Igipfukisho c'umuyoboro

Umuyoboro w'icumani umugozi w’imibumbe ufata iriba ryuguruye kandi utanga inzitizi yo gutera simenti no kwitandukanya n’ibice-amahitamwo yawe y’ivyuma agira ingaruka zitaziguye ku nzira z’ugusenyuka/uguturika n’ubutungane bw’iriba bw’igihe kirekire. gupfuka urutonde rwose rw’ivyuma n’ubwoko bw'ihurirokugira ngo bashobore gushitsa ibisabwa mu mugambi wo kw’isi yose.

Igihe uhitamwo igipfukisho c’iriba rishasha, ibibazo vya mbere umuhinga mu vy’ugucukura canke w’ugutanga amasoko wese akeneye kwishurwa ni vyoroshe ariko birahambaye cane:

• Mbega iki gipfukisho coshobora guhangana n’uburebure bw’iriba ryanje, umuvuduko w’amazi, n’umuzigo wo gusenyuka?
• Mbega uwugurisha atanga amanota ahamye (atari ibikoresho vy'umubabaro mwinshi)?
• Mbega indodo ni izo kwizigirwa bihagije ku bijanye n’uburemere bwanje bw’ivu n’umuvuduko wanje?
• Boba bashobora gutanga ubunini n’uburebure nyavyo bikenewe ku mugambi wanje wo kwiruka?
• Mbega hariho ugukurikirana n’ukugenzura uburyo bushitse inyuma y’urugingo rwose?

Octal Pipe itanga API 5CT casing yubatswe hirya no hino y'ivyo bikenewe vy'umugambi-atari gusa API ntoya.
Igihuza cose dutanga gifise ubuhinga bugenzurwa, imiterere y’ubuhinga igenzurwa, igenzura ry’urugero rwa PSL2-, n’ugushikama kw’ubushuhe kugira ngo bimenyekane ko bishobora gusenyuka, guturika, no gukora neza mu mfuruka y’iriba.

• P110 / Q125– inkomezi zisumba izindi zose z'imigero y'ugusenyuka y'imbere canke y'imbere -

Igitigiri cose gishobora gutangwa mu 2019.PSL-1, PSL-2 canke PSL-3., n'amaraporo yuzuye y'igerageza ry'ibikoresho (EN 10204) n'igenzura ry'uwundi muntu kugira ngo bihure n'imimerere nyayo y'iriba ryawe.

Igiciro c'Imiyoboro y'Igipfukisho: Ico Akenshi Kijana Umubare

• Ihitamwo ry’uguhuza ni ryo ry’agaciro kanini: BTC vs premium si ikintu gito co kwongerako-kuri-gukora-up n’ingene ingamba zo gukingira nivyo uriko uriha.
• Ibisabwa vyo gukoresha Sour-bihindura inzira yose: Ibisabwa bijanye na SSC/NACE- (igihe bishoboka) biragira ico bikoze ku guhitamwo ivyuma no ku rugero rwa QA.
• Igitigiri c'igenzura kigomba kugereranywa: iyo igiciro kimwe kirimwo thread gauging / NDT / 3.2 ikindi kitarimwo, "igiciro" ntikigereranywa.

• Inyuma y'umurongo (OD): 4-1/2′′ – 20′′ (114.3 mm – 508 mm), ipfutse hafi ubunini bwose bw’igipfukisho gikoreshwa kw’isi yose.
• Uburemere bw'uruhome n'uburemere: Urutonde rwuzuye ku meza ya API 5CT – kuva ku buremere buke 9.50 lb/ft gushika ku buremere -uruhome 169.00 lb/ft, gutuma habaho ukuboneka kw’imirongo y’ubutaka butari kure cane biciye ku gipfukisho c’ibikorwa vy’uburebure burengeye, burengeye -gusenyuka.
• Uburebure bwa API busanzwe: – Urutonde rwa 1 (R1): 16 – 25 ft (4.88 – 7.62 m) – ikoreshwa cane cane ku butaka iyo uburebure bw’ugutwara bugabanywa –Urutonde rwa 2 (R2): 25 – 34 ft (7.62 – 10.36 m) – izwi cane kubera ibikoresho vyo ku butaka n’ibikoresho bigufi vyo guterura ku nkengera y’ikiyaga –Urutonde rwa 3 (R3): 34 – 48 amafuti (10,36 – 14,63 m) –uburebure bwacu bufise ibikoresho vyinshi cane– bikundwa n’abakoresha bakuru ku migambi yo mu mazi, mu mazi maremare no mu vyo gushora ibintu hanze (bigabanya amahuzu na ≈30 % vs R2)
• Uburebure busanzwe & budasanzwe: Uburebure nyabwo bwo guca -ku -bushika kuri metero 15 (49.2 ft), amaguru y’imbwa, n’uburebure bw’ugucapura bwakozwe ku buryo butegekanijwe n’nta n'ibindi bihembo vyo gukata canke gusesaku ngano nyinshi zisanzwe (4-1/2′′ gushika kuri 13-3/8′′).

OCTG igipfukisho c'ibikoresho vyo kwimba ubutaka

Ku mariba asanzwe y’amavuta na gazi yo ku butaka, igipfukisho cacu ca OCTG c’ibikoresho vyo gucukura ku butaka gitangwa ahanini muri J55, K55, N80 na P110 gifise indodo za BTC/STC/LTC. Ivyuma vyinshi mu burebure bwa R2/R3 kandi biteguye-ku-gukoresha indodo bisigura ko ushobora kwubaka imirongo yuzuye yo hejuru, hagati n'iyo gukora n'uguhindura insyo nke n'igihe gito co kurindira.casing pipe oil and gaz:

Ivyuma vyo ku ruhande: vyibanda ku gufasha mu guhingura ibintu bitari kure cane no ku gushikama kw’akazi ka sima; umuguzi afunga OD/grade/uguhuza hirya no hino y’ugufata rig n’umugambi wo gutera simenti.

Igipfukisho co hagati: gitoranywa kugira ngo gitandukanye uturere dutera ingorane; umuguzi yibanda ku gusenyuka/guturika kw’ibahasha no gushinga amazi mu kwizigirwa.

Igipfukisho c'umwimbu: gica kiba intambamyi y'igihe kirekire-; umuguzi yibanda ku nzira yo gukingira ihuriro n'ibisabwa vy'umunyu-service/SSC (igihe bishoboka).

Ivyuma vy'imiyoboro y'ibibanza vyo ku nkengera y'ikiyaga n'ibikoresho vyo guterura

Ivyuma vyo ku nkengera y’ikiyaga n’ibikoresho vyo gutera imbere bisaba umutekano mwinshi. Turatanga ibipimo vy’ibikorwa bikomeye-uruhome P110/C110 n’ibisharira-ibipimo vy’ibikorwa nka L80-13Cr na T95 n’igerageza ryuzuye rya NACE MR0175 n’ugushingira intahe kw’uwundi muntu.

API 5CT igipfukisho co gucukura mu buryo bujanye n'uburinganire

Mu mariba y’inzira n’ay’uburinganire, igipfukisho gitegerezwa kurokoka amaguru menshi y’imbwa, umuvuduko n’uguca ibice kw’inzira nyinshi-. Igikoresho cacu ca API 5CT co gucukura mu buryo bubereye no mu buryo buringaniye gikoresha inkomezi zikomeye cane zifise uburebure bukomeye n’ubugenzuzi bw’uguhuza, hamwe n’indodo zidasanzwe zifise uruhusha aho bikenewe. Ivyo bigabanya ingorane zo gukora-up, ingorane zo gusohoka n’ibiciro vyo gukora mu mariba y’amabuye y’agaciro n’amariba yagutse.

Itiyo y'amazi y'amariba n'amariba y'ubushuhe bwo hasi

Ku mariba y’amazi n’imigambi y’ubushuhe bwo hasi, umuyoboro wacu wo gupfuka amariba y’amazi n’amariba y’ubushuhe bwo hasi ufatanya ivyicaro vyiza vy’umuyagankuba canke vy’ivyuma bifise ubugororotsi bugenzurwa be n’ibintu bishobora gupfukwa imbere. Ivyo bifasha kuguma bishikamye mu mva, bikarinda gusenyuka no gusenyuka, kandi bikaha amapompo yawe n’ibikoresho vyawe vyo kurangiza umugozi w’ivyuma usukuye kandi uramba-umara igihe kirekire.

Ibisabwa mu gihe co gucukura (CWD)

• Impinduka z'imbere y'ihuriro: CWD ifata igipfukisho nk'urudodo ruzunguruka, rero ufunga ubwoko bw'ihuriro/gukora-up imyimenyerezo maze ukanka ibigenderwako bikomeye kuruta uko bisanzwe.
• Ukwambara n’ugufata ukuri: vuga ibidukikije vyitezwe kwambara n’uburyo bwo gufata kugira ngo uwugurisha ashobore guhuza uburinzi bw’iherezo, uburinzi bw’indodo, n’indero yo gupakira.
• Kwemera kwibanda: bisaba urugero rw'ugukurikirana n'urudodo rwo kugenzura ibimenyamenyaiyo bigaragajwe, kuko ukunanirwa kwa CWD kwerekana nk'ingorane n'igihe co guhagarara, atari nk'"ibibazo vy'imiyoboro."
