Hom Casing Couplings
Casing couplings yog categorized los ntawm lawv cov xov profile thiab ntev:
| Hom kev sib txuas | Lub Npe | Kev piav qhia |
| STC | Luv Round Xov | Nta ib puag ncig xov profile nrog 8 threads ib nti. Siv rau cov hlua luv luv uas qhov siab nruj tsis yog qhov kev txhawj xeeb tseem ceeb. |
| LTC | Ntev Round Xov | Tib cov xov profile zoo li STC tab sis qhov sib txuas yog ntev dua, muab cov xov txuas ntxiv rau lub zog tensile ntau dua. |
| BTC | Buttress Xov | Features square / trapezoidal xov profile. Tsim los tswj cov axial siab nro thiab zoo dua to hauv cov dej tob. |
| Tshwj xeeb Clearance | - | Tshwj xeeb machined (me me OD) couplings rau siv nyob rau hauv nruj wellbores qhov twg txheem couplings yuav tsis haum. |

Daim ntawv thov ntawm API 5CT Couplings
Kev sib txuas:Muab kev ruaj ntseg mechanical txuas ntawm cov yeeb nkab txuas.
Siab Sealing:Tuav cov pa tawm- pov thawj foob nyob rau hauv siab sab hauv thiab sab nraud.
Kev them nyiaj yug:Nqa lub luj ntawm tag nrho cov casing los yog tubing hlua ncua nyob rau hauv lub qhov dej.
Corrosion Resistance:Tshwj xeeb kho couplings yog siv nyob rau hauv "Sour Service" (H2S ib puag ncig).
Txheej txheem ntawm API 5CT Couplings
Kev tsim cov couplings yog qhov nyuaj dua li cov yeeb nkab txheem vim yog qhov xav tau ntawm cov xov:
Raw Material Xaiv:Siv API 5CT raws li cov khoom sib txuas (hnyav- cov kav dej tsis sib haum).
Txiav:Txiav cov khoom sib txuas rau hauv qhov ntev raws li cov yeeb nkab txoj kab uas hla thiab xov hom.
Kev kho cua sov:Normalizing los yog quenching & Tempering kom ncav cuag cov neeg kho tshuab qib (piv txwv li, N80, P110).
Xov xov:CNC machining ntawm cov xov sab hauv (EUE, NUE, BTC, STC, lossis LTC).
Kev kho deg:
Phosphating:Rau cov qib qis- qib couplings los tiv thaiv xeb thiab txhim kho lubrication.
Copper Plating:Feem ntau siv rau qib siab - qib lossis kev sib txuas hwm zoo los tiv thaiv cov xov paj.
Kev tshuaj xyuas:Xov gauging, Magnetic Particle Inspection (MPI), thiab Ultrasonic Testing (UT).
Marking & Painting:Siv cov lej xim thiab API monograms.

FAQ
Api 5ct Tubing Coupling yog dab tsi thiab nws ua haujlwm li cas?
IbAPI 5CT Tubing Couplingyog ib tug luv luv, internally threaded yeeb nkab tes tsho siv los koom ob lengths (kos) ntawm oilfield tubing. Nws ua raws li poj niam connector (theLub thawv) uas txuas tus txiv neej xaus (thePins) ntawm cov kav dej.
Nws ua haujlwm li cas:
Mechanical kev sib txuas:Nws yog screwed rau ntawm cov yeeb nkab kawg siv cov torque tshwj xeeb. Vim tias nws yog ua los ntawm siab - lub zog steel (kev sib tw lossis tshaj cov yeeb nkab qib), nws ruaj ntseg tuav qhov hnyav ntawm tag nrho cov hlua hlua dai rau hauv qhov dej.
Siab Sealing:Nws nta tapered threads (xws liEUElos yogNUE). Raws li kev sib txuas yog nruj, cov xov wedge ua ke los ua ib lub hlau-rau- hlau foob.
Kev Tiv Thaiv Leak:Cov roj tshwj xeeb hu ua"xov dope"yog siv ua ntej sib dhos. Qhov no lubricates cov xov los tiv thaiv kev puas tsuaj (galling) thiab ua kom muaj qhov khoob khoob khoob kom ntseeg tau tias muaj roj- nruj seal tiv thaiv lub siab sab hauv.
Api 5ct Tubing Coupling zoo li cas piv rau lwm txoj kev?
Muab piv rau cov kev xaiv ib txwm muaj xws li cov qauv kev lag luam xov lossis vuam,API 5CT Tubing Couplingsmuab ntau qhov zoo sib xws:
Siab zog:CovKev ntxhov siab sab nraud (EUE)tsim txhawb kev sib txuas, ua rau nws muaj zog dua cov yeeb nkab lub cev nws tus kheej. Qhov no tso cai rau nws los txhawb nqa kilometers ntawm hnyav tubing hlua, whereas txheem threads feem ntau tsis muaj zog cov yeeb nkab phab ntsa.
Superior Sealing:Precision tapered threads tsim ibhlau-rau- hlau foobuas tseem muaj roj- nruj nyob rau hauv siab heev (10,000+ psi) thiab cua sov, outperforming tsoos industrial gaskets uas yuav degrade.
Kev Ua Haujlwm Flexibility:Threaded couplings pub rauceev sib dhos thiab disassemblyntawm lub qhov taub. Qhov no ua rau kev saib xyuas thiab cov yeeb nkab rov qab tau yooj yim dua piv rau cov pob qij txha ruaj khov.
Ntiaj teb no Standardization:Raws li ib tugunified thoob ntiaj teb tus qauv, API couplings los ntawm cov tuam txhab sib txawv yog 100% sib hloov, txo qhov kev yuav khoom nyuaj thiab cov nqi khoom muag.
