. Iyo ntambwe si igikorwa co gushaza; akenshi rifata ingingo nimba mu nyuma isuzuma rya PT rizoca risukuye.

6. Gusubiramwo PWHT iyo bisabwe
Ibikoresho bimwe bimwe vy'ishimikiro canke ibisobanuro vy'umugambi bishobora gusaba gukoreshwa ubushuhe inyuma y'ugusudira. PWHT ikwiye gusubirwamwo imbere y’uko ikorwa kuko ishobora kugira ico ikoze ku gukomera, ku kugenzura ingero, no ku mugambi wa nyuma wo gusuzuma.

7. Gukoresha imashini zikomeye n'ugukora imashini za nyuma
Inyuma y’ugusudira, flange irakoreshwa n’imashini kugira ngo igere ku mfuruka y’iherezo, imbere, RTJ groove, umwobo w’amabuye, n’ingero z’ugukingira. Aho ni ho uguhingura ataco witaho bishobora gukuraho ibikoresho vyinshi cane vya CRA. Igitigiri c’ibintu bipfutse biheze gitoyi cane gikwiye kugumaho inyuma y’iyi ntambwe.

8. Gusuzuma kwa nyuma no gusubiramwo inyandiko
PT, PMI, ubukomezi, ferrite, isuzuma ry’ingero, n’isuzuma ry’iherezo ry’imbere bikorwa hakurikijwe ibisabwa n’umugambi. Raporo zikwiye guhuzwa n’ikimenyetso c’ibarabara, inomero y’ubushuhe, n’urutonde rw’ibintu vyo gupakira imbere y’uko zirungikwa.

Kugira ngo ubone insobanuro yagutse y’ubuhinga bwo gupfuka ibikoresho vy’imiyoboro, ivy’amabarabara n’ivy’amasahani, raba ivyacuUburongozi bwo gusudira.

Ku bipande vy’ivyuma vy’ivyuma, isuzuma ritegerezwa kwemeza ibintu bibiri: ivyuma vy’ishimikiro bihuye n’ibisabwa vy’ubuhinga n’ingero, kandi ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma. Iyo uruhande rumwe rumwe rugoyagoya, iyo flange ishobora kunanirwa kwemerwa n’umugambi.

PMI inyuma yo gukoresha imashinini ikintu gihambaye cane. Iyo PMI ikorwa gusa imbere y’uko ikoreshwa n’imashini, ishobora kutagaragaza neza uburebure buzokorana n’ivyo bikoresho. Ku bijanye n’igikorwa co gutwara umunyu canke chloride-, ahantu ha nyuma hakozwe n’imashini ni ho hahambaye cane.

Ku vyoherezwa hanze, guhuza inyandiko ni kimwe mu vyo kugenzura uburyo. Igitigiri c’ubushuhe, icemeza ko ibikoresho vy’ishimikiro, ivyuma vy’ivyuma, raporo ya PMI, raporo ya PT, urutonde rw’ibintu vyo gupakira, n’ikimenyetso c’inyuma bikwiye gufatanya neza. Ivyo bigabanya ingorane zo kwakira igihe co gusuzuma bitewe n’uko amakuru abuze canke adahuye.

Ivyo bikoresho bikoreshwa aho umubiri w’ivyo bikoresho ukeneye inkomezi z’umuvuduko usanzwe, ariko amazi{0}}aho akora ategerezwa kunanira uburozi buva ku gazi y’umunyu, amazi afise kloride-, amazi yo mu kiyaga, amazi y’aside canke amazi y’ibikorwa vy’ubukazi. Bitandukanye n'ibisanzwegusudira kuri flangen’ugutoranya ahanini ku bijanye n’uguhuza imiyoboro n’umugwi w’inguvu, ivyuma vy’ugupfuka bitegerezwa kandi kugenzura ubuso bwa CRA bugaragazwa n’ivyo bikoresho.

• Uburyo bwo gukora gazi ikarishe no kuyikorakoranya

Mu H2S-irimwo igikorwa, umubiri w’ibarabara ushobora gusaba icuma ca carbone canke icuma c’agaciro gatoyi, mu gihe ahantu hatose hakeneye uburinzi bwa CRA. Alloy 625 overlay ni ikintu gisanzwe gisubirwamwo ku bw’ubwo bwoko bw’igikorwa. Ivy’ugucungera uburemere, uko HAZ imeze, n’ibisabwa vya NACE MR0175 / ISO 15156 bikwiye gusuzumwa imbere y’uko bikorwa.
