Ubwoko bwamavuta yo guhuza imiyoboro

Guhuza imiyoboro ya peteroli ni igice cyingenzi cyumuyoboro wimyitozo, igizwe na pin hamwe nagasanduku gahuza kumpera yumubiri wimyitozo. Kugirango uzamure imbaraga zo guhuza, uburebure bwurukuta rwumuyoboro busanzwe bwiyongera kumwanya uhuza. Ukurikije uburyo uburebure bwurukuta bwiyongereye, amasano arashobora gushyirwa mubwoko butatu: guhungabana imbere (IU), guhungabana hanze (EU), no guhagarika umutima imbere (IEU).

Ukurikije ubwoko bwurudodo, imiyoboro ya drine ihuza igabanijwe mubwoko bune bukurikira: Flush Imbere (IF), Umuyoboro wuzuye (FH), Ibisanzwe (REG), na Numero Ihuza (NC).

1. Guhuza Imbere (NIBA) Kwihuza

NIBA amahuza akoreshwa cyane cyane mumyitozo ya EU na IEU. Muri ubu bwoko, diametre yimbere yikigero kinini cyumuyoboro uhwanye na diametre yimbere yo guhuza, nayo ihwanye na diametre yimbere yumubiri. Bitewe nimbaraga nke ugereranije, NIBA ihuza rifite imipaka isanzwe ikoreshwa. Ibipimo bisanzwe birimo agasanduku k'urudodo rw'imbere rwa diametero ya 211 (NC26 2 3/8 ″), hamwe n'udodo twa pin tera kuva kumutwe muto kugeza kumpera nini. Ibyiza bya NIBA ihuza ni ukurwanya kwayo kwinshi kumazi yo gucukura, ariko kubera diameter nini nini yo hanze, ikunda gushira byoroshye muburyo bukoreshwa.

2. Umuyoboro wuzuye (FH)

Ihuza rya FH rikoreshwa cyane cyane kumiyoboro ya IU na IEU. Muri ubu bwoko, umurambararo w'imbere w'igice cyijimye kingana na diametre y'imbere ihuza ariko ni ntoya kuruta diameter y'imbere y'umubiri. Nka NIBA ihuza, pin ya pine ya FH ihuza imashini kuva ntoya kugeza kumpera nini. Agasanduku k'agasanduku gafite diameter y'imbere ya 221 (2 7/8 ″). Ikintu nyamukuru kiranga FH ihuza ni itandukaniro ryimiterere yimbere, ibyo bigatuma habaho umuvuduko mwinshi wo gutobora amazi. Nyamara, diameter ntoya yo hanze ituma idakunda kwambara ugereranije na REG ihuza.

3. Guhuza bisanzwe (REG)

Ihuza rya REG rikoreshwa cyane cyane kumiyoboro ya IU. Muri ubu bwoko, diameter y'imbere y'igice cyabyimbye ni ntoya kuruta diameter y'imbere yo guhuza, nayo ubwayo ikaba ntoya kuruta diameter y'imbere y'umubiri. Agasanduku k'insanduku y'imbere ni 231 (2 3/8 ″). Muburyo bwa gakondo bwo guhuza, REG ihuza ifite imbaraga nyinshi zo guhangana nogutwara amazi ariko diameter ntoya yo hanze. Ibi bitanga imbaraga nyinshi, bigatuma bikwiranye neza nu miyoboro ya dring, bits, hamwe nibikoresho byo kuroba.

4. Guhuza inomero (NC)

NC ihuza ni urukurikirane rushya rusimbuza buhoro buhoro NIBA hamwe na FH ihuza bimwe na bimwe bya API. Ihuriro rya NC ryitwa kandi National Standard coarse-thread series muri Reta zunzubumwe zamerika, hagaragaramo insanganyamatsiko ya V. Ihuza rya NC rishobora guhinduka hamwe na kera ya API ihuza, harimo NC50-2 3/8 ″ NIBA, NC38-3 1/2 ″ NIBA, NC40-4 ″ FH, NC46-4 ″ NIBA, na NC50-4 1/2 ″ NIBA. Ikintu cyingenzi kiranga NC ihuza nuko bagumana umurambararo wa diametre, taper, ikibanza cyurudodo, nuburebure bwurudodo rwakera rwa API ihuza, bigatuma bihuza cyane.

Nkigice cyingenzi cyimiyoboro ya drillage, imiyoboro ya drine ihuza iratandukanye cyane mubijyanye nimbaraga, kwambara, hamwe no kurwanya amazi, bitewe nubwoko bwurudodo nuburyo bwo gushimangira urukuta. NIBA, FH, REG, na NC ihuza buriwese afite ibiranga byihariye kandi bikwiranye nibikorwa bitandukanye. Hamwe niterambere mu ikoranabuhanga, ihuriro rya NC rigenda risimbuza buhoro buhoro ibipimo bishaje kubera imikorere yazo nziza, bihinduka inzira nyamukuru mubikorwa byo gucukura peteroli bigezweho.
