Casing couplings yog cov yeeb nkab fittings uas siv rau hauv cov kav dej sib txuas; lawv yog cov kav dej luv luv siv los txuas ob lub kav dej. Lawv kuj hu ua cov pob qij txha sab nraud. Vim lawv qhov yooj yim ntawm kev siv, casing couplings yog siv dav hauv kev tsim kho pej xeem, kev lag luam, kev ua liaj ua teb, thiab lwm yam.
Kev faib tawm
- Los ntawm Qib Steel: Casing couplings tuaj yeem muab faib ua ntau hom raws li qib steel, suav nrog tab sis tsis txwv rau J55, K55, N801, N80Q, L80 1, L80 9Cr, L80 13Cr, C90, T95, P110, Q125, thiab lwm yam.
- Los ntawm Specification: Casing couplings tuaj nyob rau hauv ntau yam specifications, feem ntau suav nrog 41/2, 5, 51/2, 65/8, 7, 75/8, 85/8, 95/8, 103/4, 113/4, 133/8, 16, 185/8, 20, thiab lwm yam. 7, 95/8, thiab 133/8.
- Los ntawm Xov Hom: Casing couplings tuaj nyob rau hauv ntau hom xov, nrog rau cov xov ntev round threads, luv round threads, trapezoidal threads, thiab tshwj xeeb threads. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tsis yog tag nrho cov casing couplings muaj nyob nrog cov xov ntev. Piv txwv li, casing couplings ntawm qhov ntau thiab tsawg 103/4, 113/4, 133/8, 16, thiab 185/8 tsuas yog muaj nrog luv luv round threads thiab trapezoidal threads.
Muaj nuj nqi
Lub luag haujlwm tseem ceeb ntawm casing couplings yog txuas ob lub casings, kom ntseeg tau tias kev sib txuas ceev thiab ruaj ntseg. Hauv kev lag luam roj thiab roj, casing couplings yog qhov tseem ceeb hauv kev ua haujlwm drilling thiab ua tiav.
Daim ntawv thov:
Hauv kev xyaum ua engineering, casing couplings feem ntau yog siv hauv cov xwm txheej hauv qab no:
- Kev sib sib zog nqus zoo casing raug tshem tawm: Thaum siv lub spindle - hom hanger, lub coupling ncaj qha bears lub luj ntawm lub casing hlua, ua ib tug hlau - mus rau - hlau foob.
- Cov qauv zoo sib xws: Kab rov tav qhov dej thiab cov qhov dej txuas ntxiv yuav tsum muaj siab -torsion couplings nrog torque muaj peev xwm ua tau raws li API cov qauv.
- Corrosive ib puag ncig: 13Cr couplings ua tau raws li API cov qauv rau kev pab cuam lub neej hauv CO₂/H₂S- muaj cov roj thiab roj.
- Cov kev xav tau nrawm nrawm: yooj yim snap- haum couplings tso cai rau ib leeg- kev sib txuas ua haujlwm.
