APl 5L Igitigiri B Umuyoboro udafise umurongo-Incamake y'ubuhinga

API 5L Grade B ni kimwe mu bikoreshwa cane mu vyuma vy’ivyuma vy’umuyagankuba ku mirongo y’imiyoboro idafise umurongo kandi ifise amabuye y’agaciro mu mirongo y’amavuta, gazi n’amazi.

N’inkomezi z’umwimbu zitoyi cane .245 MPa (35.500)n’inkomezi zisanzwe z’ugukomera zigera kuri 100.000.415 MPa (60.200), iki kigero gitanga uburinganire bukora bw'inkomezi, ubushobozi bwo gukomera n'ubushobozi bwo gusudira, bikaba bituma gishobora gukoreshwa mu bikorwa rusangi-vy'imiyoboro.

Nk’uko vyasobanuwe muAPI 5Lkandi bihuye n'ISO 3183 L245, Umuyoboro w’umurongo wa Grade B wagenewe gukora neza mu gihe hari umuvuduko n’ubushuhe buringaniye. Kubera ko ifise ubushobozi bwo gukora neza kandi ikaba ifise inyifato nziza yo gukora, iratorwa kenshi ku bijanye n’imiyoboro yo ku butaka no ku kiyaga.

Munsi y’API 5Libisobanuro, umuyoboro w'umurongo ukoreshwa mu rwego rubiri rw'ibisobanuro vy'igicuruzwa:PSL 1kandiPSL 2. Itandukaniro hagati yavyo si mu mibumbe y’imiti n’imiterere y’ubuhinga gusa, ariko kandi no mu rugero rwo gusuzuma, kugerageza no gukurikirana bisabwa n’ingingo ngenderwako.

• PSL 1ni urugero rw’uburemere bw’ishimikiro ku bikorwa rusangi vy’imiyoboro.
• PSL 2yongerako imipaka ikomeye cane ku bijanye n’ubuhinga bwa shimi, ubukomezi n’ubuhinga bwa NDT, kandi isaba inyandiko zitomoye cane.

Amatiyo y'umunyuzigenewe canecane .H2S-irimwo canke CO2-ibidukikije vy'ubutunzi, aho ivyuma bisanzwe vy’umuyagankuba bishobora gushikirwa n’ibibi:

• Gusaduka kwatewe n'iyidrojeni (HIC)
• Gusaduka kw'imibabaro y'ubumara bwa sulfide (SSC)
• Urushe n'ugusenyuka mu bihe vy'aside

PSL 1→ Igiciro-umuti mwiza ku bikorwa rusangi vy'imiyoboro.

PSL 2→ Ubutungane bw’ubuhinga n’ubushobozi bwo gukurikirana ku bikorwa bihambaye vy’amavuta na gazi.

Ibikorwa vy'umunyu→ Ihinduka ridasanzwe riri munsi ya PSL 2 rihuye n’ibisabwa vya NACE ku bidukikije bifise aside.

Ivyo vyose hamwe, ivyo bipimo vy’ibisobanuro bituma abahinga bashobora guhitamwo umubumbe w’imiyoboro ubereye cane ku bijanye n’umuvuduko, ubushuhe n’imimerere y’ugusenyuka kw’umugambi wose-bituma habaho umutekano n’ukwizigirwa kw’igihe kirekire-.

Igizwe n'imiti (Urutonde rusanzwe)

Ivyuma bigenzurwa bituma umuntu ashobora gusudira neza kandi akagira ubushobozi bwo guhangana n’imibabaro y’ubuhinga n’ibidukikije.

Inkomezi z'Umwimbu (min):245 MPa (35.500)

Inkomezi z'ugukomera (min):415 MPa (60.200)

Ugukura:Irenga canke ingana na 20 % (bivanye n’uburebure bw’uruhome n’uburyo bwo gukora)

API 5L Ikigo ca Bimiyoboro ishobora gukorwa biciye mu nzira nyinshi zo gukora, bivanye n’ubunini n’inguvu z’uguhingura:

• Umuyoboro utagira umugozi (SMLS):Igizwe n’ugutera imbere bishushe canke gukuraho ibipande bikomeye, bikaba bitanga uburebure bumwe bw’uruhome be n’ubushobozi bwiza cane bw’ubuhinga.
• ERW (Igikoresho co guhangana n'umuyagankuba):Ikozwe mu bipimo vy'amazi bishushe-, vyiza ku mirongo y'amazi y'umuvuduko uri hagati n'ibikorwa vy'imibumbe.
• LSAW / SSAW (Igikoresho co mu mazi):Ikoreshwa ku migambi y’imiyoboro y’amazi y’uburebure bunini-, y’uburebure burebure-, cane cane mu gutwara amavuta na gazi.

Uburyo bwose bwo gukora bukurikira amategeko akomeyeIgenzura rya NDT, Igerageza ry'amazi, kandiigenzura ry'ingeronk’uko bitegekanijwe n’ingingo mfatirwako za API 5L.

API 5L Grade B ihuye cane n’ibi bikurikira mpuzamakungu n’ivya ASTM:

Naho ivyerekeye ubuhinga bisa, .API 5Ln’ibindi bisabwa ku bijanye n’ugukora neza kw’imiyoboro, ubukomezi, n’ubutungane bw’umurongo w’ugusudira kugira ngo amazi atwarwe ata nkomanzi.

API 5L Ikigero B umuyoboro udafise umugozini ikoreshwa cane muri:

• Amatiyo yo gutwara amavuta na gazi
• Uburyo bwo gutwara amazi n'ivu
• Amahinguriro y'amavuta n'amavuta ya peteroli
• Ibikorwa remezo vy'imiyoboro yo mu mazi no ku butaka
• Ibikorwa vy'imibumbe aho inkomezi ziringaniye n'ukwizigirwa gukomeye bisabwa

Ubushobozi bwayo bwo gukora vyinshi n'igiciro-bituma iba igikoresho gikundwa ku mirongo y'amazi y'ibikorwa vy'ubuhinga kw'isi yose.

Igihe uhisemwoAPI 5L Ikigo ca B, abahinga bakunda gusuzuma:

• Ivyangombwa vyo gukoresha:umuvuduko, ubushuhe, n'ibintu biringaniye
• Urugero rw'ibisobanuro:PSL 1 ku bikorwa bisanzwe, PSL 2 ku bikorwa bihambaye
• Urupapuro rw'imiyoboro:nta murongo canke bishizweko amabuye, bivanye n’ubunini n’ivyo bikenewe
• Gupfuka no kurinda:FBE, 3LPE, canke ivyuma bipfutse kugira ngo ntibisenyuke

API 5L Ikigo ca Bigereranya urugero rw’imiyoboro y’umurongo w’ivyuma vy’umuyagankuba ikoreshwa mu bikorwa remezo vy’inguvu kw’isi yose.

Kubera ko ifise inkomezi zishobora kwizigirwa, ikaba igaragara ko ishobora gusudirwa, be n’uko ishobora kuboneka ahantu henshi, irabandanya kuba umushinge w’imigambi yo gutwara amavuta, gazi n’amazi kw’isi yose.

KuriUmuyoboro w'umunani, turahingura kandi tugatangaAPI 5L Ikigero B imiyoboro y'umurongo idafise umugozi kandi ikozwemu kwubahiriza bimwe bishitseAPI, ISO, na DNVingingo mfatirwako-zituma habaho ibikorwa vy'ukwizigirwa ku bikorwa vyo ku butaka no ku nkengera y'ikiyaga.

IBIBAZO bibazwa

 

 

IKIBAZO CA 1: Ni igiki API 5L Grade B umuyoboro utagira umurongo ukoreshwa?

A1: Amavuta, gazi, n’amazi y’imiyoboro bisaba ko imiyoboro y’umurongo ikora neza.

IKIBAZO CA 3: Ni itandukaniro irihe riri hagati ya PSL1 na PSL2 ku bijanye n’imiyoboro y’umurongo wa Grade B?

A3: PSL2 isaba imipaka ikomeye cane y’ubuhinga bwa shimi, igerageza ry’ubukomezi bw’ingaruka, n’ubuhinga bukomeye cane bwo gukurikirana NDT/traceability.

IKIBAZO CA 4: Ni ryari nkeneye igikorwa ca API 5L co mu rwego rwa B (BNS/BQS/BMS)?

A4: Iyo iyo serivisi irimwo H2S/CO2 kandi isaba ko HIC/SSC ishobora guhangana n’ikigeragezo ca NACE.
