CRA yambaye umuyoboro

Insobanuro y'umuyoboro wambaye:umuyoboro w’icuma ca carbone-ufise igice c’ivyuma gishobora guhangana n’ugusenyuka (CRA) gifatanye n’ivyuma ku ruhande rw’imbere (kipfutse), canke umuyoboro wa CRA utandukanye ushizwe imbere mu muyoboro w’icuma ca carbone- (ufise umurongo). Intumbero ni ugutuma CRA iguma ishobora guhangana n’ugusenyuka aho amazi akora, mu gihe igumya inkomezi n’imiterere y’igiciro c’ivyuma bitwara carbone-.

Mu gutwara amavuta, gazi, n'imiti, ugusenyuka si ikibazo co gusanasana gusa-bisobanura ubuzima bw'urutonde rwose. Amatiyo y’ivyuma vy’umuyagankuba, naho akomeye mu vy’ubuhinga, arasenyuka ningoga iyo akoresheje gazi y’umunyu canke amazi y’ikiyaga. Ku rundi ruhande, gukoresha imiyoboro ikomeye y’ivyuma bishobora guhangana n’ugusenyuka (CRA) ni vyiza cane mu vy’ubuhinga ariko ntibishobora gutuma ubutunzi bugumaho.

Kugira ngo abahinga bashobore gukuraho ico kinogo, barateguye .CRA yambaye kandi ifise umurongo, umuti w’ivyuma uteye imbere ufatanya .inkomezi, ukudashobora gusenyuka, n'igiciro-ubushobozimu kintu kimwe cakozwe n’abahinga.

Amahitamwo y'ibikoresho vy'imiyoboro (Ishingiro + CRA Layer)

Mu ntumbero yayo, umuyoboro wa CRA Claded niumuyoboro w'ivyuma bibiri, bihuza ivyuma bibiri bifise uruhara rutandukanye ariko bifashanya:

Igipande c'imiterere (Igipfukisho co hanze):Ivyuma vy’agaciro kanini canke vy’agaciro gato (nk’akarorero, API 5L X60/X65, ASTM A106, A333) bitanga ubushobozi bwo kwikorera umuzigo w’ubuhinga.

Intambamyi y'Ugusenyuka (Igice c'Imbere):Ivyuma bishingiye kuri nickel canke bitagira ibara nk’ivya 316L, Inconel 625, Ivyuma 825, canke Duplex 2205 bikora igipfukisho gikomeye co gukingira CO2, H2S, n’amazi afise chloride.

Ukwo gukorana kw’ivyuma kurashika ku co ata n’imwe muri izo cuma yari gushobora gushikako yonyene: umuyoboro ushobora kwihanganira umukazo mwinshi cane, ubushuhe, n’ibitero vy’ubumara mu myaka mirongo, mbere no mu bibanza vyo munsi y’ikiyaga canke vy’umunyu mwinshi-.

Mu buryo butandukanye n’ivyuma bisanzwe vy’umuyagankuba, imiyoboro ya CRA cald isaba ko haba ugufatanya neza hagati y’ivyuma vy’umuyagankuba n’ivyuma vy’umuyagankuba. Uburyo bukoreshwa buvana n’ibisabwa vyo gukora n’uburemere bw’ibikorwa:

Inzira yose ikurikirwa n’Ubushuhe buvugwa, igerageza ry'ijwi ry'imbere, n'isuzuma ry'imberekugira ngo bagenzure ugushikama kw’ivyuma n’ugupfuka kwa CRA guhoraho.

Amahuza y'itongo n'Ivyiyumviro vyo gukora

Gusudira amatiyoni ahanini ku bijanye no kurinda uruzitiro rwa CRA ku nzira y’ugusudira-kuko ugusenyuka, ubushuhe bwo kwinjiza, n’ugutegura iherezo ry’ugusudira bifata ingingo nimba ubushobozi bwo guhangana n’ugusenyuka buzigama inyuma y’ugusudira-in. Abaguzi bakunda kuvuga ubwoko bw’ivyuma (girth weld / tie-in spool), ibisabwa vyo gutegura iherezo ry’ivyuma, n’urugero rw’isuzuma kugira ngo uguhingura ibintu vyo mu mazi ntibihagarare kugira ngo bisubire gukorwa.

Hari RFQs zandika ibi ngo .gusudira imiyoboro; ivy’ugucungera ni bimwe: gucungera ukuntu CRA igaragara ku nzira y’ugusudira, gukoresha ibikoresho bihuye, no kwemeza uko CRA iri ku ruhande rw’ugusudira.

• Gutegura iherezo ry'ugusudira:Sigura bevel + CRA edge ubuvuzi kugira ngo tie-in ntiyigabanye CRA ataco yiteze.
• Ubushuhe bwinjira n'ubugenzuzi bw'ugusenyuka:Gumana CRA chemistry ku ruhande rw'ivyuma kugira ngo wirinde "gusa neza, gusenyuka mu nyuma".
• Igenzura ryibandako:Gusaba NDT/PMI scope ku bibanza vy’ugusudira iyo umugambi wo kwemera umugambi ubisaba.

Ku bijanye n'umuyoboro wa CRA, "clad" na "lined" si amajambo yo kugura ashobora guhindurwa. Ihitamwo ryiza rivana n’ibishobora gutera nabi mu guhingura no mu gufatanya (ugushirwa ahabona kwa CRA ku mpera z’ivyuma, ukugenda kw’ivyuma, ubutungane bw’ivyuma), n’ico umugambi ukeneye kwemeza mu kwakira. Octal Pipe ikoresha urutonde ruri musi kugira ngo RFQs zigume zigereranywa no kwirinda guhagarika-inzira y'inyuma ku rwego rw'ibarabara.

Ivyuma vya CRA bitorwa hakurikijwe uburyo bwo gusenyuka be n’ubuhinga bwo gukora. Imiterere isanzwe irimwo:

Ivyo bihuriro bituma .ubutungane bw'ivyuma n'uburinzi bw'ubumarabirashikwako icarimwe-ata muzigo w’amahera y’ubwubatsi bwa CRA bushitse.

A Umuyoboro wa CRAumuti usanzwe ugaragazwa igihe icuma ca carbone conyene kidashobora kwihanganira amazi akomoka mu buzima bw’umugambi, ariko umuyoboro wuzuye ukomeye wa CRA ntaco umaze. Ivyo bishobora gutuma habaho ingorane zo gusenyuka kw’umuyagankuba CO2, ivyerekeye ibikorwa vy’umunyu, gukoresha amazi menshi -kloride, n’imirongo y’amazi yo mu kiyaga aho uburyo bwo gusanura ari buke. Muri ivyo bihe, intumbero y'ugutanga amasoko si "CRA hose," ahubwo ni ahantu hatose CRA hagenzurwa harimwo ibimenyamenya vy'ugusudira n'ugusuzuma bishobora gutegekanirwa.

CRA Clad Pipes zishirwa kw’isi yose mu bidukikije aho ingorane zo gusenyuka n’ivyo imibumbe ikeneye bihurira:

• Imirongo y'amazi maremare n'amazi yo munsi y'ikiyagagutwara amazi y'inzira nyinshi
• Urushinge rwa CO2 n'uburyo bwo gukira
• Amahinguriro yo gusubira gutera amazi yo mu kiyaga no kuyakuramwo umunyu
• Ivyumba vy'isuku n'ivy'amavuta ya peteroligutunganya aside canke kloride
• Inganda z'amashanyarazi n'ivy'imitimunsi y'ubushuhe bwinshi n'ingendo z'umuvuduko

Na CRA ubutungane bwagenzuwe munsi yaNACE MR0175 / ISO 15156kandiAPI 5LD, iyo miyoboro ishobora gukora imyaka 20–30 ataco ikora.

Ku baguzi bagereranyaabahinguzi b'imiyoboron'umuntu afise ubushoboziumucuruzi w'imiyoboro yambaye, Octal Pipe's inyungu yerekanwa mu gutanga ibisobanuro bikunda gutuma umugambi ufata: dufunga inzira y'ubwubatsi bwa clad/liner ku RFQ, tugenzura weld-iherezo ry'ukwitegura kugira ngo amajosi y'umurima ntagaragaze canke ngo yononekare igice ca CRA, kandi tugakomeza gukurikirana bikomeye ku {con}d igikoresho ca CRA {con}d kwakira. Mu vy’ukuri, ivyo bisigura ko igicuruzwa gishikirizwa n’ibimenyetso vy’imiyoboro bihuye, ikimenyetso c’urugero rw’imiyoboro gitomoye, n’inyandiko zihuza imiyoboro y’ishimikiro n’urugero rwa CRA ku rutonde rumwe rw’ibirungikwa-ku buryo amashirahamwe y’abahinguzi adahatirwa gukora igikorwa co gusubira kumenya imbere yo gusudira.

• Ivyumba bibiri -birinda CO2, H2S, na kloride
• Igihe kirekire-inkomezi z'imibumbe n'igiciro ca CRA kigabanutse
• Ihuye n'ugusudira n'ugushiraho imiyoboro isanzwe
• Ni vyiza ku mazi maremare, HPHT, n'imiyoboro y'amazi y'umunyu
• Yemejwe na API, ASTM, na DNV ibisabwa mu mazi

IBIBAZO bibazwa

 

 

FAQ 1 - Ni ikihe kigeragezo co kwemera nshobora gusaba ku muyoboro wa API 5LD CRA upfutse canke ufise umurongo?

Nibura, API 5LD isabagusuzuma igerageza ry'amazi inyuma yo gupfuka/gupfuka no gusukura ubushuhe, kandi uburyo bwo gupima bukwiye kuba bufise .ikimenyamenya c'umukazo n'igihe co gufatarero uburebure bwose ntibushobora "guca" ataco bushitse ku bisabwa mu kigeragezo.

FAQ 2 - ni igiki gisobanura umuyoboro w'amazi mu RFQ y'umuyoboro wa aCRA?

Mu gutanga amasoko y’imiyoboro,umuyoboro wambayeni umuyoboro w'icuma ufisegusenyuka-ivyuma bishobora guhangana n'ivyuma (CRA)ifatanye n’imbere (clad), rero imbere itose ni CRA mu gihe umuyoboro utwara utanga inkomezi. API 5LD ipfuka CRA clad (n’umurongo) umurongo w’umurongo w’imiyoboro y’imiyoboro ya peteroli na gazi kavukire.

FAQ 3 - Nogereranya gute abahinguzi b'amatiyo y'impuzu canke abatanga amatiyo y'impuzu ntatakaje inzinguzingu za RFQ?

Saba ibintu bitatu imbere:(1)nimba ivyo bivugwa ariyambayecankeku murongokuri API 5LD,(2)muIbikoresho vy'imiyoboro(urugero rw’ishimikiro + urugero rwa CRA + urugero rw’uburemere bwa CRA), na(3)weld-iherezo ryiteguye (ingene CRA uruzitiro/iherezo ry'uruzitiro rufatwa ku bijanye n'ugufatanya-ins). Ivyo birinda umutego usanzwe w'"igiciro kimwe, inyubako itandukanye" iyo ugereranya abahinguzi b'imiyoboro y'impuzu.

FAQ 4 - Ni igiki nshobora gusobanura ku bijanye no gusudira amatiyo y'impuzu ku bihimba vy'umurima?

Kuberagusudira amatiyo, urufunguruzo ni ugukomeza guhangana n’ugusenyuka kwa CRA mu gihe cose c’uruzitiro-mu: gusobanura ugutegura kw’iherezo ry’ugusudira, kugenzura ukugaragara kwa CRA ku nzira y’ugusudira, n’ugusuzuma kwibanda ku bihimba vy’umurima (ku buryo uguhingura ntiguhagarara ngo hasubirwemwo). Iyo RFQ ivuga ngogusudira imiyoboro, ubifate nk'intumbero imwe-ariko ugumize amajambo y'amasezerano kuumuyoboro wambaye.
