Qhov sib txawv ntawm Casing Couplings thiab Tubing Couplings

Casing muaj couplings, thiab tubing muaj couplings - lawv lub hom phiaj ntawm kev sib txuas tubing yog tib yam. Ntawm qhov tod tes, tseem muaj qee qhov sib txawv ntawm ob.

◆ Hom Dimensions thiab Hom

Tubing couplingsFeem ntau muaj qhov siab tshaj plaws sab nraud ntawm 4 1/2". Txij li cov tubing yog siv rau kev ua haujlwm drilling (cov laum / lub twj tso kua mis yog nyob rau hauv cov tubing), cov coupling hom muaj ntau yam sib txawv thiab nruj dua li cov casing. (EUE) couplings, tseem hu ua EU couplings, feem ntau siv thiab suav hais tias yog hom kev sib txuas zoo tshaj plaws rau tubing nrog EU kawg (EUE) txuas txuas kuj tseem hu ua UPTBG lossis Upset Tubing nrog Bottleneck Geometry.

◆ Qhov zoo ntawmEUE Couplings

Vim qhov chim siab (thickened) kawg ntawm cov tubing, EUE kev sib txuas muaj peev xwm ua kom muaj kev ntxhov siab zoo dua piv rau cov kab txuas txuas. Tubing xaus txuas mus rau lub coupling lub puab phab ntsa ntawm ib tug tapered xov. Lub coupling xaus txuas mus rau lub raj siv tib lub suab ntawm cov xov ncaj. Qhov kev sib txuas tsim no txo ​​qhov qaug zog tawg teeb meem los ntawm kev ntxhov siab pom hauv cov txuas uas twb muaj lawm. EUE couplings zoo tiv thaiv tubing txoj hlua tsis ua haujlwm hauv qhov dej.

◆ Lwm yamTubing CouplingHom

Buttress couplings, qhov twg lub coupling phab ntsa thickness phim lub cev tubing, yog lwm hom siv rau kev sib txuas tubing. Cov no yog hu ua NU kawg (NUE) tubing lossis TBG (Tubing nrog Grooved Geometry).

◆ Qhov ntev

Casing couplingsmuaj qhov ntev ntau dua 4 1/2 ntiv tes. Tsis zoo litubing couplings, uas feem ntau tsis tas yuav muaj kev ntxhov siab (thickening), yog li lawv tsis yog kev sib txuas. Muaj ob peb hom tseem ceeb:

BTC - Buttress Threaded Couplings

Cov no muaj tib lub phab ntsa thickness raws li lub cev casing.

LTC - Ntev ThreadedCasing Couplings

STC - Luv XovCasing Couplings

Qhov ntev thiab luv xa mus rau qhov sib txawv ntawm qhov sib txuas ntev, tab sis cov phab ntsa thickness sib phim lub casing.

Lawv yog ib qho tseem ceeb rau kev txuas ob ntu ntawm cov yeeb nkab casing. Txoj kev tsim khoom yog tib yam li rau cov yeeb nkab seamless - cov yeeb nkab kawg muaj cov xov sab hauv los txuas rau cov coupling threaded xaus saum toj thiab hauv qab. Txhawm rau kom muaj kev sib txuas nruj nruj, muaj cov kev cai nruj rau cov xov precision.

◆ Cov qib steel thiab kev kho cua sov

Rau ob leeg tubing thiabcasing couplings, qib steel thiab kev kho cua sov ntawm cov couplings yuav tsum sib phim cov yeeb nkab txuas txuas raws li API specifications.

◆ API 5CT Requirements rau Couplings

API 5CT specification npog cov kev cai tseem ceeb rau casing thiabtubing couplings:

Xaiv cov khoom siv

Raws li qib yeeb nkab ua ke, qib khoom sib txuas yuav tsum raug xaiv kom raug thiab txheeb xyuas los ntawm kev lees paub.

◆ Kev kuaj tshuab

Lub zog tensile, cuam tshuam toughness, sulfide kev ntxhov siab tawg tsis kam (rau qib siab dua) thiab lwm yam kev ntsuas kev ntsuas yuav tsum tau ua kom tiav thiab sau tseg.

◆ Tshuaj muaj pes tsawg leeg

Cov tshuaj muaj pes tsawg leeg ntawm txhua qib steel yog nruj tswj hwm.

◆ Dimensions thiab Tolerances

nruj tolerances yog teev rau txheej kab, phab ntsa thickness, ntev, straightness, threads ib nti, xov taper, thiab lwm yam.

◆ Xov Specifications

Cov ntaub ntawv sib txawv xws li pob tw, taper, thiab lwm yam muaj lawv tus kheej qhov ntev thiab geometry specifications.

◆ Kev kho cua sov

Normalizing, quenching, tempering yuav tsum tau txhais.

◆ Kev kos npe

Cov cim tshwj xeeb yog xav tau ntawm txhua qhov sib txuas rau kev taug qab.

◆ Khoom Specification Level

PSLs siab dua xws li PSL-2 lossis PSL-3 suav nrog cov kev xav tau ntxiv xws li kev tshuaj xyuas thib peb.

Coupling Manufacturing txheej txheem

Cov couplings feem ntau yog machined los ntawm seamless yeeb nkab lub cev seem los yog coupling blanks. Kev kub ntxhov tuaj yeem siv rau qee qib.

Kev tshuaj xyuas thiab kuaj

Dhau li ntawm lub zeb tus kheej kev tshuaj xyuas thiab kev sim, kev tshuaj xyuas thib peb uas muaj kev soj ntsuam cov txheej txheem thiab kev sim ua pov thawj tej zaum yuav xav tau rau qib PSL siab dua.

◆ Tshwj xeeb Couplings

API 5CT kuj tseem suav nrog cov kev sib txuas tshwj xeeb xws li kev sib txuas sib txuas sib txuas (ntau cov xov sib txawv ntawm txhua qhov kawg), reducer couplings (rau kev hloov cov kab sib txawv), foob lub nplhaib sib txuas, thiab cov couplings tshwj xeeb tapered.

◆ Kev sib txuas tsis sib xws

Thaum API 5CT tsom rau kev sib txuas ntawm cov xov thiab txuas txuas, qee cov hlua hlua tuaj yeem siv cov khoom sib cais tsis sib xws lossis cov kab sib txuas. Cov no muaj lawv tus kheej tsim qauv.

◆ Qhov cuam tshuam ntawm Cov Txheej Txheem Zoo

Cov ntsiab lus xws li H2S / CO2 cov ntsiab lus, kev kub siab / kub, kev thauj khoom dynamic, thiab lwm yam cuam tshuam rau kev xaiv cov khoom sib txuas thiab cov qauv tsim.

Casing thiabtubing couplingsua lub luag haujlwm tseem ceeb hauv kev ncaj ncees ntawm txoj hlua zoo nyob rau hauv ntau yam kev ua haujlwm. Xaiv thiab siv hom kev sib txuas tsim nyog rau API specifications yog qhov tseem ceeb rau kev ua haujlwm zoo thiab txhim khu kev qha.
