Ishadi Losayizi We-API Tubing kanye Ne-Casing: Inkomba Ephelele Yezincazelo ze-OCTG

Ukwakhiwa komthombo kawoyela negesi kuncike emikhiqizweni yeshubhu eyakhiwe ngokwezindinganiso eziqondile zobukhulu kanye nezemishini. Phakathi kwezincazelo ezibhekiselwa kakhulu emhlabeni wonke yi-API SPEC 5CT, enyatheliswa yi-American Petroleum Institute, elawula ubukhulu, amazinga ezinto zokwakha, kanye nezidingo zokuhlola zekheshi kanye namashubhu asetshenziswa emisebenzini ephezulu.

KwaRoyal Steel Group, sihlinzeka ngephothifoliyo ephelele ye-casing kanye ne-tube ehambisana ne-API 5CT kuzo zonke izinhlobo zobukhulu, ubukhulu bodonga, kanye namabanga ensimbi. Ngezansi kunesithenjwa esisebenzayo esihlanganisa ubukhulu obujwayelekile, ububanzi besisindo, ukukhethwa kwamabanga, kanye nezicelo ezijwayelekile zasensimini - okuhloswe ukusiza amaqembu okuthenga, onjiniyela bokubhoboza, kanye nabaphathi bephrojekthi ukuthi bacacise umkhiqizo ofanele we-OCTG wohlelo lwabo lomthombo.

Kuyini i-API Casing kanye ne-Tubing?

Ibhokisiyipayipi lesakhiwo elihlanganiswe ngokhonkolo emgodini womthombo ngemva kokubhoboza. Imisebenzi yalo eyinhloko ukuvimbela ukubhidlika kwemigodi, ukuhlukanisa ukwakheka okukhiqizwayo nokungakhiqizi, kanye nokuhlinzeka ngesithiyo esiqukethe ingcindezi empilweni yomthombo.

Ukufaka amapayipiyipayipi elincane elihamba ngaphakathi kwebhokisi lapho kugeleza khona ama-hydrocarbon akhiqizwayo (noma uketshezi olufakwe ngaphakathi) liye phezulu. Ngokungafani nebhokisi, amapayipi ngokuvamile awafakwanga usimende futhi angadonswa futhi ashintshwe ngesikhathi sokusebenza.

Yomibili imikhiqizo iwela ngaphansi kwesigaba esibanzi se-OCTG (Oil Country Tubular Goods), esihlanganisa nepayipi lokubhoboza, amajoyinti ezinjana, ama-coupling, kanye nokuxhumeka kwe-premium.

Ikesi Elingaphezulu 13⅜" – 20"+ Izikhawu ezingajulile; ivikela izindawo zamanzi ahlanzekile futhi isekela inhloko yomthombo
Ikesi Eliphakathi 9⅝" – 13⅜" Ivala izindawo eziyinkinga (i-shale, usawoti, ukulahleka kokujikeleza kwegazi) engxenyeni ephakathi nendawo yomthombo
Ibhokisi Lokukhiqiza 4½" – 7" Ihlukanisa ichibi futhi inikeze umsele wokukhiqiza impilo yonke yomthombo

Ingxenye Yomthombo Ububanzi Obujwayelekile be-OD Inhloso

Ikhesi Lomphezulu 13⅜" – 20"+ Izikhawu ezingajulile; ivikela izindawo zamanzi ahlanzekile futhi isekela ikhanda lomthombo
Ibhokisi Eliphakathi 9⅝” – 13⅜” Livala izindawo ezinenkinga (i-shale, usawoti, ukulahleka kokujikeleza kwegazi) engxenyeni ephakathi nendawo
Ikhesi Lokukhiqiza elingu-4½" – 7" Lihlukanisa ichibi futhi linikeze umsele wokukhiqiza impilo yonke yomthombo

Izinhlobo Zentambo Nokuxhumeka

I-STC (Intambo Emfushane Ehlanganisiwe): Izinga elijwayelekile lezintambo zekhava ezinomfutho ophansi, ezingajulile.
I-LTC (I-Long Thread Coupled): Ukuqina kwamalunga okuthuthukisiwe ukuze kube nensizakalo ejulile noma ephezulu.
I-BTC (Intambo Ehlanganisiwe Ye-Buttress): Umthamo ophezulu wokuthamba kanye nokusebenza kokuvala igesi; isetshenziswa kabanzi ekukhiqizeni kanye nasezintanjeni eziphakathi nendawo.

Ukuxhumeka kwe-premium (isb., i-VAM, i-TMK, isitayela se-Hydril) kuyatholakala ngensizakalo yokucindezela okuphezulu/yokushisa okuphezulu (i-HPHT) kanye neyokugqwala lapho ukuxhumeka kwe-API kunganele.

Ubukhulu be-OCTG Tubing kanye neShadi Lesisindo

Usayizi Ovamile Wepayipi

Usayizi Ojwayelekile (amasentimitha) I-OD (mm)
1.050" 26.67

Ubukhulu Bodonga

Ubukhulu bodonga lwepayipi le-API elijwayelekile busukela ku-0.083" (2.11 mm) kuya ku-0.400" (10.16 mm). Isibonelo, intambo yepayipi engu-2⅞" ivame ukunikezwa ku:
0.217" (5.51 mm) — NUE, ingcindezi ephansi
0.276" (7.01 mm) — isevisi ejwayelekile
0.308" (7.82 mm) — ingcindezi enzima, ephezulu
Amapayipi odonga olujiyile adlula u-16 mm angenziwa ngokwezidingo zakho zemithombo ejulile, enomfutho ophezulu, noma egqwalisayo.

Ububanzi Bobude (i-API 5CT)

Ibanga Izinyawo Amamitha
R1 18 – 22 ft 5.49 – 6.71 m
R2 27 – 30 amamitha 8.23 – 9.14 m
R3 38 – 42 ft 11.58 – 12.80 m

 

I-R2 ivame kakhulu emisebenzini yasemanzini; i-R3 inciphisa inani lokuxhumeka futhi iyathandwa lapho isikhathi semishini kanye nobuqotho bokuxhumeka kuyizinto eziza kuqala.

Izinhlobo Zemicu

I-NU (Okungacasuli): Ukuphazamiseka kwangaphandle okuvamile akusebenzi; kusetshenziswa ekuhlinzekeni ngengcindezi ephansi.
I-EU (Ukuphazamiseka Kwangaphandle): I-pin eqinisiwe ukuze kuthuthukiswe ukusebenza kokuthambekela kanye nokucindezela; uxhumano lwepayipi oluvame kakhulu.
Imicu Ephakeme (i-VAM, i-TMK, njll.): Ukuvala okungenagesi, okuvala insimbi ibe yinsimbi ukuze kuvinjwe i-HPHT, indawo yokugcina igesi, kanye nezindawo ezigqwalisayo.

Ukufaka amapayipi ngesicelo

Ububanzi Bosayizi Ukusetshenziswa Okuvamile
1.050" – 2.375" Imithombo enengcindezi ephansi noma ephansi; ukuqedwa kwemigodi emincane
2.875" – 3.500" Imithombo yokukhiqiza evamile — uhla olusetshenziswa kakhulu
4.000" – 4.500" Imithombo yezinga eliphezulu, ukukhushulwa kwegesi, kanye nokufakwa kwamanzi/i-CO₂

Amabanga Ensimbi Nezakhiwo Zemishini

Ukuqokwa kwebanga ku-API 5CT kubonisa amandla amancane okukhiqiza ezinkulungwaneni ze-psi (isb., i-N80 = isivuno esincane se-psi esingu-80,000). Amabanga aphezulu anikeza ukumelana okukhulu kokucindezelwa nokuwa kodwa angase abe sengozini enkulu yokuqhekeka kokucindezeleka kwe-sulfide (SSC) kusevisi emuncu.

Isifinyezo Sempahla Yomshini

Izinto Ezibalulekile Okufanele Uzicabangele

Ukukhetha i-casing efanele kanye ne-tube akuyona nje indaba yokufanisa i-OD kanye nobukhulu bodonga. Umklamo ophelele we-tube kufanele uhlanganise lezi zinto ezilandelayo:

Ukujula Komthombo kanye Nephrofayili Yokucindezela— Inquma ukugoba okudingekayo, ukuqhuma, kanye nezilinganiso zokudonsa, okuqhuba ibanga kanye nokukhethwa kwesisindo.

Indawo Yokugqwala— I-CO₂, i-H₂S, i-chloride, kanye namazinga okushisa aphezulu kungadinga ama-alloy angu-13Cr, i-super 13Cr, noma ama-duplex esikhundleni sensimbi yekhabhoni.

Ukwakheka kanye ne-Geomechanics— Ukuvuvukala kwe-shale, ukukhukhuleka kukasawoti, kanye nokucindezela okungavamile kuthinta ukujula kokubeka i-casing kanye nobukhulu bodonga.

Uhlobo Lokuxhumeka— Izintambo ze-API eziyindilinga noma ze-buttress zanele imithombo eminingi; ukuxhumeka kwe-premium kuyadingeka ukuze kuvalwe ngokuqinile ngegesi noma ezimweni zomthwalo omkhulu.

Imininingwane Yokulawula kanye Nomqhubi— Abaqhubi abaningi babeka izidingo ezengeziwe ngale kwe-API 5CT, okuhlanganisa i-NDE eyengeziwe, ukuhlolwa kobulukhuni, kanye nobukhulu bokukhukhuleka.

Amandla e-OCTG e-Royal Steel Group

Iqembu Lensimbi Yasebukhosini ikhiqiza futhi ihlinzeka nge-API 5CT casing kanye ne-tube enalolu hlu olulandelayo:

Ububanzi bosayizi ogcwele:Isilinganiso esingu-1.050" kuya ku-20", esinobukhulu obukhulu kanye nosayizi abakhelwe ngokwezifiso abatholakalayo.

Amamaki aphelele:Ama-alloy amelana nokugqwala e-H40, J55, K55, N80, L80, C90, T95, P110, Q125, kanye ne-13Cr / super 13Cr.

Izinketho zokuxhuma:I-STC, i-LTC, i-BTC, i-NU, i-EU, kanye nokuxhumeka okunezintambo ze-premium uma kuceliwe.

Ukuqinisekisa ikhwalithi:Ukuhlolwa kwe-UT/MT okuphelele, ukuhlolwa kwe-hydrostatic, inhlolovo yokuqina, kanye nokuhlolwa komuntu wesithathu (BV, SGS, DNV) kuyatholakala.

Ukulethwa:Ubude obungahleliwe be-R1 / R2 / R3, kanye nokuhlanganiswa kanye nokunikezwa kwejoyinti lenjana njengephakheji ephelele.

Umkhiqizo wethu uqinisekiswe yi-API SPEC 5CT kanye ne-ISO 9001, kanye nemibiko yokuhlolwa kwemishini (ama-MTR) enikezwayo kuwo wonke amazinga okushisa kanye nenani.
