I-CRA Clad Pipe

Ipayipi eligqoke incazelo:ikhabhoni-ipayipi lensimbi elinokugqwala elincanyana-i-alloy resistant (CRA) ungqimba oluhlanganiswe ngensimbi endaweni engaphakathi (egqoke), noma ishubhu le-CRA elihlukile elifakwe ngaphakathi kwepayipi-lensimbi yensimbi (elayishiwe). Injongo iwukugcina ukumelana nokugqwala kwe-CRA lapho uketshezi luthinta khona, kuyilapho kugcinwa amandla nesakhiwo sezindleko sesithwali sensimbi{4}}se-carbon.

Ezokuthutha zikawoyela, igesi, namakhemikhali, ukugqwala akuyona nje inkinga yokunakekela{0}}kuchaza ubude bempilo balo lonke uhlelo. Amapayipi ensimbi yensimbi yendabuko, nakuba eqinile, ehla ngokushesha ngaphansi kokuchayeka{2}}kagesi omuncu noma emanzini olwandle. Ngakolunye uhlangothi, ukusebenzisa amapayipi aqinile e-corrosion{4}}resistant alloy (CRA) kuhle ngokobuchwepheshe kodwa akusimami ngokomnotho.

Ukuvala leli gebe, onjiniyela bakha i-I-CRA Clad kanye Nepayipi Elilayishiwe, isixazululo esithuthukisiwe se-metallurgical esihlanganayoamandla, ukumelana nokugqwala, kanye{0}}nokusebenza kahle kwezindlekoemkhiqizweni owodwa onobunjiniyela.

Izinketho Zezinto Zepayipi Elihlanganisiwe (Isisekelo + Isendlalelo se-CRA)

Emgogodleni wayo, i-CRA Claded Pipe iyi-ipayipi le-bimetallic, ukuhlanganisa izinsimbi ezimbili ezisebenza izindima ezihlukile kodwa ezihambisanayo:

Isendlalelo Sesakhiwo (Igobolondo Langaphandle):Insimbi-ephezulu yezinga eliphezulu noma{1}}insimbi ye-alloy (isb, i-API 5L X60/X65, ASTM A106, A333) ihlinzeka ngomthamo wokuthwala{9}}womshini.

Isithiyo Sokugqwala (Isendlalelo Sangaphakathi):Ama-alloys asekelwe ku-nickel{{0}noma angenasici afana ne-316L, i-Inconel 625, i-Alloy 825, noma i-Duplex 2205 idala ulwelwesi oluzinzile lokuvikela ngokumelene ne-CO₂, H₂S, -noketshezi olucebile lwe-chloride.

Lokhu kubhanqa kwensimbi kufeza lokho nensimbi engakwazi ukuyenza iyodwa: ipayipi elikwazi ukumelana nokucindezela okukhulu, izinga lokushisa, nokuhlasela okulimazayo amashumi eminyaka, ngisho nasezindaweni ezingaphansi kolwandle noma{0}}ezinosawoti omningi.

Ngokungafani nensimbi yensimbi evamile, amapayipi e-CRA abandayo adinga ukuhlangana okunembile phakathi kongqimba lwengxubevange nengxenye yensimbi. Izindlela ezisetshenzisiwe zincike ezidingweni zokusebenza kanye nokuqina kwesevisi:

Inqubo ngayinye ilandelwaukwelashwa kokushisa, ukuhlolwa kwe-ultrasonic, nokuhlolwa kwesixhumi esibonakalayoukuqinisekisa ukuzinza kwe-metallurgical kanye nokufakwa kwe-CRA okungaguquki.

Amanothi Enkundla Namanothi Okwenza

Ukushisela amapayipi agqokeikakhulukazi imayelana nokuvikela isendlalelo se-CRA endaweni yokushisela-ngoba ukuhlanjululwa, okokufaka ukushisa, kanye nokulungiswa kokugcina kwe-weld{1}}kunquma ukuthi ingabe ukumelana nokugqwala kugcinwa ngemva kokubophana{2}}. Abathengi ngokuvamile basho uhlobo oluhlanganyelwe (i-girth weld / tie-in spool), izimfuneko zokulungisa i-weld-ekupheleni, kanye nobubanzi bokuhlola ukuze ukwakhiwa kwe-offshore kungami ukuze kusetshenzwe kabusha.

Amanye ama-RFQ abhala lokhu njengeukushisela ipayipi elihlanganisiwe; izilawuli ezisebenzayo ziyafana: phatha ukuchayeka kwe-CRA endaweni yokushisela, sebenzisa izinto ezisebenzisekayo ezihambisanayo, futhi uqinisekise isimo sokugcina se-CRA endaweni yokushisela.

• Ukulungiswa kokuphela-kwe-Weld:Chaza i-bevel + CRA edge treatment ukuze i-tie-in inganqamuli i-CRA ngokungalindelekile.
• Ukulawula okokufaka ukushisa nokunciphisa amanzi:Gcina ikhemistri ye-CRA kubuso be-weld izinzile ukuze ugweme ukushisela "okubukeka kukuhle, kugqwale kamuva".
• Ukugxila kokuhlola:Idinga ububanzi be-NDT/PMI ezindaweni zokushisela uma uhlelo lokwamukela iphrojekthi lufuna lokho.

Epayipini le-CRA, "ukugqokisa" nokuthi "umugqa" akuwona imigomo yokuthenga eshintshashintshayo. Ukukhetha okulungile kuncike ekutheni yini engase ingahambi kahle ekukhiqizeni nasekuhlanganisweni-ku-CRA (i-CRA exposure at weld ends, liner movement, bond integrity), kanye nalokho iphrojekthi edinga ukukufakazela ekutholeni. I-Octal Pipe ngokuvamile isebenzisa uhlu lokuhlola olungezansi ukuze igcine ama-RFQ eqhathaniseka futhi nokugwema ukubanjwa kwesiteji-sekwephuzile ku-spoolbase.

Ama-alloys e-CRA akhethwa ngokuya ngendlela yokugqwala kanye nenqubo yamakhemikhali. Ukucushwa okujwayelekile kufaka:

Lezi zinhlanganisela ziqinisekisa lokhoubuqotho bemishini nokuvikela ukugqwalazifinyelelwa kanyekanye-ngaphandle komthwalo wezindleko wokwakha okuphelele kwe-CRA.

A Ipayipi le-CRAIsixazululo sivame ukucaciswa lapho i-carbon steel iyodwa ingakwazi ukubekezelela uketshezi olukhiqizwayo ngesikhathi sokuklama, kodwa ipayipi eliqinile le-CRA alikona ukonga. Izimbangela ezivamile zihlanganisa ingozi yokugqwala ye-CO₂, ukukhathazeka ngesevisi emuncu, ukuphatha{1}i-chloride ephezulu, kanye nemigqa egelezayo yasogwini lapho ukufinyelela kokulungisa kunqunyelwe khona. Kulezi zimo, umgomo osebenzayo wokuthenga akuyona "i-CRA yonke indawo," kodwa indawo emanzi ye-CRA elawulwayo enokushisela okubikezelwayo kanye nobufakazi bokuhlola.

I-CRA Clad Pipes ifakwe emhlabeni wonke ezindaweni zonke lapho ubungozi bokugqwala kanye nesidingo sesakhiwo hlangana khona:

• Imigqa yokugeleza kwamanzi ajulile kanye nama-subsea manifoldsephethe uketshezi lwe-multiphase
• Umjovo we-CO₂ kanye nezinhlelo zokutakula ezithuthukisiwe
• Izitshalo zokukhipha usawoti emanzini asogwini nolwandle
• Izikhungo zokucwenga kanye ne-petrochemicalukucubungula i-acidic noma i-chloride media
• Izimboni zamandla namakhemikhalingaphansi kwezinga lokushisa eliphezulu kanye nemijikelezo yokucindezela

Ngobuqotho be-CRA buqinisekiswe ngaphansiI-NACE MR0175 / ISO 15156futhiI-API 5LD, la mapayipi angasebenza iminyaka engu-20-30 ngokulungiswa okuncane.

Ukuze abathengi ukuqhathanisaabakhiqizi bamapayipi abagqokekanye nomuntu ofanelekayoumphakeli wamapayipi agqoke, inzuzo ye-Octal Pipe ibonakala emininingwaneni yokunikezelwa evamise ukubangela ukubanjwa kwephrojekthi: sikhiya umzila wokwakha we-clad/liner ku-RFQ, silawula ukulungela kokushisela-ukuze amalunga enkundla angavezi noma alimaze isendlalelo se-CRA, futhi sigcine ukulandeleka kuqinile ukuze okokusebenza kwe-CRA kanye{1}}nenkampani yensimbi{1}}ephethwe yinsimbi kuhlanganiswe. Empeleni, lokho kusho ukuthunyelwa okulethwa ngama-ID wamapayipi afanayo, sula inqwaba{3}}yokumaka ileveli yenqwaba, kanye nesethi yedokhumenti exhumanisa ipayipi eliyisisekelo nesendlalelo se-CRA ohlwini olufanayo lokulethwa{4}}ukuze amaqembu akhiqizayo angaphoqwa-emsebenzini wokuhlonza kabusha ngaphambi kokushiselwa.

• Ukuvikelwa-kwezendlalelo ezikabili ngokumelene ne-CO₂, H₂S, nama-chlorides
• Amandla-esikhathi eside esakhiwo anezindleko ezincishisiwe ze-CRA
• Ihambisana ne-standard pipeline welding kanye nokufakwa
• Ilungele i-deepwater, i-HPHT, namapayipi-esevisi amuncu
• Igunyazwe ku-API, ASTM, kanye nezidingo zasolwandle ze-DNV

FAQ

 

 

I-FAQ 1 - Yikuphi ukuhlolwa kokwamukelwa okufanele ngikucele ku-API 5LD CRA egqokiwe noma ipayipi elilayishiwe?

Okungenani, i-API 5LD idinga iukuhlola ukuhlolwa kwe-hydrostatic ngemva kokuvala/ulwelwesi nokwelashwa kokushisa, futhi uhlelo lokuhlola kufanele lube naloubufakazi obuqoshiwe bokucindezela nokubamba isikhathingakho ubude ngabunye abukwazi "ukudlula" ngaphandle kokuhlangabezana nemfuneko yokuhlolwa.

I-FAQ 2 - lisho ukuthini ipayipi eligqoke ipayipi le-aCRA RFQ?

Ekuthengeni okuhamba phambili,ipayipi eligqokileiyipayipi-yensimbi yensimbi ene-ungqimba lwe-corrosion{0}}resistant alloy (CRA).iboshelwe endaweni yangaphakathi (egqokile), ngakho indawo emanzi i-CRA kuyilapho ipayipi elithwalayo linikeza amandla. I-API 5LD imboza ipayipi lensimbi le-CRA eligqokile (kanye nelayini) lamapayipi e-petroleum negesi yemvelo.

I-FAQ 3 - Ngibaqhathanisa kanjani abakhiqizi bamapayipi agqokile noma abahlinzeki bepayipi abagqoke izingubo ngaphandle kokumosha imijikelezo ye-RFQ?

Buza izinto ezintathu ngaphambili:(1)noma ngabe isishogqokilenomakulayiniku-API 5LD,(2)iimpahla yamapayipi agqoke(ibanga eliyisisekelo + ibanga le-CRA + isisekelo sokujiya se-CRA), kanye(3)weld-ukuphela ukulungela (indlela ungqimba/umugqa womugqa we-CRA uphathwa ngayo ukuze uthayiwe-). Lokhu kugwema isicupho esivamile "sentengo efanayo, ukwakhiwa okuhlukile" lapho kuqhathaniswa abakhiqizi bamapayipi agqoke.

I-FAQ 4 - Yini okufanele ngiyicacise ngokushisela amapayipi anezindwangu emajoyintini enkundla?

Ngobaukushisela amapayipi agqoke, ukhiye ukugcina ukumelana nokugqwala kwe-CRA kuqhubekayo kulo lonke uthayi-ku-: chaza ukulungiswa kokuphela kwe-weld-, ukulawula ukuchayeka kwe-CRA endaweni yokushisela, kanye nokugxila kokuhlolwa emajoyini enkundla (ukuze ukwakhiwa kungami ukuze kusetshenzwe kabusha). Uma i-RFQ ithiukushisela ipayipi elihlanganisiwe, kuphathe njengenhloso efanayo-kodwa gcina amagama enkontileka evuliweipayipi eligqokile.
